Kun Bu is a deputy ingredient in San Zhong Kui Jian Tang. This means it helps the king ingredient(s) treat the main pattern or it serves to treat a coexisting pattern.
In San Zhong Kui Jian Tang, Kun Bu is salty, transforms Phlegm and softens hardness.
In Traditional Chinese Medicine (TCM), Kun Bu belongs to the 'Cool herbs that transform Phlegm and stop Cough' category. In TCM Phlegm is a condition of Stagnation of Fluids which tends to start in the Spleen and then goes to the Lungs. If this overly accumulates it thickens and becomes pathological Phlegm. Phlegm, being a form of Stagnation, often starts as being Cool and transforms to Hot as the condition progresses. The herbs in this category are Cold in nature so they treat the later stages of the Stagnation: Hot and Dry-Phlegm with symptoms such as cough, goiter or scrofula.
As suggested by its category Kun Bu is Cold in nature. This means that Kun Bu typically helps 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 Kun Bu can help restore a harmonious balance between Yin and Yang.
Kun Bu also tastes Salty. 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. Salty ingredients like Kun Bu tends to have a draining effect in the body because they clear accumulations, remove Phlegm and soften hard lumps.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Kun Bu is thought to target the Kidney, the Liver and the Stomach. According to TCM, 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 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 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.
