Ashwagandha, is an herb used in Ayurvedic medicine. It grows in dry areas of India, the Middle East and parts of Africa (1). It is an adaptogen, helping the body to naturally adapt to stress and normalize bodily processes.
As an adaptogenic herb ashwagandha works by increasing general vitality and resistance, and strengthening the body's system. It is shown to reduce the impact of stress and anxiety. Studies find that people who take ashwagandha have decreased blood pressure and pulse rate (7).
Ashwagandha is typically used in health supplements today to assist with physical endurance and stress management (2).
Ashwagandha is used in traditional African medicine for a variety of ailments (3) and has been used in Ayurvedic medicine in India as an adaptogenic herb for thousands of years (2). The traditional belief is that by ingesting the herb, it will make you as strong and virile as a horse. The roots of ashwagandha are traditionally used in Ayurvedic medicine to promote a calming effect on the body and mind. It is supplemented primarily for its ability to prevent anxiety. The anti-anxiety effect is also believed to be synergistic with alcohol.
Ashwagandha is often used in traditional medicine practices today for arthritis, anxiety, bipolar disorder, stress, attention deficit hyperactivity disorder, balance, insomnia, tumors, tuberculosis and chronic liver disease and multiple other disorders.
