Kati Vasti is a simple, non-invasive, and deeply relaxing procedure performed by a trained therapist. The treatment typically lasts between 30 to 45 minutes.

Preparation: The patient lies face down on a Droni (Ayurvedic massage table). The exact area of pain or stiffness in the lower back is identified. A circular or ring-shaped dam is constructed over the painful area using thick, warm dough made from black gram flour or whole wheat flour. The ring is carefully sealed to the skin to prevent leaks.

Main Procedure: The reservoir created by the dough ring is slowly filled with lukewarm medicated oil (e.g., Mahanarayana Taila, Ksheerabala Taila, or Sahacharadi Taila). The oil temperature is crucial and is maintained throughout the treatment. The oil is kept on the back for a specific duration (typically 20-30 minutes). As the oil cools down, the therapist carefully removes the top layer of oil with cotton and replaces it with fresh, warm oil, ensuring the therapeutic warmth is consistent and continuous. This allows for maximum absorption of the medicinal properties.

Post-Therapy Care: After the prescribed time, the oil is removed, and the dough ring is gently peeled off. A gentle, localized back massage is often given to help the remaining oil penetrate deeper and relax the muscles further. The patient is advised to rest, keep the back warm, and avoid sudden or strenuous movements immediately after the treatment.
