Piers Gibbon travels to India with Mark, who suffers from tinnitus and eczema, and Charles, who battles chronic migraines, to explore the healing properties of traditional local medicine. Guided by yoga master "Yogi Gi," the men start by using a rubber pipe to introduce a dollop of clarified butter into the nose. They also go under the knife for some vein slashing, get buried up to their necks in sand and finally sit down to reap the benefits of a tall glass of cow pee.
