In Traditional Chinese Medicine (TCM), Guan Zhong belongs to the 'Herbs that expel parasites' category. Herbs in this category are used to treat roundworms, tapeworm, hookworm and other intestinal parasites. In most cases, these herbs should be combined with other herbs to assist their action such as 'Purgative herbs that drain downward' or Qi tonics. Typically these herbs should only be prescribed for a short period as they often have some level of toxicity.

Furthermore Guan Zhong is Cold in nature. This means that Guan Zhong 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 Guan Zhong can help restore a harmonious balance between Yin and Yang.

Guan Zhong also tastes Bitter. 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 Guan Zhong tends to have a cleansing action on the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements.

The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Guan Zhong is thought to target the Stomach and the Liver. 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 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.
