Those presenting with colored spots but without granular elevations are termed *Dan Du* (erysipelas, a condition characterized by red, swollen, hot, and painful skin lesions). Those presenting with granular elevations that appear and disappear immediately, only to reappear, are termed *Zhen* (rash). This pattern belongs to Wind-Heat pathogenic factor, complicated by Phlegm-Dampness. The pathology of *Zhen* involves Heat and Phlegm accumulating in the Lung organ; if the rash spreads from the limbs into the abdomen, the prognosis is fatal. It is also stated that *Yin Zhen* (urticaria) mostly pertains to the Spleen organ; it appears faintly within the skin, hence the name *Yin Zhen*. Upon eruption, it is mostly pruritic; if accompanied by numbness or loss of sensation, this indicates a differentiation involving Wind and Dampness. Red coloration indicates an accompanying Fire transformation. Mild Heat manifests as red macules/papules; severe Heat manifests as black macules/papules. Cases with red macules/papules have nine survivors for every one death; cases with black macules/papules have ten deaths for every one survivor.
The general treatment for *Zhen* should be adjusted according to the severity and specific circumstances.
