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
消。（〔批〕天师云∶绝奇绝妙之方。）
天师说：所谓“浴治”，就是用煮沸的水进行洗浴。比如人生疮、生疥的情况就是如此。不可以去公共浴堂洗澡，必须在自家屋内进行。
使用苦参四两，生甘草一两，金银花一两，苍耳草半斤，荆芥一两，防风一两，生黄芪三两，加水煮成一大锅汤药。趁热气熏蒸身体，外用两条席子裹住全身，再用衣服覆盖，使药气不致散失，等到水温稍凉时再洗浴，必须直到药汤完全变冷才停止。一天洗浴两次，将药渣再次煎煮，像之前那样洗浴，三天后疮疥必定全部痊愈。
熏蒸法不可作为准则，恐怕会将毒邪引入脏腑。所谓的“熏”，是指将药物包裹在纸内，或者放在火炉旁，让人在被窝内接受药气熏蒸的方法，这种方法切不可使用，不如洗浴的方法精妙。
张公说：妙啊。有人手掌出汗的，用黄芪一两，葛根一两，荆芥三钱，防风三钱，加水煎成一盆汤药，先热熏后温洗，三次之后就不再出汗，这是神效之方。也可以用这个汤药，然而不如每天更换药材来得精妙。
还有治疗癞头（头部脓疱疮或严重头癣）的清洗方：用数十条蜗牛，用来清洗患部，两次即可全部痊愈，也是神效之方。只需三碗水，煎煮三十条蜗牛即可。
华君说：没有补充。
天师说：“达治”，是因为火邪郁结在胸中无法散发，因此采用“达”法将其向外透达。火气热势很盛，蕴积日久，则热势更加旺盛，往往转变为火丹症，或者发出砂疹。如果不紧急地予以透达，火势就会燎原，瞬间化为灰烬。方剂使用升麻三钱，玄参八两，干葛三两，青蒿三两，黄芩三两，加水煎服。（批注：达郁汤。）此方的奇妙之处，在于青蒿与玄参同用。因为火丹砂疹的病机，是胃火与肝经郁结之火共同腾越而外发，如果只治肝，则胃火不得舒展；如果只治胃，则肝火不得宣泄。如今妙在用青蒿，青蒿能平抑胃火，兼能平抑肝火，但未免药性平和而味道不够峻烈，又辅以重剂的玄参，那么散漫的火势就能被扑灭。然而青蒿虽然能平抑胃肝之火，但在胃肝二火相争的情况下，终究是胃火胜于肝火，又辅以干葛来平抑胃火，此方斟酌得当，精妙之处常人难以测度。这就是达治的方法。
张公说：达治法，是古今绝妙的异方，我眼中未曾多见，此方确实奇特且恰当。我再增加一方，也可稍助高深之意。白芍三钱，柴胡二钱，丹皮二钱，玄参三钱，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，加水煎服。（批注：固本散）。此方专门疏散肝木中的火邪，透达肝木之火，则各经之火尽皆消散。
华君说：没有补充。
孙真人传授治疗火丹的神效方。丝瓜络一两，柴胡一钱，玄参一两，升麻一钱，当归五钱，加水煎服。服用一剂即消退。（批注：天师说：这是极其奇特精妙的方子。）
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.)
