ANATOMICAL APPROACH TO MODE OF ACTION OF NASYA W.S.R SNEHANA NASYA - A REVIEW STUDY

In Ayurveda there are two folds of treatment one is Shodhana and the other is Shamana. Shodhana in-cludes panchakarma which is used to purify the body by removing the vitiated doshas of body. All five Panchakarma procedures act specifically on specific doshas. Sneha nasya i.e. administration of medicated oil through nasal cavities is one of the Panchakarma procedure which specifically used to treat Urdhva Jatrugata Vyadhis. According to Ayurveda, nose is the gateway of Shiras –brain , it can provide direct connection between brain and nasal mucosa and can transfer the administrated medicines from nose direct-ly to cranial cavity. This is why Nasya karma is used to treat diseases of head region which are generated by vitiated Kapha and Vata dosha. Medicated Sneha has lipid soluble substances which gets easily ab-sorbed by mucous membrane of nasal cavity and get easily transmitted to cranial cavity. The anatomical connectivity of nose with cranial cavity has been proved by modern science also. The direct nerve supply from CNS and the rich vascular supply to nasal cavity help to understand probable mode of action of Nasya Karma.
