Janu Vasti is a simple, non-invasive, and highly effective localized treatment performed by a trained therapist. The procedure typically lasts between 30 to 45 minutes.

Preparation: The patient lies comfortably on their back. The affected knee joint is cleaned. A circular or ring-shaped dam is constructed over the knee cap and surrounding area using thick, warm dough made from black gram flour or whole wheat flour. The dough ring must be leak-proof and firmly fixed to the skin.

Main Procedure: The reservoir created by the dough ring is slowly filled with lukewarm medicated oil (e.g., Mahanarayana Taila, Ksheerabala Taila, or Dhanwantharam Taila). The oil temperature is carefully maintained to ensure patient comfort and optimal penetration. The oil is kept on the joint for a specified duration (typically 20-30 minutes). During the procedure, the therapist continuously monitors the oil temperature and replenishes or reheats the oil to maintain a consistent therapeutic warmth, allowing the medicinal properties to permeate the joint structures.

Post-Therapy Care: After the prescribed time, the oil is removed from the reservoir, and the dough ring is taken off. A gentle, localized massage is given to the knee area to help the remaining oil penetrate deeper. The patient is advised to rest the joint and avoid strenuous activity immediately after the treatment.
