Key TCM concepts behind croton fruits (Ba Dou)'s properties

In Traditional Chinese Medicine (TCM), croton fruits are plants that belong to the 'Cathartic herbs that drain downward' category. The herbs in this category are those whose main purpose is to treat constipation. They're called 'cathartic' because they have an especially strong effect and should only be used for severe intestinal blockage or gastrointestinal swelling.

Furthermore croton fruits are plants that are Hot in nature. This means that croton fruits typically help people who have too much "cold" in their body. 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 croton fruits can help restore a harmonious balance between Yin and Yang.

Croton fruits also taste Pungent. The so-called "five elements" theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Pungent ingredients like croton fruits tend to promote the circulations of Qi and body fluids. That's why for instance someone tends to sweat a lot when they eat spicy/pungent food.

The tastes of ingredients in TCM also determine what organs and meridians they target. As such croton fruits are thought to target the Stomach 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 Large Intestine on the other hand receives the "impure" parts of the digested food from the Small Intestine, absorbs the remaining fluids and excrete the remainder as feces.
