Key TCM concepts behind She Chuang Zi's properties

In Traditional Chinese Medicine (TCM), She Chuang Zi belongs to the 'Herbs for external application' category. Like the name indicates, this category of herbs is used mostly for external application in the form of powders, pastes or ointments. As such they are used to treat trauma, inflammation, swelling, bruises, bleeding, pain and so forth.

Furthermore She Chuang Zi is Warm in nature. This means that She Chuang Zi tends 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 She Chuang Zi can help restore a harmonious balance between Yin and Yang.

She Chuang Zi also tastes Bitter and Pungent. 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. Bitter ingredients like She Chuang Zi tends to have a cleansing action on the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements. On the other hand Pungent ingredients tend to promote the circulations of Qi and Body Fluids. That's why for instance someone tends to sweat a lot when they eat spicy/pungent food.

The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such She Chuang Zi is thought to target the Spleen and the Kidney. In TCM the Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. 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.
