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.
Few well-designed studies of Ayurvedic practices have been done. Use of Ayurvedic herbal combinations to relieve symptoms in patients with RA has been studied. A 2005 systematic review1 identified randomized controlled trials that studied the efficacy of Ayurvedic herbal combinations for treatment of RA. Only a few high-quality studies were identified, but existing evidence did not demonstrate efficacy for treatment of RA. Use of Ayurvedic practices to treat diabetes is being studied.

After determining the balance of doshas, practitioners design a treatment specifically tailored to each patient. Ayurveda uses diet, herbs, massage, meditation, yoga, and therapeutic detoxification (panchakarma)—typically with enemas, oil massages, or nasal lavage—to restore balance within the body and with nature.
In some of the herbal combinations used, heavy metals (mainly lead, mercury, and arsenic) are included because they are thought to have therapeutic effects. Several studies1,2 found that about 20% of Ayurvedic herbal supplements were contaminated with heavy metals in doses that, if taken as directed, could cause toxicity; cases3 of heavy metal toxicity have been reported.
