According to the five elements in Chinese medicine, the root cause of liver qi in the stomach may be in the liver or in the stomach, and the two can affect each other. The stomach belongs to the earth and the liver belongs to the wood, according to the principle of the five elements, wood is equal to earth. 1. If the patient’s liver qi is stagnated due to poor emotional state or long-term depression, the liver will lose its function of draining, leading to transverse rebelliousness against the stomach (the liver’s qi is not flowing smoothly, thus infringing on the function of the stomach), which will in turn affect the transportation function of the spleen and the stomach, and this is called “wood exuberance multiplying the earth. 2. If the patient’s stomach qi is deficient, it means that the “earth” is more deficient, and it will appear that the “wood” is stronger, resulting in the disease being caused by too much mutual oppositions, i.e., “the earth is deficient and the wood multiplies it”. Regardless of where the root cause of liver qi is, Chinese medicine emphasizes a holistic approach and does not treat only the liver or the stomach, but usually adopts the approach of dredging the liver and the stomach, so that the liver and the stomach can be treated at the same time. It is recommended that the patient be treated under the guidance of a professional Chinese medicine practitioner.
