Ayurveda, the traditional medical system of India, originated > 4000 yr ago. It is based on the theory that disease results from an imbalance of the body’s life force (prana). It aims to restore balance within the body. The balance of prana is determined by equilibrium of the 3 bodily qualities (doshas): vata, pitta, and kapha. Most people have a dominant dosha; the specific balance is unique to each person. (See also Overview of Integrative, Complementary, and Alternative Medicine.)
Evidence for Ayurveda
Ayurveda has been studied, including in allergic rhinitis, neurologic conditions, pain, and diabetes. As with other studies of whole medical systems, high-quality research is difficult to conduct (1).
Uses for Ayurveda
After determining the balance of doshas, practitioners design a treatment specifically tailored to each patient. Ayurveda uses diet, herbs, massage, meditation, movement, and therapeutic detoxification (panchakarma)—typically with enemas, oil massages, or nasal lavage—to restore balance within the body and with nature.
Possible Adverse Effects
In some of the herbal combinations used, heavy metals (mainly lead, mercury, and arsenic) are included. Several studies found that Ayurvedic herbal supplements contain heavy metals in doses that could cause toxicity (2, 3). Cases of heavy metal toxicity have been reported (4, 5).
