Cultures around the world have customs and rituals for curing the common cold.
You may know it as “neti pot”, but he practice of nasal irrigation actually comes from as an ayurvedic yoga tradition in ancient India. Nasal irrigation is making a comeback even in Western countries as a cold remedy. Proponents use a rubber syringe to shoot warm salt water into nasal passages, let the water drip into the throat, and then spit out the water. The salt water is supposed to literally flush away the environment that houses the cold and alleviate symptoms.
