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

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

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

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。
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.
