Nasya is an Ayurvedic term, a procedure followed for disorders related to migraine, throat, nose, ear, sinusitis, and any other organ above the neck. Ayurveda purifies these organs and removes vitiated doshas through the nasal openings. The nasal treatment happens in the form of medicated powders, medicinal fumes, nasal oil, or medicated juice.
Nasya karma is the best procedure for treating Sirorogas (diseases affecting the head area) like migraine, chronic headaches, sinusitis, ear, nose and throat disorders. This involves the purification of the head region of the patient. In this process, the imbalanced doshas above the neck are removed through the nasal openings.
Nasal errhines are given to the patient in the form of medicinal oils, medicated powders or churnas, medicated juice/milk or medicinal fumes. The importance of this Panchakarma technique has been specified in the disease of the ear, nose and throat, mental diseases, toxicity, epilepsy, headaches, and untimely graying of the hair.
When Nasya is meant for Shodhana or Snehana, it is termed as Navana. This is the most common type of Navana and is used for hair fall, headaches and bells palsy tinnitus.
