The Claim

In adults with stress and anxiety, Ashwagandha root extract (ARE) at a dose of 600 mg/day for 8 weeks is associated with most commonly reported adverse events: nausea (2.0%), dry mouth (1.4%), and headache (0.2%), all of which are mild to moderate in severity and transient.

In plain English

In adults with stress and anxiety taking 600 mg of Ashwagandha root extract daily for 8 weeks, the most common side effects are nausea in 2% of people, dry mouth in 1.4%, and headache in 0.2%. These side effects are mild to moderate and go away on their own.

See the scientific wording

The most commonly reported adverse events associated with Ashwagandha root extract (ARE) 600 mg/day for 8 weeks in adults with stress and anxiety are nausea (2.0%), dry mouth (1.4%), and headache (0.2%), all of which were mild to moderate in severity and transient.

Why this might work

Ashwagandha root extract contains compounds called withanolides that interact with nerve cell receptors in the brain and gut. These interactions change the balance of the autonomic nervous system, reducing signals that control salivation and digestion. This leads to dry mouth and nausea. The same changes in nerve activity affect blood vessel width in the brain, causing headache.
