[Qian Yi] Each of the five Zang organs has a corresponding manifestation: the Liver corresponds to *shuidou* (water pox), the Lungs to *nongbao* (pus-filled blisters), the Heart to *banzhen* (macules and papules), the Spleen to *zhen* (rash), and if it归属于 the Kidneys, it turns black. [Hai Zang] The water pox of the Liver may appear greenish; the pus-filled blisters of the Lungs may appear white; the rash of the Spleen may resemble the color of bran; the macules/papules of the Heart are red; if the pathogen returns to the Kidneys, the color becomes black. These constitute the five colors. In general, for variola and exanthems, a single color indicates a favorable prognosis, whereas a mixture of two or three colors indicates an ominous prognosis. First, infants of varying sizes, having ingested the turbid blood of the five Zang organs during the ten months in the womb, must expel these toxins after birth. Therefore, the manifestations of sores and rashes are expressions of the fluids of the five Zang organs. The Liver governs tears, the Lungs govern nasal mucus, the Heart governs blood, and the Spleen envelops/controls blood. There are five names for these eruptions: The Liver manifests as *shuidou* (water pox) because tears flow like water, appearing greenish and small; the Lungs manifest as *nongbao* (pus-filled blisters) because nasal mucus is thick and turbid like pus, appearing white and large; the Heart manifests as *banzhen* (macules and papules), governing blood, appearing reddish and small, secondary to *shuidou*; the Spleen manifests as *zhen* (rash), appearing reddish-yellow and small. Because nasal mucus and tears are discharged abundantly, both *nongbao* and *shuidou* are larger; since blood nourishes internally and is not discharged as much, both *banzhen* and *zhen* are smaller. Furthermore, patients suffering from *shuidou* and *nongbao* have scanty nasal mucus and tears because the body fluids are expelled through the sores, similar to how a blister shrinks when the water inside is gone. [Lou Quanshan] The aforementioned *shuidou* is commonly known as waterpox; *nongbao* is commonly known as variola; *banzhen* is commonly known as sha-rash; *zhen* is commonly known as measles. Variola lesions are the largest, waterpox next, then macules/papules and rashes, with measles being the smallest, appearing faintly like millet seeds. [Zhang Huan] The sores of the four Zang organs differ in name and appearance. The Liver presents as *shuidou*, its fluid being tears which flow like water, slightly greenish and small. The Lungs present as *nongbao*, their fluid being nasal mucus which resembles pus, slightly whitish and large. The Heart governs blood, its sore being *banzhen*, reddish and small. The Spleen envelops blood, its sore being *zhen*, reddish-yellow and superficial. This describes their initial distinct appearances. However, after five to seven days, regardless of which organ they initially originated from, they all transform into blood spots (*xuexi*), blood spots turn into pus-filled blisters (*nongxi*), and after the pus-filled stage, scabs form and healing occurs. Some ask: If the Lungs present as *nongbao*, why do pus-filled blisters form again after the blood spots? The reason is that when the Lungs present as *nongbao*, it refers to the initial eruption being faintly like pus, white rather than yellow. The pus formed after the blood spots represents matured sores enclosing yellow pus, yellow rather than white. Although both are called pus-filled blisters, the nature of the pus differs. Similarly, the Spleen presenting as *zhen* refers to the initial appearance of slight yellow discoloration with small sores; its progression to pus, scabbing, and resolution differs significantly in substance from what is termed cutaneous rash. The Heart presenting as *banzhen* is also vastly different from conditions such as warm-toxin, winter-warmth, or eruptive macules. [Wan Mizhai] In observing the five Zang manifestations of sores and rashes, one must identify which Zang's syndrome is most severe, indicating that this Zang harbors the most toxin. If the Liver syndrome involves heavy toxin, it will inevitably produce *shuidou*, itching, and eye diseases; one should preemptively resolve Liver toxin using Qianghuo Tang (Notopterygium Decoction) augmented with Qingpi (Aurantii Fructus Pericarpium) and Chaihu (Bupleuri Radix). If the Lung syndrome involves heavy toxin, it will inevitably exacerbate wheezing, coughing, restlessness, and unceasing thirst, with the patient scratching eyebrows, eyes, nose, and face; one should preemptively resolve Lung toxin using Xiebai San (Drain the White Powder) combined with Ganjie Tang (Licorice and Platycodon Decoction), augmented with Niubangzi (Arctii Fructus) and Tianhuafen (Trichosanthis Radix). If the Heart syndrome involves heavy toxin, the patient will lie prostrate, speak deliriously, desire water, cry irritably, and grind teeth; one should preemptively resolve Heart toxin using Daochi San (Guide Out the Red Powder) augmented with Huanglian (Coptidis Rhizoma) and Chen Sha (Cinnabar). If the Spleen syndrome involves heavy toxin, the skin will turn grayish-white, accompanied by itching, vomiting, and diarrhea; one should preemptively nourish and protect the Spleen and Stomach to resolve the toxin, using Sijunzi Tang (Four Gentlemen Decoction) or Tiaoyuan Tang (Regulate Origin Decoction), augmented with Baishao Yao (Paeoniae Radix Alba), Fangfeng (Saposhnikoviae Radix), and Lianqiao (Forsythiae Fructus). The Kidneys do not present with mild syndromes; if the ears and eyes are both hot, it is a sign of death.
