Pichu is a palliative treatment for ailments of the head. A long piece of cloth (pichu) folded thickly and broader than the forehead is fixed around the head just above the ear level. A hole nearly one and a half inches wide is made in the front of the band. After preparatory procedures like an oil massage, the prescribed oil is applied on the head. A piece of cotton wad drenched in medicated oil is placed in the hole and allowed to remain there for some time. This process is repeated for a specific duration. Pichu, one of the Purvakarma therapy is considered effective for diseases of the cranial nerves arising from Vata disorder.
