About
Ashwagandha is an herb used for thousands of years in traditional Ayurvedic medicine. It’s often called “Indian ginseng” or “winter cherry,” although it’s not actually related to ginseng.
Today it’s mainly marketed as a stress, sleep, and recovery supplement.
Ashwagandha is considered an “adaptogen,” meaning it may help the body adapt to stress. The strongest evidence is around:
- Stress reduction
- Sleep improvement
- Mild anxiety support
Ashwagandha is actually a fairly practical plant to grow if you live in a hot, dry climate. It behaves more like a drought-tolerant medicinal shrub than a delicate herb. The roots are usually harvested after 5-7 months.
