The *Bingyuan Lun* (Treatise on the Origins and Manifestations of Diseases) states: Jin Yin Chuang (Infiltrating Sore) is caused by wind-heat in the Heart affecting the skin and muscles. Initially, it appears very small, starting with itching followed by pain and the formation of sores. The exudate infiltrates the muscles, spreading gradually until it covers the entire body. If the sore starts from the mouth and spreads to the limbs, the condition is mild; if it originates in the limbs and then spreads to the mouth, the condition is severe. Because this sore grows and spreads progressively, it is named Jin Yin Chuang (Infiltrating Sore).

The *Ge Shi Fang* (Formulas by Master Ge) treats sudden onset of Jin Yin Chuang (Infiltrating Sore), where the lesion expands with exudate, often originating from the Heart channel. If not treated early, encircling the body can be fatal. Method: Apply blood from a rooster's comb to the affected area.

Another formula: Take fresh cow dung, squeeze out the juice, apply it topically, and fumigate the area with smoke from burning the dung for better efficacy.

Another formula: Take powder from swallow nests (Hu Yan Ke), mix with water, and apply as a poultice.

The *Lu Yan Fang* (Verified Formulas) Tian Ma Cao Tang (Decoction of Tian Ma Cao):
Chop five sheng of Tian Ma Cao (Arisaema Rhizome or similar herb contextually), boil in fifteen dou of water until one dou remains. Divide into portions to wash the affected area to relieve itching.

The *Ji Yao Fang* (Essential Formulas) treats sores on the body where exudate causes new sores upon contact, named Jin Yin Chuang (Infiltrating Sore), with unrelenting itching. Method:
Huang Lian (Coptidis Rhizoma, 1 liang), Huang Bo (Phellodendri Cortex, 1 liang), Lu Ru (Rubia Root, 1 liang), Shi Zhi (Kaolinite/Hematite, 1 liang), Gan Cao (Glycyrrhizae Radix, 1 liang), Sheng Hu Fen (Lead Carbonate, 1 liang).
Grind the Gan Cao and other ingredients into a powder. Roast the Hu Fen in a pan until yellow, then mix with the powder. Before application, wash the area with Ku Shen (Sophorae Flavescentis Radix) juice, dry with an old cloth, and immediately apply the medicine. It will heal within three to four applications.

Su Jing's *Bencao Zhu* (Commentary on Materia Medica) states: Chew raw Hu Ma (Sesame) and apply to the sore.

The *Ji Yan Fang* (Verified Formulas) treats sudden toxic qi attacking the body, causing swelling, redness, pain, or itching, with toxins spreading widely. Causing extreme distress throughout the body. Method:
Take raw fish, slice it as if preparing sashimi (Kuai), mix with salt, and apply as a poultice. If widespread, cover the entire diseased area. Replace when dry.

The *Qian Jin Fang* (Prescriptions Worth a Thousand Gold) treats Jin Yin Chuang (Infiltrating Sore):
Apply warm pancake (Jian Bing) as a hot compress to stop itching; this is miraculous and effective.

The *Bingyuan Lun* states: Wang Lan Chuang (Rotting Sore) is caused by excess heat in the fu-organs and deficiency in the skin, allowing wind-dampness to invade. Wind-dampness clashes with heat, initially forming blisters (Bao Jiang). These gradually rot and weep profusely, hence the name Wang Lan Chuang (Rotting Sore). It is also called Wang Zhuo Chuang (Scalding Sore) because the initial blisters resemble burns from boiling water or fire. It is also named Hong Zhu Chuang (Red Candle Sore) because the initial appearance resembles splashed boiling water, forming red, rotting sores like a burning candle.

The *Ge Shi Fang* treats adults and children with sudden Wang Zhuo Chuang (Scalding Sore), also known as Dan Chuang (Plague Sore) or Wang Lan Chuang (Rotting Sore). This sore initially forms blisters resembling fire blisters, hence the name referring to scalding and rotting.
Burn cow dung, sift the ash, and dust it onto the sore.

Another formula: Roast Su Mi (Millet) until yellow-black, grind, and apply.

Another formula: Boil Xiao Dou (Adzuki Bean) juice, add a chicken egg, strain, and use the liquid to wash the sore; this is effective.

Another formula: Powder Huang Lian (Coptidis Rhizoma) and Hu Fen (Lead Carbonate), mix with oil, and apply.

The *Duan Ju Fang* (Short Drama Formulas) describes Hong Zhu Chuang (Red Candle Sore), where blisters suddenly appear on the body like splashed boiling water. In severe cases, it covers the head and face, or the chest, ribs, waist, and abdomen feel like being scalded by boiling water, with blisters rising. Treatment method:
Urgently administer Lou Lu Tang (Radix Euphorbiae Humifusae Decoction) to purge downwards. Externally, bathe in Sheng Ma Tang (Cimicifugae Rhizoma Decoction), using double the dosage and boiling longer for bathing the affected area. During this period, applying Sheng Ma Gao (Cimicifugae Ointment) is excellent.
If no medicine is available in remote areas, follow the treatment methods for Dan Du (Erysipelas), using single-herb vegetable formulas. (This aligns with the *Qian Jin Fang*).

The *Fan Wang Fang* (Fan Wang's Formulas) treats Wang Lan Chuang (Rotting Sore):
Place Da Ma Zi (Hemp Seed) and Da Dou (Soybean) in a reed barrel. Heat and steam them, collect the juice from the top, and apply to the sore. Repeating twice leads to cure.

The *Seng Shen Fang* (Monk Shen's Formulas) treats Wang Lan Chuang (Rotting Sore):
Hu Fen (Lead Carbonate, roasted until yellow), Qing Mu Xiang (Aucklandiae Radix), Long Gu (Fossilized Bones), Hua Shi (Talcum) (each 3 liang).
Grind and sieve these four ingredients. Mix with one sheng of Ci Fen (Rice Flour). Dust lightly onto the sore four to five times daily until healed.
