Translation

A secret transmission for hastening birth. Cicada slough 1 nyang, and one large snake slough — both burnt with their nature retained; talcum and lightly dry-fried mallow seed, 1 nyang each. Powder the above; take 1 don each time stirred into slightly warmed downstream-flowing water. It must not be given in hot water. — Deukhyo 得效 (Donguibogam · Buin)

Clinical commentary 臨床

The two chief ingredients are both things that were shed and left behind — a cicada's shell and a snake's skin — and the reasoning is sympathetic: what slipped out of its own casing can help another do the same. Beneath that sits perfectly ordinary pharmacy, talcum and mallow seed for slipperiness and downward passage. The instruction about the water is the interesting detail: downstream-flowing water, barely warmed, and never hot — the vehicle chosen for its direction of travel. — Eui Young (Justin) Chung, L.Ac., Dipl. O.M.
