If the spleen deficiency is due to liver qi stagnation (poor transportation of qi and blood in the liver and emotional depression), the liver needs to be treated first. According to Chinese medicine, the five elements are mutually reinforcing and the liver and wood are mutually reinforcing, and liver qi stagnation will damage the spleen and stomach over time, leading to spleen and stomach weakness, so the treatment of spleen deficiency needs to first focus on detoxifying the liver. If a patient with spleen deficiency is depressed and accompanied by symptoms of spleen and stomach weakness such as diarrhea, inappetence, abdominal pain, etc., it is usually due to liver qi stagnation. If Liver-Qi stagnation is predominant and is the cause of poor Spleen and Stomach, the focus of treatment should be on liver detoxification, along with medicines to strengthen the Spleen and harmonize the Stomach (restoring Spleen and Stomach functions) to regulate the condition. Since liver disease often affects the function of the spleen and stomach, spleen deficiency should be treated first, and then the spleen and stomach should be regulated for better clinical results. When discomfort occurs, one should consult a doctor in time, and choose medicines under the guidance of the physician’s diagnosis and standardized treatment, so as to avoid delaying the condition.
