廣嗣要語

Guǎngsì Yàoyǔ 廣嗣要語

A mid-Míng treatise on fertility methodology by 俞橋 (Yú Qiáo, zì Sùhuízǐ 溯洄子), combining Daoist nèidān (inner-alchemy) doctrine with practical clinical-prescription material on producing descendants (guǎngsì). The text circulated independently in at least two earlier editions and is preserved as an appendix to KR3ed126 Jǐshì zhēnbǎo (Wáng Yǒng’s late-Míng compilation).
