Dugdha neti is a yogic cleansing practice used to clear the nasal passageways. It is recommended in the “Hatha Yoga Pradipika” as well as other sacred yogic texts. It is considered important because nasal cleansing allows for easier breathing, which helps with pranayama and steady breathing during asana practice.
Dugdha neti is similar to jala neti in which a neti pot is used to cleanse the nasal passageways with warm saline solution, except that warm milk is used instead. It can be practiced in the same way as jala neti, using a neti pot, or a few drops of warm milk can simply be sniffed into each nostril at a time to coat and line the nasal passageways.
Dugdha neti may be especially useful after practicing jala neti and sutra neti, which may leave the nose feeling slightly sore or raw. It is also helpful as an alternative to jala neti for those who find saline solution irritates their nasal passageways.
