里虚泄泻而渴者，此方主之。
胃虚而寒，则生泄泻。泻失津液，则令人渴。是方也，人参、甘草，所以补胃。木香、
丁香、肉桂，所以温胃。腹皮、青皮、半夏、前胡、赤苓，所以调胃。乃诃子者，所以止泻
而生津也。此亦以胃气为主。盖胃不虚寒，则泻自止，津液自生，而渴自除矣。陈文仲云∶
腹胀渴者，泻渴者，足指冷渴者，惊悸渴者，身温渴者，身热面 白色渴者，寒战渴不止者，
气急切牙渴者，饮水转水泻不已者，以上九证，即非热也，乃津液少，脾胃肌肉虚故耳。宜
木香散治之。如不愈，更加丁香、肉桂。昆谓痘色 白，手足寒，小便利，如是渴者虚也，
本方主之；若痘色红赤，大便秘，小便赤，如是渴者热也，非此方所宜，慎勿与之。
*Ginseng Radix et Rhizoma* (Renshen), *Cardamomi Fructus Albus* (Baikoukou), *Atractylodis Macrocephalae Rhizoma* (Baizhu), *Angelicae Sinensis Radix* (Danggui), *Caryophylli Flos* (Dingxiang), *Cinnamomi Cortex* (Rougui), *Magnoliae Officinalis Cortex* (Houpo), *Citri Reticulatae Pericarpium* (Chenpi), *Pinelliae Tuber* (Banxia), *Poria* (Fuling), *Aconiti Lateralis Radix Praeparata* (Fuzi), *Aquilariae Lignum Resinatum* (Muxiang).
For cases where the smallpox eruption lacks luster, fails to swell and rise, has roots that are not red, and presents with exterior deficiency and interior excess, this formula is indicated.
When the middle qi is sufficient and qi and blood are abundant, the smallpox will be lustrous and rise properly, with red and vibrant roots, avoiding complications such as itching and collapse. If middle qi is deficient, the exterior also becomes weak, and various symptoms arise. In this formula, *Ginseng Radix et Rhizoma*, *Atractylodis Macrocephalae Rhizoma*, *Poria*, and *Angelicae Sinensis Radix* are used to tonify the stomach; *Aconiti Lateralis Radix Praeparata*, *Cinnamomi Cortex*, *Caryophylli Flos*, and *Cardamomi Fructus Albus* are used to warm the stomach; *Pinelliae Tuber*, *Aquilariae Lignum Resinatum*, *Citri Reticulatae Pericarpium*, and *Magnoliae Officinalis Cortex* are used to regulate the stomach. The Stomach channel belongs to Yangming. Chen stated: "The Yangming channel governs the muscles. When stomach qi is sufficient, the muscles become warm, naturally achieving luster and swelling, without the risk of itching and collapse." This is indeed a profound insight.
*Aquilariae Lignum Resinatum*, *Caryophylli Flos*, *Cinnamomi Cortex*, *Ginseng Radix et Rhizoma*, *Aurantii Fructus Immaturus* (Qingpi), *Arecae Pericarpium* (Dafupi), *Pinelliae Tuber*, *Glycyrrhizae Radix et Rhizoma* (Gancao), *Peucedani Radix* (Qianhu), *Terminalia Chebulae Fructus* (Hezi), *Poria cum Rubro* (Chifuling).
For cases of interior deficiency leading to diarrhea accompanied by thirst, this formula is indicated.
Stomach deficiency with cold generates diarrhea. Diarrhea depletes body fluids, causing thirst. In this formula, *Ginseng Radix et Rhizoma* and *Glycyrrhizae Radix et Rhizoma* are used to tonify the stomach; *Aquilariae Lignum Resinatum*, *Caryophylli Flos*, and *Cinnamomi Cortex* are used to warm the stomach; *Arecae Pericarpium*, *Aurantii Fructus Immaturus*, *Pinelliae Tuber*, *Peucedani Radix*, and *Poria cum Rubro* are used to regulate the stomach. As for *Terminalia Chebulae Fructus*, it is used to stop diarrhea and generate body fluids. This approach also focuses on stomach qi. Generally, if the stomach is not deficient and cold, diarrhea will cease naturally, body fluids will regenerate, and thirst will be eliminated. Chen Wenzhong said: "Abdominal distension with thirst, diarrhea with thirst, cold toes with thirst, palpitations with fright and thirst, warm body with thirst, fever with pale face and thirst, severe chills with unceasing thirst, rapid breathing with teeth grinding and thirst, drinking water leading to incessant watery diarrhea—these nine conditions are not heat syndromes, but rather result from insufficient body fluids and deficiency of spleen, stomach, and muscles." One should treat them with *Muxiang San*. If there is no improvement, add *Caryophylli Flos* and *Cinnamomi Cortex*. I hold that if the smallpox color is pale, hands and feet are cold, urination is free, and thirst occurs under these circumstances, it is a deficiency syndrome, and this original formula is indicated. However, if the smallpox color is red, stool is dry, and urine is dark, and thirst occurs under these circumstances, it is a heat syndrome, which is not suitable for this formula; one must exercise caution and not administer it.
