Vasti is the practice of applying heat to certain parts of the body. The process consists of creating a dam around an affected area and filling it with warm medicated oil. The oil is left to sit and penetrate the tissues, rejuvenating the body by easing the pain, swelling and tension. This therapy is excellent for abdominal, chest, back and knee issues. It helps provide relief from acute and chronic back pain, lumbar spondylosis, sciatica, osteoporosis, a prolapsed disc, lumbrosacral strain and rheumatoid arthritis.
