牙根肉红肿痛甚者是。刺出毒血，取珍珠散吹之，内服龙胆泻肝汤而愈。倘牙骨及腮内
疼痛，不肿不红，痛连脸骨者，是骨槽风也。倘以痈治，则害之矣。故治病贵在识症。
马曰∶牙痈乃胃火风热交攻，脓出即愈。至腮颊之肿不退，外溃则成穿腮漏。
患生于腮，有双有单，一曰遮腮，一日发颐，当宜别治。腮内酸痛是遮腮，取嫩膏敷
上，次
日痊愈。倘病仍两腮发肿，不酸痛者是发颐，宜服表风散毒之剂，当用白芷、天麻、防风、
荆芥各一钱，陈酒煎半碗，送服醒消丸而愈。
马曰∶遮腮以疏风清胃为主。如病后发颐，起耳根之下，肿连腮项，乃少阳邪热结聚，
须兼
顾本症。天麻、白芷、防风、醒消，均非所宜。盖此症发于温热病中，未能发汗解肌，热病
最易伤阴，故不得以辛温治之。
肾子作痛而不升上，外现红色者是也。迟则成患，溃烂致命。其未成脓者，用枸橘汤一
服即愈。
马曰∶子痈与囊痈有别。子痈则睾丸硬痛，睾丸不肿而囊肿者为囊痈。枸橘等品，正治
子痈之法。
阴囊生毒烂破，肾子落出。外用紫苏汤日洗，取紫苏叶、梗为末，日敷，用青荷叶包裹
，内服泻热汤。
马曰∶泻热汤治囊脱，颇效，可用。
初生小孩，因胎中受毒，腿上患色红肿成片，身热，名曰赤游。游者，游走也，游走遍
身而
死。取哺退鸡蛋内臭水，拂上一二次痊愈。或小孩口内生疳，或腮内生一红块，名曰螳螂子
，亦皆胎毒也。用生地五钱，生军一钱，陈酒浸透，取出共捣烂涂足心。男左女右，用绢缚
好，干即易，愈乃止。嫩膏涂游亦效。口疳用生香附、半夏等分为末，蛋白调作如饼，贴男
左女右涌泉穴，周时愈。涌泉穴即脚心。
马曰∶方内用蛋中臭水，一时难觅，不如以芭蕉根捣汁扫之，可退螳螂子。不可刀割。
牙根部位肌肉红肿疼痛剧烈的是牙痈。针刺放出毒血，取珍珠散吹入患处，内服龙胆泻肝汤即可痊愈。如果牙骨及腮内疼痛，不肿不红，且疼痛牵连到脸骨，这是骨槽风。如果把它当作痈来治疗，就会造成危害。所以治病贵在准确识别症状。马曰：牙痈是胃火与风热相互交攻所致，脓液排出后即刻痊愈。如果腮颊部的肿胀不退，外部溃破则会形成穿腮漏。
病变发生在腮部，有双侧和单侧之分，一种叫遮腮，一种叫发颐，应当分别治疗。腮内酸痛的是遮腮，取嫩膏敷在上面，次日即可痊愈。如果病情仍是两腮肿胀，但不酸痛，这是发颐，适宜服用疏散风邪、解毒的药物，应当使用白芷、天麻、防风、荆芥各一钱，用陈酒煎至半碗，送服醒消丸即可痊愈。
马曰：遮腮以疏风清胃为主要治法。如果是病后引发的发颐，起始于耳根之下，肿胀连及腮部和颈部，这是少阳经邪热结聚，必须兼顾根本病症。天麻、白芷、防风、醒消丸均不适宜。因为此症发生在温热病期间，未能通过发汗解除肌表之邪，热病最容易损伤阴液，所以不能用辛温的方法治疗。
肾子（睾丸）作痛且不向上提升，外部呈现红色的是子痈。拖延则成患，溃烂会危及生命。尚未成脓的，服用枸橘汤一剂即可痊愈。
马曰：子痈与囊痈是有区别的。子痈表现为睾丸硬痛，但睾丸本身不肿；而囊肿的是囊痈。枸橘等药物，正是治疗子痈的正法。
阴囊生毒腐烂破溃，肾子脱落外露。外用紫苏汤每日清洗，取紫苏叶、紫苏梗研为末，每日外敷，用青荷叶包裹，内服泻热汤。
马曰：泻热汤治疗囊脱，颇为有效，可以使用。
初生的小孩，因在胎中受毒，腿上出现色红肿胀成片，身体发热，名叫赤游。所谓“游”，是指游走，若游走遍身则会导致死亡。取哺退鸡蛋内的臭水，涂抹一两次即可痊愈。或者小孩口腔内生疳，或腮内生有一块红块，名叫螳螂子，也都属于胎毒。用生地五钱，生军（大黄）一钱，用陈酒浸透，取出共同捣烂涂于足心。男孩左足，女孩右足，用绢布绑好，干了就更换，痊愈为止。嫩膏涂抹赤游也有效。口疳用生香附、半夏等分为末，用蛋白调制成如饼状，贴于男孩左足、女孩右足的涌泉穴，一周时间可愈。涌泉穴即脚心。
马曰：方剂中使用蛋中臭水，一时难以寻找，不如用芭蕉根捣汁扫涂，可以消退螳螂子。不可用刀切割。
The condition characterized by severe redness, swelling, and pain of the gingival flesh is Ya Yong (Dental Abscess). Prick to release toxic blood, apply Zhenzhu San (Pearl Powder) by insufflation, and administer Longdan Xiegan Tang (Gentian Liver-Draining Decoction) internally for recovery. If there is pain in the dental bone and inside the cheek without redness or swelling, and the pain radiates to the facial bone, this is Gu Cao Feng (Bone-Cavity Wind). Treating it as an abscess would cause harm. Therefore, treating disease lies in accurately identifying symptoms. Ma said: Ya Yong (Dental Abscess) is caused by the mutual attack of Stomach Fire and Wind-Heat; it heals immediately upon pus discharge. If the swelling in the cheek does not subside and externally ulcerates, it becomes Chuan Sai Lou (Cheek-Penetrating Fistula).
The lesion occurs in the cheek, presenting as bilateral or unilateral. One type is called Zhe Sai (Cheek-Covering), and the other Fa Yi (Mumps/Parotitis); they should be treated differently. Soreness and pain inside the cheek indicate Zhe Sai (Cheek-Covering); apply Nen Gao (Tender Ointment) on top, and it will heal the next day. If both cheeks swell but without soreness or pain, this is Fa Yi (Mumps/Parotitis); it is appropriate to take formulas that disperse wind and detoxify. Use Baizhi (Angelicae Dahuricae Radix), Tianma (Gastrodiae Rhizoma), Fangfeng (Saposhnikoviae Radix), and Jingjie (Schizonepetae Spica), each 1 qian, decocted with aged wine to half a bowl, taken with Xingxiao Wan (Wake-Up Elimination Pill) for recovery.
Ma said: The main treatment for Zhe Sai (Cheek-Covering) is dispersing wind and clearing stomach heat. If Fa Yi (Mumps/Parotitis) occurs after an illness, starting below the ear root with swelling extending to the cheek and neck, it is due to the accumulation of Shaoyang pathogenic heat; one must attend to the underlying condition. Tianma (Gastrodiae Rhizoma), Baizhi (Angelicae Dahuricae Radix), Fangfeng (Saposhnikoviae Radix), and Xingxiao Wan (Wake-Up Elimination Pill) are not suitable. This condition arises during warm-heat diseases where sweating to resolve the muscle layer has failed; heat diseases easily damage Yin, so acrid-warm treatments must not be used.
Pain in the Shenzi (Testis) that does not ascend, with external redness, indicates Zi Yong (Testicular Abscess). Delay leads to complications, and ulceration can be fatal. For cases where pus has not yet formed, one dose of Gouju Tang (Citri Grandis Fructus Decoction) brings recovery.
Ma said: Zi Yong (Testicular Abscess) differs from Nang Yong (Scrotal Abscess). Zi Yong presents with hard, painful testicles without swelling of the testicle itself; Nang Yong presents with a swollen scrotum. Gouju (Citri Grandis Fructus) and similar herbs are the correct method for treating Zi Yong (Testicular Abscess).
When the scrotum develops toxicity, rots, and breaks open, causing the testicles to fall out, wash daily externally with Zisu Tang (Perilla Decoction). Take Zisu Ye (Perillae Folium) and Zisu Geng (Perillae Caudex), grind into powder, and apply externally daily. Wrap with fresh green lotus leaves, and administer Xi Re Tang (Heat-Draining Decoction) internally.
Ma said: Xi Re Tang (Heat-Draining Decoction) is quite effective for treating Nang Tuo (Scrotal Prolapse) and can be used.
Newborn infants, due to receiving toxins in the womb, develop red, swollen patches on the legs accompanied by fever, named Chi You (Red Roaming). "Roaming" refers to migration; if it roams over the entire body, it leads to death. Apply the foul water from inside hatched eggs once or twice for recovery. Alternatively, if an infant develops Gan (Mouth Thrush) in the mouth or a red lump in the cheek named Tang Lang Zi (Mantis Child), these are also fetal toxins. Use Dihuang (Rehmanniae Radix) 5 qian and Sheng Jun (Rhei Radix et Rhizoma) 1 qian, soak thoroughly in aged wine, remove, pound together into a paste, and apply to the sole of the foot. For males, the left foot; for females, the right foot. Bind well with silk cloth, change when dry, and stop when healed. Applying Nen Gao (Tender Ointment) to Chi You (Red Roaming) is also effective. For Kou Gan (Mouth Thrush), use Sheng Xiangfu (Cyperi Rhizoma) and Banxia (Pinelliae Rhizoma) in equal parts, grind into powder, mix with egg white to form a cake-like shape, and apply to the Yongquan point (KI-1) on the left foot of males and the right foot of females. It heals in one week. Yongquan (KI-1) is the center of the sole.
Ma said: Using foul water from eggs in the formula is difficult to obtain at times; instead, pounding Bajiao Gen (Musa Basjoo Radix) to extract juice and sweeping it can eliminate Tang Lang Zi (Mantis Child). Do not cut with a knife.
