庚生按∶此方似太猛峻，用时须审病患虚实为妥，予尝以一方治久嗽颇效，方附后∶

即愈。寻常嗽血妄行，每服一匙可也，此药绝妙。
庚生按∶此许学士方也，专治劳瘵吐血肺损及血妄行等症。许公盛推其妙，称为神授云。
剪草疑即茜草，本草虽载其名，只云生山泽间，苦凉无毒，未明形状。《本事方》谓剪草即
茜草，婺州台州皆有之，人鲜知者，细绎方意，盖即茹芦也。
治疗久咳和突发剧烈咳嗽。取雄黄一两研成粉末，用泥土密封固定并晾干，用水调和赤石脂封口，再用泥土封好等待干燥，放置在地面上，周围堆聚十斤炭火进行煅烧。等到火势减弱三分之一时，撤去火源，待冷却后取出，药色如镜面般光亮呈红色，在瓷钵内细细研磨，制成像米粒大小的蒸饼丸剂。每次服用三丸或五丸，用甘草汤送服，服药后稍作睡眠，过一段时间后即可痊愈。
庚生按语：这个方子似乎过于猛烈峻急，使用时必须仔细审察病患的虚实状况才稳妥。我曾经用一个方子治疗久咳非常有效，方子附在后面：
取香橼一枚，去掉果核切片，与清酒一起捣烂，放入砂罐中，用小火慢慢煮制，从黄昏一直煮到五更天为止。用药蜜拌匀，唤醒病患，嘱咐他们用勺子挑着服用，服完后再次睡一会儿，一次服用即可痊愈。
另一个方子：取一束向南生长的柔嫩桑枝，折断成寸长的小段；放入砂罐中，加入五碗水，煎煮至剩下一碗水，饮用也有效。
专门治疗血症。取剪草一斤，洗净晒干后研成粉末，加入生蜂蜜二斤，调和成膏状，用容器盛装，不得接触铁器。每天蒸晒一次，经过九次蒸、九次晒后停止。病患在五更天时面向东方端坐，不说话，用勺子舀取四匙药粉食用，过一段时间后用稀薄的粟米饮压住药性。药物宜冷服，米饮也不要太热，服药后如果出现呕吐现象，都没有妨碍。对于久病导致肺损伤而咳血的情况，服用一次即可痊愈。对于普通的咳嗽出血、血液妄行的情况，每次服用一匙即可，此药绝妙。
庚生按语：这是许学士的方子，专门治疗劳瘵吐血、肺损伤以及血液妄行等症状。许公极力推崇其奇妙之处，称之为“神授”。
剪草怀疑就是茜草，本草书中虽然记载了它的名字，只说生长在山水之间，味苦、性凉、无毒，但没有明确描述其形状。《本事方》中说剪草就是茜草，婺州、台州都有出产，但人们很少知道。仔细推究方子的用意，大概就是指茹芦（即茜草）。
Treats chronic cough and sudden violent cough. Take one liang of Realgar (Xionghuang, 雄黄), grind it into powder, seal it with mud to dry, seal the opening with a paste made of water and Red Halloysite (Chishizhi, 赤石脂), then seal again with mud and wait for it to dry. Place it on the ground and surround it with ten jin of charcoal for calcination. When the fire has diminished by one-third, remove the heat source and wait for it to cool. Retrieve the substance, which should be bright red and glossy like a mirror surface. Grind it finely in a porcelain mortar and form pills the size of rice grains using steamed bread dough. Take three or five pills each time, swallowed with Licorice Root Decoction (Gancao Tang, 甘草汤). Sleep briefly after taking the medicine; recovery will occur after some time.
Geng Sheng notes: This formula seems too harsh and potent. It is advisable to carefully assess the patient's deficiency or excess patterns before use. I once used another formula to treat chronic cough with considerable efficacy, which is appended below:
Take one Citron (Xiangyuan, 香橼), remove the core and slice it. Pound it thoroughly with clear wine, place it in a clay pot, and simmer slowly over low heat from dusk until the fifth watch of the night. Mix well with honey, wake the patient, and instruct them to take it with a spoon. After ingestion, let them sleep for a short while; one dose results in a cure.
Another formula: Take a bundle of tender mulberry branches facing south, break them into inch-long pieces. Place them in a clay pot, add five bowls of water, and decoct until only one bowl remains. Drinking this is also effective.
Specially treats blood disorders. Take one jin of Jiancao (Jiancao, 剪草), wash it clean, dry it in the sun, and grind it into powder. Add two jin of raw honey and mix into a paste. Store in a container, ensuring no contact with iron vessels. Steam and sun-dry once daily, repeating the process nine times (nine steamings and nine dryings) before stopping. At the fifth watch, the patient sits facing east, remaining silent. Take four spoonfuls of the medicine with a spoon, and after a while, suppress the medication with thin millet drink. The medicine should be taken cold, and the millet drink should not be too hot. Vomiting or retching after ingestion is acceptable. For chronic lung damage causing hemoptysis, one dose brings a cure. For ordinary coughing up of blood or spontaneous bleeding, one spoonful per dose is sufficient. This medicine is excellent.
Geng Sheng notes: This is a formula by Academician Xu, specifically treating tuberculosis with hematemesis, lung injury, and spontaneous bleeding. Lord Xu highly praised its efficacy, calling it "divinely bestowed."
Jiancao is suspected to be Rubia cordifolia (Qiancao, 茜草). Although Materia Medica records its name, stating it grows in mountains and marshes, is bitter, cool, non-toxic, and lacks a clear description of its shape, *Ben Shi Fang* states that Jiancao is Qiancao, found in Wuzhou and Taizhou, though rarely known by people. Careful analysis of the formula's intent suggests it refers to Ru Lu (which is Qiancao).
