Ayurveda is a 5,000-year-old system of natural healing that has its origins in the Vedic culture of India. More than a mere system of treating illness, Ayurveda is a science of life (Ayur = life, Veda = science or knowledge). It offers a body of wisdom designed to help people stay vital while realizing their full human potential. Ayurveda has been enjoying a major resurgence in both its native land and throughout the world.

In laboratory studies at the Memorial Sloan Kettering Cancer Center, ashwagandha reduced growth of breast, central nervous system, colon, and lung cancer cells without affecting normal cells, but was not effective against drug-resistant cancer stem cells. Ashwagandha was also shown to prevent chemotherapy-induced neutropenia in mice.
