According to *Zhu Bing Yuan Hou Lun* (Treatise on the Pathogenesis and Manifestations of All Diseases): Qu Su Chuang (Qu Chu Sores, sores caused by earwig bites) belongs to the category of sores, distinct from Yong Ju (carbuncles and furuncles). It is commonly said that "Qu Su" refers to this condition. It frequently occurs between the limbs, joints, and calves, often appearing symmetrically. The lesions form concentric rings of fine pores resembling needleheads, containing insects within, accompanied by itching and pain. Scratching causes yellow fluid to exude; the condition heals temporarily but recurs repeatedly. These are all caused by wind-pathogens invading the skin, leading to alterations in blood and qi. In some cases, superficial sores fail to heal for a prolonged period. Due to itching and pain, patients scratch them, or they are rubbed by clothing, causing the sores to remain unhealed for a long time and transform into Qu Su Chuang, wherein fine insects grow within the sores.
*Seng Shen Fang* (Prescriptions of Monk Shen) for treating Qu Su sores, scabies, carbuncles, and various other sores on the faces of men and women:
Fuzi (Prepared Aconite Lateralis Radix, 15 pieces), Shujiao (Sichuan Pepper Fructus Zanthoxyli, 1 sheng), Yege (Aristolochia debilis Radix, 1 chi 5 cun, heart removed).
The above three herbs are cut into small pieces, soaked in vinegar overnight, then added with 2 sheng of lard (Su Gao). Boil until Fuzi yields a yellow ointment. Apply to the sores. This formula also treats Shang Han (Cold Damage Syndrome) and undigested food retention. Take orally with wine, in doses the size of a jujube, and cover with blankets to induce sweating.
*Luo Yan Fang* (Verified Records Prescriptions) for treating Qu Su sores with insects and itching, Fuzi San Powder:
Fuzi (Prepared Aconite Lateralis Radix, 8 fen, processed by frying), Lilu (Veratrum nigrum Rhizoma, 2 fen, roasted).
Grind these two herbs together and sift. Apply the powder into the sores, three times daily.
*Fan Wang Fang* (Prescriptions of Fan Wang) for treating Qu Su sores: Use Hufen (Basic Lead Carbonate), mix with lard to a paste consistency, and apply to the sores. Effective.
*Liu Juanzi Fang* (Prescriptions of Liu Juanzi) for treating Qu Su sores:
Cuttlefish bone (Sepiae Endoconcha, ground into powder), mixed with 14 carp gallbladders (Cyprini Carassii Vesica Bilei). Prepare as a powder and apply to the sores. Healing occurs in less than three days.
*Ge Shi Fang* (Prescriptions of Ge Shi) for sudden onset of Qu Su urine sores: These sores encircle the waist and hypochondrium, causing severe acute pain.
Salt (3 sheng), boiled in water (1 dou) until reduced to 6 sheng. While hot, soak cotton cloth in the decoction and apply to the sores.
Another prescription: Burn deer antler (Cervi Cornu Degelatinatum), mix with vinegar, and apply.
Another prescription: Burn leather scraps and branches to ash, and apply.
Another prescription: Grind Adzuki bean (Vigna angularis Semen) into powder, mix with vinegar for application. If the area is dry, mix with lard for application.
Another prescription: Apply Hufen (Basic Lead Carbonate).
Another prescription: Grind earthworm feces (Eiseniae Foetidae Excrementum) into powder and apply.
*Duan Ji Fang* (Short Drama Prescriptions) states: When bitten by a viper (Fu She), illness ensues after resting. The symptom is sudden, intense pain in a specific area of the body. The pain feels like thorns pricking, similar to insect stings. Subsequently, fine rashes appear, clustering like fruits of the Chinese cornel (Zhu Yu). The edges of the rash are red, with white pus centers resembling millet grains. This also causes rapid swelling of skin and flesh, aversion to cold, and high fever. In severe cases, the rash spreads continuously across the waist, hypochondrium, chest, and back.
At the initial stage, immediately rub rhinoceros horn (Rhinocerotis Cornu) with water and apply to stop the toxicity. Treat according to the method for Huo Dan (Fire Carbuncle) and using single herbal remedies.
It is also stated: When bitten by a viper, before the sore appears, the sensation resembles an attack by the She Gong (Shooting Arrow bug). She Gong sores typically present as a single dark/black lesion. Viper bites present as clustered lesions. The pain differs slightly due to small rashes, but it is not a fatal disease.
*Qian Jin Fang* (Essential Prescriptions Worth a Thousand Gold) for treating viper bite sores:
Apply mud from human urine pits. Cures immediately. Highly effective; no other prescriptions needed.
Another prescription: Chew barley (Hordei Vulgaris Fructus) thoroughly and apply to the site, three times daily.
Another prescription: Crush fermented soybeans (Sojae Preparata) and apply as a poultice.
Another prescription: Thoroughly chew pear leaves (Pyrus bretschneideri Folium) and apply. (Same as *Ji Yao Fang*).
*Ji Yao Fang* (Urgent Essential Prescriptions) for treating Qu Su urine sores with continuous exudation of yellow fluid:
Wash with Licorice root decoction (Gancao Tang).
Another prescription: Crush leek juice (Jiu Cai Zhi) and apply.
Another prescription: Chew hemp seeds (Huo Ma Ren) and apply.
Another prescription: Mix Phellodendron bark powder (Huangbai Mo) with lard and apply. Wash with salt water solution the next day.
Another prescription: Chew cinnamon twig (Guizhi) and apply.
*Ru Yi Fang* (As-You-Wish Prescriptions) for treating Qu Su sores:
Apply Chicken Intestine Grass (Ji Chang Cao, *Polygonum aviculare*).
*Guang Ji Fang* (Broad Salvation Prescriptions) for treating Qu Su urine sores encircling the waist with unbearable pain:
Boil old rush fan (Bai Pu Shan) to extract juice and wash the area.
Another prescription: Crush flat bean leaves (Bian Dou Ye) to extract juice and apply. Immediate effect.
*Ji Yan Fang* (Collected Verified Prescriptions) for treating Qu Su sores:
Take half a jin of elm bark (Huai Bai Pi), cut into pieces, and soak in 2 sheng of vinegar for half a day. Scrape the surface of the sore and wash with this liquid, five to six times daily.
Another prescription: Mix lard with soil from swallow nests (Yan Chao Tu), blend with vinegar, and apply.
