Ingredients: Sang Bai Pi (Cortex Mori Radicis) (each 2 liang).
Preparation and Administration: Grind into powder, store in a porcelain vessel, and take small amounts daily mixed with hot tea.
Commentary: The above two formulas are specific remedies for the Hand-Taiyin Lung meridian. One might ask: Since the pathogenesis of cough varies, why are medications often targeted at the lung? Cough is a disease manifested through vocalization, thus it largely originates from the Lung meridian. The *Neijing* states: "The Lung corresponds to Metal, possessing a firm and tough nature; when struck, it produces sound. When pathogens strike the Lung, cough ensues." Furthermore, the Lung is the canopy of the five zang organs, governs qi, connects with the skin and hair, receives blood from all vessels, and distributes essence and qi. If any zang organ or meridian becomes obstructed, or if disturbed by the nine emotional factors, or affected by the six climatic exogenous pathogens, or triggered internally by dietary cold and heat, the Lung will be diseased. Therefore, although the root causes of cough may differ, treatment principles are often similar. Differences lie only in the severity of the disease, accompanying symptoms, and the variations in formula composition regarding odd/even pairings and warming/cooling properties.
