粪门生虫，奇痒万状，以人之势进出而后快者，此乃幼时为人戏耍，乘风而入之，故见此怪证也。（《石室秘录》）
蜜煎止痒丹（《石室秘录》）
蛇床子 楝树根（各三钱） 生甘草（一钱）

《心法》曰∶风疳者，乃风湿客于谷道，
形如风癣作痒，破流黄水浸淫，遍体微痛，宜用如圣散治之。
冯鲁瞻曰∶谷道痒痛，多因湿热生虫，欲成痔 ，宜以雄黄和艾烧烟熏之，或用
桃叶一斤，蒸之极热，纳小口瓶中，坐熏立死。
如圣膏
当归（五钱） 巴豆仁（三钱）
麻油八两熬枯，入黄蜡三两化尽，绢滤，入轻粉二钱，搅匀搽之。
《心法》曰∶股阳疽生于股之外侧，胯尖之后，其毒内搏骨节，脓深至骨，故漫肿不变色也。
《心法》曰∶股阴疽，一名赤施，发生于股内合缝下，近阴囊之侧，因偏在厥阴经，故名股阴也。
骑马痈，皆由少年人不保重，或串花街柳巷，或贪倚翠偎红，忍精而战，耐饥
而守，或将泄而提其气，或已走而再返其阳，或人方泄精，未经洗净，重与交合，皆
足以生此恶毒也。治以七味圣神汤主之。盖此毒乃乘虚而入，必大补其血，而佐以逐
邪之品，则病去如失，否则婉转留连，祸不旋踵，与其毒势弥漫，到后来发散，何
不乘其初起正气未衰，一剂而大加祛逐之为快哉！方中妙在用金银花，而以当归补血为君，人参为佐，大黄为使，重轻
多寡之得宜也。（《秘录》）
王肯堂曰∶骑马痈，乃手足三阴经所司，毒在肾经，湿热流于大小肠分，热血
积而为毒，缓治则成漏证，大小便俱从此出矣。此处不可用刀针，如用只可针一二分，慎之慎之。
《心法》曰∶骑马痈，亦名骗马坠，生于肾囊之旁，大腿根里侧股缝夹空中，由
肝肾湿火结滞而成，此处乃至阴之下，医治不可过用寒凉药。
Insects are generated in the anus, causing itching of extreme intensity, as if comfort is derived from their movement in and out with the force of the human body. This is due to playful teasing in childhood where wind pathogen entered through the opening, thus presenting this strange manifestation. (Shishi Milu)
Mi Jian Zhi Yang Dan (Honey-Fried Itch-Relieving Pill) (from Shishi Milu)
Cnidii Fructus (Shechuangzi), Melia Radix (Lianshugen) (each 3 qian), Raw Glycyrrhizae Radix et Rhizoma (Sheng Gancao) (1 qian).
Grind all into fine powder. Boil together with honey to form a suppository shaped like the male genitalia, insert into the anus, allow it to melt naturally. One dose stops the itching and cures the condition.
Xinfa states: Feng Gan (Wind-related Parasitic Disease) occurs when wind-dampness invades the Gu Dao (anus). The appearance resembles wind-xuan (wind-induced eczema/psoriasis) with intense itching; upon breaking, yellow fluid flows and spreads, accompanied by mild pain throughout the body. It should be treated with Ru Sheng San.
Feng Luzhan stated: Itching and pain in the Gu Dao are mostly caused by damp-heat generating insects, potentially developing into hemorrhoids. It is advisable to smoke with realgar mixed with mugwort, or take one jin of peach leaves, steam them until extremely hot, place them in a small-mouthed bottle, and sit over it to fumigate for immediate relief.
Ru Sheng Gao (Ru Sheng Ointment)
Angelicae Sinensis Radix (Danggui) (5 qian), Crotonis Semen (Badouren) (3 qian).
Boil eight liang of Sesame Oil (Mahu You) until the herbs are scorched, add three liang of Beeswax (Huang La) until fully melted, filter through silk cloth, add two qian of Calomel (Qingfen), stir evenly, and apply externally.
Xinfa states: Guyang Ju (Abscess on the Yang Aspect of the Thigh) arises on the lateral aspect of the thigh, behind the tip of the hip joint. The toxin binds inwardly to the bone joints, and the pus reaches deep to the bone, hence presenting as diffuse swelling without color change.
Xinfa states: Guyin Ju (Abscess on the Yin Aspect of the Thigh), also known as Chi Shi, occurs below the medial seam of the thigh, near the side of the scrotum. Because it lies偏 (biased/tending towards) the Foot Jueyin Liver Meridian, it is named Guyin Ju.
Qima Yong (Riding Horse Carbuncle) is caused by young people failing to protect their health, such as frequenting brothels, indulging in sexual pleasures, retaining semen during intercourse, enduring hunger while maintaining yang energy, forcibly holding back qi at the moment of ejaculation, or re-stimulating yang after ejaculation. It can also result from intercourse immediately after the partner has ejaculated without cleaning. All these factors are sufficient to generate this malignant toxicity. Treatment is primarily with Qi Wei Sheng Shen Tang. This toxicity enters via deficiency; therefore, one must greatly tonify blood and assist with products that expel pathogens. Then the disease will depart as easily as lost items returning. Otherwise, the condition will linger and tarry, and disaster will follow swiftly. Rather than waiting for the toxic momentum to spread widely before attempting to disperse it, is it not better to act while the righteous qi is still strong at the onset, using one dose to vigorously expel the pathogen? The brilliance of the formula lies in the use of Honeysuckle Flower (Jinyinhua), with Angelicae Sinensis Radix (Danggui) as the sovereign herb for nourishing blood, Ginseng Radix (Renshen) as the minister herb, and Rheum Radix et Rhizoma (Dahuang) as the guide herb. The appropriateness of weight and dosage is key. (Milu)
Weng Kentang stated: Qima Yong is governed by the Three Yin meridians of the hand and foot. The toxin resides in the Kidney Meridian, with damp-heat flowing into the Large and Small Intestines. Hot blood accumulates to form toxicity. If treatment is delayed, it becomes a fistula (Lou Zheng), with both urine and stool exiting from here. This area must not be cut with knives or needled. If needling is used, it should only be shallow, one or two fen. Exercise utmost caution.
Xinfa states: Qima Yong, also known as Pian Ma Zhui, arises beside the scrotum, in the hollow space between the inner thigh and the root of the leg. It is formed by the stagnation of damp-fire in the Liver and Kidneys. This location is the lowermost part of extreme yin; medical treatment must not overuse cold and cool medicines.
