Background: Alzheimer's disease is a common neurodegenerative disorder in elderly with progressive decline in cognitive functions. This study aimed to investigate the possible memory‐improving effects of Olibanum on patients with Alzheimer's disease. Research Design and Method: This double‐blind, randomized clinical trial was carried out on 72 participants aged 50–75 years. The intervention group (n = 36) received 1.6 g/day of olibanum chewing gum for 18 weeks. The placebo group (n = 36) received chewing gum without olibanum. Neuropsychological assessments were performed at baseline, every 4 weeks, and after 18 weeks of the intervention. Results: There was no significant difference between (MD: 0.84, 95%CI: −1.10 to 2.78, p = 0.392) at baseline. Both groups had linear improvements over time. There was no significant difference between two groups regarding the improvements after the intervention (F = 0.157, p = 0.693). There were no significant differences between the groups for MMSE score (Mini‐Mental State Examination) after the intervention (F = 0.141, p = 0.708). Conclusions: This study revealed that 18 weeks of gum chewing with Olibanum did not change the neuropsychological status. More clinical studies are needed to confirm these findings.

Cisplatin is widely used as one of the most effective anticancer agents in the treatment of some neoplasms. Reproductive toxicity is the most common outcome associated with cisplatin testicular damage. Alternative natural medicines for treating male testicular disorders and infertility have received extensive attention in research. Natural products, medicinal herbs, and their secondary metabolites have been shown as promising agents in the management of testicular damage induced by chemotherapy drugs. This study aimed to review the research related to natural substances that are promising in mitigation of the cisplatin‐induced toxicity in the reproductive system. PubMed and Scopus were searched for studies on various natural products for their potential protective property against reproductive toxicity induced by cisplatin from 2000 to 2020. Eligibility was checked based on selection criteria. Fifty‐nine articles were included in this review. Mainly in animal studies, several natural agents have positively affected cisplatin‐reproductive‐toxicity factors, including reactive oxygen species, inflammatory mediators, DNA damage, and activation of the mitochondrial apoptotic pathway. Most of the natural agents were investigated in short‐term duration and high doses of cisplatin exposure, considering their antioxidant activity against oxidative stress. Considering antioxidant properties, various natural products might be effective for the management of cisplatin reproductive toxicity. However, long‐term recovery of spermatogenesis and management of low‐dose‐cisplatin toxicity should be considered as well as the bioavailability of these agents before and after treatment with cisplatin without affecting its anticancer activity.

Background: Alopecia areata (AA) is a common immune-mediated hair loss disorder. AA has a reported incidence of 0.1-0.2% with a lifetime risk of 1.7%. Histologically, AA is characterized by the accumulation of mononuclear cells around the bulb of the affected hair follicles. Corticosteroids are the most popular drugs for the treatment of this disease. Despite its high prevalence, currently available treatments are mostly unsatisfactory and inefficient for the more chronic and severe types of the AA. Alopecia areata is a well-known disorder in Iranian traditional medicine (ITM). "Da oth-tha , lab" was the term used by ITM scholars to indicate AA. Traditional Iranian physicians believed that the presence of morbid matter in the scalps is the main cause of the disease, which blocks nutrients and causes hair roots to deteriorate. Herbal medicines in the form of topical preparations were applied by ITM scholars for the treatment of AA. This study was performed to determine the most frequent useful herbs for AA as mentioned in ITM., Methods: Seven ITM references such as Canon of Medicine (Avicenna), Alhavi (Razes) Tuhfat ul-Momineen (Mo , men tonekaboni), Makhzan-ul-Adwiah (Aghili), Ikhtiyarat Badi,i (Ansari), Al-abnia An-Haghyegh el-advia (Heravi) and al-jāmi li-mufradāt al-adwiyawa al-aghdhiya (Ibn al-Baitar) were studied for anti-AA medicines. Subsequent to our study, the herbal medicines were listed and scored based on the frequency of their prescriptibility. Moreover, we took the effort to provide the best scientific name for each plant., Results: This study showed that Allium cepa L., Artemisia abrotonon L., Allium sativum L., and Asphodelus ramosus L. were the most frequent herbs mentioned in ITM references for the recovery of AA., Conclusion: These herbs can be introduced as new herbal medicines for clinical research in the field of alopecia areata treatment.
