Lots of people have trouble sleeping. They may take medications to overcome insomnia but worry about the potential side effects. At this time, anxiety about infection or job insecurity may be keeping lots more people awake. Could the Ayurvedic herb ashwagandha help you fall asleep?

Taking Ashwagandha to Calm Down:

Q. I have been having trouble falling asleep, because I cannot get my mind to stop churning. Although I tried melatonin, it didn’t help. Then I read that an Indian herb called ashwagandha might be helpful. So far, taking it before bedtime seem to calm down and fall asleep within a reasonable amount of time. What should I know about ashwagandha?

A. There are only a few randomized controlled trials of ashwagandha (Withania somnifera) for insomnia. One involving 80 individuals lasted two months and found improved sleep quality and a shorter time to fall asleep (Journal of Ethnopharmacology, Jan. 10, 2021). In additiona, a systematic review of five such studies concluded that this plant product “…has a beneficial effect in improving sleep in adults” (PloS One, Sept. 24, 2021).

Side Effects:

That review did not turn up any serious side effects, but some people find that it can give them headaches, diarrhea, nausea and vomiting. Others have reported elevated liver enzymes and even jaundice and itching indicating liver injury (American Journal of Gastroenterology, Oct. 1, 2021; Journal of the Royal College of Physicians of Edinburgh, Dec. 2021). People with pre-existing liver disease would be wise to avoid taking this supplement. Ashwagandha is a member of the nightshade plant family, and those who cannot tolerate nightshades may react badly to the supplement.

Other Natural Approaches for Insomnia:

Other herbs that have traditionally been used to overcome insomnia include valerian, passionflower, lemon balm and hops. Lavender, when used as aromatherapy, can also help people relax and get to sleep (Medicine, March 5, 2021). You can learn more about all of these in our eGuide to Getting a Good Night’s Sleep.

Could Ashwagandha Help You Sleep Better?

Q. I am high-strung and have had a lifelong struggle with insomnia. That is, until I added ashwagandha to my supplement regimen.

The change was slow and gradual and took a few months, but I started noticing that I could easily fall asleep.

Then, I had the reverse problem. I’m a night person. I love to stay up late after work to watch stuff I’ve taped off the TV, and now I find that I simply can’t stay awake. Every night I fall asleep in my armchair, wake up hours later, amble off to bed and sleep some more.

I could probably sleep ten hours a day if I wanted to (but I don’t). I know it’s the ashwagandha.

What Is Ashwagandha?

A. Ashwagandha is the common name for an Indian herb known officially as Withania somnifera. In the Ayurvedic tradition, practitioners would prescribe it to people needing a tonic, a stimulant or an aphrodisiac (African Journal of Traditional, Complementary and Alternative Medicines, July 3, 2011). They used it for children as well as frail elderly individuals.

That doesn’t sound like a promising candidate to combat insomnia. However, a randomized, double-blind, placebo-controlled trial demonstrated stress-relieving activity for this plant-based compound (Medicine, Sept. 2019). Another eight-week, randomized placebo-controlled study found that people taking ashwagandha (250 mg/day or 600 mg/day) had lower levels of the stress hormone cortisol than those on placebo (Cureus, Dec. 25, 2019). They also reported improved sleep quality. Dr. Tieraona Low Dog, one of the country’s leading experts on the scientific basis of botanical medicine, has described ashwagandha as helpful when a person is “tired but wired.”
