Ashwagandha (Withania somnifera), sometimes called Indian ginseng, is a root used in Ayurvedic medicine for over 3,000 years. Its name translates roughly to “smell of the horse,” a nod to its traditional reputation for building strength and vitality. It’s one of the more studied adaptogens on the market today, used for stress management and general resilience.
What the research actually shows
Ashwagandha has a genuine, if still-developing, evidence base. Several small clinical trials have found it may help lower cortisol levels and reduce self-reported stress and anxiety compared to placebo, and some studies point to modest improvements in sleep quality. The effect sizes and quality vary between studies, and larger, longer-term research is still ongoing — so it’s fair to call it promising, not proven beyond doubt. Be wary of any source citing precise percentages without a named, checkable study behind them.

Things to know before trying it
Ashwagandha is generally well tolerated, but it’s not risk-free for everyone. Possible side effects include digestive upset and drowsiness. It can interact with thyroid medication, sedatives, and immunosuppressants, and it isn’t recommended during pregnancy or while breastfeeding. Talk to a healthcare provider before starting it, especially if you’re on any regular medication — and start with a lower dose to see how your body responds.
