Exchange the Bones Elixir

Hwangol-dan

한글 환골단  ·  Pinyin Huan Gu Dan

換骨丹

麻黃煎膏 — the ephedra paste used as the binding agent — is cross-referenced to the Miscellaneous Prescriptions chapter, which is not yet transcribed on this site, so the name is left unlinked. 勿令陰人見 — let no yin person see — means that women were to be kept from the compounding room, a taboo common in the elixir literature. The cinnabar coating has no weight given.

Translation

Treats wind stroke with deviation of the mouth and eye and paralysis, and also hidden wind and wind epilepsy. Atractylodes lancea, sophora fruit, mulberry root bark, chuanxiong, angelica dahurica, clematis, ginseng, saposhnikovia, polygonum multiflorum and vitex fruit, 1 nyang each; sophora flavescens, schisandra and costus, 5 don each; borneol and musk, 5 fun each. Powder and mix with ephedra paste, pound ten thousand strokes, make ten pills to the nyang and coat with cinnabar. Take one pill ground into half a cup of warm wine, covered with something so that no air escapes; after food and at bedtime swallow it in one draught, cover with bedclothes to bring out the sweat, and recovery follows. The verse: I have the Exchange the Bones Elixir, handed down in the deepest secrecy. It opens out the sick man's heart and lifts up the failing old man's arm. The qi made strong, the years are lengthened; the spirit clear, the eyes need no sleep. The immortal Elder Zhang of the Southern Mountain was three hundred and eighty years old. Sophora bark, chuanxiong, atractylodes, angelica dahurica, clematis, saposhnikovia, polygonum and vitex — ten items in equal measure; the bitter, the sour and the fragrant at half; of borneol and musk only a little; cinnabar wrapped on as a coat. Pilled with ephedra paste, the size of a finger-flicked ball. Compound it in a deep room and let no yin person see. Lying down at night take one pellet, and the whole body fills with sweat. The ten thousand diseases vanish of themselves, and the immortals become your companions. Ephedra paste treats sudden wind stroke with loss of consciousness; this paste is added into decoctions and taken, or used to pill medicines. — Uihak Immun 入門 · Danggye Simbeop 丹心 (Donguibogam · Pung)

Clinical commentary 臨床

**This must not be prepared.** Musk is from a CITES-listed species, and cinnabar is mercuric sulphide. What makes the entry remarkable is the mnemonic verse, which the Bogam quotes in full from the Danggye Simbeop: it names every drug in order, gives the three weight tiers, specifies the binder, sets the dose and even the taboo about who may watch the compounding. That is a complete formula encoded for memorization, and it is the clearest surviving example in the book of how prescriptions travelled among practitioners who could not carry a text. The claim about Elder Zhang's three hundred and eighty years places it in the immortality literature rather than the clinical, and the 風非大汗則不除 heading it sits under — wind is not removed without a great sweat — is the doctrine it serves. — Eui Young (Justin) Chung, L.Ac., Dipl. O.M.
