Translation
Treats the amassed blood pattern with the pulse sunken, fine and faint, the skin cold and fullness below the navel, mania or agitation, the stool black and the urine passing freely; it is especially suited to the old, the young and the weak. Fresh rehmannia juice 1 seung <span class='sochu'>or 2 nyang of dried fresh rehmannia if there is none</span>; dried lacquer, stir-fried until the smoke is gone, half a nyang; fresh lotus root juice half a seung <span class='sochu'>or 1.5 seung of thistle juice if there is none</span>; fresh indigo leaf a handful <span class='sochu'>cut up; or half a seung of the dried powder if there is none</span>; tabanus twenty, stir-fried; leech ten, stir-fried; rhubarb 1 nyang, cut up; peach kernel, ground, half a nyang. Reduce together in 3 seung of water to 2 seung, let cool and divide into two doses; take the first and wait about half a day, and if the blood has not come down take again. This medicine is much lighter than the Resist Decoction and Pill; fearing that the Resist Pill would bring down blood without stopping, this decoction is used to govern instead. — Haejang 海藏 (Donguibogam · Hyeol)
