Therapeutic Potential of <i>Withania somnifera</i> (L.) Dunal (Ashwagandha) in Neuronal Plasticity and Recovery after Stroke

The incidence and mortality of stroke are gradually increasing. In this context, post-stroke neuronal loss and the related long-term complications, along with costly treatment strategies, are significant concerns for healthcare professionals, and effective, convenient, and inexpensive therapeutic modalities are required. Natural and easily accessible herbal remedies may be the optimal option in post-stroke recovery. This narrative review aims to summarize the neuroprotective properties of Withania somnifera (Ashwagandha) and its therapeutic efficacy in neuronal plasticity and recovery after stroke. Original research articles, reviews, and case studies were sourced from databases such as PubMed, Web of Science, Scopus, Google Scholar, Medline, and Embase. Only full articles published in English up to July 2025 were considered. Keywords including W. somnifera, Ashwagandha, stroke, cerebral ischemia, neurodegeneration, neuronal loss, and post-stroke recovery were utilized for the literature search. It has been found that various plant parts of W. somnifera are abundant in bioactive compounds. The neuroprotective effects of W. somnifera are documented in numerous diseases. Nevertheless, W. somnifera is reported to be involved in modulating various biological pathways to mitigate neuroinflammation, apoptosis, and oxidative stress in stroke. W. somnifera promotes cell proliferation and enhances neurogenesis. Preclinical experiments on murine models show the effectiveness of W. somnifera in post-stroke recovery by enhancing neural plasticity and reducing neuronal loss in the infarct area. Furthermore, W. somnifera boosts neurotransmitter levels, improves motor functions, and enhances memory. It also decreases neutrophil infiltration in the infarct region and lessens neuronal loss. Therefore, the application of W. somnifera may prove advantageous in facilitating post-stroke recovery by enhancing neural function. However, well-designed clinical trials are needed to confirm the efficacy of W. somnifera in post-stroke recovery in humans.
