Key TCM concepts behind Bu Zha Ye's properties

In Traditional Chinese Medicine (TCM), Bu Zha Ye 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 Bu Zha Ye is Cool in nature. This means that Bu Zha Ye tends to help people who have too much 'Heat' in their body, although with less effect than a plant that would be Cold in nature. 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 Bu Zha Ye can help restore a harmonious balance between Yin and Yang.

Bu Zha Ye 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 Bu Zha Ye 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 Bu Zha Ye is thought to target the Spleen and the Stomach. In TCM the Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. The Stomach on the other hand is responsible for receiving and ripening ingested food and fluids. It is also tasked with descending the digested elements downwards to the Small Intestine.
