三七(Panax notoginseng)含人参皂苷 Rg1/Rb1、三七皂苷 R1 及田七氨酸,兼具止血与化瘀的'双向'药理:生品富含田七氨酸缩短出血时间,同时总皂苷具抗血小板和扩张冠脉作用,对应'止血不留瘀'之传统论述。
Panax notoginseng contains ginsenosides Rg1/Rb1, notoginsenoside R1, and dencichine. It displays a dual hemostatic–antiplatelet pharmacology: raw powder rich in dencichine shortens bleeding time while total saponins are antiplatelet and coronary-vasodilatory, paralleling the classical claim of 'stopping bleeding without causing stasis'.
中国药典 2020 版收载三七,规定人参皂苷 Rb1、Rg1 及三七皂苷 R1 的总含量不低于 5.0%。
Chinese Pharmacopoeia 2020 specifies that Sanqi must contain no less than 5.0% total ginsenoside Rb1 + Rg1 + notoginsenoside R1.
Brinker 提示三七可增强抗血小板与抗凝药效应,与阿司匹林、华法林合用应监测出血风险。
Brinker notes that notoginseng may potentiate antiplatelet and anticoagulant drugs; bleeding risk should be monitored when combined with aspirin or warfarin.
Chen & Chen 综述田七氨酸促进血小板释放并缩短出血时间,而三七总皂苷抑制血小板聚集,从而实现双向调节。
Chen & Chen summarize that dencichine promotes platelet release and shortens bleeding time whereas total notoginseng saponins inhibit platelet aggregation, accounting for the bidirectional profile.

孕妇慎用。血虚无瘀者不宜。出血证属阴虚火旺者应配伍凉血药。不宜与抗凝血药(如华法林、阿司匹林)同用,有增加出血风险。
过量或长期服用可引起口干、烦躁、恶心、出血倾向增加。三七含人参皂苷,与抗凝药合用需谨慎。孕妇慎用,手术前一周宜停服。
《本草纲目》载:此药近时始出,南人军中用为金疮要药,云有奇功……凡杖扑伤损,瘀血淋漓者,随即嚼烂罨之即止;青肿者即消散。
