When pathogenic heat from cold-damage disease transmits inward, leading to interior excess and exterior deficiency, yang toxin causes eruptions ⁽¹⁾.

1. . When blood heat fails to disperse and steams the skin, it results in eruptions, which may be mild like rashes or severe like brocade patterns. Purple-black eruptions indicate extreme heat and stomach decay, often leading to death. This may occur due to mistakenly administering hot herbs for yang pattern, premature purging allowing exterior heat to invade the stomach, or delayed purging causing heat to linger in the stomach, all of which can lead to eruptions. There are six types of eruption syndromes: cold-damage disease eruptions, which may result from premature or delayed purging; warm toxin disease eruptions, where cold is contracted in winter and manifests in spring; Rebing eruptions, where cold is contracted in winter and manifests in summer; seasonal epidemic eruptions caused by seasonal epidemic pathogens, with similar treatments; internal damage eruptions, where summerheat injury is followed by consuming cold foods, driving summerheat fire to float on the surface (Chinese Mosla and Hyacinth Bean should be added); and yin pattern eruptions, where original qi is severely deficient, cold is trapped below, driving rootless and unanchored fire upward to scorch the lungs and transmit to the skin, presenting as faint red and sparse eruptions (Major Center-Fortifying Decoction is suitable, but using cold formulas mistakenly can be fatal)

1. This is a Yangming stomach formula. Although the eruption of macules is due to stomach heat, the fire from other meridians also contributes to it. Indigo and Coptis Rhizome are used to clear liver heat, Gardenia to clear heart and lung fire, Scrophularia Root, Anemarrhena, and Unprocessed Rehmannia Root to clear kidney fire, and Rhinoceros Horn and Gypsum to clear stomach fire. These are all Great Cold (24th solar term) substances that can resolve toxic heat stagnation. Bupleurum is used to guide the effects to the surface of the skin, [Bupleurum clears Shaoyang ministerial fire.] Ginger and Jujube are used to harmonize the nutrient-defense system. Ginseng and Liquorice Root are used to harmonize the stomach. Stomach deficiency allows heat toxins to invade internally and manifest in the muscles. The addition of vinegar serves to astringe and consolidate.
