Tu Youyou
Chinese pharmacologist who discovered artemisinin-based antimalarials; awarded the 2015 Nobel Prize in Physiology or Medicine for her contribution to malaria treatment.
Overview
Tu Youyou (born 30 December 1930) is a Chinese pharmacologist and researcher best known for identifying artemisinin, the active compound that became the basis of modern antimalarial therapies. Her work built a bridge between traditional herbal knowledge and modern drug discovery and culminated in international recognition when she received the 2015 Nobel Prize in Physiology or Medicine.

Research and discovery
During the late 1960s and early 1970s Tu led a team investigating treatments for malaria as part of a national research effort. Drawing on traditional Chinese medical texts and systematic laboratory tests, she isolated a potent extract from the plant Artemisia annua (sweet wormwood). By modifying extraction techniques to preserve heat-sensitive components she obtained the compound artemisinin, which showed strong activity against the malaria parasite in laboratory and clinical studies. This approach combined empirical screening with insights from historical remedies.
Malaria, transmission and treatment
Malaria is an infectious disease caused by Plasmodium parasites and transmitted by female Anopheles mosquitoes. Severe malaria has been a major global health problem for centuries. Artemisinin and its derivatives became the backbone of artemisinin-based combination therapies (ACTs), now recommended worldwide for treating uncomplicated malaria. These therapies act quickly to reduce parasite levels and are widely credited with reducing malaria-related mortality where they are properly deployed. For background on the disease see malaria resources.
Impact, recognition and legacy
Tu's discovery transformed malaria treatment and led to widespread adoption of artemisinin-based drugs in public health programs. For this achievement she was jointly awarded the 2015 Nobel Prize, cited for her discoveries that led to a novel and effective medicine against malaria. Her career highlighted collaborative, multidisciplinary research and the potential value of traditional medicine as a source of therapeutic leads.
Notable facts
- Work combined laboratory pharmacology with historical herbal knowledge.
- Artemisinin derivatives include artesunate and artemether, used in combination therapies.
- Her research was part of a larger national effort to find antimalarial drugs.
- Recognition emphasized both scientific innovation and public-health impact.
Tu Youyou's contribution remains a prominent example of translating natural-product research into life-saving treatments. Her work continues to influence drug development and malaria control strategies worldwide.
