Ashwagandha (Withania somnifera), is one of the most widely used herbs in traditional medicine systems across various countries, including Indian Traditional Medicine systems. Now, this popular herb has captured the global scientific community’s interest, leading to a surge in the number of scientific studies exploring its use for medicinal purposes. As per the PubMed database, while in 2019, 95 studies on Ashwagandha were listed, in 2024, the number rose to 201—an increase of 111.58%. This upward trend indicates a growing recognition of Ashwagandha’s potential in clinical research and therapeutic applications.
Known for its adaptogenic and therapeutic properties, Ashwagandha is being studied for its potential to reduce stress, improve sleep, boost immunity, and many other health benefits. A small perennial herb with white flowers and orange-red berries thriving in the warmer regions of India, Ashwagandha is commonly referred to as “Indian winter cherry”.
Scientists have discovered that Ashwagandha contains bioactive compounds with diverse pharmacological effects, including anti-inflammatory, antistress, antioxidant, immunomodulatory, hemopoietic, and rejuvenating properties. It has been observed to positively influence the endocrine, cardiopulmonary, and central nervous systems, making it a promising candidate for clinical applications.
A recent systematic review analysing five randomised controlled trials with 400 participants found that Ashwagandha extract significantly improved sleep quality in adults, especially those diagnosed with insomnia. The extract was also noted to enhance mental alertness upon waking and reduce anxiety levels.
Furthermore, several clinical trials suggest that Ashwagandha extracts may help alleviate stress and anxiety. A 2021 systematic review identified seven studies involving 491 adults from India, revealing that Ashwagandha supplementation for 6 to 8 weeks resulted in significant stress and anxiety reduction compared to placebo groups.
Recognising the increasing scientific interest in and around Ashwagandha, the Ministry of Ayush has published a comprehensive safety dossier on the herb to aid scientists and scholars. Also, to address safety-related aspects of the herb, an expert committee was constituted, and its report was published. These publications aim to provide scientifically validated information about Ashwagandha’s safety, efficacy, and therapeutic potential.
With research activity accelerating, Ashwagandha stands at the intersection of traditional wisdom and modern scientific exploration, offering immense promise for human health and well-being. As ongoing studies unlock its full potential, the world may soon witness even greater therapeutic applications of this time-tested herb.
