Key TCM concepts behind cape jasmine fruits (Zhi Zi)'s properties

In Traditional Chinese Medicine (TCM), cape jasmine fruits are plants that belong to the 'Herbs that clear Heat and purge Fire and/or clear Summer Heat' category. Herbs in this category are used to clear inflammatory and infectious conditions, referred to as 'Internal Heat' in TCM. This is why most of the herbs in this category will have both antibacterial and antiviral properties. In TCM one has too much 'Heat' in their body as a result of a deficiency of 'Yin' (which is Cold in nature, see our explanation on Yin and Yang) or, more commonly, an excess of Yang (Hot in nature). Herbs that clear Heat and purge Fire treat the latter and as such tend to be Cold or Neutral in nature.

As suggested by its category cape jasmine fruits are plants that are Cold in nature. This means that cape jasmine fruits typically help people who have too much "heat" in their body. 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 cape jasmine fruits can help restore a harmonious balance between Yin and Yang.

Cape jasmine fruits also taste Bitter. 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. Bitter ingredients like cape jasmine fruits tend 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 cape jasmine fruits are thought to target the Gallbladder, the Heart, the Lung and the Sanjiao. Similar to modern medicine, in TCM the Gall Bladder stores and releases bile produced by the Liver. It also controls the emotion of decisiveness. In addition to regulating blood flow, the Heart is believed to be the store of the "spirit" which basically refers to someone's vitality. 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. The triple burner (Sanjiao) is a special concept in TCM with no corresponding organ in modern medicine. Its function is similar to a water wheel: body fuilds, Qi and food are transported through the San Jiao and that very movement helps our metabolism.
