患发耳后，又名耳后发，宜别阳实阴虚，治无一错。患色白者，以阳和丸与二陈汤同煎
服，
或以小金丹服消。如色红者，醒消丸服消。诸书不拘红白，概以元参、牛蒡、连翘、蚕尾、
赤芍、银花等七味以治，即色红者尚服不消，况色白者，能不遭其害乎？
马曰∶耳后锐毒，初有必有红根白头。肝肺二经邪火蕴结，又属少阳三焦部位。是经多
气少
血，阳和断不可服。若至溃后，气血两虚，邪从内陷，参、 、肉桂又当少少用之，托里补
虚。
又曰∶初起以疏风化痰为宜。盖锐毒即耳后发，与脑疽同。
患生脚骨，俗呼夹棍疽。未溃色白以疽治，红肿以痈治。如溃烂日久，形如驴眼者，莫
以疮治。当问初起红白，以疽痈别治。
马曰∶是症当以痈治为正。
脚底皮内生一泡，痛难步履。略去老皮，以生草乌酒磨涂上，速愈。如患生脚底之心，
名涌泉疽，当别红白色治。
马曰∶当作湿热治。色红者热甚，色白者湿重。
患者肛门前、阴根后，两相交界之处。初起细粒，渐如莲子大，数日后如桃李大，俗呼
偷粪
老鼠。溃经走泄，即成漏生管。漏久成怯。怯症人患此，乃催命鬼也。诸漏可医，独此难治
，治则漏管愈大，致成海底漏不救。在于未成脓时，用生甘草、制军各三钱，酒煎空心服，
一剂即愈。如成脓，以醒消丸愈之。倘患色白者，小金丹愈之。
马曰∶此漏亦有治法，不杂内症者可治。如见咳嗽发热，则不治矣。
又曰∶熟军、醒消、小金诸方，见阴虚咳嗽 不可投。
The lesion occurs behind the ear, also known as "post-auricular hair abscess" (Er Hou Fa). It is necessary to differentiate between excess syndrome of Yang and deficiency syndrome of Yin; treatment must be error-free. If the lesion color is white, administer Yanghe Wan (Yanghe Pill) decocted together with Erchen Tang (Two-Cured Decoction), or take Xiaojin Dan (Xiaojin Pill) to resolve it. If the lesion color is red, take Xingxiao Wan (Xingxiao Pill) to resolve it. Various medical texts, regardless of red or white color, uniformly treat with seven herbs: Xuanshen (Scrophulariae Radix), Niubangzi (Arctii Fructus), Lianqiao (Forsythiae Fructus), Canwei (Bombyx Batryticatus), Chishao (Paeoniae Radix Rubra), and Yinhua (Flos Lonicerae Japonicae). Even for red lesions, such treatment fails to resolve them, let alone white lesions, which would surely suffer harm.
Ma stated: Post-auricular sharp toxin (Er Hou Rui Du), in its initial stage, invariably presents with a red root and a white head. This is caused by the accumulation and knotting of pathogenic fire in the Liver and Lung meridians, and belongs to the region of the Shaoyang Sanjiao (Triple Burner). This meridian has abundant Qi but scarce Blood; therefore, Yanghe Wan must absolutely not be administered. If the condition progresses to ulceration, both Qi and Blood become deficient, and pathogens sink inward. In this case, Renshen (Ginseng Radix et Rhizoma) and Rougui (Cinnamomi Cortex) should be used in small amounts to expel toxins from the interior and tonify deficiency.
It is further stated: In the initial stage, dispersing wind and resolving phlegm is appropriate. Since sharp toxin is synonymous with post-auricular hair abscess, it is similar to Nao Ju (Brain Carbuncle).
A lesion occurring on the foot bone is commonly called "Jia Gun Ju" (Clamping Stick Carbuncle). If un-ulcerated and white in color, treat as Ju (Carbuncle); if red and swollen, treat as Yong (Abscess). If ulcerated for a long time with a shape resembling a donkey's eye, do not treat it as a common sore. One must inquire about the initial color (red or white) to differentiate between Ju and Yong and apply corresponding treatments.
Ma stated: For this condition, treating it as an Abscess (Yong) is the correct approach.
A blister forms inside the skin of the sole, causing pain so severe that walking is difficult. Slightly remove the old skin, grind Sheng Caowu (Radix Aconiti Kusnezoffii) in wine, and apply it topically for rapid recovery. If the lesion occurs at the center of the sole, it is named Yong Quan Ju (Yongquan Carbuncle), and treatment should be differentiated based on red or white color.
Ma stated: It should be treated as Damp-Heat syndrome. Red color indicates severe Heat; white color indicates heavy Dampness.
The lesion occurs at the junction of the front of the anus and the back of the genital root. Initially, it appears as fine granules, gradually enlarging to the size of a lotus seed, and after several days, to the size of a plum or peach. It is commonly called "Tou Fen Lao Shu" (Stealing Feces Mouse). Upon ulceration and leakage of pus, a fistula tract forms. Prolonged fistula leads to Qie Zheng (Debility Syndrome). When a patient with Debility Syndrome contracts this, it is akin to a life-threatening demon. While most fistulas are curable, this one is particularly difficult to treat; improper treatment may cause the fistula tract to enlarge, eventually resulting in Hai Di Lou (Sea-Bottom Fistula), which is incurable. Before suppuration occurs, use Sheng Gancao (Raw Glycyrrhizae Radix et Rhizoma) and Zhi Jun (Prepared Rheum Radix et Rhizoma), each 3 qian, decocted in wine and taken on an empty stomach; one dose results in cure. If suppuration has occurred, treat with Xingxiao Wan (Xingxiao Pill). If the lesion color is white, treat with Xiaojin Dan (Xiaojin Pill).
Ma stated: This type of fistula also has specific treatment methods; those without mixed internal symptoms are curable. However, if cough and fever appear, it becomes incurable.
It is further stated: Formulas such as Shu Jun (Cooked Rheum), Xingxiao Wan, and Xiaojin Dan must not be administered when Yin-deficiency cough is present.
