Key TCM Concepts

In Traditional Chinese Medicine (TCM), Yu Mi Xu 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 Yu Mi Xu is Neutral in nature. This means that Yu Mi Xu 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 Yu Mi Xu means that you don't have to worry about that!

 

Yu Mi Xu also tastes Sweet. 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. Sweet ingredients like Yu Mi Xu tends to slow down acute reactions and detoxify the body. They also have a tonic effect because they replenish Qi and Blood.

 

The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Yu Mi Xu is thought to target the Bladder, the Liver and the Small intestine. 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 Liver on the other hand 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. Like the Stomach, the Small Intestine has a digestive role, extracting the "pure" part of what we injest to the Spleen and the "impure" down to the Large Intestine.
