Vasti is an Ayurvedic therapy that involves administering medicated oils or ghee through the rectum to nourish the tissues and relieve Vata problems, including ejaculation, constipation, and neurological disorders. The process is performed in a special tub called a "Snehana," filled with warm water. Before starting the treatment, a person is given “Snehana” to lubricate the intestines and relieve discomfort.
