Vasti (administration of medicine through rectum) is another Sodhana or purification treatment. Vata is mainly located in the large intestine and bone tissue.
Vasti is the treatment where herbal medicines like medicated oils, decoctions, medicated milk or ghee are administered through rectum using an instrument called Vasthiyantra. There are three types of vasti:
The medicine for kashaya vasti is prepared by mixing honey, rock-salt, oil, herbal paste and decoction. First honey and rock salt are mixed in a vessel. Then oil is added and mixed well. This is followed by paste and then decoction until a homogenous mixture of all the ingredients is made. This mixture is filled in a sac made of leather warmed a little in hot water. The sac is then tied at the end of the vastiyantra. The leather sac containing medicine is pressed firmly once and medicine is injected into the rectum. A little of medicine is left in the sac to prevent air entering into the rectum. Then the patient should lie down on his back after completion of vasti. His abdomen should be massaged gently. When urge to pass stool, the patient can go to the toilet and evacuate. If he gets clear bowel movements then the treatment is successful. Afterwards he should take bath in warm water and take food.
The patient should take light food and then oil massage and bath are given. The instrument is then filled with the medicated oil and introduced into the rectum in the following manner. After this administration of the sneha (medicated oil) the person should lie down facing upward extending the entire body with a pillow under his heels. Then he should be given massage of abdomen, hands and feet. Oil should be smeared all over the body so that the sneha does not come out early. In normal case the enema liquid will go out after one or two hours. If the sneha returns properly at the right time the patient should fast at night and can take breakfast the next day morning.
