Recently, research on using plant-derived drugs as anticancer agents has been greatly developed. Terminalia chebula (T. chebula) Retz., the mature fruit of T. chebula, contains active ingredients that have antioxidant, antimicrobial, and antitumor effects. Because traditional Chinese medicine components have unstable physical and chemical properties, such as poor solubility, fast decomposition, and high irritation, drug nanocarriers that effectively increase their solubility and reduce irritation are desirable. Additionally, T. chebula fruit can inhibit tyrosinase activity. This study aimed to determine whether T. chebula nanostructured lipid carriers can regulate the proliferation and apoptosis of melanoma cells by inhibiting tyrosinase activity. Tyrosinase activity in drug-treated melanoma cells was detected by MTT and DOPA oxidation assays, and cell proliferation rate was observed. Western blot (MTT) was used to detect the activity of apoptotic factors, and flow cytometry was used to determine the apoptotic rate. The results showed that tyrosinase activity and cell proliferation rate decreased with increasing drug concentration in cultured cells. Furthermore, the inhibitory effect was concentration-dependent. Additionally, cells cultured with a high concentration of T. chebula nanostructured lipid carriers could activate apoptotic factors and increase cell apoptosis. Thus, this study showed that T. chebula fruit nanostructured lipid carriers could inhibit the proliferation of melanoma cells and increase apoptosis by inhibiting tyrosinase activity, demonstrating a new plant-derived drug for melanoma treatment.

Cancer chemotherapies may result in resistance, and therefore, contemporary treatments including natural products may find an increasing consideration. As per Persian medicine (PM), many natural products have been used for malignant and chronic diseases. Triphala, with a combination of Terminalia chebula Retz., Terminalia bellirica Retz., Phyllanthus emblica L., and honey, is a multi-ingredient traditional formulation attributed to anticancer activities in PM. This study is aimed at evaluating the cytotoxic activity of this preparation on HepG2, the human liver cancer cell line. Hydroalcoholic extracts were prepared from the formulation and its components. Compared with the control and Cisplatin, the extracts were tested using MTT assay at different concentrations. All concentrations of the preparation, as well as Cisplatin, were effective significantly against HepG2 cells. All extract preparations at multiple concentrations were significantly effective as evidenced by MTT assay when compared to the control group. The IC50 level for Triphala extract was 77.63 ± 4.3 μ g / ml . Based on the results, Triphala and its components have cytotoxic activity on the HepG2 cancer cell line and they can reduce the survival rate significantly.

In the present study, the antibacterial activity and in vivo acute toxicity of five different extracts was analyzed. The Minimum Inhibitory Concentration and antibacterial activity of five different extracts, including Terminalia chebula, Camellia sinensis, Glycyrrhiza glabra, Vitis vinifera, and Terminalia arjuna, against three different bacterial species, namely, Streptococcus pyogenes, Haemophilus influenza, and Staphylococcus aureus was analyzed by broth dilution method and agar well diffusion method, respectively. The in vivo acute oral toxicity was analyzed by using Wistar rats. The antibacterial activity of different extracts was calculated by analyzing the zone of inhibition, and the maximum zone of 22 mm and minimum zone of 10 mm were observed against the different upper respiratory infections causing bacteria. The lowest MIC (0.8 mg/ml) found was of Camellia sinensis against the Streptococcus pyogenes and Staphylococcus aureus. No sign of toxicity and mortality was observed during the 14 days of study. The in vitro results of the tested extracts indicate that they possessed antibacterial activity and were found non-toxic. So, it can be used as an alternative for the treatment of upper respiratory infection-causing bacteria.

The objective of this study was to evaluate protective effects of hydroethanolic extracts of Terminalia chebula and Thymbra spicata on viability, lipid peroxidation (LPO) and DNA integrity of ram fresh semen under normal and oxidative stress (OS) conditions. Antioxidant activities of different concentrations of Terminalia chebula and Thymbra spicata extracts were evaluated with DPPH assay. Semen samples were taken from three fertile adult rams. After diluting semen with Tris‐base extender, different concentrations of Terminalia chebula and Thymbra spicata (30, 300, and 3000 μg/ml) extracts were used under normal and induced OS conditions. The group not receiving any supplements was considered as control group. A total of 50 μM hydrogen peroxide was used to induce OS. MTT solution was added to each of treatment groups which were kept in an incubator at 37°C for 2 h. After incubation, readings were obtained by ELISA reader. DNA integrity and LPO were determined with acridine orange (AO) staining and malondialdehyde (MDA) assay. Higher concentrations of Terminalia chebula and Thymbra spicata extracts preserved viability and DNA integrity while reducing MDA concentrations compared to other treatment groups. Also, under induced OS, higher concentrations of both extracts reduced detrimental effects of H2O2. In conclusion, it seems that addition of Terminalia chebula and Thymbra spicata extracts can reduce induced OS in spermatozoa., This study was to evaluate the protective effects of the hydroethanolic extracts of Terminalia chebula and Thymbra spicata on viability, lipid peroxidation, and DNA integrity of ram fresh semen under normal and oxidative stress conditions

Objective: Dental caries is an infectious disease in which S. mutans plays a key role. Haphazard and irrational use of antibiotics leads to antibiotic resistance and fatal diarrhoeal diseases in children. Antimicrobial potency of Terminalia chebula and Piper nigrum extracts against several bacterial strains have been documented. The aims of this study were to assess and compare the antimicrobial activities of T. chebula and P. nigrum extracts against S. mutans with Ciprofloxacin as the positive control. Materials and Methods: For this purpose, S. mutans was isolated from plaque samples of people with active caries lesions. Antimicrobial potency of both T. chebula and P.nigrum were tested using agar well diffusion method. Results: All the tested extracts showed antibacterial activity against S. mutans bacteria. Regarding the two tested herbs extracts, a higher antimicrobial activity was shown by the methanol extract of T. chebula with a mean diameter of inhibition zone was 26.75mm and a minimum inhibitory concentration (MIC) at 25mg /ml concentration followed by acetonic extract. Conclusion: These findings confirm the Antimicrobial potency of T. chebula which can be used as an alternative antibiotic and/or in combination with allopathic antibiotics to prevent the antibiotic resistance.

Background: Dental caries is mainly composed of various cellular components and is deposited around the tooth surface and gums, causing a number of periodontal diseases. Streptococcus mutans is commonly found in the human oral cavity and is a significant contributor to tooth decay. The use of antibacterial ingredients in oral hygiene products has demonstrated usefulness in the management of dental caries. This study investigated the anticaries effect of the ethanol extract of Terminalia chebula (EETC) against S. mutans and their cytotoxicity to gingival epithelial cells. Methods: The EETC was prepared from T. chebula fruit using ethanol extraction. Disk diffusion, minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and colony forming unit (CFU) were analyzed to investigate the antimicrobial activity of the EETC. Glucan formation was measured using the filtrate of the bacterial culture medium and sucrose. Gene expression was analyzed using reverse transcription-polymerase chain reaction (RT-PCR). Cytotoxicity was analyzed via the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay. Results: The antibacterial activity of the EETC was explored using disc diffusion and CFU measurements. The MIC and MBC of the EETC were 10 and 20 μg/ml, respectively. EETC treatment decreased insoluble glucan formation by S. mutans enzymes and also resulted in reduced glycosyltransferase B (gtf B), gtf C, gtf D, and fructosyltransferase (ftf), expressions on RT-PCR. In addition, at effective antibacterial concentrations, EETC treatment was not cytotoxic to gingival epithelial cells. Conclusion: These results demonstrate that the EETC is an effective anticaries ingredient with low cytotoxicity to gingival epithelial cells. The EETC may be useful in antibacterial oral hygiene products for the management of dental caries.

Da’ al-Sadaf (Plaque psoriasis) is the most common form of the psoriasis in which raised, red patches covered with a silvery white buildup of dead skin cells. These patches or plaques most often show up on the scalp, knees, elbows and lower back. Sometimes it is itchy and painful and, may cracked and bleed. Unani oral and topical medicines along with Narrow Band Ultra-Violet (NB-UV-B) therapy is used here for treatment. Unani coded formulation UNIM-401 containing Barg Shahtra (Fumaria parviflora Linn.), Chiraita Talkh (Swertia chirata Buch.), Babchi (Psoralea corylifolia Linn.) and Haleela Siyah (Terminalia chebula Retz.) in the ratio of 5:5:5:2, in a dose of 2 capsules (500 mg each) orally with lukewarm water twice a day in empty stomach for a period of three months are given and Soranil ointment mixed with clarified butter in 1:1 ratio was applied on the affected part and exposed to the NB-UVB light for 10 minutes. Plaques of psoriasis getting shade off after one month of treatment and almost disappeared from the site of lesion after three months. The skin of patient almost become normal. It may be concluded that Unani drugs (oral & topical) along with NB-UVB therapy is beneficial for controlling and treating plaque psoriasis.

The work sought to investigate, using response surface analysis, the synergistic antioxidant activity among four plants—Terminalia chebula Retz. var. chebula, Terminalia arjuna Wight and Arn., Terminalia bellirica (Gaertn.) Roxb., and Phyllanthus emblica L.—which are comprised in the Chatuphalathika recipe. The response surface analysis of the four-component simplex lattice design was performed using the combination index method. The mass ratio of the four plants was varied. The total phenolic content, antioxidant activity based on the half-maximal inhibitory concentration (IC50) from 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays were monitored and used to calculate the combination index value. Results showed that the total phenolic content was high and the IC50 values from DPPH and FRAP assays were low when T. chebula, T. arjuna, and T. bellirica were used without P. emblica. Synergistic antioxidant activity was also observed among them. The mixture of T. chebula, T. arjuna, and T. bellirica without P. emblica gave better synergistic antioxidant activity than when P. emblica was incorporated. The data from this work could be used to select the suitable mass ratio of the plants for the preparation of the supplementary health products in further work.

Background and aim Herbal medicines are used to treat a broad number of maladies. However, the pharmacological profile of most remedies is poorly understood. We investigated the effect of herbal remedies from kampo, traditional Chinese medicine (TCM) and other phytotherapies on human two-pore domain potassium channels (KCNK channels; TREK-1, TASK-1 and TASK-3) as well as the human TRPV1 channel. KCNK channels are responsible for the background potassium current of excitable cells, thus essential for the maintenance of the resting membrane potential. Hence, modulators of KCNK channels are of medical significance, e.g. for the treatment of sleep disorders and pain. The transient receptor potential channel TRPV1 is a pain detector for noxious heat. Agonists of this receptor are still used for the treatment of pain in ectopic applications. Experimental procedure We evaluated the effect of 158 herbal remedies on these channels in a heterologous expression system (Xenopus laevis oocytes) using the two-electrode voltage-clamp technique with the aim of increasing the comprehension of their pharmacological profile. Results and conclusion Some remedies with modulating effects were identified such as Angelica pubescens (radix), which inhibit TASK-1 and TASK-3 channels. Furthermore, the modulatory effects of the most effective remedies on the two TASK family members TASK-1 and TASK-3 correlate positively, reflecting their close relation. For the TRPV1 channel Terminalia chebula and Alchemilla xanthochlora were identified as potentiators. This study identifies a variety of herbal remedies as modulators of human K2P and TRPV1 channels and gives new insights into the pharmacological profile of these herbal remedies., Graphical abstract Image 1, Highlights • Effect of kampo and TCM herbs on human two-pore domain potassium and TRP channels. • Effect of 158 herbal remedies on heterologously expressed ion channels. • Angelica pubescens (radix) extracts inhibit KCNK3 and KCNK9 channels. • Modulatory effects of effective remedies on KCNK3 and KCNK9 correlate positively. • Terminalia chebula and Alchemilla xanthochlora are TRPV1 potentiators.

The COVID-19 disease caused by the SARS-CoV-2 has emerged as a worldwide pandemic and caused huge damage to the lives and economy of more than hundred countries. As on May 10, 2020, more than 4,153,300 people stand infected from the virus due to an unprecedented rate of transmission and 282,700 have lost their lives because of the disease. In this context, medicinal plants may provide a way to treat the disease by targeting specific essential proteins of the virus. We screened about 51 medicinal plants and found that Tea (Camellia sinensis) and Haritaki (Terminalia chebula) has potential against SARS-COV-2 3CLpro , with an IC50 for Green Tea as 8.9 ± 0.5 µg/ml and Haritaki 8.8 ± 0.5 µg/ml. The in-silico studies suggested that Tea component Thearubigins binds to the cysteine 145 of protease active site and could be a pharmacoactive molecule. We predict that the inhibition in protease activity may be able to halt the SARS-CoV-2 replication cycle and therefore, we propose Green Tea, Black Tea, and Haritaki plant extracts as potential therapeutic candidates for SARS-CoV-2 infection. Further investigation on role of bioactive constituents of extracts is needed to establish the molecular basis of inhibition and towards expedited drug discovery.

Endothelial dysfunction is a crucial complication in type 2 diabetic patients, related to cardiovascular risk. Terminalia chebula (TC), a traditional ayurvedic herb, is known for its antioxidant and antihyperlipidemic activity. A prospective, randomized, double-blind, placebo-controlled clinical study was undertaken to evaluate the effects of an aqueous extract of T. chebula 250 and 500 mg versus placebo on endothelial dysfunction and biomarkers of oxidative stress in type 2 diabetic patients. A total of 60 eligible patients were randomized to receive either T. chebula 250 mg, T. chebula 500 mg, or placebo twice daily for 12 weeks. The subjects were assessed based on the endothelial function, the levels of nitric oxide, malondialdehyde, glutathione, high sensitivity C-reactive protein, glycosylated hemoglobin, and lipid profile at baseline and after 12 weeks of treatment. Treatment with T. chebula 250 mg and T. chebula 500 mg for 12 weeks significantly improved the endothelial function (reflection index) compared to placebo (absolute changes: - T. chebula 250: -2.55 ± 1.82% vs. T. chebula 500: -5.21 ± 2.41% vs. placebo: 1.40 ± 2.11%). Other cardiovascular risk indicators were also significantly ameliorated in the treatment groups compared to placebo. In conclusion, T. chebula (especially, 500 mg BID dose) significantly minimized the cardiovascular risk factors in patients with type 2 diabetes compared to placebo.

Sleep deprivation (SD) can induce cognitive and memory impairments. This impairment is in part due to oxidative stress damage in the hippocampus region of the brain. Corilagin (CL), a polyphenol belonging to the tannin family and extracted from Terminalia chebula and Phyllanthus emblica, shows strong antioxidant and neuroprotective effects. NF-E2-related factor (Nrf2)/heme oxygenase-1 (HO-1) and NADPH oxidase (NOX) are critical targets involved in cellular defense mechanisms against oxidative injury. Thus, we hypothesized that CL could be a preventive treatment for SD-induced memory impairments by inhibiting NOX2 and activating Nrf2. The results from behavioral tests showed that administration of CL resulted in significantly better performance compared to the SD mice. CL significantly normalized the elevated MDA level and the reduced activity of GPx and SOD (P

Terminalia chebula Retizus fruit contains phytochemicals like phenols including flavonoids which are responsible for hypocholesterolaemic, anti-inflammatory, anti-allergic, antimicrobial, antioxidative properties. In the present study the effect of drying temperatures (40–80 °C) on drying kinetics during convective drying of deseeded T. chebula fruit was investigated. The data from the drying experiments were fitted into seven different drying models and the best model was selected by comparing the coefficient of determination (R2) and root mean square error (RMSE). Degradation kinetics for vitamin C, antioxidant activity (DPPH radical scavenging activity), total phenol content (TPC) and total flavonoid content (TFC) was evaluated at 60, 70 and 80 °C. Change in colour at these temperatures were also observed. From the results it was found that an increase in the temperature increased the drying rate and the drying time was reduced, and the mathematical model for drying which best fitted the experimental data was ‘Approximation of diffusion’ model. The degradation of the phytochemicals and change in colour followed the first order kinetics. The rate at which vitamin C degraded was found to be higher than the other components for all temperatures. The rate of change in total colour difference (ΔE*) decreased with increasing temperature.

Background Dental caries is an oral disease which is infectious in nature associated with various pathogenic microorganisms and is prevalent across the world. Aim To evaluate and compare the anticariogenic properties of the different plant extracts against various cariogenic microorganisms. Materials and methods In phase I, the anticariogenic efficacy of four different herbal extracts, namely Ocimum sanctum (Tulsi), Terminalia chebula (Harad), Tinospora cordifolia (Guduchi), and Glycyrrhiza glabra (Licorice), was evaluated against two strains of bacteria viz. Streptococcus mutans and Lactobacillus acidophilus. In the second phase of the study, the overall decay depth was compared. Results In phase I, zone of inhibition was significantly higher in G. glabra (Licorice) followed the descending order by O. sanctum (Tulsi), T. c hebula (Harad), and T. cordifolia (Guduchi), respectively. In the second phase, it was found that the decay depth was significantly higher in T. cordifolia (Guduchi) followed the descending order by T. chebula (Harad), O. sanctum (Tulsi), and G. glabra (Licorice), respectively. Conclusion Glycyrrhiza glabra (Licorice) extract had potent antibacterial efficacy against S. mutans and L. acidophilus. Clinical significance Synthetic drugs have many adverse effects, so more attention has been paid to natural remedies because they are safe and effective. Today, the main interest is shifted toward the drugs which is derived from plants, which has led to the screening of many herbal plants for their potential antimicrobial activity and the same can be used clinically as an alternative of synthetic drugs used in dentistry.

Traditional Triphala (three fruits), consisting of Phyllanthus emblica, Terminalia chebula, and Terminalia bellirica, presents a broad range of biological activities. However, its ability to inhibit dengue virus (DENV) infection has not been reported yet. Herein, the authors investigated the efficiency of three different Triphala formulations and its individual extract constituents to inhibit DENV infection. Treatment with T. bellirica extract or Triphala formulated with a high ratio of T. bellirica extract showed remarkable efficiency in significantly lowering DENV infection in Vero cells. Their effects were further studied in Huh7 cells, to address its potential ability in human cells. Treatment with 100 μg/mL of T. bellirica extract or Triphala resulted in an approximate 3000-fold or 1000-fold lowering of virus production, respectively. Furthermore, the treatment diminished IL-6 and CXCL-10 expressions, which are the hallmark of the cytokine storm phenomenon in DENV infection. The HPLC profiling demonstrated gallic acid as a major compound, the treatment by which showed its ability to effectively inhibit DENV infection after virus entry. Molecular docking demonstrated that gallic acid was able to interact with DENV NS5 protein, which could be one of Triphala’s antiviral mechanism. This study offers Triphala formulation and its ingredient, T. bellirica extract, as a natural based pharmaceutical to be used in DENV infection treatment.

Background: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the super-spreading virus, has claimed hundreds of thousands of lives worldwide. Objectives: This study aimed to evaluate the effectiveness of the novel suggested herbal compound, formulated as compressed tablets, in reducing the length of hospital stay (LoS), intensive care unit (ICU) admission, and mortality in confirmed COVID-19 cases. Methods: Following an open-label, single-blind randomized clinical trial design, a total of 200 patients aged 18-65 admitted to Imam Reza hospital in Tabriz, northwest of Iran, were randomized to intervention and control groups in a 1:1 ratio, i.e., 100 subjects in each group. The former received standard treatment along with the compressed herbal tablets, and the latter only received the standard treatment. Adverse reactions incidence within 180 days after the beginning of the intervention was set as the primary safety endpoint. The most important and active ingredients of the tablets were Terminalia chebula, Glycyrrhiza glabra, Anacyclus pyrethrum, Senna alexandrina, Ferrula asafoetida, Pistacia lentiscus, Zizyphus jujuba, Crocus sativus, Echinacea angustifolia, and Hyssopus officinalis. This trial is registered at the Iranian Registry of Clinical Trials (code: IRCT20200522047545N1). Results: Those in the intervention arm had significantly lower rates of LoS (7.38 vs. 9.45, P = 0.030), ICU admission (6 out of 100 vs. 32 out of 100, P = 0.000), and mortality (1 vs. 19 out of 100, P = 0.000). Conclusions: Our observations suggest that adequate improvement is provided by the prepared herbal compound along with substantial savings in hospitalization hoteling costs. While further multi-center studies with a larger sample size are needed to extend our knowledge regarding the effect of this new option, these novel clinical data may well provide a new alternative for the management of COVID-19 disease.

In herbal medicine, crude plant extracts in the form of herbal extracts are used by the population for the treatment of diseases, including infectious diseases. Several hundred genera of plants are used as vital sources for potent and powerful drugs. The objective of present study were to determine the antimicrobial effect of some natural products of herbal and spice extracts; and compare the antimicrobial activity these aqueous and ethanolic extract test products with reference to MIC and MBC. The current study was carried out on five selected fresh samples from various conditions. Using the agar well and disc diffusion methods, the antimicrobial effects of Tripfala, Java plum, Cinnamon, Henna, and Cumin against both gram-positive and gram-negative bacteria were investigated. The zone of inhibition or antimicrobial activity of aqueous extracts of selected sample extracts was greater than that of ethanolic extracts. Among the five selected microbes, Klebsiella sp. had the lowest sensitivities to Tripfala and Java plum extracts, whereas these aqueous and ethanolic extracts had strong antimicrobial activity against four other microbes. The MIC values for all of the natural products ranged from 12.5-25.0 ug/ml, while the MBC values ranged from 25- 100.0ug/ml. During the four-month preservation of prepared discs of these natural plant products, no change in antimicrobial activity was observed. This research suggests that Tripfala and Java Plum have the potential to be used as a source of new broad-spectrum oral antibiotics.

Schizophrenia, as a chronic and disabling mental disorder, causes a wide range of symptoms, including cognitive impairments, positive, negative, and mood symptoms. There are no effective treatments for cognitive symptoms. Black myrobalan (Terminalia chebula Retz.), a medicinal plant of the Combretaceae family, exerts antioxidant, antiacetylcholinesterase, and anti-inflammatory effects. These effects can lessen the symptoms of schizophrenia. So, this study was conducted to evaluate black myrobalan's impact on cognitive impairments and negative/positive symptoms in patients with chronic schizophrenia. This was a randomized, double-blind, placebo-controlled clinical trial in which participants were divided into treatment and placebo groups. They received six 500 mg capsules of black myrobalan or placebo in two divided doses for 4 weeks. Patients' cognitive impairments, positive, negative, depression/anxiety, and excitement/activity symptoms were assessed using the Screen for Cognitive Impairments in Psychiatry (SCIP) and the relevant subscales of the Positive and Negative Syndrome Scale (PANSS) pretreatment and 4 weeks after treatment. Cognitive impairments (SCIP) (p value .004), negative symptoms (PANSS subscale) (p value .017), and excitement/activity (PANSS subscale) (p value .003) were significantly improved in the black myrobalan group compared with the control group after 4 weeks. No serious adverse effects were reported. Black myrobalan could improve cognitive impairments, negative and excitement/activity symptoms in chronic schizophrenic patients.

Wheat, barley or wheat + barley and herbs (Terminalia chebula, Terminalia bellerica and Emblica officinalis) based low-glycemic-index (low-GI) foods were developed and studied α-amylase, α-glucosidase and DPP-IV inhibition property in vitro and in the streptozotocin-induced diabetic rats. The GI of products ranged from 47 to 53 than control white bread (GI = 95). Total phenolic (20.1 ± 1 mg gallic acid/g dry wt.) and flavonoids (15.2 ± 1 mg quercetin/g dry wt.) were higher in wheat + barley than barley (17.2 ± 1; 13.6 ± 2) and wheat (16.9 ± 1; 14.9 ± 2) products. The in vitro α-amylase (4–10%), α-glucosidase (5–17%) and DPP-IV (3–26%) inhibition (IC(50)) of methanol extracts were higher than the aqueous extracts. The fasting blood glucose (50.85, 33.22 and 24.52%) and oral glucose tolerance (AUC = 32.1, 36.04, and 27.73%) was lower in barley, wheat, and wheat + barley fed diabetic groups than diabetic control group (1571.5 ± 13.5 mg/dL/120 min). Feeding wheat, barley, and W + B foods for 60 days inhibited the intestinal α-amylase (1.2, 1.1 and 1.5-folds), α-glucosidase (1.3, 1.2 and 1.7-folds) and DPP-IV (1.6, 1.5 and 2.1-folds) activity compared to diabetic control. Low-GI foods lower the systemic glucose level, inhibit the glycolytic enzymes and DPP-IV activity and hence desirable for diabetes management.

Highlights • The effects of dietary supplementation of three Bangladeshi traditional medicinal plants (TMP) were evaluated on growth performance, digestibility of nutrients, hematological indices, immune index and antioxidant status in post-weaned bull calves. • Feed supplementation with TMP enhanced health indices such as augmentation of monocyte, platelet percentage, IgG and lymphocyte proliferation whereas a reduction of IGF was recorded. • An elevated level of TNF-α, total antioxidant and glutathione peroxidase activities were found in calves treated with medicinal herbs., Traditional medicinal plants (TMP) are considered valuable alternatives to hazardous synthetic chemical utilized as animal growth promoters. This study aimed to evaluate effects of dietary supplementation of seed and leaf powder (75:25) of three Bangladeshi TMP viz. Emblica officinalis Gaertn., Terminalia bellirica Gaertn. Roxb., and Terminalia chebula Retz. on growth performance, digestibility of nutrients, hematological indices, immune index and antioxidant status in post-weaned bull calves. Dietary treatments: TMP1 (basal diet = green grass + concentrate), TMP2 (basal diet + 0.5% mixture of seed and leaf (75:25) of E. officinalis Gaertn.), TMP3 (basal diet + 0.5% mixture of seed and leaf (75:25) of T. bellirica Gaertn. Roxb.), and TMP4 (basal diet + 0.5% mixture of seed and leaf (75:25) of T. chebula Retz.). Supplementation of TMP significantly (p

Silver nanocolloids are synthesized using the extract of Triphala which is a compound formulation consisting of three different mixtures of plants (Emblica officinalis, Terminalia belerica, Terminalia chebula) (Tp). Formulating the Triphala extracts into silver nanocolloids (TpAgNc) can cure harmful diseases and can bring remarkable changes in the medicinal field because of the synergistic effect of silver and extract. Biophysical characterization of TpAgNc was performed using UV–visible spectroscopy, FT-IR, FESEM, EDAX, Particle size distribution and zeta potential. Antimicrobial activity of TpAgNc was evaluated against biofilm-forming clinical strains of Klebsiella pneumoniae. minimum susceptibility concentration, minimum bactericidal concentration, growth and biofilm inhibition assays were performed. TpAgNc showed potential antibacterial and antibiofilm activity against biofilm-forming K. pneumoniae. Further, the expression of antibiotic-resistant gene CTXM-15 and Amp C was analysed in TpAgNc treated and control. The expressions of both CTXM-15 and Amp C were downregulated in TpAgNc-treated pathogenic K. pneumonia when compared to control. Our results suggest that there is a strong correlation between biofilm formation, virulence and CTXM-15 expression in clinical strains of K. pneumoniae. The present research work revealed that TpAgNc can be incorporated in different formulations to control pathogenic bacteria causing life-threatening infections in humans and animals.

Background The present study was aimed to evaluate the molecular level anticaries effect of different medicinal plants against Streptococcus mutans (S.mutans) glucosyltransferases (gtf). Methods A total of six natural sources named as Terminalia chebula (T.chebula), Psidium guajava (P.guajava), Azadirachta indica (A.indica) and Pongamia pinnata (P.pinnata); two essential oils, clove (Syzygium aromaticum) and peppermint oil (Mentha piperita) were selected as test samples. Hydroalcoholic plant extracts and essential oils were examined for their inhibitory potential on gtf isolated from S.mutans. Polyherbal mouth wash was prepared and its effect on gtf activity was compared with commercial chlorhexidine mouth wash (5%w/v). Enzyme kinetic study was carried out in order to explore the molecular mechanism of enzyme action. Results Out of six natural sources tested, A.indica has shown maximum inhibitory effect of 91.647% on gtf and T.chebula has shown IC50 of 1.091 mg/ml which is significant when compared to standard chlorhexidine. From the final result of kinetic analysis it was found that T.chebula, P.guajava and P.pinnata have show uncompetitive inhibition where as A.indica has shown non-competitive inhibition. Surprisingly, both essential oils have shown allosteric inhibition (sigmoidal response). The polyherbal moutwash has shown significant inhibitory potential on gtf (95.936%) when compared to commercial chlorhexidine mouthwash (p

Mercury generates free radicals and oxidative stress which are associated with renal injury. Tribulus terrestris (TT), Boerhavia diffusa (BD), and Terminalia chebula (TC) have anti-inflammatory and antioxidant properties. Hydroalcoholic extract of combination of TT, BD and TC were evaluated against mercuric chloride induced nephrotoxicity. Rats (n = 6) were treated with combination of TT, BD and TC in three different doses (198, 300 and 600 mg/kg) of equal ratio of each drug and Combination per se. Drugs were administered orally for period of 7 days. Nephrotoxicity was induced by single dose of mercuric chloride (5 mg/kg, i.p.) on fifth day. Combination of above drugs at all three doses significantly (p

The fruit of Terminalia chebula Retz., or Tibet Olive, is widely used as a food supplement in China. It possesses some natural antimicrobial properties; however, its chemical composition and antivirulence effects have not been identified. In this work, 29 compounds were identified from the peel of T. chebula fruit by ultra-high-performance liquid chromatography-tandem quadrupole time-of-flight mass spectrometry. Both the extract of T. chebula and its phenolic acid, corilagin, showed antivirulent activity against Staphylococcus aureus. Specifically, they inhibited biofilm formation. The half maximal inhibitory concentration was 0.13 and 3.18 µg/mL for the extract and corilagin, respectively, whereas for α-hemolysin secretion, the respective concentrations were 30 and 10 µg/mL. Its mechanism of action may be due to reducing the transcription of genes related to quorum sensing. These genes included staphylococcal accessory regulator A, intercellular adhesion accessory gene regulator A, and RNAIII. These findings provide evidence that this food supplement could be an effective antivirulent with corilagin as its active ingredient. PRACTICAL APPLICATION: Corilagin from the fruit of Terminalia chebula Retz. may be used as an antibacterial for its antivirulent activity against Staphylococcus aureus.
