以同治同

以同治同是顺势疗法中一个重要原则，拉丁文similia similibus curantur可翻译成“以同类来治疗同类”，指的是如某物质能使健康的人患病，那么将此物质稀释震荡处理后就能治疗该病。^[1]例如于顺势疗法中，咖啡就被用以医治心悸、失眠。因为咖啡能导致“心悸、失眠”，所以经稀释震荡处理后的咖啡就能治疗类似咖啡引起的症状（心悸、失眠）。

德国医师萨穆埃尔·哈内曼，于翻释苏格兰医师及化学家威廉·库伦（英语：William Cullen）的医学著作时，构思出顺势疗法的概念。哈内曼对库伦以金鸡纳治疟疾的理论有所质疑，就服用了一些金鸡钠树皮以观察其作用。随之而来的是发烧，打冷战和关节毒，这些都是类似于疟疾的症状。就此哈内曼推断，凡有用之药，必使健康之人得症，其症类同于欲治之病，亦即古医术中"以同治同"之说法。^[2]但同样是服用金鸡纳树皮，老奥利弗·温德尔·霍姆斯于1861年的实验却未能得出相同的结果。^[3]哈内曼的以同治同法则不过是个假设，而不是科学的定律。^[4]

相关科学研究显示金鸡纳能治疗疟疾，是因内含奎宁，能杀死致病的疟原虫。亦即是说引起症状的机制并非金鸡纳有疗效的原因。^[5]
