What Is Ashwagandha? 

Ashwagandha (Withania somnifera) is a small shrub native to India and North Africa. Known as a powerful adaptogen, it helps the body adapt to physical and emotional stress.

But it’s not just tradition backing up this herb anymore — there’s now a growing body of clinical research supporting its benefits.
