Prior to nasya karma, sneha and sweda should be done to the patients Face, Forehead, Head, Ears and Neck. This prior snehana (oleation) and swedana (sudation or sweating) will help to loosen the adhesive doshas, thereby facilitating the subsequent elimination.
Pradhan karma (Main Procedure of Nasyakarma)
After the Purvakarma the patient is asked to lie down in a bed with his hand and legs kept straight. His head is maintained at a lower position by keeping the pillow below the neck. This position will facilitate the direct passage of the drug. Placing the medicine above hot water gently warms it and then it is made to flow in to one nostril, while the other is kept closed the same process is carried out in the other nostril also. For the administration of the drug a pichu (Cotton swab) or nadi(tube) may be used (dropper can be used).
The sole, shoulder, neck, ear and palm are gently massaged after the administration of the drug. He must pit out all the impurities and medicine that reach his mouth. The spitting is repeatedly carried out turning to both sides while the patient is lying. Swedakarma (sudation) should be repeated after the nasya treatment.
The process of nasya can be repeated twice or thrice if necessary. This process should be repeated for 7 days.
