Tibetan traditional medicine, or Sowa Rigpa, centers on the "Three Principles Theory," where "Long" governs respiration and circulation, "Chiba" manages digestion and metabolism, and "Peigen" regulates fluid balance. Harmony among these principles sustains bodily health in Xizang. A key part of this medicine is traditional head therapy, which involves applying a compress of roasted grains and herbs onto the head with a special device that keeps the top warm. This therapy can ease headaches, insomnia, and related conditions.
