Donguibogam 東醫寶鑑

此藥久服則身輕, 隨風而去, 如列子之乘虛. 若髮白者, 從根而黑, 如未白者, 永不白. 有不信者, 將藥拌飯與白猫吃, 一月卽黑. 地骨皮ㆍ生地黃ㆍ石菖蒲ㆍ牛膝ㆍ遠志ㆍ兎絲子(酒煮). 右等分, 爲細末, 蜜丸梧子大, 每三五十丸, 空心, 溫酒, 或鹽湯送下. 修製忌鐵器, 及婦人雞犬見. 《海藏》

Translation

Taken long, this medicine lightens the body so that one goes off with the wind, as Liezi rode the void. If the hair is white it blackens from the root; if not yet white, it will never whiten. For anyone who doubts it — mix the medicine into rice and feed it to a white cat, and in a month the cat turns black. Lycium root bark, raw rehmannia, acorus, achyranthes, polygala, and cuscuta (boiled in wine), in equal parts. Powder finely, form into honey pills the size of firmiana seeds, and take 30 to 50 on an empty stomach, sent down with warm wine or salt decoction. In preparing it avoid iron vessels, and do not let women, chickens, or dogs see it. — Haejang 海藏 (Donguibogam · Mobal)

Clinical commentary 臨床

The white-cat demonstration is the earliest animal trial in this chapter and its logic is sound even if its premise is not: the compiler is proposing a visible test for a claim that would otherwise take years to check on a person. The composition is more restrained than the promises around it — six herbs, equal parts, supplementing Kidney and Liver with acorus and polygala to carry the action upward to the head. Note the two preparation taboos: iron vessels, which would react with the tannins and darken the medicine wrongly, and the prohibition on being observed, which belongs to the alchemical rather than the medical layer of the text. — Eui Young (Justin) Chung, L.Ac., Dipl. O.M.
