【紫雪丹方】
石膏、寒水石、滑石（各八两）、升麻、犀角片、羚羊片（各一两）、元参（二两）、甘草（八钱）、沉香屑、木香屑（各五钱）。
以上药材用水煎煮，取浓汁，滤去药渣，投入经过提纯的朴硝三两六钱，用小火慢煎，等到水分将尽、药液即将凝结时，加入朱砂、冰片各三钱，金箔一百张，研磨细碎并混合均匀，收藏备用。
此方治疗重舌（舌下肿胀如双舌）和木舌（舌体僵硬不灵），无论是口舌生疮，外敷或内服，效果都很好。（景华按：这就是《太平惠民和剂局方》中的紫雪丹，只是制作方法略有不同。）【谔按：此方用于治疗热邪内陷导致的痉厥（抽搐昏迷），使用此方可使病情缓解。如果是热症偏向风邪者，使用至宝丹。热邪蒙蔽心包出现胡言乱语者，使用牛黄清心丸。如果是痰浊蒙蔽、气机闭塞，则使用苏合香丸。一种病症对应一方，为什么现在的人一遇到闭证厥逆，就手忙脚乱，恐吓病人家属，不问病症是痰、是风、是气还是热，胡乱开具清心丸、至宝丹、紫雪丹，误人性命，差之毫厘谬以千里，能不谨慎吗！】

【砂散方】
番砂、人中白（各五分）、瓦上青苔、溏鸡矢（稀鸡粪）、瓦松（即瓦花，各一钱）。
以上药材用两个银罐子，将药装入罐内，上面用一个空罐子对口盖住，用盐泥封固，用炭火煅烧至通红，燃烧三炷香的时间为度，冷却后开罐，取出药物，加入麝香、冰片各一分，研磨细碎后使用。此方专门治疗舌菌（舌部恶性肿瘤），用磁针刺破患处，将此药点上，再用蒲黄覆盖。该病症最为凶险，初起时像头顶疼痛且无皮肤保护，早晨轻晚上重，用此药点涂，自然会消退缩小。如果延误治疗，导致舌头腐烂穿透面颊，极为凶险，百无一活。
[Formula for Zixue Dan (Purple Snow Pill)]
Shigao (Gypsum Fibrosum), Shuingshi (Halloysitum Rubrum), Huashi (Talcum) (each 8 liang), Shengma (Cimicifugae Rhizoma), Xijiao Pian (Rhinocerotis Cornu Slice), Lingyang Pian (Saiga Tataricae Cornu Slice) (each 1 liang), Yuan Shen (Scrophulariae Radix) (2 liang), Gancao (Glycyrrhizae Radix et Rhizoma) (8 qian), Chenxiang Xie (Aquilariae Lignum Resinatum), Muxiang Xie (Aucklandiae Radix) (each 5 qian).
Decoct the above herbs in water, obtain a concentrated decoction, filter out the dregs, add 3 liang 6 qian of purified Puxiao (Natrii Sulfas), and simmer slowly over a gentle fire. When the water vapor is nearly exhausted and the liquid is about to coagulate, add Zhusha (Cinnabaris) and Bingpian (Borneolum Syntheticum), each 3 qian, and 100 sheets of Jinbo (Gold Leaf). Grind finely and mix uniformly, then store for use.
This formula treats Chongshe (Re-she: swelling of the tongue resembling double tongues) and Mushe (Wooden Tongue: stiffness of the tongue). Whether applied externally or taken internally for sores on the mouth and tongue, it is effective. (Jinghua notes: This is Zixue from the *Ju Fang* [Formulas of the Bureau], only the preparation method differs slightly.) [E notes: This formula treats Jingjue (Spasm and coma) caused by the internal collapse of heat syndromes; using this can open the blockage. If the heat syndrome leans towards wind, use Zhibao Dan (Treasure of Life Pill). If heat confuses the Pericardium manifesting as delirious speech, use Niuhuang Qingxin Wan (Calculus Bovis Clearing Heart Pill). If it is phlegm confusing and Qi closing, use Suhexiang Wan (Styrax Pill). Each syndrome has its specific formula. Why do people today, upon encountering Bi Jue (obstruction and coma), panic and frighten the patient's family, without asking whether the syndrome is due to phlegm, wind, Qi, or heat, and indiscriminately prescribe Qingxin Wan, Zhibao Dan, or Zixue Dan, thereby costing lives? A slight error leads to a huge discrepancy; one must be cautious!]
Originally named Qingxi Misuan Beiting Dan.
[Formula for San San]
Fansha (Antimony Trioxide), Renzhongbai (Urina Seca) (each 5 fen), Washang Qingtai (Green Moss on Roof Tiles), Tang Jishi (Fresh Chicken Droppings), Wasong (Sedum sarmentosum / Tile Pine) (each 1 qian).
Place the above herbs into two silver jars. Cover one jar with an empty jar mouth-to-mouth, seal tightly with salt mud, and calcine over charcoal fire until red hot. The duration should be three incense sticks. After cooling, open the jars, remove the medicine, add Shexiang (Moschus) and Bingpian (Borneolum Syntheticum), each 1 fen, grind finely, and use. This formula is specifically for Shejun (Tongue Fungus: malignant tumor of the tongue). Prick the lesion with a magnetized needle, apply this powder, and cover it with Huyang (Pollen Typhae). This condition is extremely malignant. In the early stage, it resembles pain on the head without skin protection, being lighter in the morning and heavier in the evening. Applying this medication will naturally cause it to shrink and subside. If treatment is delayed, leading to tongue rot penetrating the cheek, it is extremely ominous, with no survivors out of a hundred.
