Vata’s predominant site is the colon. Ayurvedic basti (enema) involves the introduction into the rectum of herbal concoctions of sesame oil and certain herbal preparations in a liquid medium. Basti is the most effective treatment for vata disorders, although many enemas over a prescribed period of time are usually required. It relieves constipation, distention, chronic fever, cold, sexual disorders, kidney stones, heart pain, backache, sciatica and other pains in the joints. Many other vata disorders such as arthritis, rheumatism, gout, muscle spasms and headaches may also be treated with basti.
Vata is a very active principle in pathogenesis (disease). If we can control vata through the use of basti, we have gone a long way in going to the root cause of the vast majority of diseases. Vata is the main etiological (causal) factor in the manifestation of diseases. It is the motive force behind the elimination and retention of feces, urine, bile and other excreta. Vata is mainly located in the large intestine, but bone tissue (asthi dhatu) is also a site for vata. Hence the medication administered rectally effects asthi dhatu. The mucus membrane of the colon is related to the outer covering of the bones (periosteum), which nourishes the bones. Therefore, any medication given rectally goes into the deeper tissues, like bones, and corrects vata disorders.
