Objective: The objective of this study was to determine if there were any effect of Abelmoschus esculentus on chronic stress induced memory loss. Methods: The Swiss Albino Mice (n=30) were divided into five groups, namely control, chronic stress (90 days), chronic stress and ethanolic extract of Abelmoschus esculentus(200mg/kg body weight), and Chronic stress followed by diazepam (2mg/kg body weight), Chronic stress followed by diazepam (2mg/kg body weight) and ethanolic extract of abelmoschus esculentus (200mg/kg body weight). At the end of the experimental period (90 days), animal blood was collected retro-orbitally to analyze the cortisol, Brain tissue was homogenized, and antioxidants and Acetylcholine esterase level was estimated. Results: The Results of the data indicated that administering stress for a duration of 90 days led to a noticeable decline in spatial learning abilities in mice. Our findings indicate that combination of Abelmoschus esculentus and diazepam showed there was an significant improvement in retaining memory. Conclusion: Study indicated that Abelmoschus esculentus shows promise as a viable treatment option for conditions of stress related memory impairment.

Background: Herbs have long been the basis of medical treatment but the practice of herbalism is not strictly based on evidences gathered using scientific methods. Ashwagandha (Withania somnifera L.) is a traditional medicinal herb used in the treatment of various ailments. Objective: In current study we have evaluated the acetylcholine esterase (AChE) inhibitory and antioxidant potential of Ashwagandha root extract (ARE) in in-vitro and ex-vivo models to give a scientific base to its use in herbal medicine. Methodology: Simplest extraction e.g. maceration method was performed for preparation of extracts using methanol as solvent. Both in vitro and in vivo experimental trial were executed to evaluate the efficacy of root extract. Result and Discussion: ARE substantially scavenged free radicals and effectively prevented protein degradation as well as modification as studied by SDS-PAGE and Western blotting. Pre-treatment with ARE protected rat lymphocytes against H2O2-induced oxidative damage. H2O2 treatment resulted in DNA fragmentation and significantly decreased the activities of key antioxidant enzymes namely superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glucose-6-phosphate dehydrogenase while decreased and increased the content of glutathione and malondialdehyde, respectively. ARE pre-treatment almost reversed these changes indicating its efficiency to suppress hydrogen peroxide-induced oxidative stress. Conclusion: The study provides the scientific basis of pleiotropic functions of Ashwagandha.
