Key TCM concepts behind Shi Liu Pi's properties

In Traditional Chinese Medicine (TCM), Shi Liu Pi belongs to the 'Herbs that stabilize and bind' category. This category of herbs is used for treating abnormal discharges and displacement of Organs. This includes conditions such as diarrhea, discharges from the vagina, penis or rectum as well as prolapse of the Uterus or rectum. It is important to note that herbs in this category only treat symptoms, so one should also use herbs to treat the underlying Deficiency.

Furthermore Shi Liu Pi is Warm in nature. This means that Shi Liu Pi 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 Shi Liu Pi can help restore a harmonious balance between Yin and Yang.

Shi Liu Pi 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 Shi Liu Pi 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 Shi Liu Pi is thought to target the Stomach, the Kidney and the Large intestine. In TCM the Stomach is responsible for receiving and ripening ingested food and fluids. It is also tasked with descending the digested elements downwards to the Small Intestine. 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. The Large Intestine receives the "impure" parts of the digested food from the Small Intestine, absorbs the remaining fluids and excrete the remainder as feces.

Research on Shi Liu Pi

Compared to the pulp, the pomegranate peel contains as much as three times the total amount of polyphenols, including condensed tannins, catechins, gallocatechins and prodelphinidins.1

Promising results against cardiovascular disease, diabetes, and prostate cancer have been reported from human clinical trials on the effect of pomegranate. The in vitro antioxidant activity of pomegranate has been attributed to its high polyphenolic content, specifically punicalagins, punicalins, gallagic acid, and ellagic acid. These compounds are metabolized during digestion to ellagic acid and urolithins, suggesting that the bioactive compounds that provide in vivo antioxidant activity may not be the same as those present in the whole food. Anthocyanins and the unique fatty acid profile of the seed oil may also play a role in pomegranate's health effects.2
