Sutra Neti
Sutra neti is a nasal cleansing yoga exercise wherein the nasal area and outer respiratory regions are decongested with the help of soft thread. Initially, the soft thread is inserted through one nostril and tries to bring out through the mouth. The same process should be repeated with another nostril.In Ayurveda and Yoga, there are four types of neti kriya - Sutra (String), Jala (Water), Dugdha (Milk), and Ghrita (Ghee) Neti. Sutra is practiced with a string and the other three types of neti kriya are done with a neti-pot to deliver the liquid into the nostril.
