脾胃亦为人体的重要脏腑。脾为脏，胃为腑，胃为脾之表，脾为胃之表，有互相连带之关系。在胃有病之时
期，脾有时不连带同病；若脾有病时，则胃无有不连带同病者。脾实胃必热，其现象环唇红燥，或者崩裂起皮，
牙龈内必掀肿而红紫，大便必色深黄且兼黑，或燥结不通。此时即身体发热，食欲不振，精神疲倦，或呕吐味苦
兼酸，或大渴消水而泻黄汁。凡此等之症形，是胃热脾实而不和也。大部分为伤食停饮，日数一多，脾胃均因滞
生实热，是内里蕴成之热，而非外感温邪所发生的表热也。此点必须注意。以外感的表热，用清下之药，即可退
净。且最忌攻下剂，恐外邪下陷，热向里攻，起神经受炙而发抽搐，或外邪逗留中焦以成结胸。而此之内部实
热，不用清下之药，直不能去之也。故治此等内里实热之症，生石膏可用也，酒川军亦可用也。如用生石膏，是
用以清理脾胃之实热为主；如用酒川军，是用以荡涤肠胃而撤实热为主。若是其热尚未洪壮之程度，二者不可以
兼用。只要用其一，再佐以消滞清火通气等药，即可治愈也。脾力，既虚本无热，所以热者，因虚亦能生热，使
之然耳。脾虚胃即不能和，消化之能力薄弱也。其现象是全身微作热，而时有微汗，其手足心及前额后脑，必较他
处炽热。口虽作渴，而唇必惨白，口气必微弱。以手按之，而热不蒸手。或宿食不能消化，见乳而不欲食，有时
或吐或泻，此是脾虚胃热，虚热之症也。治法应以养脾为主，脾能传化谷气，胃之虚热自平。万不可再用消滞清
热药，以求速急退热进食。此已受伤的脾胃，转因克伐太过，愈行败坏成为痞积臌胀，成疳劳肢体漫肿也。应用
钱东阳之补脾益黄散，或调气益黄散，因症而用可也。若恐调气益黄散内之虫类燥血，可用六君子汤，加藿香、
胡黄连，补虚去热。
少加活灵药，以防其腻滞，亦是善法。如脾虚腹肿，肠时空鸣，因伤食而起者，以指弹之如鼓声，以手按之如
棉软，是气虚极，脾已无运用力。切不可用有通性药品，以防其虚脱也。宜用六君子汤，加黄 、浓朴，温中固
气，助其慢慢自能运化也。如脚与腿肿，加宣木瓜、大腹皮、紫菀茸等药，就补气药中，宣其下部络膜以消肿。
补虚益气药，亦可以借其宣力，以调和滞性也。
脾胃也是人体的重要脏腑。脾属于脏，胃属于腑，胃是脾的外在表现（表），脾是胃的外在表现（表），二者有着相互关联的关系。当胃发生病变时，脾有时不会连带患病；但如果脾发生病变，那么胃没有不连带患病的。脾实热则胃必热，其症状表现为嘴唇周围红燥，或者破裂脱皮，牙龈内部必然红肿且呈红紫色，大便颜色深黄且夹杂黑色，或者干燥结块不通畅。此时身体发热，食欲不振，精神疲倦，或者呕吐物味苦兼酸，或者极度口渴饮水后却腹泻出黄色汁液。凡是这些症状表现，都是胃热脾实而不调和。大部分情况是由于饮食停滞、水饮内停，日子一久，脾胃都因阻滞而生实热，这是体内蕴积而成的热，而不是外感温邪所引发的体表之热。这一点必须注意。对于外感引起的表热，使用清热泻下的药物，就可以退净。而且最忌讳使用攻下剂，恐怕外邪陷入体内，热邪向里进攻，导致神经受热煎熬而引发抽搐，或者外邪停留中焦形成结胸证。而这种内部的实热，如果不使用清热泻下的药物，根本无法去除。所以治疗这种内部实热的病症，可以使用生石膏，也可以使用酒制大黄。如果使用生石膏，主要是用来清理脾胃的实热；如果使用酒制大黄，主要是用来荡涤肠胃并撤除实热。如果热度还没有达到非常炽盛的程度，这两者不可以同时使用。只要选用其中一种，再辅以消食导滞、清火、通气等药物，就可以治愈。
脾的功能虚弱，本来没有热，之所以出现热象，是因为虚也能生热，使得身体如此罢了。脾虚则胃不能调和，消化能力薄弱。其症状表现为全身微微发热，并且时常有微汗，手足心以及前额和后脑勺，必定比其他部位更热。口中虽然感到口渴，但嘴唇必定惨白，口气必定微弱。用手触摸皮肤，感觉热量不蒸手。或者宿食不能消化，看见乳食不想吃，有时呕吐或腹泻，这是脾虚胃热、虚热的症状。治疗方法应以补养脾脏为主，脾能传输转化谷气，胃的虚热自然平息。万万不可再用消食导滞、清热的药物，以求快速退热和进食。这已经受伤的脾胃，反而因为过度克伐（攻伐），逐渐败坏，形成痞积、臌胀，甚至发展成疳劳、肢体浮肿。应当应用钱乙（钱东阳）的补脾益黄散，或者调气益黄散，根据症状选用即可。如果担心调气益黄散中的虫类药物过于燥血，可以使用六君子汤，加入藿香、胡黄连，以补虚清热。稍微加一点活灵药（此处指具有流通作用的药物，如木香或类似行气药，原文“活灵药”可能为特定称呼或笔误，依原文保留），以防药物滋腻滞塞，也是好方法。如果是脾虚导致腹部肿胀，肠间有空鸣声，因伤食引起的，用手指弹击腹部像鼓声一样，用手按压像棉花一样柔软，这是气虚到了极点，脾已经没有运化能力。切不可使用具有通泄性质的药品，以防虚脱。适宜使用六君子汤，加入厚朴、枳实（原文“黄 ”疑为枳实或厚朴之误，结合上下文“浓朴”及“温中固气”，通常配伍为厚朴、枳实，此处依原文语境推测为行气药，若严格按字面“黄”无法确定，但后文有“浓朴”，故此处提取实体时需注意，原文作“黄 、浓朴”，可能缺字，暂按原文提取或忽略缺失部分，但在翻译中需通顺，此处译为“加入厚朴等药”或保留原意），温中益气，帮助其慢慢自行运化。如果出现脚部和腿部肿胀，加入宣木瓜、大腹皮、紫菀茸等药物，在补气药中加入宣通下部络膜的药物以消除肿胀。补虚益气的药物，也可以借助其宣通之力，来调和滞涩的性质。
Spleen and Stomach are also important Zang-Fu organs in the human body. Spleen belongs to Zang (solid organs), Stomach belongs to Fu (hollow organs). Stomach is the exterior manifestation of Spleen, and Spleen is the exterior manifestation of Stomach; they have a mutually connected relationship. When disease occurs in the Stomach, the Spleen sometimes does not suffer from the same disease concurrently; however, if disease occurs in the Spleen, the Stomach invariably suffers from it concurrently. If Spleen excess-heat exists, Stomach must be hot. The manifestations include redness and dryness around the lips, or cracking and peeling; the gums inside must be swollen, red, and purplish; the stool must be dark yellow with black tinges, or dry and constipated. At this time, the body may have fever, loss of appetite, mental fatigue, or vomiting of bitter and sour taste, or extreme thirst with drinking leading to diarrhea of yellow fluid. All these symptoms indicate Stomach heat and Spleen excess without harmony. Most cases are due to food stagnation and retained fluids; as days pass, both Spleen and Stomach generate excess heat due to obstruction. This is internal accumulated heat, not the exterior heat caused by external warm pathogenic factors. This point must be noted. For exterior heat caused by external pathogens, using clearing and purgative medicines can eliminate it completely. Moreover, attacking purgatives are strictly contraindicated, lest the external pathogen sink inward, causing heat to attack internally, leading to nerve irritation and convulsions, or external pathogens lingering in the Middle Jiao forming chest binding (Jie Xiong). However, this internal excess heat cannot be removed without using clearing and purgative medicines. Therefore, to treat such internal excess heat conditions, Sheng Shi Gao (Raw Gypsum Fibrosum) can be used, and Jiu Chuan Jun (Wine-processed Rhubarb) can also be used. If Sheng Shi Gao is used, its main purpose is to clear Spleen and Stomach excess heat; if Jiu Chuan Jun is used, its main purpose is to cleanse the intestines and stomach and remove excess heat. If the heat has not reached a severe degree, both should not be used together. It suffices to use one of them, supplemented by medicines for resolving stagnation, clearing fire, and promoting Qi circulation, which can cure the condition.
Spleen function deficiency implies no inherent heat; the reason for heat appearing is that deficiency can generate heat, causing this state. Spleen deficiency leads to Stomach disharmony and weak digestive capacity. Manifestations include slight whole-body fever with occasional slight sweating; the palms, soles, forehead, and back of the head are necessarily hotter than other areas. Although there is thirst, the lips are pale white, and breath is weak. Touching the skin reveals no steaming heat. Or, undigested food remains, showing aversion to milk/food, with occasional vomiting or diarrhea; this is Spleen deficiency with Stomach heat, a deficiency-heat syndrome. The treatment method should focus on nourishing the Spleen. Once the Spleen can transport and transform grain Qi, the Stomach's deficiency heat will naturally subside. One must absolutely avoid using stagnation-resolving and heat-clearing medicines to seek rapid fever reduction and appetite recovery. These already injured Spleen and Stomach, if subjected to excessive attacking/clearing, will deteriorate further, forming Pi accumulation (abdominal mass), Gu distension (abdominal swelling), or developing into Gan labor (childhood malnutrition) with generalized limb edema. One should apply Qian Dongyang's Bu Pi Yi Huang San (Spleen-Nourishing Yellow-Supplementing Powder) or Tiao Qi Yi Huang San (Qi-Regulating Yellow-Supplementing Powder), chosen according to symptoms. If concerned about the blood-drying nature of insect ingredients in Tiao Qi Yi Huang San, Liu Jun Zi Tang (Six-Gentlemen Decoction) can be used, added with Huo Xiang (Patchouli Herb) and Hu Huang Lian (Coptis Rhizome or related herb for clearing deficiency heat), to tonify deficiency and remove heat. Adding a small amount of Huo Ling Yao (Active Spirit Medicine, likely referring to aromatic Qi-moving herbs like Mu Xiang) to prevent cloying stagnation is also a good method. If Spleen deficiency causes abdominal swelling, with empty borborygmus in the intestines, arising from food injury, tapping the abdomen produces a drum-like sound, and pressing feels soft like cotton; this indicates extreme Qi deficiency where the Spleen has lost its motility. Medicines with purgative properties must absolutely be avoided to prevent collapse. It is suitable to use Liu Jun Zi Tang (Six-Gentlemen Decoction), added with Hou Po (Magnolia Bark) and [missing character, likely Zhi Shi], to warm the Middle and consolidate Qi, assisting gradual self-transformation. If swelling occurs in the feet and legs, add Xuan Mu Gua (Chaenomeles Fruit), Da Fu Pi (Areca Peel), and Zi Wan Rong (Aster Flower Bud), etc., within the Qi-tonifying formula to promote circulation in the lower meridians to reduce swelling. Tonifying and Qi-supplementing medicines can also borrow their promoting power to harmonize stagnating properties.
