Panch karma is five actions to cleanse and rejuvenate the body. Depending on your imbalance it might include massage, oil application, enema, sweating or induced vomiting. Panch karma works by pushing the toxins from storage (ie phlegm in the lungs or biribulin in the blood) to where it can be expelled, like the digestive system, and then expelling them, as well as strengthening the body so as not to provoke Vata.
My last Panch Karma, for high Vata Pitta includes oil massage, short sweats, shirodhara (oil on the forehead) and a series of oil enemas. I had treatment six days a week for two and a half months. As you can imagine this makes it a very holistic and gentle process.
I was on the long road to recovery from Hepatitis A and Giardia, but you don't have to be sick to have panch karma. It will stop the toxins from accumulating and spreading into deeper tissue like bones where it can cause disease.
