反花疮者，由风毒相搏所为。初生如饭粒，其头破则血出，便生恶肉，渐大有根，脓汁
出。肉反散如花状，因名反花疮。凡诸恶疮，久不瘥者，亦恶肉反出，如反花形。
人身上患诸疮，热气盛者，肿 痛，附畔别结聚，状如瘰 者，名为疮建，亦名疮根也
王烂疮者，由腑脏实热，皮肤虚，而受风湿，与热相搏，故初起作瘭浆，渐渐王烂，汁
流浸溃烂，故名王烂疮也。亦名王灼疮，其初作 浆，如汤火所灼也。又名洪烛疮，初
生如沸汤洒，作瘭浆，赤烂如火烛，故名洪烛也。
白头疮者，由体虚带风热，遍身生疮，疮似大疥，痒，渐白头而有脓，四边赤，疼痛是
此疮非痈非疽，非癣非疥，状如恶疮，或瘥或剧，人不能名，故名无名疮也。此亦是风
热搏于血气所生也。
猪灰疮者，坐处生疮，赤黑有窍，深如大豆许，四边青，中央坼作臼陷，而不甚痛，状
如猪灰，因以为名。此亦是风热搏于血气所生也。
诸疮久不瘥，触风冷，有恶肉，则搔、针、灸不觉痛，因以不痛为名。
雁疮者，其状生于体上，如湿癣、 疡，多着四肢，乃遍身。其疮大而热，疼痛。得此
疮者，常在春秋二月、八月。雁来时则发，雁去时便瘥，故以为名。亦云∶雁过荆汉之域，
Fan Hua Chuang (Reverse Flower Ulcer) is caused by the struggle between wind-toxin and other pathogens. Initially, it appears like a grain of rice; when the head breaks, blood flows out, followed by the growth of foul flesh. It gradually enlarges with a root base and discharges pus. The flesh spreads outward in a shape resembling a flower, hence the name Fan Hua Chuang. For all kinds of foul ulcers that fail to heal for a long time, foul flesh may also protrude in reverse, resembling the shape of a reverse flower.
When various sores occur on the human body, if heat qi is abundant, swelling and pain occur, with nodules forming separately adjacent to the sore, resembling Lu Li (scrofula), it is named Chuang Jian (Sore Root), also known as Chuang Gen.
Wang Lan Chuang (King Rotting Ulcer) is caused by excess heat in the fu-zang organs and deficiency in the skin, leading to the invasion of wind-dampness which struggles with heat. Thus, it initially presents as blisters, gradually becoming eroded, with fluid flowing and causing ulceration, hence the name Wang Lan Chuang. It is also called Wang Zhuo Chuang (King Burning Ulcer), as the initial blisters resemble burns from hot water or fire. It is also named Hong Zhu Chuang (Great Candle Ulcer); initially appearing like boiling water splashed on the skin, forming blisters, with redness and erosion resembling a burning candle, hence the name Hong Zhu.
Bai Tou Chuang (White Head Ulcer) is caused by bodily deficiency combined with wind-heat, resulting in sores all over the body. The sores resemble large scabies, are itchy, gradually develop white heads with pus, have red borders, and are painful.
This sore is neither Yong (carbuncle), nor Ju (deep abscess), nor Xuan (tinea), nor Jie (scabies). Its appearance resembles a foul ulcer; it sometimes heals and sometimes worsens, and people cannot name it, hence it is called Wu Ming Chuang (Nameless Ulcer). This is also generated by the struggle of wind-heat within the blood and qi.
Zhu Hui Chuang (Pig Ash Ulcer) occurs where one sits. The sore is reddish-black with pores, deep as a soybean, with greenish borders and a central fissure resembling a mortar depression. It is not very painful. Its shape resembles pig ash, hence the name. This is also generated by the struggle of wind-heat within the blood and qi.
For various sores that do not heal for a long time, upon exposure to wind-cold and the presence of foul flesh, scratching, acupuncture, and moxibustion do not elicit pain. Hence, it is named based on the lack of pain.
Yan Chuang (Goose Ulcer) manifests on the body, resembling wet tinea or ulcers, often affecting the limbs and even spreading over the whole body. The sores are large, hot, and painful. Those who contract this sore often suffer during the second month of spring and autumn. It flares up when geese arrive and heals when they depart, hence the name. Another theory states: when geese pass through the Jing-Han region, the sore resembles Ju-type lesions with small holes, resembling a honeycomb, hence the name. This is also generated by the struggle of wind-dampness within the blood and qi.
