Mexican Bark Paper: Evidence of History of Tree Species Used and Their Fiber Characteristics. The use of bark fibers (secondary phloem) for the manufacture of the Mexican bark paper called amate can be traced back to the pre–Hispanic period. This paper was used extensively during this period, and for the last four decades has been produced as a handicraft by the Nahnus of San Pablito village in the Sierra Norte de Puebla region of Mexico. Due to the high demand for this product, new species are now used as a source of bark and specific phases of the traditional production technique have been modified. The focus of this study was to register all the species that have been used for bark paper manufacturing, both traditionally and more recently, and to analyze their fiber characteristics, mainly fiber length and lignin content. The main questions addressed by this study were: a) Which species have been used for bark paper production, both prior to and following its commercialization as a handicraft? b) Which anatomical and histochemical fiber characteristics of these species enable their use for bark paper production, regardless of taxa? And c) is there a relationship between the adoption and use of new species and recent changes in traditional paper making techniques? Based on an ethnobotanical study, a list of 13 species used for bark paper production was compiled and bark samples from each species were collected for phloem anatomical and histochemical analysis. Artisans and local healers were also asked to determine the main characteristics of each fiber and paper type. The results demonstrate that bark from currently used species differs anatomically and histochemically from species used during the pre–Hispanic period and until a few decades ago, and in terms of the quality assessed by local healers and artisans. Among other characteristics, the fibers of the new species have higher lignin content than the traditional ones, and this constitutes the main reason behind the modification of certain phases of the traditional paper making process.

The paper report the oral traditional knowledge of wild medicinal plants usage by the indigenous ethnic tribal community from the Peren district of Nagaland, India in the Indo-Burma Hotspot. The pioneer study was based on the semi-structured interview of locals (N = 240) in the 12 villages of the Peren District during 2014 ‐ 2018. In total, 179 ethnomedicinal plants from 140 genera and 72 families were documented and identified. The medicinal plants were used for the treatment of 96 different ailments grouped into 18 categories. The medicinal plants also showed high versatile nature with 85 species reported to treat five / eleven different ailments, respectively. The ethnobotanical information obtained from the field documentation will contribute in the development of potential drugs in the future from the diverse wild medicinal plants of the region and contribute towards the preservation of the oral tradition that is disappearing.

Citation studies have become an important tool for understanding scientific communication processes, as they enable the identification of several characteristics of information-retrieval behavior. This study seeks to analyze citation behavior using two popular ethnobotany articles, and our analysis is guided by the following question: when an author references a work, is he pointing out the work’s theoretical contribution, or is bias a factor in citing this reference? Citation analysis reveals an interesting phenomenon, as the majority of citing texts do not consider the theoretical contributions made by the articles cited. Two possible conclusions can be drawn from this scenario: (1) citing authors read the original texts that they cite only superficially, and (2) the works cited are not read by the vast majority of people who reference them. Thus, it is clear that even with sufficient access to reference texts; ethnobotanical studies highlight elements less relevant to the research and reproduce discussions in a non-reflective manner.

Since the outbreak in December 2019, in Wuhan (China) of COVID-19, approved drugs are still lacking and the world is seeking effective treatment. The purpose of this article is to review the medicinal plants with potential to be used as complementary therapies against COVID-19. Bibliographic information was searched in several databases (Google Scholar, PubMed, Scopus, ScienceDirect, PROTA, ResearchGate and GLOBEinMED), to retrieve relevant papers on (1) plants used to manage common symptoms of COVID-19, (2) plant secondary metabolites with confirmed inhibitory effects on COVID-19 and (3) plants exhibiting pharmacological activities of relevance for COVID-19 management. A total of 230 species was recorded as potential source of ingredients for the fight against the 2019 novel corona virus. Of these species, 30 contain confirmed antiCOVID-19 secondary metabolites, 90 are used traditionally to manage at least 3 common symptoms of COVID-19, 10 have immunostimulant activity, 52 have anti-inflamatory activity, 14 have antiviral properties and 78 species are documented as used to treat malaria. A PCA analysis showing cluster formatting among the recorded species indicates 4 groups of species and an array of possibility of using individual species or a combination of species for their complementary effects. The authors argue that Cameroonian medicinal plants can be of potential contribution to the fight against COVID-19. Further applied research is needed to provide more scientific evidence for their efficacy, to establish standard formulations and clinical studies as part of efforts to develop therapies for COVID-19.

Ethnographic literature documents the pervasiveness of plant-management strategies, such as prescribed burning and other kinds of cultivation, among Northwest Peoples after European contact. In contrast, definitive evidence of precontact plant management has been elusive. Documenting the nature and extent of precontact plant-management strategies has relevance to historians, archaeologists, managers, conservationists, forest ecologists, and First Nations. In this paper, we summarize the various lines of evidence that have been, or could be, used to document ancient cultivation in the northwest of North America. We organize this discussion by the ecological consequences of ancient plant-management practices and their documented or potential visibility in the paleo-, neo-ecological, and archaeological records. Our review demonstrates that while finding evidence of ancient plant management can be difficult, such evidence can be found when innovative research methods are applied. Further, when various independent lines of evidence are compiled, reconstructions of past plant-management strategies are strengthened considerably.

This paper discusses local understanding of plants and habitats, based on the linguistic evidence [terms for plants and (or) habitats] gathered from ethnobotanical and ethnoecological field work conducted with several Dene Nations of the Canadian northwestern boreal forest and adjacent regions. Nations involved in the study include Gwich’in (Mackenzie Delta Region), Sahtú’otine’ (Great Bear Lake), Kaska Dena (southern Yukon), and Witsuwit’en (northwest British Columbia). Key plant-related habitats include meadow, “swamp”, forest, “willows”, and “brush”. The ethnobotanical classification of willows is explored in conjunction with the explanation of the Dene habitat concept. In local classifications, ‘willow’ is not co-extensive with the genus Salix , but includes a variety of medium to tall woody shrubs that lack either conspicuous flowers, ‘berries’, or thorns; these may include shrubby species of Salix, Alnus , Cornus , and Betula . Shoreline and alpine environments are also discussed as plant habitats. Dene use of alpine environments and resources is ancient, according to the results of recent alpine ice patch research in the Yukon region. The Human dimensions of habitat knowledge are presented. Indigenous concepts of plant taxa and of landscape associations or habitats may differ substantially from those of scientific botany and ecology, and are based in a holistic and interactive ethnoecology.

This paper presents the results of an experiment replicating traditional Interior Salish pit-cooking methods to process balsamroot ( Balsamorhiza sagittata (Pursh) Nutt.), a former food staple that contains the complex carbohydrate inulin. Analysis of fresh and cooked balsamroot samples reveals that with sufficient heat, moisture, and the release of volatile organic acids, inulin is hydrolyzed during pit cooking. This process converts complex carbohydrates into simple ones, resulting in an increase of 250% in the energy provided by simple sugars. When the average energy contributions of protein, simple and complex carbohydrates are tallied, the net result is an energy gain of approximately 65% between fresh and pit-cooked balsamroot. This research demonstrates the effectiveness of ancient pit-cooking practices in transforming unpalatable and inedible root resources into sweet-tasting, highly digestible sources of carbohydrate energy and supports my assertion that this processing technology was a key component of the wild plant food production systems of Interior Salish Peoples.

Knowledge and practices of indigenous peoples relating to local plants used for food, medicine, materials, and other purposes are threatened in many parts of the world. The reasons for declining knowledge and use of traditional resources are complex and multifaceted. We review a series of case examples of culturally valued food plants in British Columbia and identify a suite of interacting social and environmental factors that have resulted in decreased use of and dwindling cultural knowledge about these plants over the past 150 years. Reasons for this loss include compounding influences of changing knowledge systems owing to religious conversion and residential schools, loss of indigenous languages, loss of time and opportunity for traditional practices owing to participation in the wage economy, increasing urbanization of indigenous populations, loss of access to traditional resources, restriction of management practices for sustaining these resources, and most recently, forces of globalization and industrialization. Efforts to renew and restore traditional practices and relationships with plants and environments must recognize the cumulative effects of these factors and find ways to retain and reinforce the knowledge and practices still held by individuals and communities, to reverse some of the negative influences on cultural retention, and to develop new, relevant, and effective ways to revitalize languages, cultures, and ethnobotanical knowledge within contemporary contexts.

The traditional medicinal uses of plants by the Inuit of Nunavut, Canada were analysed using quantitative ethnobotanical methodology. Traditional knowledge was collected during interviews with volunteer Inuit informants and from historical interview transcripts. A total of 13 different species were mentioned, which included 1 moss, 1 algae, 1 fungus, and 10 vascular plant species. An informant consensus index value, Fic > 0.7, for many use categories revealed a high level of informant agreement, consistent with a well-preserved oral tradition and low flora biodiversity. The documentation of this information is a useful tool for the preservation of Inuit culture, as well as for the integration of Inuit traditional medicine with Western medical practices in Arctic communities (Inuit Qaujimajatuqangit, IQ).

The Buyi are a socio-linguistic group in Yunnan Province of southwest China that have a long history of using medicinal plants as part of their indigenous medical system. Given the limited written documentation of the Buyi indigenous medical system, the objective of this paper is to document the medicinal plants of the Buyi and associated traditional knowledge and transmission. Field research was conducted in four villages in Lubuge Township of Luoping County in Yunnan Province using ethnobotanical methodologies including participatory observation, semi-structured interviews, key informant interviews, and focus group discussions to elicit information on medicinal plants. In total, 120 informants (including 15 key informants who are healers) were interviewed. This study found that a total of 121 medicinal plant species belonging to 64 families are used by the Buyi including by local healers to treat different diseases. Among the medicinal plants recorded in this study, 56 species (46%) have not previously been documented in the scientific literature as having medicinal value, highlighting the pressing need for ethnobotanical documentation in indigenous communities. The most frequently used medicinal part was the leaf (24.9% of documented plants), and the most common preparation method was decoction (62.8% of medicinal). Medicinal plants were mainly used to treat rheumatism (12.4% of plants), trauma and injuries (9.6%). The documented plants are also used for other non-medicinal purposes including food, fodder, fencing, and ornamental. In addition, 35 of the medicinal plants are considered poisonous and are used by local Buyi healers for medicine. The traditional Buyi beliefs and practices associated with the documented medicinal plants likely contributes to their conservation in the environments and around Buyi communities. This study further highlights that ethnomedicinal knowledge of the Buyi is at risk of disappearing due to increased introduction and use of modern medicine in Buyi communities, livelihood changes, rapid modernization, and urbanization. Research, policy, and community programs are urgently needed to conserve the biocultural diversity associated with the Buyi medical system including ethnobotanical knowledge towards supporting both environmental and human wellbeing.

The study area is inhabited by Gond tribes. Tribals and most of forest dwellers mainly depend on plants and plant product for their food. This study reveals that the ethnic people and forest dwellers have considerable traditional knowledge of wild edible plants and their utilization. This paper report is based on survey, interview and field work studies on wild edible plants used by tribals and rural people of Arjuni/Mor Taluka, Gondia District, Maharashtra State, India during March 2016 - March 2018. A total of 71 plant species belonging to 63 genera and 39 families have been recorded as wild edibles in the study areas, of which trees are ranked first with 36 species, followed by herbs, climbers and shrubs with 22, 7 and 6 species respectively. Among the 71 species, 43.2% contribute as vegetables by their fruit, 22.22 % by leaf, 12.34% by seed or grain, 8.64% by root or tuber, 6.17% by stem, bark or sap, 6.17% by flower and 1.23% by whole plant. It is evident from the survey that most of the species of wild edibles are used as vegetable/chutney(49.33%), followed by raw/ripe fruits(45.33%), pickles(4%), roasted seeds(1.33%).

In the Qinba mountainous area of Central China, pig farming has a significant impact on the growth of the rural economy and has substantially increased farmer incomes. Traditional knowledge plays an important role in the selection of forage plant species for pig farming by local people. This study aimed to identify the forage plants used for pig feeding and to catalog indigenous knowledge regarding their use. During 2016 and 2017, ethnobotanical surveys and inventories were conducted in Zhuxi County, Hubei Province, China. Data were collected using semi-structured interviews, key informant reports, free listings, guided field walks, and participatory observations with 77 households in 16 villages in 13 towns/townships. The obtained data were analyzed using a relative frequency citation (RFC) index. Overall, 145 wild forage plants from 91 genera and 31 families were recorded. The most cited families were Asteraceae, Polygonaceae, Urticaceae, Amaranthaceae, Fabaceae, Cruciferae, Caryophyllaceae, and Lamiaceae. Whole plants (75.9%) and tender leaves (12.4%) were the most frequently used parts of the plants. Most of the forage plants were herbaceous (88.9%). Almost all forage plants could be collected throughout the year (62.7%). Raw and cooked were the two main preparation methods. The most frequently cited species were Taraxacum mongolicum, Bidens pilosa, Sonchus oleraceus, Pilea verrucosa, and Pilea pumila var. obtusifolia. A total of 14 species were identified as the top forage plants in Zhuxi County based on their RFC values (RFC value greater than 0.5). Local people possess rich traditional knowledge about the utilization and management of forage plants for pig feeding. However, the maintenance of this traditional knowledge may be seriously threatened by changes in pig feeding modes and the lack of successors. Appropriate strategies and action plans have been suggested for the conservation of traditional knowledge associated with biodiversity and the sustainable use of forage species resources. These include 1) taking targeted measures to protect forage resources and associated traditional knowledge; 2) strengthening research on the forage plants with the highest RFC values for nutritional value, digestibility, other functions, and ecological status; and 3) enhancing the identification of poisonous forage plants.

Herbal teas composed of locally occurring plant species have long been used as the primary form of health care in Qingtian County, Zhejiang Province, China. However, large-scale emigration overseas and an aging population threaten the conservation of traditional knowledge of these herbal teas. Traditional knowledge about the plants used for these herbal teas is not well documented in Qingtian, despite their widespread use. The aim of this study was to assess the plant-cultural diversity of plants used as herbal teas, and to point out the prospective value of herbal teas used by Qingtian people. This study was conducted using semi-structured interviews, as well as field and market surveys. Forty-three local informants were interviewed. We recorded plant resources, plant parts used, local names, and medicinal uses. Quantitative ethnobotanical indices, including cognitive salience (CS), frequency of citation (FC), index of informant consensus (Fic) and use value (UV), were calculated to analyze the level of representativeness and relative importance of plants used in herbal teas. One hundred and twenty-nine species belonging to 75 families and 113 genera were reported to be used in herbal tea, with Compositae being the richest family. Whole plants are most commonly used to make herbal teas (66.7%). In this study, informants reported that 92.2% of plant species used in herbal teas are wild. The most utilized herbal preparation form is dry/fresh. Informants reported that herbal teas are used to treat 31 ailments. Our results show that the highest representativeness, based on CS and FC, was recorded for species Actinidia eriantha. Based on UV, the top five most used species are Goodyera schlechtendaliana, Plantago asiatica, Prunella vulgaris, Lophatherum gracile and Leonurus japonicus. The highest Fic was cited for dental medicine. This study helps document the status of current herbal teas in Qingtian. The use value and traditional knowledge of herbal teas have provided basic data for further research focused on bioactivity studies and sustainable utilization of the most important species.

Dragon Boat Festival herbal markets in the Qianxinan Buyi and Miao Autonomous Prefecture of southwestern Guizhou have a long well-conserved history. These markets, which are a feature of Buyi and Miao traditional medicines, contain a rich diversity of medicinal plants and traditional medical knowledge. Today, people in southwestern Guizhou still believe that using herbs during the Dragon Boat Festival prevents and can treat disease. In this study, we identified the fresh herbal plants sold at the herbal markets of Xingren City and Zhenfeng County in Qianxinan Buyi and Miao Autonomous Prefecture and quantified their importance. We identified 141 plant species (belonging to 114 genera and 61 families). The plant family with the most species was Asteraceae (14 species). Informants reported that most medicinal plants are herbaceous, with 95.7% of plants used for decoction and 30.5% used for medicinal baths. Medicinal plants are most commonly used to treat rheumatism, injury, and abdominal diseases. The utilization frequency index and relative importance values indicated that Artemisia argyi and Acorus calamus are the most important plants sold at herbal markets during the Dragon Boat Festival. The price of medicinal materials sold in the market may serve as an indicator of the conservation status of species in the region. These findings indicate that the Dragon Boat Festival herbal markets in the Qianxinan Buyi and Miao Autonomous Prefecture fully embodies the characteristics of indigenous ethnomedicine and culture, and also exhibits the diversity of plant resources. We recommend that rare and endangered plants in this region be domesticated and protected.

Most people in the world still use medicinal plants to treat and prevent disease. In Anatolia, studies have shown that people have used plants for centuries to treat many diseases. Herbal markets play an important role in the supply of medicinal plants and the transmission of cultural heritage. In this study, we investigated the traditional uses of medicinal plants traded in Kahramanmaraş herbal markets. We also analyzed the threats that may arise from the use of medicinal plants and the measures that can be taken to protect these plants. For these purposes, ethnomedicinal data were collected using semi-structured and open-ended questionnaires of herbalists and local people. Ethnobotanical indices (e.g., Relative Frequency of Citation, Use Value, Relative Importance, and Informant Consensus Factor) were used to quantify the use and cultural importance of medicinal plants sold at Kahramanmaraş herbal markets. We identified 62 taxa (11 imported) of plants that are used in traditional folk medicines. The top three plant taxa sold per year by herbalists at Kahramanmaraş herbal markets are Licorice (Glycyrrhiza glabra; 140 kg), Thyme (Thymus sp.; 109 kg), and Carob (Ceratonia siliqua; 106.5 kg). The plant parts and mode of utilization used most are leaves (28 reports) and infusion (36 reports), respectively. The highest ICF value was detected for endocrine system ailments (0.78), and the next highest two values were lymphatic system (0.75) and respiratory system ailments (0.72). We determined that Urtica dioica, G. glabra, Thymus sp., Mentha x piperita have widely traditional uses, with high ethnobotanical index values and use reports. In addition, according to IUCN criteria, 26 of 62 taxa identified in the research are under threat to various degrees on a global scale., Graphical abstract Image 1

The Naxi of Northwest Yunnan, China use medicinal plants to treat skin conditions related to traditional lifestyles in extreme environments. However, modernization endangers both the medicinal plants used to treat skin conditions and traditional knowledge. Therefore, investigation and documentation of the medicinal plants used and associated traditional knowledge is necessary. In this study, we conducted an ethnobotanical survey in 12 Naxi communities in Northwest Yunnan. For this purpose, we used semi-structured surveys to interview 840 informants from Naxi communities. We used informant consensus factor and use frequency as quantitative indices to evaluate the importance of medicinal plant species. A total of 161 medicinal plant species belonging to 69 families were documented. The highest informant consensus factor (ICF) values were recorded for skin nourishing (ICF = 0.849), frostbite and chapped skin (ICF = 0.833). These skin treatments are highly related to the environment and lifestyle of Naxi communities. The main active compounds of plants used to treat skin conditions in Naxi communities are known to have skin-treating properties. This study reveals that the skin conditions treated by the Naxi are associated with traditional medicine culture and social economic development. In addition, this study uses ethnobotanical indices to explain how skin condition treatments are linked to the natural environment of Naxi communities.

Hematophagous invertebrates such as mosquitoes, leeches, mites, ticks, lice and bugs cause various problems for humans. Considering reports on insecticide resistance and requirements for improved environmental and toxicological profiles, there is a continuing need to discover and develop new insecticides and repellents. Ethnobotanical surveys of traditional plant-based repellents provide a direct method of identifying plants for potential use. During five field surveys in Bulang, Jinuo and Lahu villages between August 2018 and July 2019, semi-structured interviews were conducted with 237 informants (151 male, 86 female; mean age 63). Frequency of citation, use value, informant consensus factor and Jaccard index were employed to statistically analyze the collected data. A total of 709 use reports relating to 32 plant species and 71 remedies were collected. Similarities and differences between the three groups, as well as the Dai and Hani of Xishuangbanna, who were studied earlier, were shown through network analysis. These five ethnic groups living in the same area have a common understanding of traditional botanical knowledge against hematophagous invertebrates, but each group also possesses unique knowledge. Recording and protecting this traditional knowledge is potentially useful for protecting this cultural diversity and related biodiversity and can also have important practical applications. In this study, traditional knowledge provided us with many new potential plants for follow-up research for the development of new insecticides and repellents, among which Artemisia indica, Nicotiana tabacum and Clausena excavata are the most promising.

Cistanche deserticola is an important medicinal plant in Mongolia. Despite its significant role in local healing systems, little traditional knowledge had been reported. The present study investigated folk names of C. deserticola and other species of the same community in Umnugobi Province, South Gobi region of Mongolia, based on ethnobotanical approaches. The high correspondence between folk names and scientific names of plant species occurring in Cistanche-associated community shows the scientific meaning of folk nomenclature and classification in Mongolia. The Mongolian and folk names of plants were formed on the basis of observations and understanding of wild plants including their morphology, phenology and traditional uses as well. Results from this study will support the conservation of C. deserticola itself, a rare and endangered plant species listed in the Monglian Red Data Book. Our documentation of folk nomenclature based on 96 plant species in the Cistanche community, as a part of traditional knowledge associated with biodiversity, will be very helpful for making strategy of plant biodiversity conservation in Mongolia.

Background Indigo-dyed textiles have been central to the cultural identity of Landian Yao (literally “blue clothes Yao”) people in Southwest China for centuries, driving a significant local market for naturally dyed indigo cloth. In the past two decades, local indigo production for traditional textiles has declined for several reasons: Firstly, the younger generation of Landian Yao has shifted to using western style jeans and T-shirts. Secondly, due to its labor-intensive nature. In contrast, at a global scale, including in China, there has been a revival of interest in natural indigo use. This is due to a growing awareness in the fashion industry about human and environmental health issues related to synthetic dye production. Ironically, this new awareness comes at a time when traditional knowledge of indigo dyeing is being lost in many places in China, with weaving and use of natural dyes now limited to some remote areas. In this study, we recorded indigo dyeing processes used by Landian Yao people and documented the plant species used for indigo dyeing. Methods Field surveys were conducted to the study area from September 2015 to November 2016, supplemented by follow-up visits in July 2018 and November 2018. We interviewed 46 key informants between 36 and 82 years old who still continued traditional indigo dyeing practices. Most were elderly people. Semi-structured interviews were used. During the field study, we kept a detailed account of the methods used by Landian Yao dyers. The data were then analyzed by using utilization frequency to determine the best traditional recipe of indigo dye extraction. All the specimens of documented species were collected and deposited at the herbarium of Kunming Institute of Botany. Results Our results showed that indigo dyeing was divided into two main steps: (1) indigo pigment extraction and (2) dyeing cloth. The general procedures of indigo dye extraction included building or buying a dye vat, fermentation, removal of the leaves of indigo producing plant species, addition of lime, oxygenation, followed by collection, and the storage of the indigo paste. The procedures of dyeing cloth included preparing the dye solutions, dyeing cloth, washing, and air drying. It is notable that Landian Yao dyers formerly only performed the dyeing process on the goat days in the lunar calendar from June to October. After comparing the range of local indigo extraction methods, our results showed that the following was best of these traditional recipes: a indigo-yielding plant material to tap water ratio of 30 kg: 200 l, lime 3 kg, a fermentation time of 2–3 d, aeration by agitation for up to 60 min, and a precipitation time of 2–3 h. Our results show that 17 plant species in 11 families were recorded in the indigo dyeing process. With the exception of the indigo sources, only Dioscorea cirrhosa Lour. and Artemisia argyi H.Lév. & Vaniot were previously recorded in dyeing processes. Other species given in this paper are recorded for the first time in terms of their use in the indigo dyeing process. In the study area, Landian Yao men were in charge of indigo dye extraction, and the women were responsible for dyeing cloth. Conclusions The Landian Yao has completely mastered the traditional indigo dyeing craft and are one of the well-deserved identity blues. Indigo production from plants using traditional methods is a slow process compared to synthetic dyes and is not suitable for modern and rapid industrial production. Therefore, our study records the detailed information of traditional indigo dyeing to protect and inherit it. Strobilanthes cusia (Nees) Kuntze is the main indigo source in Landian Yao that is widely used in the world and can be commercially exploited as an indigo plant. For commercial and environment benefits, we suggest that producing natural indigo for the commercial market is a good choice.

The far Southwest Ethiopians transplant wild plant species to their gardens. One of such plant is the Dioscorea that we studied to assess the knowledge of wild yam and process of domestication. The study links two types of evidence to obtain insight about the process of yam domestication. We analyze two data sets derived from (1) ethnobotanical survey using 231 semi-structured interviews; and (2) morphological study in 47 yam accessions. Our study revealed that domestication is still active in some villages. Knowledge of yam domestication was shared by 44% of the farmers’ even by those that have never practiced its domestication. Farmers who can describe the trend of domestication and the morphotypes of domesticate represented 21 and 28%, respectively. Farmers who have recent transplants in their garden varied from 4% in Bench to 10% in Sheko. The domestication process described by the two ethnic groups is similar. The duration of domestication can take up to six years, but with most of the individuals, it only takes three to five years. By linking the two types of evidence, two evolutionary processes are distinguished: (1) populations of recent domesticate expressing a domestication syndrome possibly belongs to the wild D. abyssinica or D. praehensilis, and (2) plants of incipient domesticate that might be derived from volunteers or diverse types of hybrids. Each of these processes can lead to integration of wild genotypes into the cultivated gene pool, and hence, enhance genetic diversity of cultivated yams. The domestication practices of traditional farmers should thus be taken into account if yam conservation and improvement plans need to be established.

Objective:To identify wild plants used as food and assess their frequency of consumption over a year in a region of Tunisia where agriculture is undergoing a major transformation from smallholder farming to an intensive high-input agricultural system.Design:Qualitative ethnobotanical study followed by a survey of women’s frequency of consumption of wild plants conducted using FFQ at quarterly intervals.Setting:Sidi Bouzid governorate of central Tunisia.Participants:Mixed-gender group of key informants (n 14) and focus group participants (n 43). Survey sample of women aged 20–49 years, representative at governorate level (n 584).Results:Ethnobotanical study: thirty folk species of wild edible plants corresponding to thirty-five taxa were identified by key informants, while twenty folk species (twenty-five taxa) were described by focus groups as commonly eaten. Population-based survey: 98 % of women had consumed a wild plant over the year, with a median frequency of 2 d/month. Wild and semi-domesticated fennel (Foeniculum vulgare Mill. and Anethum graveolens) was the most frequently consumed folk species. Women in the upper tertile of wild plant consumption frequency were more likely to be in their 30s, to live in an urban area, to have non-monetary access to foods from their extended family and to belong to wealthier households.Conclusions:In this population, wild edible plants, predominantly leafy vegetables, are appreciated but consumed infrequently. Their favourable perception, however, offers an opportunity for promoting their consumption which could play a role in providing healthy diets and mitigating the obesity epidemic that is affecting the Tunisian population.

Objective: An ethnobotanical survey on the medicinal plant species marketed in Mashhad city, northeastern Iran, was conducted in order to document traditional medicinal knowledge and application of medicinal plants. Materials and Methods: This study was undertaken between 2011 and 2012. The indigenous knowledge of traditional healers used for medicinal purposes were collected through questionnaire and personal interviews during field trips. Ethnobotanical data was arranged alphabetically by family name followed by botanical name, vernacular name, part used, folk use, and recipe. Correct identification was made with the help of the various Floras and different herbal literature at the Ferdowsi University of Mashhad Herbarium (FUMH). Results: The present investigation reported medicinal information for about 269 species, belonging to 87 vascular plant families and one fungus family. The most important family was Lamiaceae with 26 species, followed by Asteraceae with 23, Fabaceae with 20, and Apiaceae with 19. Herbal medicine uses reported by herbalists was classified into 132 different uses which show significant results to treat a wide spectrum of human ailments. Plants sold at the market were mostly used for digestive system disorders, respiratory problems, urological troubles, nervous system disorders, skin problems, and gynecological ailments. Conclusion: This survey showed that although people in study area have access to modern medical facilities, a lot of them still continue to depend on medicinal plants for the treatment of healthcare problems. The present paper represents significant ethnobotanical information on medical plants which provides baseline data for future pharmacological and phytochemical studies.

The results of an ethnobotanical study conducted in the pristine village of Prokosko Lake (Vranica Mountain, Bosnia and Herzegovina) in summer 2007 is presented. Informal interviews involving 12 informants known as “traditional healers” provided data from 43 plants used in 82 prescriptions. The applied plants were used for a broad spectrum of indications. The most frequent were gastro-intestinal tract ailments, blood system disorders, skin ailments, respiratory tract ailments and urinary-genital tract ailments. The most frequent preparation was an infusion. Other often used preparations were ointments or balms and decocts. The special Bosnian balms known as “mehlems” were prepared from freshly chopped or freshly pressed herbal parts of various plant species. Warmed resins from Abies or Picea species, raw cow or pig lard, olive oil and honey served as basis. The traditional doctors, who usually worked as a team, enjoyed such a good reputation that people from all over the country were visiting in search of alternative ways to cure their ailments and diseases. The practical techniques applied by the healers and some of their attitudes and values are reported.

Diospyros blancoi A. DC. is an evergreen tree species of high-quality wood. Mabolo, the fruit of this plant, is popular among the natives in Taiwan, but its potential in economic use has not been fully explored. Mabolo has a rich aroma. Of the 39 different volatile compounds isolated, its intact fruit and peel were found to both contain 24 compounds, whereas the pulp contained 28 compounds. The most important aroma compounds were esters and α-farnesene. Our data show that mabolo is rich in dietary fiber (3.2%), and the contents of other nutrients such as malic acid, vitamin B2, vitamin B3, folic acid, pantothenic acid, and choline chloride were 227.1 mg/100 g, 0.075 mg/100 g, 0.157 mg/100 g, 0.623 mg/100 g, 0.19 mg/100 g, and 62.52 mg/100 g, respectively. Moreover, it is rich in calcium and zinc; the contents of which were found to be 42.8 mg/100 g and 3.6 mg/100 g, respectively. Our results show that D. blancoi has the potential to be bred for a novel fruit.

Quantitative methods have been used in many ethnobotanical studies, and such as the determination of the utility value of the species (Prance et al, 1987; Pinedo-Vasquez et al, 1990), its relative importance to the cul ture or community (Amorozo and G?ly, 1988; Phillips and Gentry, 1993a, 1993b; Albuquerque and Chiappeta, 1994/1995), and the cultural signifi cance of plants to many human groups (Turner, 1988; Stoffle et al, 1990; Silva, 1997), among others. Those studies aimed to establish the role and importance of plants, rescue traditional botanical knowledge, and offer al ternatives for the conservation of the plant resources and the culture of the groups involved in the studies. The adoption of quantitative methods broad ens ethnobotanical studies by allowing the evaluation of data obtained with surveys as well as the comparison of data from other studies. The present study evaluates the importance of plants for communities located in the metropolitan area of Recife (RMA), Coastal-Forest Zone of Pernambuco, Brazil, through the Index of Cultural Significance (Stoffle et al, 1990). The data obtained indicate the ways the plants are used in each of the commu nities and how these can be influenced by the social, cultural, and economic status of individuals in those communities.

This paper provides significant ethnobotanical information on pharmaceutical plant uses, where some degree of acculturation exists, so that there is urgency in recording such data. The aim of this work is to catalogue, document, and make known the uses of plants for folk medicine in Dehloran and Abdanan districts, Ilam Province, Iran. An analysis was made of the species used, parts of the plant employed, preparation methods, administration means, and the ailments treated in relation to pathological groups. A folk botanical survey was carried out from February 2007 to October 2009. The information was collected from 81 persons (60% men and 40% women) in 20 villages. The informants reported data on 122 species, belonging to 49 botanical families, were claimed as medicinal. This work is focused on human medicinal plant uses, which represent 95% of the pharmaceutical uses. The most commonly represented families were Asteraceae (37.5%), Lamiaceae (20.8%), Rosaceae (18.7%), Fabaceae (16.7%) and Apiaceae (14.6%). Some of the uses were found to be new when compared with published literature on ethnomedicine of Iran. The folk knowledge about medicinal plant use is still alive in the studied region, and a number of scarcely reported plant uses has been detected, some of them with promising phytotherapeutical applications. The results of the study reveal that some of species play an important role in primary healthcare system of these tribal communities.

As aculturization and globalization continues, there is an urgent need to carefully record and delineate traditional pharmacopeias so that their true worth is understood and protected and any possible benefits related to their commercial development are equitably distributed. In the past most of these endeavors resulted in a list of plants with their associated uses without providing further explanations as to the extent of this knowledge within the traditional group, or if this knowledge was known elsewhere. This practice tended to generate the notion of finite exclusivity without providing proof that this was actually the case. Moreover, since the talents and methods of those conducting these initial studies varied widely, little effort was made to provide adequate information on how selective processes and preferences as well as modes of collection, preparation and use were achieved. Without these data, the potential of their clinical worth, bioreactive capacities or chemical compositions were often compromised. This frequently led to expending much time, effort and treasure on a pharmacopeia’s evaluation without guidance on how these efforts could be optimized to achieve its best possible medicinal potential. This paper will review how types of dereplications and other techniques are helpful in amplifying this process. doi: 10.4314/ajtcam.v8i5S.12

The people of far-flung rural areas still depend to a large extent upon plants and household remedies for curing veterinary ailments. The folk knowledge of ethnoveterinary medicine and its significance has been identified by the traditional communities through a process of experience over hundreds of years. The paper deals with 34 ailments commonly found in nine different categories of livestock/animals (i e. buffalo, cow, oxen, sheep, goat, horse, mule, dog and cat) and their treatment with 73 medicinal plant species belonging to 70 genera and 45 families that occur in forests as well as close vicinity of the rural settlements. Out of the total population, majority of the people (more than 80%) was found dependent on traditional (herbal) system of treatments practiced by local herbal healers (Pashu Vaidyas), while rest of the people preferred modern (allopathic) system of treatments for curing veterinary ailments. In this study we observed that old aged people have more knowledge and experience particularly in remote areas for curing veterinary ailments. The traditional system of treatment is one of the most important prevailing systems in the area where modern veterinary health care facilities are rare or in very poor conditions.Keywords: Ethnoveterinary uses, Medicinal plants, Veterinary ailments, Livestock, Traditional herbal healers, Alaknanda catchment

In a field survey, conducted in the year, 2011/12, in Imphal valley of Manipur, on the use of herbs as ingredient sources for the production of natural herbal shampoo referred to as “Chinghi”, by Meitei community. The survey revealed that, the therapeutic application of 35 plant species representing 28, genera and 18, families. Tree species contributed immensely, yielding 38%, while herbs 32%, shrubs 27%, and climbing shrubs 3%, respectively being the record of the total number of plants used as ingredient in herbal shampoo preparation. These natural shampoos are used for a wide range of common ailments like anti-ageing of the hair, blackness, shininess and smoothness of the hair. It is prepared from young leaves and tender stalk of shoot of trees or shrubs, or whole plant of the herbs and fresh fruits with local sticky rice water (Oryza sativa subspecies japonica,) locally called “chenggi” after boiling it. Fermented lime peel is also use as a natural herbal shampoo. Interviews and reports from elderly people (uni-sex, between the ages of 30-75), were collected during the survey on the different types of ingredients they have been using, over the years, in “Chinghi” preparation, and benefits they obtained from it. Leaves and whole plant (herb), are the major plant parts used for its preparation at the rate of, 62%, and 14%, respectively. The study shows details of their scientific, common, and local names, including their family, parts used, habit of the plants, and their usefulness.

The present study aims to inventory and analyse the ethnobotanical knowledge about medicinal plants in the Serra de Mariola Natural Park. In respect to traditional uses, 93 species reported by local informants were therapeutic, 27 food, 4 natural dyes and 13 handcrafts. We developed a methodology that allowed the location of individuals or vegetation communities with a specific popular use. We prepared a geographic information system (GIS) that included gender, family, scientific nomenclature and common names in Spanish and Catalan for each species. We also made a classification of 39 medicinal uses from ATC (Anatomical, Therapeutic, Chemical classification system). Labiatae (n=19), Compositae (n=9) and Leguminosae (n=6) were the families most represented among the plants used to different purposes in humans. Species with the most elevated cultural importance index (CI) values were Thymus vulgaris (CI=1.431), Rosmarinus officinalis (CI=1.415), Eryngium campestre (CI=1.325), Verbascum sinuatum (CI=1.106) and Sideritis angustifolia (CI=1.041). Thus, the collected plants with more therapeutic uses were: Lippia triphylla (12), Thymus vulgaris and Allium roseum (9) and Erygium campestre (8). The most repeated ATC uses were: G04 (urological use), D03 (treatment of wounds and ulcers) and R02 (throat diseases). These results were in a geographic map where each point represented an individual of any species. A database was created with the corresponding therapeutic uses. This application is useful for the identification of individuals and the selection of species for specific medicinal properties. In the end, knowledge of these useful plants may be interesting to revive the local economy and in some cases promote their cultivation. This study was supported by the WADI Project (INCO2003-MPC2-015226), financed by the European Commission.

We carried out a study to determine ethno-veterinary knowledge used to treat and prevent livestock diseases in Toteng Village in Ngamiland District, northwestern Botswana. Primary data were collected through simple random sampling of 45 households in Toteng. Respondents were either livestock owners or cattle herders. Respondents were interviewed using a structured questionnaire which had both open and closed-ended questions. Cattle ownership or herdership in Toteng is an inter-generational occupation with people ranging from 15 to 94 years old. Cattle wereacquired either through inheritance, buying, mafisa (reciprocal exchange) system or government scheme. Women in the study area were more involved in livestock farming activities. Eleven livestock diseases were reported to be prevalent in the study area. The top six diseases were tlhako le molomo -foot and mouth disease (FMD), matlho - eye infections, letshololo-diarrhea, madi -pasteurollosis, mokokomalo - aphosphorisis and pholoso- contagious abortion. At least nine medicinal plant species having ethno-veterinary applications were recorded in the study area. Single plants are mostly used rather than a combination of plants. A number of social strategies were mentioned such as ‘go fetola mafudiso’ - to change grazing areas, and ‘go thaa lesaka’ – to ritualistically ‘protect a kraal’ or livestock against evil spells and predators (lions). Although the intervention of conventional veterinary medicine is pervasive in Toteng,and many livestock owners are resorting to it, there is evidence, however, of generalized ethno-veterinary knowledge used to treat and prevent livestock diseases. Local farmers and their herders in Ngamiland are not only knowledgeable and experienced in treating a range of livestock diseases, but also in performing other veterinary tasks such as assisting in births, treating fractures and range management strategies to mitigate particular threats from their local environment. The efficacy of ethno-veterinary knowledge for preventing and treating livestock diseases andrange management strategies identified in this study need to be fully investigated and integrated in veterinary extension services.Key words: Okavango Delta, ethnoveterinary medicine, livestock diseases, indigenous Knowledge, traditional medicinal Plants, ethnodiagnostic skills.

The Pahans and the Telis are two of the smallest indigenous communities in Bangladesh. The Pahans, numbering about 14,000 people are widely scattered in several northern districts of the country, while the Telis are such a small community that nothing has been reported on their numbers and lifestyle. Both tribes are on the verge of disappearance. One each of the Pahan and the Teli community was located after much search in two adjoining villages of Natore district, Bangladesh. Since the tribes were found to still depend on their traditional medicinal practitioners for treatment of ailments, it was the objective of the present study to document their traditional usage of medicinal plants and to evaluate such plants against modern research-based pharmacological activity studies on these plants. Interviews were conducted of the practitioners of the Pahan and Teli community of Natore district with the help of a semi-structured questionnaire and using the guided field-walk method. Plant specimens as pointed out by the practitioners were collected and pressed on the field and identification completed at the Bangladesh National Herbarium. The Pahan tribal practitioners used 13 plants distributed into 9 families for treatment of 14 different ailments. The Teli tribal practitioner used 15 plants divided into 14 families for treatment of 17 different ailments. Eight out of the thirteen plants used by the Pahan tribal practitioner (61.5%) had reported relevant pharmacological activities in the scientific literature, while six out of the fifteen plants used by the Teli tribal practitioners (40%) had such relevant pharmacological activities in accordance with their usage. The medicinal plants used by the Pahans and Telis warrant further scientific studies toward discovery of lead compounds and efficacious drugs and the documentation and protection of the traditional medical knowledge held by these tribes.

The Kanda tribe is one of the lesser known small tribes of Bangladesh with an estimated population of about 1700 people (according to them), and on the verge of extinction as a separate entity. To some extent, they have assimilated with the surrounding mainstream Bengali-speaking population, but they still maintain their cultural practices including traditional medicinal practices, for which they have their own tribal healers. Nothing at all has been documented thus far about their traditional medicinal practices and formulations, which are on the verge of disappearance. The Kanda tribe can be found only in scattered tea gardens of Sreemangal in Sylhet district of Bangladesh; dispersion of the tribe into small separated communities is also contributing to the fast losing of traditional medicinal practices. The objective of the present study was to conduct an ethnomedicinal survey among the traditional healers of the Kanda tribe (in fact, only one such healer was found after extensive searches). Information was collected from the healer with the help of a semi-structured questionnaire and the guided field-walk method. A total of 24 formulations were obtained from the healer containing 34 plants including two plants, which could not be identified. Besides medicinal plants, the Kanda healer also used the body hairs of the Asiatic black bear (Ursus thibetanus) and bats (Pteropus giganteus giganteus) in one of his formulation for treatment of fever with shivering. The ailments treated by the Kanda healer were fairly common ailments like cuts and wounds, skin diseases, helminthiasis, fever, respiratory problems (coughs, asthma), gastrointestinal disorders (stomach pain, constipation, diarrhea), burning sensations during urination, various types of pain (headache, body ache, toothache, ear ache), conjunctivitis, poisonous snake, insect or reptile bites, jaundice, and bone fractures. A number of important drugs in allopathic medicine like quinine, artemisinin, and morphine (to name only a few) have been discovered from observing indigenous medicinal practices. From that view point, the formulations used by the Kanda healer merit scientific studies for their potential in the discovery of cheap and effective new drugs. Scientific validation of the medicinal formulations of the Kanda healer can also be effective for treatment of ailments among this tribe, which does not have or does not want to have any contact with modern medicine.

The current study focussed on documenting the ethnobotanical knowledge of herbal medicines used by the Bapedi traditional healers to treat reproductive ailments in the Limpopo Province, South Africa. Fifty one healers from 17 municipalities covering Capricorn, Sekhukhune and Waterberg districts of the Limpopo Province were interviewed between January and July 2011. Semi-structured interviews, observations and guided field surveys with the healers were employed. Thirty-six medicinal plant species belonging to 35 genera and 20 families were documented. The most used species were Zanthoxylum humile (25.5%), Catha edulis (21.6%), Ozoroa sphaerocarpa (15.7%), Hypoxis hemerocallidea (13.7%), Hypoxis obtusa (11.7%), Gomphocarpus fruticosus subsp. fruticosus and Gymnosporia senegalensis (9.8% each). The dominant growth forms among the reported medicinal plants were herbs (39%), followed by shrubs and trees with 33% and 28%, respectively. The preferred plant parts were roots (63.9%), followed by bark (13.9%), whole plant (11.1%), tubers (8.3%), bulbs (5.6%), fruits, leaves, stems and twigs (2.8% each). The majority of the species were used to treat gender specific reproductive ailments; while a minority were used for treating reproductive ailments of both genders. Twenty-two species (61.1%) are supported by reports of similar uses in other countries or have proven biological activity. This study illustrates that Bapedi traditional healers possess remarkable knowledge on medicinal plants used for treating and managing reproductive ailments.

This study documents the use of ethno-veterinary medicine to treat livestock in Nhema communal area in the Midlands province of Zimbabwe. This study employed oral interviews and detailed discussions with 69 smallholder farmers and 3 traditional healers. The local people use 23 plant species belonging to 16 families as ethno-veterinary remedies. Two plant families were particularly frequent in usage: Fabaceae and Solanaceae, while the most utilized plant species were Aloe chabaudii (UV = 0.69), Aloe greatheadii (UV = 0.65), Adenium multiflorum (UV = 0.63), Vernonia amygdalina (UV = 0.61), Nicotiana tabacum (UV = 56), Solanum lycopersicum (UV = 55), Capsicum annum (UV = 53) and Pouzolzia hypoleuca (UV = 51). Fourteen animal conditions were identified in the surveyed area. The major and most common animal diseases were tick-borne diseases, eye problems, retained afterbirth, fleas, lice and diarrhoea. The majority of ethno-veterinary remedies (78%) were collected from the wild, with respondents mostly using herbs (11 species, 48%), followed by 6 trees (26%), 4 shrubs (17%), and 2 climbers (9%). The most frequently used plant parts were leaves (51%), followed by bark (16%), roots (13%) and fruits (10%). These remedies were mostly administered as decoctions or infusions of single plants. These plants were used not only as alternatives to conventional veterinary drugs but also because in certain diseases they were thought to be more efficacious. In view of many and widespread uses of wild plants as ethnoveterinary remedies, further research into their pharmacological activities may prove worthwhile.

The Santals form the largest tribal community in northern Bangladesh reside primarily in Rajshahi and Rangpur Divisions, where they live in the districts of Rajshahi, Rangpur, Thakurgaon, Dinajpur, and Panchagarh. Although they are fast losing their traditional medicinal practices, they still have their own medicinal practitioners who rely mostly on medicinal plants for treatment of a variety of ailments. The traditional medicinal practices vary quite extensively between the twelve clans of the Santals. The objective of the present study was to conduct an ethnomedicinal survey amongst the Soren clan of the Santal community residing in two villages of Tanor Santal Para in Rajshahi district to collect information on their use of medicinal plants. Interviews were conducted of the two existing Santal traditional medicinal practitioners of the Soren clan with the help of a semi-structured questionnaire and using the guided field-walk method. Plant specimens as pointed out by the practitioners were collected and pressed on the field and identification completed at the Bangladesh National Herbarium. Information on 53 medicinal plants distributed into 32 families was obtained in this survey. Ailments treated by these plants included skin disorders, respiratory tract disorders, gastro-intestinal disorders, sexual dysfunctions, sexually transmitted diseases, diabetes, helminthiasis, pain, urinary problems, filariasis, leprosy, tuberculosis, epilepsy, snake bite, enlarged heart, and paralysis. The medicinal plants used by the Santals merit further scientific studies for some of their formulations are used to treat diseases like diabetes, paralysis, enlarged heart, tuberculosis, and filariasis for which modern medicine has no known cure or medicines have developed resistant vectors.

In Africa, up to 80% of the population relies on herbal concoctions for their primarily health care. In Togo, western Africa, Tem tribe is a population with old knowledge of medicinal plants, however, still very little is known about their medical practices. The present study was conducted to access for the apprehension of adverse effects of traditional remedies by Tem traditional healers (TH). Enquiry was performed by interviews with healers from August to October 2007 in Tchaoudjo prefecture (Togo). The study allowed us to interview 54 TH including 41(75.93%) males and 13(24.07%) females, who cited 102 recipes assumed to have adverse effects. The recipes were used alone to cure several diseases including haemorrhoids (22.55%), female sexual disorders and infertility (21.57%), gastrointestinal disorders (18.63%), and malaria (6.86%). A total of 34 plants belonging to 21 families were cited to be components of the recipes. Euphorbiaceae and Mimosaceae families were the most represented, however, Nauclea latifolia, Khaya senegalensis, Pseudocedrela kotschyi and Xeroderris stuhlmannii were the main components of recipes linked to adverse effects. A total of 20 adverse effects were linked to the administration of theses drugs, and among them; diarrhoea, abdominal pains, polyuria, general weakness and vomiting were the most frequently encountered. These findings were in accordance with several reports of the literature concerning medicinal plants, although they were based on empirical observations. Laboratory screenings are needed to access for the effectiveness as well as the possible toxic effects of the recipes. Keywords: traditional concoctions, medicinal plants, adverse effects, Togo.

Folk medicinal practitioners form the first tier of primary health-care providers to most of the rural population of Bangladesh. They are known locally as Kavirajes and rely almost solely on oral or topical administration of whole plants or plant parts for treatment of various ailments. Also about 2% of the total population of Bangladesh are scattered among more than twenty tribes residing within the country’s borders. The various tribes have their own tribal practitioners, who use medicinal plants for treatment of diseases. The objective of the present survey was to conduct an ethnomedicinal survey among the Kavirajes and tribal practitioners to determine which species of plants belonging to the Verbenaceae family are used by the practitioners. The Verbenaceae family plants are well known for constituents having important bio-active properties. The present survey indicated that 13 species belonging to 8 genera are used by the folk and tribal medicinal practitioners of Bangladesh. A comparison of their folk medicinal uses along with published reports in the scientific literature suggests that the Verbenaceae family plants used in Bangladesh can potentially be important sources of lead compounds or novel drugs for treatment of difficult to cure debilitating diseases like malaria and rheumatoid arthritis.Keywords: Verbenaceae, folk medicine, Bangladesh, medicinal plantsdoi: 10.4314/ajtcam.v8i5S.15

Herbal drugs have been used since ancient times as medicines for the treatment of a wide range of diseases, for both human and livestock. A study conducted in the Lake Victoria Basin Kenya revealed vast knowledge and reliance on traditional medicine as a source of healthcare. The study documented 34 medicinal plant species distributed among 21 botanical families and 34 genera, used in the management of human ailments. The highest numbers of species were from the families Asteraceae and Leguminosae. The most commonly harvested plant parts were leaves (46.51%) and roots (34.88%). The most common growth forms utilised were herbs (40.54%) followed by shrubs (27.03%). The major methods of herbal drug preparation were concoction (31.03%) and decoction (24.14%) administered mainly through oral and dermal routes, (64.29%) and (32.14%) respectively. The use of herbal drugs as mixtures was reported to be a common practice by the herbal practitioners; 57.14% of the preparations were dispensed as mixtures while 42.86% of the preparations composed of single plants. A rich knowledge of medicinal plants was recognized and phytochemical and bioactivity analyses of these herbal plants are recommended to determine their safety and efficacy.Key words: Indigenous knowledge, health care, ethnomedicinedoi: 10.4314/ajtcam.v8i5S.20
