Yè Dàlián 葉大廉 (fl. mid-to-late 12th c., Southern Sòng), native of Yánpíng 延平 (Nánjiànzhōu 南劍州, modern Nánpíng 南平, Fújiàn). Member of an established Yánpíng medical family, Yè held official rank — described in the 1204 second postface as Tàishè 太社 (an officer in the imperial ritual administration) — and travelled in the four directions of the Southern-Sòng empire in office, accumulating clinical recipes throughout his career. He served administratively in Lóngshū 龍舒 (Shūzhōu, Ānhuī) at the time of his first printing.
His principal extant work is the Yèshì lùyàn fāng 葉氏錄驗方 (KR3ed130) in 3 juǎn, printed in 1186 (Chúnxī bǐngwǔ) at the Lóngshū prefectural office, with collation by Liú Liángshū of Shòuchūn and Xǔ Yáochén of Sānshān. The work was reprinted in 1204 (Jiātài jiǎzǐ) at the Dōngyáng prefectural office with a second postface by a colleague-administrator who had personally tested Yè’s formulas in the prefectural jails and among the populace of Zházhōu and Wùzhōu. The work is one of the principal Southern-Sòng formularies preserved in the Sìkù quánshū.
Yè’s editorial stance — to publish family-secret formulas rather than to keep them within the clinic-practice — is notable for the period and anticipates the broader YuánMíngQīng charity-publishing tradition.
