Ashwagandha is a herb with a long history of use in traditional Ayurvedic practice. Today it is sold widely as a dietary supplement, in capsules, powders and teas, and it is often marketed with long lists of benefits. This article separates what studies actually suggest from what is simply claimed.
What the studies suggest
A small number of short studies suggest that ashwagandha may modestly reduce perceived stress in some adults. That is the strongest area of research, and even there the evidence is limited and mixed: the studies are small, they rarely last long, and the products and doses used vary, so results cannot be generalised to everyone or to every supplement on sale.
What it is not
Ashwagandha is not a proven treatment for cancer, anxiety disorders, or any other disease. Treat any product that presents it as a cure or treatment with suspicion. Unlike medicines, supplements are not approved for effectiveness before they are sold, so marketing claims are not evidence that a product works.
Risks and interactions
Ashwagandha can interact with medicines, including thyroid medication, sedatives and immunosuppressants, and it should be avoided during pregnancy. Anyone considering taking it — especially anyone who has a health condition or takes regular medication — should talk to a doctor first. If you have symptoms of anxiety or another condition, a supplement is not a substitute for diagnosis and proper treatment.
