金代 · 张从正为代表 · 金元四大家之一
Jin dynasty · Represented by Zhang Congzheng · One of the Four Great Masters of Jin-Yuan
张从正（约1156–1228）主张「邪去则正安」，反对滥用温补。他擅长汗、吐、下三法攻逐病邪，认为许多疾病因邪气停留而起，祛邪即所以扶正。其学说与河间之寒凉、东垣之补土形成鲜明对照，体现了金元时期医学思想的多元争鸣。
Zhang Congzheng (c. 1156–1228) held that “when the pathogen is removed, the upright qi recovers,” and opposed indiscriminate warming and tonification. He specialised in the three methods of sweating, emesis and purgation to expel pathogens, arguing that many diseases arise from lingering evil qi. His approach stood in clear contrast to Hejian’s cooling and Dongyuan’s spleen-supplementation, illustrating the pluralistic debates of the Jin-Yuan period.
