Wáng Mènglán 王夢蘭 (fl. mid-Qing, 18th c.?) is the otherwise undocumented compiler of the Mìfāng jíyàn 秘方集驗 KR3ed072, a formulary collection of “secret recipes” tested in practice. The work covers internal medicine, gynaecology, external medicine and emergency care, with strong attention to bites (mad dog, venomous insect, snake) and to poisons. No CBDB entry; no firm dating beyond the broad Qīng dynasty placement of the catalog meta. The work was repeatedly reprinted in late-Qing and Republican popular formulary anthologies.
