Parasites in the anus arise from weak stomach Qi and empty intestines, allowing Ascaris lumbricoides (pinworms) to descend and invade. The anus is the external manifestation of the Large Intestine. Pinworms are one of the nine types of intestinal parasites.
For treating anal pruritus, or discharge of pus and blood, with parasites breeding within the orifices: Calocopris Pill Formula.
Calocopris (seven pieces, collected on the fifth day of the fifth lunar month, feet and wings removed, lightly roasted and pounded into powder), Fresh Cow Dung (half tael), Good Fatty Mutton (one tael, stir-fried until fragrant).
Pound all ingredients together into a paste. Shape into pills the size of lotus seeds. Heat them, wrap thinly in new cotton cloth, and insert into the lower orifice (anus). After half a day, after eating a little food, the parasites will be expelled completely in the stool. Three to five treatments will result in permanent cure.
Another formula:
Tribulus Terrestris Fruit (half tael, lightly roasted), Sulfur (one tael, finely ground), Gleditsia Sinensis Pod (one tael, burnt to ash).
Pound and sieve all ingredients into powder. Mix with sulfur until uniform. Use juice from Allium fistulosum (scallion) bulbs to bind into pills the size of lotus seeds. Wrap one pill in cotton cloth and insert into the lower orifice. Change two to three times daily.
Another formula:
Realgar (half tael), Lead Carbonate (Hufan) (half tael).
Finely grind both ingredients. Bind with jujube pulp into pills the size of lotus seeds. Wrap one pill in cotton cloth and insert into the lower orifice. Change twice daily.
Formula for treating lower body pruritus resembling insect crawling:
Cinnabar (one fen, finely ground), Alum (one tael, burnt to ash), Ligusticum Chuanxiong Rhizome (Chuanxiong).
Pound and sieve all ingredients into powder. Each time, take one qian wrapped in cotton cloth and insert into the lower orifice. Change twice daily.
Another formula:
Dead Snake (one piece, thickness like a finger).
Dig a pit in the ground, place the snake inside, and burn it. Cover the pit with a perforated board and sit on top to fumigate. The parasites will all be expelled.
The anus is the external manifestation of the Large Intestine. If its Qi is deficient, it is invaded by Wind-Heat pathogenic factors. The heat qi strikes and combats, causing anal erythema and pain.
For treating Large Intestine Wind-Heat invasion causing anal erythema and pain: Rheum Palmatum Decoction Powder Formula.
Rheum Palmatum Rhizome (Chuan Dahuang) (three qian), Paeonia Rubra Root (Chi Shaoyao) (half tael), Astragalus Membranaceus Root (Huangqi) (cut into pieces), Scutellaria Baicalensis Root (Huangqin), Scrophularia Ningpoensis Root (Xuanshen) (each one tael), Salvia Miltiorrhiza Root (Danshen) (three qian).
