Shan Zha is an assistant ingredient in Pai Shi Tang. This means that it either serves to reinforces the effect of other ingredients or it moderates their toxicity.
In Pai Shi Tang, Shan Zha invigorates the Blood and breaks Blood Stagnation. It also improves digestion and reduces Food Stagnation.
In Traditional Chinese Medicine (TCM), Shan Zha belongs to the 'Herbs that relieve Food Stagnation' category. These herbs typically possess digestive and Food moving properties as they relate to the Stomach and Spleen. Some of these herbs are high in digestive enzymes and have varying specific abilities to help with the digestion of food.
Furthermore Shan Zha is Warm in nature. This means that Shan Zha 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 Shan Zha can help restore a harmonious balance between Yin and Yang.
Shan Zha also tastes Sour and Sweet. 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 Shan Zha helps with digestion and restrain abnormal discharges of Fluids from the body, such as diarrhea or heavy sweating. On the other hand Sweet ingredients tend to slow down acute reactions and detoxify the body. They also have a tonic effect because they replenish Qi and Blood.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Shan Zha is thought to target the Heart, the Liver, the Spleen and the Stomach. In addition to regulating Blood flow, in TCM the Heart is believed to be the store of the 'Mind' which basically refers to someone's vitality. 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. The Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. 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.
