Ayurveda suggests that the nose is the gateway to the head. Thus, nasal herb therapy is used for healing diseases of the throat, neck, head, and senses (e.g. ears, nose, eyes, etc.). Nasya is also used for toning and strengthening these areas. Nasya is helpful in head diseases caused by Kapha (e.g., stiffness, numbness, heaviness). Saturating Nasyas are recommended for Vayu disorders (e.g., facial paralysis, trembling head). Pacifying Nasyas are useful for internal bleeding and other Pitta head and neck disorders. Snuff is suggested three times daily in the rainy, autumn, and spring seasons when there are no clouds in the sky. Snuff is said to improve vision, smell, and hearing; keep hair from greying and falling out; prevent stiff neck, headache, and lockjaw. It is also said that snuff relieves chronic rhinitis, and head tumours. The veins, joints, ligaments, and tendons of the skull gain greater strength. The face becomes cheerful and well developed; the voice becomes more melodious. Nasya herbs include Bala, Vidanga, Bilva and Musta. They are made into an oil decoction with various other ingredients.
