Zhāng Lǔfēng 張魯峰 (hào Àitáng 馤塘), Qīng physician active in the Jiāqìng — Dàoguāng era (early-to-mid nineteenth century) of the Lower Yangtze. Author of KR3eq004 Àitáng yīhuà 馤塘醫話 (1 juǎn) and of a lost Gānqì lùn 肝氣論 compendium of which the yīhuà is the published condensation. Distinctive for the doctrinal thesis — argued with extensive reference to Wèi Zhīxiù’s 魏之琇 Xù lèiàn and Wú Tāng’s 吳瑭 Wēnbìng tiáobiàn — that most male and female complaints of the post-Qián-Jiā transition era are mediated by Liver-qì derangement (gānqì bìng 肝氣病) rather than by Spleen-Stomach failure on the 李杲 Lǐ Dōngyuán model; his recipe-list is therefore dominated by xiāoyáo sǎn 逍遙散-type Liver-soothing preparations.
