双氢青蒿素（英语：Dihydroartemisinin是一种用来治疗疟疾的药物。双氢青蒿素是所有青蒿素类药物的活性代谢产物（包括青蒿素，青蒿琥酯，蒿甲醚等），并且其本身也是一种药物。双氢青蒿素是青蒿素的半合成衍生物，并且广泛作为其他青蒿素衍生物的中间体使用。

中国中医科学院1985年开始以还原青蒿素为基础，将其完善成双氢青蒿素，于1992年7月获得新药证书。双氢青蒿素抗疟疗效高于青蒿素10倍，可口服途径给药，而且复燃率明显降低。临床实验杀虫速度相当于静脉注射的青蒿琥酯，优于肌肉注射的蒿甲醚。

Dihydroartemisinin (also known as dihydroqinghaosu, artenimol or DHA) is a drug used to treat malaria. Dihydroartemisinin is the active metabolite of all artemisinin compounds (artemisinin, artesunate, artemether, etc.) and is also available as a drug in itself. It is a semi-synthetic derivative of artemisinin and is widely used as an intermediate in the preparation of other artemisinin-derived antimalarial drugs. It is sold commercially in combination with piperaquine and has been shown to be equivalent to artemether/lumefantrine.
