When infantile erysipelas (Xiao'er Dan) erupts on both arms, presenting as red, raised lesions resembling plums, it is termed "Ghost Fire Erysipelas" (Guihuo Dan). The treatment formulas are as follows: Take five liang of Sedum aizoon (Jingtian Cao) and three liang of Dracocephalum heterophyllum (Sheyan Cao), pound them into a paste, and apply topically mixed with chicken blood. Another formula: Take one liang of Potassium Chloride (Rongyan) and one Aconitum carmichaelii root (Fuzi), burn them to ash, grind into powder, and apply topically mixed with male chicken blood.

Ingredients: Potassium Chloride (one liang), Aconitum carmichaelii root (one piece), Realgar (half liang, prepared by water flotation).

The *Shenghui Fang* records that when infantile erysipelas presents as red spots resembling plums, covering the back and abdomen, it is called "Wild Fire Erysipelas" (Yehuo Dan). The *Qianjin Fang* states that if the entire body is red, it is also called Wild Fire Erysipelas. Use half liang each of Realgar and Potassium Chloride, grind into powder, mix with egg white, and apply frequently until cured. Another formula: Take one liang of yellow earth from the stove and two liang of green bamboo leaves, burn to ash, grind into powder, and apply mixed with egg white. Another formula: Pound twenty-seven dried silkworms (Baijiangcan) and one liang of Huhucao into a pulp and apply. Alternatively, apply with wine or oil. Seal with a mixture of egg white and Vigna angularis seed powder; if widespread, apply over the whole body.
The *Shenghui Fang* records that when infantile erysipelas first appears on the cheeks, upper arms, and axillae, it is called "Home Fire Erysipelas" (Jiahuo Dan). Use three liang each of Phellodendron bark (Zimu Baipi) and Polygonum multiflorum leaves (Liaoye), burn to ash, mix with egg white, and apply frequently until cured.
The *Yingru Fang* records a formula for severe Home Fire Erysipelas invading the throat and abdomen:

Another formula: Aconitum kusnezoffii root (Wutou, one fen) and Red Halloysite (Chishizhi, three fen), grind finely, mix with egg white, and apply topically; this is highly effective.
The *Shenghui Fang* records that when infantile erysipelas first appears on the flanks, axillae, and legs, it is called "Calamity Fire Erysipelas" (Yanghuo Dan). Use Rhizoma et Radix Nitratae (Chuan Pu Xiao), grind into powder, take half qian per dose mixed with bamboo sap, adjusting dosage according to the child's age. Also, crush floating fern (Fuping) to extract juice and administer frequently.
