Oil pulling or oil swishing is a simple, cost effective, natural remedy that involves pulling or swishing oil in the mouth for 10 to 20 minutes. In Ayurveda, it is believed to "pull" all types of toxins out of the body and into the oil in the mouth, allowing you to spit out those toxins for oral and systemic health benefits. The oil should not be swallowed as it contains bacteria and toxins.
