Spleen qi deficiency, qi stagnation and blood stasis (blood stagnation due to lack of qi circulation), phlegm-dampness and dryness, this is a complicated disease caused by spleen qi deficiency, and it needs to be identified according to the severity of the symptoms. Those with obvious spleen qi deficiency can take Sijunzi Tang, those with obvious phlegm-dampness involving the stomach and internal organs can take Pingguxuan, Yiqi Tang, Ercheng Tang, etc, and those with obvious blood stasis can take Lost Laughing San, etc., and add and subtract for treatment. Spleen qi deficiency is not treated in time, it can develop into qi stagnation and blood stasis, followed by phlegm and dampness, and over time, it becomes dry, which is an evolving pathological process, in which various types of evidence will appear. First of all, to treat the root cause, the deficiency of spleen qi can be adjusted with the addition or subtraction of Si Jun Zi Tang. If you see dryness, you can add or subtract XuanShen, Maidong and other medicines to nourish Yin and benefit the stomach (replenish Yin and enhance the function of the stomach and internal organs). If phlegm-dampness obviously violates the stomach and viscera, it can take Pingguxan plus or minus, drying dampness and transporting the spleen, moving qi and stomach (through promoting the operation of qi to regulate the stomach and viscera); Er Chen Tang plus or minus, drying dampness and resolving phlegm (with drying dampness medicines to dispel phlegm in the body), regulating qi and zhong (regulating the qi of the spleen and stomach, so as to make the function of the spleen and stomach smooth). For those with obvious blood stasis and internal stagnation, Lost Smile San with additional reduction can be used for treatment. The adverse reactions and contraindications of the above formulae are not clear. If the spleen is deficient in qi, stagnation of qi, blood stasis, phlegm, dampness and dryness, it is necessary to be guided by a traditional Chinese medicine practitioner to analyze the severity of the disease, establish a treatment method to treat the root cause and the symptoms, and choose the appropriate formula with additions or subtractions to avoid improper use of medication and making a mistake in treating the patient’s condition.
