凡人齿缝中出血，只以烧盐、灶突墨二物研匀，临卧擦牙漱口良。
盐胜血，故用烧盐；血得黑则止，故用灶突黑。
草乌 荜茇（各半两） 川椒 细辛（各二两）
《本事方》云∶四件共为细末，每用少许，以针揩在患牙内外，如此数次，其牙自伤，
则易
《本事方》云∶一士人夜归，其妻熟寝，士人撼之，妻问何事，不答。又撼之，其妻惊
视之，舌肿已满口，不能出声。急访医，得一叟，负囊而至，用药掺之，比晓复旧，问之，
乃蒲黄一物。昆谓《内经》曰∶热胜则肿。此必心脾之火并于舌，故令肿而满口。蒲黄性寒，
能
《良方》云∶一士人无故舌出血，仍有小窍，医者不晓何疾，炒槐花为末，掺之而愈。
昆谓诸见血皆是火证，槐花能疗血中之热，故愈。
热证多舌出。有病愈而舌不能入者，以冰片分许，末其舌上则入。所以舌出者，热实
于内，而欲吐舌泄气也；所以不能入者，邪气久居，舌强而不柔和也。冰片味辛热而气清香，
可以利窍，可以柔筋，可以泄气，故得之而舌入矣。
有人舌肿舒退场门外，无敢医者。一村人云∶偶有此药，归而取至，乃二纸拈。以灯烧之，
取烟熏，随即消缩。众问其方，村人曰∶吾家旧有一牛，亦舌肿胀退场门，人教以蓖麻油蘸纸
作拈，烧烟熏之而愈，因以治人亦验。昆谓舌肿舒退场门外，经所谓热胜则肿也。然舌者心之
苗，又脾之经络连舌本散舌下，其热当责于心脾二经。《本草》云∶蓖麻主浮肿恶气，取油
涂之。叶主风肿不仁，捣汁敷之，则其能解风肿内热也可知矣。然用其烟，犹有妙义。烟乃
轻清之物，一入其口，呼吸传变，可使径达心脾，匪微治标，亦可疗本。村人用之而不达其
理，斯其所以为村人；医者闻之而不察其理，则亦村人而已矣。
凡是牙齿缝隙中出血，只需将烧过的盐和灶膛里的烟墨这两种东西研成均匀的粉末，在临睡前用来擦牙并漱口，效果很好。
盐能克制血（中医认为咸味入肾，水克火，血属火，故盐胜血），所以使用烧过的盐；血液遇到黑色就能停止流动，所以使用灶膛里的黑墨。
草乌、荜茇（各半两）、川椒、细辛（各二两）。
《本事方》记载：将这四味药共同研磨成细末，每次取少量，用针蘸着涂抹在患牙的内侧和外侧，如此操作几次，牙齿自然松动脱落，然后就容易拔除了。
《本事方》记载：有一位读书人夜间回家，他的妻子睡得很熟，读书人摇醒她，妻子问有什么事，他不回答。又摇了几下，妻子惊醒看着他，发现舌头肿胀充满了整个口腔，无法发出声音。急忙寻找医生，遇到一位老者，背着药囊来到，用药粉撒在舌上，等到天亮时恢复如初。询问所用的药物，原来只是蒲黄一味药。我认为《内经》说：热邪亢盛就会导致肿胀。这一定是心脾之火合并于舌部，所以导致舌头肿胀充满口腔。蒲黄性寒，能够……
《良方》记载：有一位读书人无缘无故舌头出血，且仍有小孔，医生不知道是什么病，将槐花炒焦后研成粉末，撒在患处而痊愈。我认为凡是出现出血症状都属于火证，槐花能够治疗血中的热邪，所以痊愈了。
热证多表现为舌头伸出。有的病愈后舌头不能缩回口中，用少许冰片研成末涂在舌上，舌头就能缩回。之所以舌头伸出，是因为体内实热，想要吐出舌头来泄气；之所以不能缩回，是因为邪气久留，导致舌体僵硬而不柔和。冰片味道辛热而气味清香，可以通利窍道，可以柔润筋脉，可以泄除热气，所以用了它舌头就能缩回了。
有人舌头肿胀伸出场外门外，没有人敢医治。一个村民说：我偶然有这个药，回去取来，是两张纸捻成的条状物。用灯点燃，取烟雾熏烤，随即就消退缩小了。众人询问这个方子，村民说：我家以前有一头牛，也是舌头肿胀伸出场门，有人教他用蓖麻油蘸纸做成捻子，燃烧冒烟熏烤而痊愈，因此用来治人也有效。我认为舌头肿胀伸出场门外，就是经书所说的热邪亢盛导致肿胀。然而舌为心之苗窍，又是脾的经络连接舌根散布于舌下，其热邪应当归责于心脾两条经脉。《本草》记载：蓖麻主治浮肿恶气，取油涂抹。蓖麻叶主治风肿麻木，捣汁敷用，那么它能解除风肿和内热的道理也就知道了。然而使用它的烟雾，还有更精妙的意义。烟雾是轻清之物，一进入口腔，通过呼吸传导变化，可以使药力直达心脾，不仅仅是轻微地治疗表象，也可以治疗根本。村民使用了它却不明白其中的道理，这就是他被称为村民的原因；医生听到了却不考察其中的道理，那也只不过是个村民罢了。
Whenever bleeding occurs from the interdental spaces, simply grind together calcined salt (Yan, Salt) and soot from the chimney flue (Zaotu Mo, Chimney Soot) into a uniform powder. Apply this to brush the teeth and rinse the mouth before going to bed; it is effective.
Salt overcomes blood (in TCM theory, the salty flavor enters the Kidney channel; Water overcomes Fire, and Blood belongs to Fire, hence Salt overcomes Blood); therefore, calcined salt is used. Blood stops flowing when it encounters blackness; therefore, the black soot from the flue is used.
Caowu (Aconiti Kusnezoffii Radix), Bibo (Long Pepper Fruit), each half tael; Chuanjiao (Sichuan Pepper), Xixin (Asarum Root), each two taels.
The *Ben Shi Fang* records: Grind these four ingredients together into a fine powder. Use a small amount each time, apply it to the inner and outer surfaces of the affected tooth using an acupuncture needle. After repeating this several times, the tooth will naturally loosen and become easy to extract.
The *Ben Shi Fang* records: A scholar returned home at night. His wife was sleeping soundly. He shook her awake. When she asked what was wrong, he did not answer. He shook her again. Startled, she looked at him and found her tongue swollen, filling her entire mouth, rendering her unable to speak. They urgently sought a doctor and met an old man who arrived carrying a medicine bag. He applied powdered medicine to the tongue, and by dawn, it had returned to normal. Upon inquiry, the medicine used was merely Puhuang (Lygodii Spora). I hold that the *Neijing* states: "Excessive heat leads to swelling." This must be due to the fire of the Heart and Spleen merging in the tongue, causing it to swell and fill the mouth. Puhuang is cold in nature and can...
The *Liang Fang* records: A scholar suddenly experienced bleeding from his tongue, with small holes remaining. The physician did not understand the disease. He roasted Sophora flower (Huaihua, Sophorae Flos) until charred, ground it into powder, and applied it to the lesion, resulting in a cure. I maintain that all manifestations of bleeding are heat syndromes. Huaihua can treat heat within the blood, which is why the patient recovered.
Heat syndromes often present with protrusion of the tongue. In cases where the tongue cannot retract after recovery, applying a small amount of Bingpian (Borneol) as a powder on the tongue allows it to retract. The reason for tongue protrusion is excessive internal heat, leading to an attempt to vent qi by sticking out the tongue. The reason for inability to retract is that pathogenic factors have resided for a long time, causing the tongue to become stiff and inflexible. Bingpian has a pungent and hot taste with a clear fragrance. It can open orifices, soften sinews, and vent heat. Therefore, upon its use, the tongue retracts.
There was a case where a person's tongue was swollen and protruding outside the gate, and no one dared to treat it. A villager said, "I happen to have this medicine." He retrieved it, which consisted of two paper twists. Lit with a lamp, the smoke was used to fumigate the area, and the swelling immediately subsided. When asked about the prescription, the villager said, "My family once had an ox whose tongue was also swollen and protruding outside the gate. Someone taught us to dip paper in castor oil, make it into a twist, burn it to produce smoke, and fumigate the area, which cured the ox. Thus, using it on humans also proved effective." I hold that tongue swelling protruding outside the gate corresponds to the classic saying: "Excessive heat leads to swelling." However, the tongue is the sprout of the Heart, and the meridians of the Spleen connect to the root of the tongue and spread beneath it. The heat should be attributed to the Heart and Spleen meridians. The *Bencao* records: Castor seed treats edema and foul qi; apply the oil topically. Castor leaf treats wind-induced swelling and numbness; crush and apply the juice. Thus, its ability to resolve wind-swelling and internal heat is evident. However, the use of its smoke holds profound significance. Smoke is a light and pure substance. Once entering the mouth, through respiration and transmission, it can reach the Heart and Spleen directly. It not only mildly treats the symptoms but also addresses the root cause. The villager used it without understanding the principle, which is why he remains a villager. Physicians who hear of it without investigating the principle are likewise no better than villagers.
