If someone told you that one herb could reduce stress and anxiety, increase energy, improve sleep, quell food cravings, and help you have a better workout and better sex, would it seem too good to be true? Ashwagandha, a star in India’s ancient ayurvedic system of healing, delivers all these benefits and more.
In Sanskrit, its name literally means “smell of a horse,” because of the root’s odor. But taking ashwagandha won’t make you smell bad. Its classic action is that of an adaptogen, meaning it balances the way your body reacts to stress, calming or rejuvenating as needed. And the effects can be far-reaching.
One case history, published in a British medical journal, described a woman whose hair loss was dramatically reduced after she took ashwagandha for a couple of months. It also improved a combination of her underlying health conditions, including disturbances in thyroid, cortisol, insulin, and other hormones. While the herb isn’t usually viewed as a hair-loss remedy, this lady’s experience illustrates how restoring balance can have surprising side benefits.

The Science Behind Ashwagandha
During the past 50 years, numerous scientific articles have been published about ashwagandha, including chemical analyses of its constituents, case histories, and studies of its effects on cell cultures, animals, and people. It calms the central nervous system, reduces inflammation, and has killed cancer cells in lab studies, but its anti-cancer effects have not been proven in humans.
A review of studies following a total of 400 people, by researchers at SUNY Upstate Medical University in Syracuse, N.Y., and the Yale School of Public Health in New Haven, Conn., found that various ashwagandha extracts were effective for relieving anxiety and stress, sometimes as well as anti-anxiety medications, but without harmful drug side effects. Other human trials have used patented ashwagandha extracts, most notably KSM-66 and Sensoril, which can be found as ingredients in many different brands of supplements. These studies have found numerous bonus benefits, in addition to ashwagandha’s stress-relieving prowess.

3. Other Extracts
Many ashwagandha extracts are “standardized,” meaning they have been formulated to contain a specific percentage of key active ingredients found in the plant, most often withanolides. Suggested doses vary, depending upon the formulation. Follow label directions.
4. Pills, Powders, and Liquids
Ashwagandha is available in pills, powders, and liquids. It should not be taken by pregnant women because of its spasmolytic activity on the uterus.
