For this purpose a towel is soaked in boiling water, the water is squeezed out, the warm towel is then waved, touched and pressed on the face and anterior neck. As soon as the boiling water is squeezed out of the towel, the towel is too hot, and therefore it is waved holding it just above the face and neck.

These conditions due to the provocation of dosha should be treated by Kapha alleviating measures. Further, administration of Nasya in emaciated persons, individuals who are just subjected to virechana karma, pregnant females and, subjects exhausted due to heavy physical exercise, and persons suffering from excessive thirst; lead to the vitiation of Vata dosha. This should be treated by Vata dosha. This should be treated by Vata alleviating measures as well as brahmana therapy. Snehana and svedana therapy are also indicated in this condition. A progressive cataract is the potential risk due to the erroneous Nasya karma in clients suffering from jvara (fever), afflicted with shoka (grief) or intoxicated due to alcoholic beverages. This complication should be treated by ruksha (dry) Anjana and putapaka.

This is carried out either by a towel soaked in warm water or by the method of nadi sveda. Gentle massage is done on the forehead, palms and soles of the client. He is then allowed to take rest in supine position for several minutes. Client is then allowed to wash his mouth and face with hot water.

Sudation is then continued by taking another pack of herbal leaves which is kept in the vessel for heating in the similar manner. In this way sudation is continued for about an hour. This completes the procedure of patrapinda sveda.
