Key TCM concepts behind flowering quince (Mu Gua)'s properties

In Traditional Chinese Medicine (TCM), flowering quince are plants that belong to the 'Herbs that dispel Wind and Dampness' category. These herbs typically help treat what's called 'bi pain' (i.e. painful obstruction) in TCM. This roughly corresponds to arthritic and rheumatic conditions with pain, stiffness and numbness of the bones, joints and muscles.

Furthermore flowering quince are plants that are Warm in nature. This means that flowering quince tend to help people who have too much 'Cold' in their body, although with less effect than a plant that would be Hot in nature. Balance between Yin and Yang is a key health concept in TCM. Those who have too much Cold in their body are said to either have a Yin Excess(because Yin is Cold in nature) or a Yang Deficiency (Yang is Hot in Nature). Depending on your condition flowering quince can help restore a harmonious balance between Yin and Yang.

Flowering quince also taste 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 flowering quince 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 flowering quince are thought to target the Spleen and the Liver. In TCM the Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. 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.
