Key TCM concepts behind Mei Gui Qie's properties

In Traditional Chinese Medicine (TCM), Mei Gui Qie belongs to the 'Herbs that relieve coughing and wheezing' category. In TCM Phlegm is a condition of Stagnation of Fluids which tends to start in the Spleen and then goes to the Lungs. If this overly accumulates it thickens and becomes pathological Phlegm. Phlegm, being a form of Stagnation, often starts as being Cool and transforms to Hot as the condition progresses. Herbs that relieve coughing and wheezing treat branch symptoms of this Stagnation and tend to have antitussive, expectorant, diuretic or laxative properties.

Furthermore Mei Gui Qie is Cool in nature. This means that Mei Gui Qie 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 Mei Gui Qie can help restore a harmonious balance between Yin and Yang.

Mei Gui Qie also tastes Sour. 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. Sour ingredients like Mei Gui Qie helps 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 Mei Gui Qie is thought to target the Kidney. According to TCM, the Kidneys do not only regulate the urinary system but also play a key role in the reproductive system and the growth and aging process of the body.
