Sheng Jiang Pi is a king ingredient in Wu Pi Yin. Like the name indicates, it means it has more power than other ingredients in the formula.
In Wu Pi Yin, Sheng Jiang Pi transforms Dampness and disperses Edema.
In Traditional Chinese Medicine (TCM), Sheng Jiang Pi belongs to the 'Herbs that drain Dampness' category. These herbs are typically diuretics, meaning that they promotes the increased production of urine in order to remove Dampness that has accumulated in the body. According to TCM Dampness accumulates first in the lower limbs, causing edema and impaired movement. From there, if unchecked, it can move upward and impair digestion and eventually the respiratory system.
Furthermore Sheng Jiang Pi is Cool in nature. This means that Sheng Jiang Pi tends to help people who have too much 'Heat' in their body, although with less effect than a plant that would be Cold in nature. Balance between Yin and Yang is a key health concept in TCM. Those who have too much Heat in their body are said to either have a Yang Excess (because Yang is Hot in nature) or a Yin deficiency (Yin is Cold in Nature). Depending on your condition Sheng Jiang Pi can help restore a harmonious balance between Yin and Yang.
Sheng Jiang Pi also tastes Pungent. The so-called 'Five Phases' theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Pungent ingredients like Sheng Jiang Pi tends to promote the circulations of Qi and Body Fluids. That's why for instance someone tends to sweat a lot when they eat spicy/pungent food.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Sheng Jiang Pi is thought to target the Spleen and the Lung. In TCM the Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. In addition to performing respiration, the Lungs are thought in TCM to be a key part of the production chain for Qi and the Body Fluids that nourish the body.
