Neurodegenerative diseases and Withania somnifera (L.): An update
Abstract
Ethnopharmacological relevance Withania somnifera (L.) Dunal also known as 'Ashwaghanda' in Sanskrit and as 'Indian Winter Cherry' in english. is an important medicinal herb in India. It is widely used in Indian systems of medicine as an adaptogen, nerve tonic, anti-stress, memory enhancer and against cognitive deficits, insomnia, anxiety, infectious diseases, infertility, rheumatoid arthritis and gout over thousands of years. Its formulations are mainly used in Unani and Ayurvedic system of medicine. It is a remarkable centuries old herbal Rasayana used to treat neuronal ailments and is known as ''Sattvic Kapha Rasayana.Aim of the study To review neuroprotective properties of Withania somnifera (L.)extract as well as its active constituents in neurodegenerative diseases and other neurological ailments.Materials and methods The sources of information used in present article include Indian system of Medicine reports on the use of natural products, Medicinal books, research articles and scientific databases like PubMed, Google Scholar, Web of Science, Science-Direct, SciFinder, ACS Publications and Wiley Online Library.Results Research reports based largely on preclinical studies as well as few clinical trials have highlighted the neuroprotective role of Ashwagandha against many neurodegenerative diseases including Alzheimer's, Huntington's and Parkinson's disease. The protective effects of Ashwagandha were accomplished by restoring mitochondrial and endothelial function, mitigation of apoptosis, inflammation and oxidative stress mechanisms.Conclusion In this review, we recapitulated neuroprotective properties of Ashwagandha extracts and/or its major constituents and discussed their mechanisms of action and potential therapeutic applications. The pre-clinical as well as clinical studies suggest the use of Withania somnifera (L.) against neurodegenerative disease. However, extensive studies are warranted to validate the use of extract or its single constituents for its clinical use.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
