华佗内科神方
伤寒病刚得病一天，邪气在皮肤表层，应当使用膏药按摩，并用火灸治疗，即可痊愈。如果病情没有解除，到了第二天邪气在肌肤层，可以依法进行针刺，服用解肌散以发汗，汗出后病情即愈。如果病情仍未解除，到了第三天邪气在肌肉层，再次发汗即可痊愈。如果病情仍然没有解除，就停止不要再发汗了。到了第四天邪气在胸中，适宜服用藜芦丸，引起轻微呕吐即可痊愈。如果病人更加困顿，藜芦丸不能引起呕吐的，服用小豆瓜蒂散，通过催吐即可痊愈。观察病情尚未清醒的，再用另一种方法针刺。第五天邪气在腹部，第六天进入胃腑，进入胃腑就可以使用泻下法治疗。另外，伤寒初起时，用柴胡、白芍、茯苓、甘草、桂枝、麻黄各一钱、当归二钱，陈皮五分，水煎服效果极佳。
凡是患伤寒，第一天到第二天没有出汗的，适宜使用：
葛根半斤 乌梅十四枚 葱白一握 豆豉一升（用绵布包裹）
用水九升，煮取三升药液，分三次服用。第一次服用后立即严密覆盖身体以获取汗液，汗出后扑上爽身粉。
大黄四两 厚朴二两（炙烤） 枳实三枚（炙烤）
用水四升，煮取一升二合药液，去掉药渣，分两次温服。如果第一次服药后大便通畅，谵语停止，就不要再服用了。
凡是伤寒热势极盛导致发狂，惊悸恍惚。可以紧急使用：
石膏二钱 黄连一钱
研成粉末，用甘草煎汤放冷后送服，有疗效。
伤寒结胸证，是指热毒之气结聚在心胸部位。这是由于病发于阳经而过早使用泻下法，热气乘虚而入导致痞塞结聚不散。按压胸部疼痛，寸脉浮，关脉沉就是这种病症的表现。可以使用：
蜀地大黄半斤 葶苈子半升（炒制） 杏仁半升（去皮尖，炒至赤黑色） 芒硝半升
以上四味药，将其中两味捣碎过筛，杏仁与芒硝研磨如泥状，混合均匀制成丸药，大小如弹子。每次服用一丸，用甘遂末一钱匕，白蜜一两，水二升共同煮取一升药液，温热一次服下，一夜之后自然排泄。如果未排泄，再服用以促使排泄为要。或者使用栝蒌一枚（捶碎），甘草一钱，共同煎服，效果极其神奇。
Hua Tuo's Internal Medicine Divine Prescription
On the first day of contracting Shanghan (Cold Damage), when the pathogen is in the skin, one should apply medicated ointment with massage and use moxibustion; this will lead to recovery. If there is no improvement, on the second day when the pathogen is in the flesh and skin, acupuncture may be performed according to protocol, and Jieji San (Muscle-Releasing Powder) should be taken to induce sweating; recovery follows once sweat appears. If there is still no improvement, on the third day when the pathogen is in the muscles, inducing sweat again will lead to recovery. If it remains unresolved, do not induce sweat again. On the fourth day, when the pathogen is in the chest, Lili Wan (Veratrum Pill) is suitable; mild vomiting leads to recovery. If the patient becomes more distressed and Lili Wan fails to induce vomiting, Xiaodou Guiti San (Adzuki Bean and Melon Seed Dispersant) should be taken to induce vomiting for recovery. Observe if the illness has not cleared; if so, apply another method of acupuncture. On the fifth day, the pathogen is in the abdomen; on the sixth day, it enters the Stomach (Zang-Fu organ). Once it enters the Stomach, purgation can be used. Additionally, at the onset of Shanghan, using Chaihu (Bupleuri Radix), Baishao (Paeoniae Radix Alba), Fuling (Poria), Gancao (Glycyrrhizae Radix et Rhizoma), Guizhi (Cinnamomi Ramulus), Mahuang (Ephedrae Herba) each at one qian, Danggui (Angelicae Sinensis Radix) at two qian, and Chenpi (Citri Reticulatae Pericarpium) at five fen, decocted in water and taken orally, is highly effective.
For those suffering from Shanghan who have not sweated within the first two days, the following is suitable:
Ge Gen (Puerariae Lobatae Radix) half jin, Wumei (Mume Fructus) fourteen pieces, Congbai (Allii Fistulosi Bulbus) one handful, Douchi (Sojae Semen Praeparatum) one sheng (wrapped in cotton cloth).
Boil in nine sheng of water until three sheng remain. Divide into three doses. After the first dose, cover densely to induce sweating; apply powder after sweating occurs.
Dahuang (Rhei Radix et Rhizoma) four liang, Houpo (Magnoliae Officinalis Cortex) two liang (roasted), Zhishi (Aurantii Fructus Immaturus) three pieces (roasted).
Boil in four sheng of water until one sheng and two he remain. Remove dregs and take warm in two divided doses. If bowel movement is achieved after the first dose and delirium ceases, do not take further.
For cases where Shanghan heat reaches an extreme causing mania, palpitations, and confusion, urgently use:
Shigao (Gypsum Fibrosum) two qian, Huanglian (Coptidis Rhizoma) one qian.
Grind into powder, decoct Gancao (Glycyrrhizae Radix et Rhizoma) in water, let cool, and take orally; this is effective.
Jietong (Chest Binding) in Shanghan refers to the accumulation of toxic heat in the heart and chest region. This arises because the disease originated in the Yang aspect but was treated too early with purgatives, allowing heat to enter the deficiency and cause persistent stagnation. Tenderness upon pressure, a floating pulse at the Cun position, and a sinking pulse at the Guan position are indicative. The following may be used:
Shu Dahuang (Rhei Radix et Rhizoma) half jin, Tinglizi (Descurainiae Semen seu Lepidii Semen) half sheng (fried), Xingren (Armeniacae Semen Amarum) half sheng (skin and tip removed, fried until dark red-black), Mangxiao (Natrii Sulfas) half sheng.
Crush and sieve two of the four ingredients. Grind Xingren and Mangxiao into a paste, mix uniformly, and form pills the size of a bullet. Take one pill per dose with Gansui (Kansui Radix) powder one qian-bi, white honey one liang, and two sheng of water. Boil together until one sheng remains, take warm in one dose. Natural evacuation will occur overnight. If no evacuation occurs, administer again to ensure evacuation. Alternatively, use one Gualou (Trichosanthis Fructus) (crushed) and one qian of Gancao (Glycyrrhizae Radix et Rhizoma), decocted together and taken orally; this is extremely effective.
