戴人在西华，寄于夏官人宅。忽项上病一疮，状如白头，疮肿根红硬，以其微小
，不虑也。忽遇一故人见邀，以羊羔酒饮，鸡鱼醢蒜皆在焉。戴人以其故旧，不能辞，又忘
其禁忌。是夜疮疼痛不可忍，项肿及头，口发狂言，因见鬼神。夏君甚惧，欲报其家。戴人
笑曰∶请无虑，来日当平。乃以酒调通经散六、七钱，下舟车丸百余粒，次以热面羹投之。
上涌下泄，一时齐作，合去半盆。明日日中，疮肿已平。一、二日，肿消而愈。夏君见，大奇之。
麻先生妻，病代指痛，不可忍。酒调通经散一钱，半夜大吐，吐毕而痛减。余因
叹曰∶向见陈五曾病此，医以为小虫伤，或以草上有毒物，手因触之。迁延数月，脓尽方已。以今日观之，可以大笑。
一妇人病瘰 ，延及胸臆，皆成大疮，相连无好皮肉，求戴人疗之。戴人曰∶火
淫所胜，治以咸寒。命以沧盐吐之，一吐而着痂。次用凉膈散、解毒汤等剂，皮肉乃复如初。
一妇人病咽喉肿塞，浆粥不下，数日肿不退，药既难下，针亦无功。戴人以当归、
荆芥、甘草煎，使热漱之，以冷水拔其两手。不及五、六日，痛减肿消，饮食如故。咽喉之
病甚急，不可妄用针药。
南邻朱老翁，年六十余岁，身热数日不已，舌根肿起，和舌尖亦肿，肿至满口，
比元舌大二倍。一外科以燔针刺其舌下两旁廉泉穴，病势转凶，将至颠
。戴人曰∶血实者宜决之。以 针磨
令锋极尖，轻砭之，日砭八、九次，血出约一、二盏，如此者三次，渐而血少痛减肿消。夫
舌者，心之外候也。心主血，故血出则愈。又曰∶诸痛痒疮疡，皆属心火。燔针艾火，是何义也？
When Dai Ren was in Xihua, he stayed at the residence of Official Xia. Suddenly, a sore appeared on his neck, resembling a "white-headed" sore (a type of superficial abscess with a white head), with a red and hard base. Due to its small size, he did not worry about it. Suddenly, an old friend invited him to a banquet where mutton lamb wine, chicken, fish, meat sauce, and garlic were served. Because of their past friendship, Dai Ren could not refuse, and he forgot the dietary contraindications. That night, the pain from the sore became unbearable, swelling spread from the neck to the head, he spoke deliriously, and even saw ghosts and spirits. Master Xia was very frightened and wanted to inform Dai Ren's family. Dai Ren laughed and said, "Please do not worry; it will be flat tomorrow." He then mixed Tongjing San (Unblocking Meridian Powder) with wine, administering 6-7 qian, followed by over 100 pills of Zhouche Wan (Boat and Cart Pill). Next, he had him drink hot noodle soup to induce vomiting. Both upper vomiting and lower purging occurred simultaneously, expelling half a basin of waste. By noon the next day, the sore and swelling had flattened. Within one or two days, the swelling subsided, and he recovered. Master Xia was greatly amazed upon seeing this.
The wife of Mr. Ma suffered from Daizhi Tong (painful inflammation of the fingertip), which was unbearable. One qian of Tongjing San (Unblocking Meridian Powder) was taken with wine. She vomited heavily at midnight, and the pain subsided after vomiting. I sighed and said, "Previously, I saw Chen Wu suffer from this condition. Physicians attributed it to insect bites or contact with toxic substances on grass. The condition dragged on for months until the pus drained completely before healing. Looking at it today, it is laughable."
A woman suffered from Luoli (scrofula/neck lymph node tuberculosis), which extended to her chest and epigastrium, forming large sores with no healthy skin or flesh remaining between them. She sought treatment from Dai Ren. Dai Ren said, "This is caused by excessive Fire pathogen; it should be treated with Salty-Cold methods." He ordered the use of Cangyan (Blue Salt) to induce vomiting. After one episode of vomiting, scabs formed. Subsequently, using Liangge San (Cooling the Diaphragm Powder) and Jiedu Tang (Detoxifying Decoction), her skin and flesh returned to normal.
Another woman suffered from severe throat swelling and obstruction, unable to swallow liquids or porridge. The swelling persisted for several days despite medication being difficult to administer and acupuncture proving ineffective. Dai Ren prescribed a decoction of Danggui (Angelicae Sinensis Radix), Jingjie (Schizonepetae Herba), and Gancao (Glycyrrhizae Radix et Rhizoma) for the patient to gargle with while hot, and simultaneously applied cold water to draw out the blood from both hands. Within five or six days, the pain decreased, the swelling subsided, and her diet returned to normal. Throat diseases are extremely urgent; one must not recklessly use needles or drugs.
Old Man Zhu, a neighbor to the south, aged over sixty, had persistent fever for several days. His tongue root swelled up, and the tip also swelled, filling his entire mouth, becoming twice the size of his original tongue. A surgeon used a burning needle (red-hot needle) to puncture the Lianquan acupoint (CV23) on both sides under the tongue, but the condition worsened, nearly reaching the vertex (endangering life). Dai Ren said, "Where there is Blood excess, one should drain it." He sharpened a Pi needle (flat-bladed needle) to an extreme point and lightly pricked the tongue, doing so eight or nine times a day. Approximately one to two zhan of blood was discharged each time. This was repeated three times. Gradually, the blood loss decreased, pain subsided, and swelling resolved. The tongue is the external manifestation of the Heart. The Heart governs Blood; therefore, bleeding leads to recovery. It is also said, "All pain, itching, sores, and ulcers belong to Heart Fire." What is the rationale behind using burning needles and moxibustion?
