Vulvar pruritus in women is invariably caused by vaginal parasites (Yin Chong). When mild, it presents as itching; when severe, it manifests as pain, or with dripping purulent discharge. This condition is mostly transformed from damp-heat (Shi Re) and is named "parasitic erosion of the yin" (Yin Chong Shi). Internal treatment should clear liver fire (Gan Huo), primarily using Longdan Xiegan Tang (Gentian Liver-Draining Decoction) and Jiawei Xiaoyao San (Modified Free and Easy Wanderer Powder). External treatment involves grinding Tao Ren (Prunus Armeniaca Seed) into a paste, mixing it with Xionghuang powder (Realgar), or inserting it together with chicken liver into the vagina to suppress the parasites. However, nothing surpasses the efficacy of applying Yin Zhu Yan (Silver Cinnabar Smoke); inserting chicken liver containing the smoke into the vagina yields particularly excellent results.
Yin Zhu Yan (see *Xin Fang Ba Zhen · Yin Zhen*) treats head lice and various sores infested with parasites.
Take 4–5 fen of Yin Zhu (Cinnabar processed with sulfur), rub it onto thick paper, ignite it, and place it in a dry bowl. Cover it with a wet bowl that has gaps, so that the smoke adheres to the wet bowl. Then, use a finger to apply the smoke to the hair, cover with felt or silk, and all nits and lice will be eliminated. This smoke can be mixed with jujube flesh to form cakes or pills, or placed between cooked pig or chicken livers, applied to sores and tinea infested with parasites, or cases of parasitic erosion of the anus. Wrap the jujube pill in cotton, insert it into the anus overnight, and it will be miraculously effective. Ensure the cotton tail remains outside for easy removal.
Jiaozhu Tang (Pepper and Evodia Decoction) treats unbearable vulvar pruritus in women, where hot water washing is used, often too hot to keep hands immersed.
Huajiao (Zanthoxylum Fruit), Wuzhuyu (Evodia Fruit), Shechuangzi (Cnidium Fruit) (each 1 liang), Lilü (Veratrum Rhizome) (0.5 liang), Chencha (Aged Tea) (a pinch), Chaoyan (Stir-fried Salt) (2 liang). Decoct in 5 sheng of water, and fumigate/wash the area while hot.
Xingren Gao (Almond Paste) treats unbearable vulvar pruritus in women.
Xingren (Apricot Seed, burnt to retain its properties), Shexiang (Musk) (a small amount).
Grind the above into powder, wrap in old cloth, bind tightly, heat over fire, and insert into the vagina.
Chungenpi Tang (Toona Root Bark Decoction) treats vulvar pruritus with tissue prolapse.
Choukunpi (Toona Sinensis Root Bark), Jingjiesui (Schizonepeta Spike), Huoxiang (Patchouli Herb) (equal parts).
Decoct the above in water, fumigate and wash the affected area; itching ceases immediately and tissues retract.
Another prescription: Treats gan parasites eroding the lower part. Grind Puhuang (Lygodium Spore) and Shuiyin (Mercury) evenly, apply internally (Note: Excessive mercury enters the blood and can cause fatal poisoning). Externally, fumigate and wash with Heshicao (Dysphania Ambrosioides) decoction.
Zhigan San (Roasted Liver Powder) treats vulvar pruritus and parasitic erosion in women.
Use beef liver or pork liver, cut into pieces 3 cun long and the size of a coin, roast until cooked, and insert into the vagina. Once the parasites are fully drawn out, the condition resolves.
Another prescription: Treats parasitic itching in the vagina. Crush peach leaves, wrap in cotton, insert into the vagina, changing 3–4 times daily.
Another prescription: For vulvar pruritus as above. Shechuangzi (Cnidium Fruit) 1 liang, Baijian (Alum) 5 qian. Decoct in water and wash.
