有一位患者胃气虚弱且痰湿壅盛，口舌生疮。服用滚痰丸后病情反而加重，出现持续呕吐腹泻、厌恶饮食、精神倦怠的症状，这是胃气受损的表现。我给予香砂六君子汤（第236方）服用数剂，症状稍有好转；随后改用补中益气汤加入茯苓、半夏，服用二十余剂后痊愈。
胃气不足，导致饮食不能正常消化，也能生成痰湿。因此，补中益气是治疗此类痰湿的方法。如果对于虚证却使用药性峻猛利下的药物，很少有不造成危险的。
另一位患者年龄超过四十岁，体态丰腴但元气虚弱，遇到风邪则畏寒战栗，劳累时口舌生疮，胸部常有痰液，眼睛经常发红干涩。服用八味丸后痊愈。（这是依据症状辨证施治。）
还有一位患者脾胃虚弱，起初服用养胃汤、枳术丸有效，但长期服用反而导致身体更虚，口舌生疮，劳累后症状加重，服用苦寒败毒的药物则引发呕吐。这是中焦气虚寒凉所致。
治疗方法先用理中汤，症状稍减；再用补中益气汤加入半夏、茯苓，一个月左右病情平稳。
养胃汤属于香燥类药物，如果是饮食停滞，或者寒邪阻滞中焦，服用它可以燥湿开脾，使宿食积滞消化，稍微接近医理。枳术丸属于消导类药物，虽然含有白术，但终究是燥剂。所以长期服用这两种药物，津液会更加干燥，胃气更加虚弱。何况患者胃气本已虚弱而使用这些药物，难道不是加重病情吗？也有因房事过度，导致真阳虚惫，或者先天禀赋不足，不能上蒸于中焦，导致脾胃运化无力，致使食欲不振的情况。用补真丸（第36方）治疗，使丹田之火上蒸脾土，则脾土温和，中焦自然调理，饮食自然增进。《内经》说：饮食不进，胸膈痞塞，或者食物不消化，大便溏泄，这都是真火不能上蒸脾土所造成的。如果肾气壮实，则丹田之火能上蒸脾土，就不会有这种病了。
另一方：使用黄丹。
A patient with weak stomach qi and abundant phlegm developed sores on the mouth and tongue. After taking Gun Tan Wan (Rolling Phlegm Pill), the condition worsened, accompanied by incessant vomiting and diarrhea, aversion to food, and fatigue. This indicated injury to the stomach qi. I prescribed Xiang Sha Liu Jun Zi Tang (Aromatic Sand Six Gentlemen Decoction) for several doses, which brought slight relief. Subsequently, Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction) was administered with added Fu Ling (Poria) and Ban Xia (Pinellia Rhizome) for over twenty doses, resulting in a cure.
Insufficient stomach qi leads to improper digestion of food, which can also generate phlegm. Therefore, tonifying the middle and augmenting qi is a method for treating such phlegm. If峻利之药 (harsh purgative/draining drugs) are used for deficiency syndromes, danger is rarely avoided.
Another patient, over forty years old, had a robust appearance but weak constitution. He experienced chills when exposed to wind and developed sores on the mouth and tongue upon exertion. He often had phlegm in the chest and red, dry eyes. He was cured after taking Ba Wei Wan (Eight-Ingredient Pill). (This case relied on symptom differentiation.)
A third patient with weak spleen and stomach initially responded well to Yang Wei Tang (Nourish Stomach Decoction) and Zhi Zhu Wan (Immature Bitter Orange and Atractylodes Macrocephala Pill). However, long-term use led to further deficiency, sores on the mouth and tongue that worsened with exertion, and vomiting upon taking bitter-cold detoxifying drugs. This was due to deficiency-cold in the middle jiao.
Treatment began with Li Zhong Tang (Regulate the Middle Decoction), which provided slight improvement. Then, Bu Zhong Yi Qi Tang with added Ban Xia (Pinellia Rhizome) and Fu Ling (Poria) was given, leading to stability within a month.
Yang Wei Tang consists of aromatic and drying herbs. If there is food stagnation or cold stagnation in the middle jiao, it can dry dampness, open the spleen and stomach, and digest retained food, which is somewhat reasonable. Zhi Zhu Wan is a digestive and guiding herb formula. Although it contains Bai Zhu (Atractylodes Macrocephala Rhizome), it is ultimately a drying agent. Thus, long-term use of these two formulas dries body fluids further and weakens stomach qi. Moreover, using them on a patient whose stomach qi is already deficient would inevitably aggravate the disease. There are also cases where excessive sexual activity leads to exhaustion of true yang, or innate insufficiency fails to steam upwards to the middle jiao, causing impaired transport and transformation, resulting in poor appetite. These are treated with Bu Zhen Wan (Tonify True Essence Pill) to enable the fire of the Dantian to steam the spleen earth. When the spleen earth becomes warm, the middle jiao regulates itself, and appetite returns. The Classic states: Poor appetite, chest and diaphragm fullness and obstruction, indigestion, or loose stools are all caused by the failure of true fire to steam the spleen earth. If kidney qi is strong, the fire of the Dantian steams the spleen earth, and this disease does not occur.
