Bi Xie is a king ingredient in Bi Xie Fen Qing Yin. Like the name indicates, it means it has more power than other ingredients in the formula.
In Bi Xie Fen Qing Yin, Bi Xie enters the Bladder, Liver, and Stomach Channels and removes Dampness by separating the turbid from the pure Fluids. Then it directs the turbid fluids out the body through the Bladder. It is thus one of the most important herbs in treating cloudy urinary difficulty or vaginal discharge.
In Traditional Chinese Medicine (TCM), Bi Xie 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 Bi Xie is Neutral in nature. This means that Bi Xie typically doesn't affect the balance in your body. Balance between Yin and Yang is a key health concept in TCM. Eating too many "Hot" (Yang) ingredients can lead to an imbalance whereby one has a Yang Excess. The inverse is true as well: too many "Cold" (Yin) ingredients can lead to a Yin Excess. The Neutral nature of Bi Xie means that you don't have to worry about that!
Bi Xie also tastes Bitter. 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. Bitter ingredients like Bi Xie tends to have a cleansing action on the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Bi Xie is thought to target the Bladder, the Stomach and the Liver. In TCM the impure water collected by the Kidneys that cannot be used by the body is sent to the Bladder for storage and excretion as urine. The Stomach on the other hand is responsible for receiving and ripening ingested food and fluids. It is also tasked with descending the digested elements downwards to the Small Intestine. The Liver is often referred as the body's "general" because it is in charge of regulating the movements of Qi and the Body Fluids. It also takes a leading role in balancing our emotions.
