论治疥 论止手汗 论治癞头
天师曰∶浴治者，以水煮滚浴之也。如人生疮、生疥者是。不可在浴堂内去浴，必须在自家屋内。
用苦参四两，生甘草一两，金银花一两，苍耳草半斤，荆芥一两，防风一两，生黄 三两，水煮汤一大
锅，乘热熏之，外用席二条，裹住身上，用衣盖之，使气不散，俟稍凉浴之，必至汤寒而后已。一日再
浴，将渣再煎，如前浴之，三日疮疥必全愈也。
熏不可为训，恐引毒入脏腑也。熏者，乃用药裹在纸内，或在火炉，同人熏于被内者是，切不可
用之，不若洗浴之为妙。
张公曰∶妙。人有手汗出者，以黄 一两，葛根一两，荆芥三钱，防风三钱，水煎汤一盆，热熏而温
洗，三次即无汗，神方也。即是此汤亦可，然不若每日一换药之为妙也。
更有癞头洗方∶用蜗牛数十条，以癞头洗之，二次必全愈，亦神方也。水三碗，煎蜗牛三十条足矣。
华君曰∶无。
论火丹砂疹
天师曰∶达治者，乃火郁于胸中而不得散，因而达之外
也。火气热甚，蕴蓄日久，则热势益盛，往往变为火丹之症，或发砂疹是也。若不急为达之，则火势燎
原，立刻灰烬。方用升麻三钱，元参八两，干葛三两，青蒿三两，黄 三两，水煎服。（〔批〕达郁
汤。）此方之奇，奇在青蒿与元参同用。盖火丹砂疹之病，乃胃火与肝结之火，共腾而外越，治肝则胃不
得舒，治胃则肝不得泄。今妙在用青蒿，青蒿平胃火，兼能平肝火，然未免性平而味不甚峻，又佐之元
参之重剂，则火势散漫，无不扑灭矣。然而青蒿虽平胃肝之火，而胃肝二火相形，毕竟胃火胜于肝火，又
佐以干葛之平胃，此方之斟酌咸善，而人不可测度者也。达治之法也。
张公曰∶达治法，古今绝妙异方，目中不曾多见，此方实奇而当。予更增一方，亦可少佐高深。白
芍三钱，柴胡二钱，丹皮二钱，元参三钱，麦冬三钱，荆芥三钱，生地三钱，炒栀子三钱，防风一钱，天
花粉二钱，水煎服。（〔批〕固本散）。此方专散肝木中之火，达其肝木之火，而诸经之火尽散矣。
华君曰∶无。
孙真人传治火丹神效。丝瓜子一两，柴胡一钱，元参一两，升麻一钱，当归五钱，水煎服。一剂即

On the Treatment of Scabies, Stopping Hand Sweating, and Treating Tinea Capitis (Lai Tou)
The Heavenly Master stated: "Bath therapy" refers to bathing with water that has been boiled. This applies to conditions such as sores and scabies. One must not bathe in public bathhouses but must do so within one's own home.
Use 4 liang of Sophora flavescens root (Kushen), 1 liang of raw Licorice root (Sheng Gancao), 1 liang of Honeysuckle flower (Jinyinhua), 0.5 jin of Xanthium herb (Cangercao), 1 liang of Schizonepeta spike (Jingjie), 1 liang of Saposhnikovia root (Fangfeng), and 3 liang of Astragalus root (Sheng Huangqi). Add water and boil to make a large pot of decoction. While hot, fumigate the body. Wrap the body tightly with two bamboo mats and cover with clothing to prevent the medicinal vapor from dissipating. Once the temperature cools slightly, proceed to bathe. Continue until the decoction becomes completely cold. Bathe twice a day. Re-boil the dregs and bathe as before. After three days, the sores and scabies will be completely healed.
Fumigation should not be used as a standard practice, as it may draw toxic pathogens into the zang-fu organs. "Fumigation" here refers to wrapping herbs in paper or placing them near a stove, allowing the patient to receive the herbal vapor inside a quilt. This method must strictly be avoided; bathing is far superior.
Master Zhang said: Excellent. For individuals suffering from hyperhidrosis of the hands, use 1 liang of Astragalus root (Huangqi), 1 liang of Kudzu root (Gegen), 3 qian of Schizonepeta spike (Jingjie), and 3 qian of Saposhnikovia root (Fangfeng). Decoct in water to make a basin of liquid. Fumigate with heat first, then wash with warmth. After three applications, sweating will cease. This is a miraculous formula. The aforementioned bath formula can also be used, though changing the herbs daily is preferable.
Another prescription for washing tinea capitis (Lai Tou): Use dozens of snails to wash the affected area. Complete healing occurs after two washes; this is also a miraculous formula. Three bowls of water are sufficient to decoct thirty snails.
Master Hua said: No additions.
On Erysipelas (Huodan) and Sand Rash (Shazhen)
The Heavenly Master stated: "Da therapy" (Reaching/Dispersing therapy) is indicated when fire pathogenic factors are constrained in the chest and cannot disperse, thus requiring a method to vent them outward. When fire heat is severe and accumulates over a long period, the heat intensity increases, often transforming into erysipelas or manifesting as sand rash. If not urgently dispersed, the fire will spread like a prairie fire, reducing everything to ashes instantly. The prescription uses 3 qian of Cimicifuga rhizome (Shengma), 8 liang of Scrophularia root (Yuanshen), 3 liang of Kudzu root (Gange), 3 liang of Artemisia annua (Qinghao), and 3 liang of Scutellaria root (Huangqin). Decoct in water and take orally. (Commentary: Da Yu Tang / Depressing Fire Decoction.) The uniqueness of this formula lies in the combined use of Qinghao and Yuanshen. The pathology of erysipelas and sand rash involves stomach fire and liver-constrained fire rising together and venting outward. Treating only the liver prevents the stomach fire from relaxing; treating only the stomach prevents the liver fire from draining. The brilliance here is the use of Qinghao, which pacifies stomach fire and simultaneously pacifies liver fire. However, its nature is mild and its flavor not sufficiently pungent/drastic. By assisting it with a heavy dose of Yuanshen, the scattered fire is extinguished. Although Qinghao pacifies stomach and liver fire, given that stomach fire typically outweighs liver fire in this context, the addition of Gange to pacify the stomach makes the formulation perfectly balanced, a subtlety beyond ordinary comprehension. This constitutes the method of Da therapy.
Master Zhang said: The Da therapy method represents an extraordinary ancient and modern prescription, rarely seen by my eyes. This formula is indeed unique and appropriate. I add another formula to supplement this profound approach: 3 qian of White Peony root (Baishao), 2 qian of Bupleurum root (Chaihu), 2 qian of Moutan bark (Danpi), 3 qian of Scrophularia root (Yuanshen), 3 qian of Ophiopogon tuber (Maidong), 3 qian of Schizonepeta spike (Jingjie), 3 qian of Rehmannia root (Shengdi), 3 qian of Stir-fried Gardenia fruit (Chao Zhizi), 1 qian of Saposhnikovia root (Fangfeng), and 2 qian of Nardostachys root (Tianhuafen). Decoct in water and take orally. (Commentary: Gu Ben San / Root-Firming Powder.) This formula specifically disperses fire within the Liver Wood system, venting liver fire so that fire in all meridians dissipates.
Master Hua said: No additions.
Sun Simiao transmitted a miraculous effective prescription for erysipelas. 1 liang of Luffa fruit (Sigua Zi), 1 qian of Bupleurum root (Chaihu), 1 liang of Scrophularia root (Yuanshen), 1 qian of Cimicifuga rhizome (Shengma), and 5 qian of Angelica sinensis root (Danggui). Decoct in water and take orally. One dose results in resolution. (Commentary: The Heavenly Master states: An extremely unique and wonderful formula.)
