落下颏者，气虚之故，不能收束关窍也。患者平身正坐，以两手托住下颏，左
右大指入口内纳槽牙上，端紧下颏用力往肩下捺开关窍，向脑后送上即投关窍，随
用绢条兜颏放顶上，半时许去之，即愈。
脱颏起于肺肾虚损，元神不足，或笑谈高兴忘倦，一时元气不能接续所致。如
法拿上，须避风，速服加味六君子汤，不然风邪外受，必致痰涎壅盛，口眼 斜，而
风中脏腑，十无一瘳矣。（《集验》）
加味六君子汤（《集验》）。
人参 白术 白茯苓 半夏（各一钱五分） 天麻（火煨） 陈皮（各一钱） 僵蚕（酒炒，去丝） 当
归（各二钱） 附子（滚汤泡去皮、脐，六分） 川芎（八分） 甘草（三分）
灯心四十根，生姜三片，水煎服。
落下颏 口噙乌梅一二枚，茶倾自上。
落下颏 乌梅捣碎作饼，塞满牙尽头处，张口流涎，随手托上。
陈实功曰∶人咬为患，良肉受伤，但阳明胃经所属者齿，脏腑多火多热。凡食
经此，无不 烂下咽，又饮食炙 之毒，无不侵袭。故伤人发肿，其痛异常，臭脓腐
烂，痛彻连心，是感受牙齿之毒也。初咬时一日内，众人撒热尿浸伤处，洗净牙黄
瘀血，咬孔上蟾酥饼贴之，膏盖后出微脓渐愈。如初咬时未有此法，致肿痛发胖痛
甚者，亦与童便洗净挹干，用粗纸捻蘸麻
油，点火用烟焰熏肿痛上，良久方住，以解其毒；仍以蟾酥条插入，太乙膏盖，候
肿消时换玉红膏搓之，长肉完口。（《正宗》）
下巴脱臼（落下颏），是由于气虚的缘故，导致无法约束关节窍穴。患者端正坐姿，用双手托住下巴，左右手的大拇指伸入口内按在槽牙上，紧紧固定住下巴并用力向下颌方向按压以开启关节，随后向脑后上方推送使其复位归位。随即用绢条兜住下巴并固定在头顶，约半小时后取下，即可痊愈。
下巴脱臼源于肺肾两脏的虚损，以及元神的不足；或者是因谈笑时兴致高昂而忘记疲倦，导致一时之间元气不能接续所致。如果按照上述方法复位，必须注意避风，并迅速服用加味六君子汤，否则若外受风邪，必然导致痰涎壅盛、口眼歪斜，甚至风邪侵入脏腑，这种情况下十人中也难救活一人。（出自《集验》）
加味六君子汤（出自《集验》）。
人参、白术、白茯苓、半夏（各一钱五分）、天麻（经火煨制）、陈皮（各一钱）、僵蚕（酒炒后去除丝状物）、当归（各二钱）、附子（用滚开水浸泡后去皮和脐部，六分）、川芎（八分）、甘草（三分）。
灯心草四十根，生姜三片，加水煎煮后服用。
治疗下巴脱臼：口中含乌梅一二枚，将茶水从上往下倾倒冲洗。
治疗下巴脱臼：将乌梅捣碎制成饼状，塞满牙齿尽头处，待张口流涎后，随手将其托举复位。
陈实功说：人咬伤造成的危害，会使良肉受伤。因为属于阳明胃经所主的牙齿，脏腑多火多热。凡是食物经过此处，无不腐烂下咽，加上饮食炙烤之毒，无不侵袭人体。所以伤人后会引发肿胀，疼痛异常剧烈，流出臭脓并腐烂，疼痛彻连心髓，这是感受了牙齿中的毒素所致。在被咬后的第一天内，众人可用热尿浸泡患处，洗净牙齿残留的黄褐色瘀血，然后在咬孔上贴上蟾酥饼，再用膏药覆盖，之后渗出少量脓液便逐渐痊愈。如果在被咬初期没有采用这种方法，导致肿痛严重且肿胀明显者，也应先用童便洗净并擦干，用粗纸捻蘸取麻油，点燃后用烟焰熏烤肿痛部位，持续较长时间才停止，以此来解毒；然后仍将蟾酥条插入伤口，以太乙膏覆盖，等到消肿时更换玉红膏涂抹以促进肌肉生长、愈合伤口。（出自《正宗》）
Dislocation of the mandible (Luo Xia Ke) is caused by Qi deficiency, resulting in the inability to constrain the joint and orifice. The patient sits upright with a straight posture. Using both hands to support the lower jaw, the thumbs of the left and right hands are inserted into the mouth and placed on the molar teeth. The lower jaw is held firmly while force is applied downward toward the shoulders to open the joint, followed by pushing it upward toward the back of the head to reposition the joint. Subsequently, a silk strip is used to support the chin and fix it at the top of the head. After about half an hour, the strip is removed, and the condition is cured.
Mandibular dislocation arises from deficiency and damage in the Lung and Kidney organs, as well as insufficiency of the Primordial Spirit (Yuan Shen). It may also be caused by laughing or talking with high excitement until fatigue is forgotten, leading to a temporary failure of Yuan Qi to connect continuously. If reduced according to the method, one must avoid wind and quickly take Jiawei Liujunzi Tang (Modified Six Gentlemen Decoction); otherwise, if external Wind pathogen invades, it will inevitably lead to excessive phlegm-saliva accumulation and deviation of the mouth and eyes. If Wind enters the Zang-Fu organs, ten out of ten cases will not recover. (From *Ji Yan*)

Renshen (Ginseng Radix et Rhizoma), Baizhu (Atractylodis Macrocephalae Rhizoma), Baifuling (Poria), Banxia (Pinelliae Tuber) (each 1.5 qian); Tianma (Gastrodiae Rhizoma) (fire-roasted), Chenpi (Citri Reticulatae Pericarpium) (each 1 qian); Jiangcan (Bombyx Batryticatus) (wine-fried, remove silk), Danggui (Angelicae Sinensis Radix) (each 2 qian); Fuzi (Aconiti Lateralis Radix Praeparata) (soaked in boiling water, peel skin and remove umbilicus, 6 fen); Chuanxiong (Ligustici Chuanxiong Rhizoma) (8 fen); Gancao (Glycyrrhizae Radix et Rhizoma) (3 fen).

For mandibular dislocation: Hold one or two Wumei (Mume Fructus) in the mouth, and pour tea over them from above.
For mandibular dislocation: Crush Wumei (Mume Fructus) and make it into a cake, stuff it into the very end of the teeth. When the mouth opens and saliva flows, manually lift and reduce the jaw.
Chen Shigong said: Injuries caused by human bites result in damage to healthy flesh. Since the teeth belong to the Yangming Stomach Meridian, the internal organs often contain much Fire and Heat. Any food passing through here inevitably rots before being swallowed. Furthermore, toxins from roasted and grilled foods inevitably invade the body. Thus, injuries cause swelling with abnormal pain, foul pus discharge, and rotting; the pain penetrates to the heart. This is due to receiving the toxicity of the teeth. Within one day of the initial bite, people soak the injured area in hot urine, clean off the yellowish blood stasis from the teeth, and apply a Chan Su (Toad Venom) cake on the bite wound, covering it with plaster. As slight pus exudes later, gradual healing occurs. If this method was not used initially, causing severe swelling and pain, first clean and dry the area with child's urine. Then, roll coarse paper into a wick, dip it in Mazhongyou (Sesame Oil), light it, and use the smoke flame to fumigate the swollen and painful area for a long time to resolve the toxicity. Insert Chan Su strips into the wound, cover with Taiyi Gao (Taiyi Plaster), and when the swelling subsides, switch to Yuhong Gao (Jade Red Plaster) to rub and promote flesh growth and wound closure.
