What Is Ashwagandha?

Also referred to as winter cherry, Indian ginseng, or Vitania sluggard, this evergreen plant grows in Europe, Africa, the Middle East, and India. For thousands of years, it has been used within Ayurvedic medicine. Today, many people use it as a holistic tool to lower stress and encourage better rest.

How Does Ashwagandha Help Sleep?

Research suggests that this herb may improve sleep quality and increase the total amount of time a person spends sleeping. It may also help individuals fall asleep faster and spend less time awake while in bed. These effects can be beneficial for adults regardless of whether they have insomnia.
