Oil pulling is an ancient oral Kriya or practice recommended in Ayurvedic scriptures as an essential part of daily health rituals or Dinacharya.

Oil pulling includes two types of procedures. Gandusha- filling the mouth with a large quantity of oil and holding it in for about 10-15 minutes and Kavala -  filling the mouth with a relatively smaller quantity of oil, swishing it briskly inside the oral cavity and spitting it out after 2 to 3 minutes.
