According to the *Taiping Shenghui Fang*: Infantile gan sores occur on the face and nose, are neither itchy nor painful, and often exude fluid. Wherever the fluid flows, sores immediately form. They may also appear on other parts of the body, a condition commonly suffered by infants. This is caused by wind-dampness clashing with blood and qi, hence the lack of itching or pain, and thus named "gan sore." Qian Yi discussed external manifestations of gan sores: redness and erosion under the nose, where the child rubs their nose; sores form without scabbing, gradually spreading around the ears. For treating nasal sores and erosion, use Lanxiang San (Perilla Leaf Powder). For various sores, use Baifen San (White Powder). (Both formulas are detailed under the section "Nasal Gan").
Zhang Huan's Sizhen Dan: Treats various forms of gan disease characterized by emaciation, scorched yellow hair, and sores in the mouth and nose.
Dried Bufo bufo gargarizans (one specimen, remove four feet, split abdomen, insert half liang of Coptidis Rhizoma into the abdomen, suture with thread, wrap in three liang of wet paper, seal all sides with mud, fire with charcoal until thoroughly red, cool down, remove mud, grind to fine powder) Aloe (half liang, ground) Moschus (one fen, ground)
Mix all ingredients evenly, grind again until very fine, bind with wheat flour paste into pills the size of millet seeds. Administer five to seven pills per dose, taken with gruel broth, adjusting dosage according to the child's age and size.
Xiongdan Gao: Treats persistent gan sores.
Ursi Gallus (Bear Bile) Pythonis Gallus (Python Bile) Aloe (each half liang) Vitriolum Flavum (Yellow Alum) (one fen, preferably from Guazhou. Grind the above into fine powder, then add) Moschus (one fen) Bovis Calculus (Ox Gallstone) (one fen) Borax (One qian. All finely ground)
Grind all ingredients finely and uniformly, mix with three he of well water, place in a silver vessel, and simmer over boiling water until it becomes a paste. Apply a small amount to the affected area each time.
Formula for treating all types of gan toxicity with sores in children:
Meliae Cortex (Toosendan Fructus Bark) (five jin, chopped) Chuguye (Half liang, chopped) Glycyrrhizae Radix et Rhizoma (Licorice Root) Alumen (White Alum) (each two liang) Allii Cepae Album (Scallion White) (ten stalks)
Coarsely chop and mix evenly. Boil in five dou of water for five to seven boils. Add hot water as needed to wash the sores. For chronic cases, only two applications are needed for immediate effect.
*Tan Shi Shu Sheng* records: Treats infantile gan fatty sores, which mostly occur on the head, persisting for a long time without healing, as well as ear sores, etc.
Chlorocrysocolla (Malachite) Angelicae Dahuricae Radix (Bai Zhi) (equal parts)
