Ayurveda, an ancient Indian system of medicine, emphasizes prevention of bodily ailments rather than solely treating symptoms. It is divided into eight branches collectively known as Ashtanga Ayurveda. Shalakya tantra is one of these branches, focusing on diseases affecting body parts above the clavicle bone, including the eyes, ears, mouth, nose, and head as described by Acharya Sushruta. The nose, or Nasa, serves not only as a respiratory organ but also as a pathway for drug administration. Nasya, a specialized procedure in Ayurveda, holds significant importance as a Shodhana method in treating Urdhwajatrugata Roga. The nose acts as a gateway to the head, facilitating the Nasya karma which helps in alleviating diseases of the upper parts of the body. This article explores the role of Nasya karma in Shalakya tantra.
