人有遍身发癞，皮浓而生疮，血出而如疥，或痛或痒，或干或湿，如虫非虫，
人以为湿热之留于皮肤也，孰知是气血不能周到滋润乎。世多以苦参煎汤或 、
白芷之类外治，而终无成效，正坐于气血之虚也。盖气血足则经络无闭塞之虞，气
血旺则毛窍无干枯之害。且气足血旺，则热散湿消，何至淤滞而不通散，结于皮肤
之外。故治癞之法，专以补气血为主，而佐之消湿散热之味。虽十载沉 ，尚可奏
功于旦夕，矧目前之近癞乎。方用扫癞丹∶
黄 （三两） 当归（二两） 防风（二钱） 茯苓（一两） 白术（一两） 生甘草（三钱）
麦冬（一两） 金银花（二两） 芍药（一两） 川芎（五钱） 熟地（一两） 山萸（五钱） 元参（一两）
荆芥（三钱） 天花粉（三钱） 水煎服。二剂而皮色润，又服二剂而干燥解，连服十剂全愈。
此方大补气血，无异枯涸之田，一旦忽逢霖雨，生机勃勃，又何至有尘埃之敝野哉。
人之腿受官刑，皮肉腐烂，死血未散，疼痛呼号，似宜用膏药、末药外治为佳。
然而受刑深重，不急内消，专恃外治，则逍遥膜外，安能卫心，使恶血之不相犯乎。
此内治之断不宜迟也。然而，世人外治之方多有神奇，而内治之方绝无应验，往往
有一时心乱而死者。虽犯法遭刑，多缘恶积，保无受冤之屈棒乎。冤气在心，则肝
叶开张，肝气收敛，尤善引血入心，使无辜之人一旦轻死，疗治无法，是谁之愆。
铎求异人特传一方，一受官刑，实时煎服，断无性命之虞。服后，然后用膏药、末
药外治，内外夹攻，则疮口易愈矣。内治方名为卫心仙丹∶
大黄（三钱） 当归（一两） 红花（三钱） 桃仁（三十粒） 生地（一两） 丹皮（三钱）
木耳（三钱） 白芥子（二钱） 水煎服。一剂而恶血散矣，不必二剂也。然后以膏药贴之，
膏方名护心仙丹∶
大黄（一两） 没药（三钱） 乳香（三钱） 白蜡（一两） 松香（五钱） 骨碎补（五钱）
当归（一两） 三七根（三钱） 败龟板（一两） 麝香（五分） 各为细末，猪板油一两，将白蜡、
松香同猪油在铜锅内化开，后将各药末拌匀，为膏药。贴在伤处，外用油纸包裹，再用布缠
住。轻者一膏即痊，重者两膏足矣。夹棍伤重，大约不须四个，即可行步无虞矣。
此二方至神至奇，内方使恶血尽散，外方使死肉之速生，合而用之，又何至损人性命哉。
There are cases where a person develops scabies-like lesions all over the body, with thickened skin and sores that bleed like eczema or scabies. The symptoms may include pain or itching, dryness or dampness; it resembles insects but is not actually insects. People assume this is due to the retention of Damp-Heat (Shi Re) in the skin, but who would know that it is actually caused by Qi and Blood failing to circulate fully and nourish the body? In the world, many use decoctions of Sophora flavescens root (Kushen, 苦参) or external treatments with Angelica dahurica root (Baizhi, 白芷), etc., but ultimately achieve no effect. This is precisely due to the deficiency of Qi and Blood. When Qi and Blood are sufficient, there is no fear of meridian blockage; when Qi and Blood are vigorous, hair follicles do not suffer from dryness. Moreover, with sufficient Qi and abundant Blood, Heat dissipates and Dampness vanishes. How could stagnation occur, blocking flow and knotting outside the skin? Therefore, the method for treating scabies focuses primarily on tonifying Qi and Blood, assisted by herbs that eliminate Dampness and clear Heat. Even if the disease has persisted for ten years, efficacy can be achieved in a short time, let alone recent onset. The formula used is Sao Lai Dan (Scabies-Sweeping Elixir): Astragali Radix (Huangqi, 黄耆) 3 liang, Dang Gui (Angelica sinensis Radix) 2 liang, Fang Feng (Saposhnikoviae Radix) 2 qian, Poria (Fuling, 茯苓) 1 liang, Atractylodis Macrocephalae Rhizoma (Baizhu, 白术) 1 liang, Raw Glycyrrhizae Radix et Rhizoma (Sheng Gancao, 生甘草) 3 qian, Ophiopogonis Tuber (Maidong, 麦冬) 1 liang, Lonicerae Japonicae Flos (Jinyinhua, 金银花) 2 liang, Paeoniae Radix (Shaoyao, 芍药) 1 liang, Chuanxiong Rhizome (Chuanxiong, 川芎) 5 qian, Rehmanniae Radix Preparata (Shu Di, 熟地) 1 liang, Corni Fructus (Shanzhuyu, 山萸) 5 qian, Scrophulariae Radix (Xuanshen, 元参) 1 liang, Schizonepetae Spica (Jingjie, 荆芥) 3 qian, and Trichosanthis Radix (Tianhuafen, 天花粉) 3 qian. Decoct in water and take orally. After two doses, the skin color becomes moist; after another two doses, dryness resolves. Continuous administration for ten doses results in complete recovery. This formula greatly tonifies Qi and Blood, akin to a barren field suddenly receiving rain, becoming full of vitality, thus avoiding the desolation of dusty wastelands.
When a person’s legs suffer from official corporal punishment (caning), the skin and flesh rot, and stagnant blood remains unresolved, causing painful wailing. It seems appropriate to treat externally with plasters and powdered medicines. However, given the severity of the injury, if internal resolution is not prioritized and one relies solely on external treatment, the therapeutic effect remains superficial ("outside the membranes") and cannot protect the Heart, allowing evil blood to invade. Thus, internal treatment must not be delayed. Yet, worldly external formulas often appear miraculous, while internal ones rarely prove effective, leading patients to die from sudden mental agitation. Although those punished for crimes often accumulate evil deeds, are there no cases of unjust suffering? Resentful Qi stagnating in the Heart causes the Liver lobes to expand and Liver Qi to contract, particularly drawing blood into the Heart, causing innocent people to die prematurely. With no cure available, whose fault is this? I, Chen Shiduo, obtained a special transmission from an extraordinary person: upon receiving corporal punishment, decoct and take immediately, ensuring no danger to life. After taking the medicine, then apply external plasters and powders. Internal and external attacks combined will facilitate wound healing. The internal formula is named Wei Xin Xian Dan (Heart-Guarding Immortal Elixir): Rheum Palmatum Rhizome (Dahuang, 大黄) 3 qian, Dang Gui 1 liang, Carthami Flos (Honghua, 红花) 3 qian, Persicae Semen (Taoren, 桃仁) 30 grains, Rehmanniae Radix (Shengdi, 生地) 1 liang, Moutan Cortex (Danpi, 丹皮) 3 qian, Auricularia Judae (Mu'er, 木耳) 3 qian, and Sinapis Alba Seed (Baijiezi, 白芥子) 2 qian. Decoct in water and take orally. One dose disperses the evil blood; a second dose is unnecessary. Then apply a plaster. The plaster formula is named Hu Xin Xian Dan (Heart-Protecting Immortal Plaster): Dahuang 1 liang, Myrrha (Moyao, 没药) 3 qian, Olibanum (Ruxiang, 乳香) 3 qian, White Beeswax (Baila, 白蜡) 1 liang, Pine Rosin (Songxiang, 松香) 5 qian, Drynariae Rhizoma (Gusuibu, 骨碎补) 5 qian, Dang Gui 1 liang, Notoginseng Radix et Rhizoma (Sanqi, 三七根) 3 qian, Testudinis Carapax et Plastrum (Baiguiban, 败龟板) 1 liang, and Moschus (Shexiang, 麝香) 5 fen. Grind each into fine powder. Take 1 liang of porcine subcutaneous fat (Zhubanyou, 猪板油). Melt the Baila and Songxiang with the pig fat in a copper pot, then mix uniformly with the herbal powders to form the plaster. Apply to the injured area, wrap with oil paper, and bind with cloth. Mild cases heal with one plaster; severe cases require only two. For injuries from heavy clamping sticks, approximately four plasters suffice to allow safe walking. These two formulas are extremely divine and miraculous: the internal formula disperses all evil blood, and the external formula promotes rapid regeneration of dead tissue. Used together, how could they harm human life?
