Key TCM concepts behind chinese plums (Wu Mei)'s properties

In Traditional Chinese Medicine (TCM), chinese plums are plants that belong to the 'Herbs that stabilize and bind' category. This category of herbs is used for treating abnormal discharges and displacement of organs. This includes conditions such as diarrhea, discharges from the vagina, penis or rectum as well as prolapse of the uterus or rectum. It is important to note that herbs in this category only treat symptoms, so one should also use herbs to treat the underlying Deficiency.

Furthermore chinese plums are plants that are Neutral in nature. This means that chinese plums typically don'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 chinese plums means that you don't have to worry about that!

Chinese plums also taste Sour. The so-called "five elements" theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Sour ingredients like chinese plums help with digestion and restrain abnormal discharges of fluids from the body, such as diarrhea or heavy sweating.

The tastes of ingredients in TCM also determine what organs and meridians they target. As such chinese plums are thought to target the Spleen, the Large intestine, the Liver and the Lung. In TCM the Spleen assists with digestion, blood coagulation and fluid metabolism in the body. The Large Intestine on the other hand receives the "impure" parts of the digested food from the Small Intestine, absorbs the remaining fluids and excrete the remainder as feces. The Liver is often referred as the body's "general" because it is in charge of regulating the movements of Qi and body fluids. It also takes a leading role in balancing our emotions. In addition to performing respiration, the Lungs are thought to be a key part of the production chain for Qi and the body fluids that nourish the body.
