Scientific Approach and Ayurvedic Mode of Action of Nasya in Netra Vyadhi (Eye Disorders): A Review

Nasya Karma is a kind of Panchakarma treatment for body cleansing used in Ayurveda. Nasya (medication through nasal route) karma comes under the one of Panchkarma Chikitsa which processes medicine given through the nose i.e Nasya. It is the single method of Chikitsa in which we use any form of medicine Sneha, Swaras (liquid), Churna (solid), and Dhoom (gas). It is the main treatment procedure for supraclavicular disease(urdhvajatrugat) and also for healthy wellbeing. Nasya is the only type of Chikitsa that fulfill the main aim of Ayurveda which is to maintain the health state of a healthy person and cures the disease of diseased ones. Nasya can use as a Shodhana (detoxification of body) as well as Shamana Chikitsa (pacification of exacerbated Dosha).Intranasally administered therapeutics reach the central nervous system (CNS) via the olfactory and trigeminal neural pathways. Both the olfactory and trigeminal nerves innervate the nasal cavity, providing a direct connection with the CNS.
