Yú Qiáo 俞橋 (zì Zǐmù 子木, hào Sùhuízǐ 溯洄子, “The One who Traces-back-against-the-current”, fl. mid-Míng, mid-16th century), Daoist-affiliated physician and inner-alchemy adept. Native of Hǎiníng 海寧 (Zhèjiāng). Author of:
- Guǎngsì yàoyǔ 廣嗣要語 — a treatise on fertility methodology combining inner-alchemy doctrine with practical clinical-prescription material. Preserved as the appendix to KR3ed126 Jǐshì zhēnbǎo (Wáng Yǒng’s compilation) and also in independent printings (the Wàn Lùyuán edition of the Brocade-Robed-Guard officer Wànjūn, and the Liú Zhònghéng edition of a District Magistrate). The preface describes Yú as having received great-Dào transmission from an extraordinary man in his early years; in late life he applied the forward-cultivation (shùnxiū) method and produced three sons, the experiential anchor for his treatise. The work is one of the most-cited mid-Míng works on the heir-producing topic.
- Yīxué cǎnjiǎn yào 醫學參簡要 — a clinical manual.
Yú’s theoretical apparatus — xiāntiān / hòutiān, shùnxiū / nìxiū, tàijí qì / tàishǐ qì — is consistent with the Quánzhēn inner-alchemy lineage. His combination of Daoist metaphysics with practical clinical prescribing on fertility constitutes one of the most-distinctive Míng-period fusions of theoretical and pharmacological knowledge.
