卤石是产自盐产地、未经炼制的矿石。颜色混杂红黄，有毒，不可使用。初次炼制称为朴硝，再次炼制有的变成芒硝，有的变成马牙硝。内服宜用芒硝和马牙硝，若用朴硝则不太适宜。
主治功效：去除肠胃中的积聚物，攻坚散结，疏通经脉，通利大小便，治疗月经闭阻，五淋（五种淋证），消散恶血，清除壅滞之热，治疗黄疸。孕妇忌用。
碧雪方：朴硝、芒硝、马牙硝、硝石、石膏、寒水石，各取一两，经水飞法处理后，甘草一两。加水一斗，煎煮至剩余五升。加入上述药物共同煎煮，不停手搅拌使其熔化得当。加入青黛一两混合均匀，倒入盆中，过夜后结成雪状。研成粉末，或含化咽下，或吹敷患处，或用水调服二三钱。若想通利大便，用热水送服一两。治疗一切积热、流行性时疫疾病、发狂、神志昏乱、咽喉肿塞、口舌生疮、大小便不通、腹中痞块。用朴硝一两，独蒜一个，大黄末八分，捣制成饼，贴于患处，以病灶消退为度。

Halite is an ore produced in salt-producing areas that has not been refined. Its color is mixed with red and yellow; it is toxic and should not be used. The first refinement yields Puxiao (Mirabilite). Further refinement may produce Mangxiao (Glauber's Salt) or Mayaxiao (Horse-tooth Glauber's Salt). For internal use, Mangxiao and Mayaxiao are preferred; using Puxiao is less suitable.
Indications: Eliminates accumulations in the gastrointestinal tract, breaks down hard masses and resolves stagnation, unblocks meridians, promotes urination and defecation, treats amenorrhea, five types of strangury (Wulin), dissipates bad blood, clears obstructive heat, and treats jaundice. Contraindicated in pregnancy.
Bixue Formula: Puxiao (Mirabilite), Mangxiao (Glauber's Salt), Mayaxiao (Horse-tooth Glauber's Salt), Xiaoshi (Niter), Shigao (Gypsum Fibrosum), Hanshuishi (Aqua Calcitae), each one jin (approx. 500g), processed by water-flying method; Gancao (Licorice Root) one jin. Add one dou (approx. 10 liters) of water, decoct until five sheng (approx. 5 liters) remain. Add the aforementioned herbs and continue decocting, stirring constantly until properly melted. Add Qingdai (Indigo Naturalis) one jin and mix evenly. Pour into a basin and leave overnight until it crystallizes like snow. Grind into powder. It can be held in the mouth to swallow, blown onto affected areas, or taken orally mixed with water, two to three qian (approx. 6-9g). To promote bowel movement, take one liang (approx. 30g) with hot water. Treats all forms of accumulated heat, epidemic febrile diseases, mania, confusion, swelling and obstruction of the throat, sores on the mouth and tongue, and blockage of urination and defecation. For abdominal masses, use Puxiao (Mirabilite) one liang (approx. 30g), one bulb of garlic, and Dahuang (Rhubarb Root) powder eight fen (approx. 2.4g). Pound into a cake and apply to the affected area until resolved.
For difficult labor and retained dead fetus: Take Mangxiao (Glauber's Salt) powder two qian (approx. 6g), warmed with urine from a healthy boy. This is remarkably effective. For poisoning from taking mineral pills (Rushi), presenting with chest irritability and heat accumulation: Take Mangxiao (Glauber's Salt) one qian (approx. 3g), mixed with honey water. Take three times daily.
For pediatric food stagnation: Use Aiye (Mugwort Leaf) pounded soft, mix with Puxiao (Mirabilite) evenly, apply to the hard area of the abdomen with cloth, wrap it up to let the child sleep, and remove the next morning.
Preparation Method: Use ten jin (approx. 5 kg) of pure white Puxiao (Mirabilite) and one shi (approx. 100 liters) of flowing water. Boil to dissolve, filter out residues, and expose to the open air overnight. Remove the water to obtain the crystal. For every ten dou (approx. 100 liters volume equivalent) of crystal, add one jin (approx. 500g) of Luobo (Radish), sliced, and boil together until cooked. Filter cleanly and expose to the open air overnight again. Take out. For every jin (approx. 500g) of crystal, boil with one liang (approx. 30g) of Gancao (Licorice Root), remove residues, and expose to the open air overnight once more. Place in a large clay jar, seal tightly with salt mud to a thickness of half cun (approx. 1.5 cm), without covering the mouth. Place in a stove, heating first with mild fire (Wenhuo) then strong fire (Wuhuo). Once boiling stabilizes, cover with a tile and reseal as before. Apply fierce fire. After cooling for one fushi (approx. 2 hours), remove. Place on the ground over paper, cover with a basin for three days to eliminate residual fire energy. Grind into powder. For every jin (approx. 500g) of powder, add one liang (approx. 30g) of raw Gancao (Licorice Root) powder and one liang (approx. 30g) of honey-fried Gancao (Licorice Root) powder, mix evenly, and store in a bottle.
Indications: Heart heat with irritability, accumulations in the five zang organs, promoting urination and defecation. Compared to Mangxiao (Glauber's Salt), this preparation has fewer adverse effects and is most suitable for attacking and resolving accumulations.
