In Traditional Chinese Medicine (TCM), evodia fruits are plants that belong to the 'Herbs that warm the Interior and/or expel Cold' category. Herbs in this category are used for Internal Coldness with Qi and Yang Deficiency. In the Yin and Yang system of thought (see our explanation on Yin and Yang) Yang is Hot in nature. A deficiency of Yang will therefore lead to Internal Coldness since there will as a result be more Yin (Cold in nature) than Yang. In extreme cases this can lead to so-called 'Yang collapse' with convulsions or coma and these herbs are particularly indicated to treat such scenarios.
As suggested by its category evodia fruits are plants that are Hot in nature. This means that evodia 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 evodia fruits can help restore a harmonious balance between Yin and Yang.
Evodia fruits also taste Bitter and 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. Bitter ingredients like evodia fruits tend to have a cleansing action on the body by clearing heat, drying dampness and promoting elimination via urination or bowel movements. On the other hand Pungent ingredients 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 evodia fruits are thought to target the Spleen, the Stomach, the Kidney and the Liver. In TCM the Spleen assists with digestion, blood coagulation and fluid 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. 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 is often referred as the body's "general" because it is in charge of regulating the movements of Qi and body fluids. It also takes a leading role in balancing our emotions.
Evodiamine (the active principle in Evodia fruits) possesses anti-cancer activities both in vitro and in vivo by inhibiting proliferation, invasion and metastasis, inducing apoptosis of a variety of tumor cell lines.1
