Diarrhea of spleen and stomach weakness syndrome is caused by spleen deficiency, and turbidity is not divided. Shen Ling Baizhu Powder (B pair) should be used for invigorating spleen and qi, eliminating dampness and stopping diarrhea. Gegen Qinlian Decoction is a representative prescription for diarrhea of damp-heat injury type (a misunderstanding). On the basis of this topic, if yang deficiency and spleen deficiency, yin and cold are abundant, Lizhong Pill can be used to warm the middle and dispel cold (C mistake). Huangqi Jianzhong decoction can warm the middle warmer to dispel cold, regulate stomach and relieve pain, and treat stomachache caused by deficiency and cold of spleen and stomach (D mistake). On the basis of this problem, if there is diarrhea for a long time, the middle qi sinks, or proctoptosis occurs at the same time, Buzhong Yiqi Decoction can be used to replenish qi and strengthen the spleen, and yang can be raised to stop diarrhea (E mistake).
