The Nasya Panchakarma or nasal therapy, also called Ayurvedic purification therapy, is a process used in ayurveda (traditional Indian system of medicine) and other healing methods. Using a specially designed neti pot (a small clay pot with one side facing upwards), which is inserted one nostril at a time, the physician helps the body to expel toxins through natural reflexes.

The process is best performed during springtime on an empty stomach to increase absorption and avoid digestion. One can also perform this treatment by using a water filter system, known as drik-kriyāorsujikix.

Clothing and food are removed, and a mixture of water and medicinal herbs is inserted into both nostrils. The patient then lies down on their abdomen with the head towards one side and the feet facing the other.

The practitioner inserts a spinning rod (tali) into one nostril, placing the end slightly deeper than the tip of the rod. This tilai is held in place for two to three minutes to help loosen mucus from various passages through which it runs. The patient then lies down for 15 minutes to allow mucus to exit through their other nostril via knuckles, nose, or eyes.
