She discovered artemisinin(青蒿素). Tu conducted research in the 1970s that led to the discovery of artemisinin, a drug that has considerably cut the number of malaria(疟疾) deaths and saved millions of lives. The treatment is based on an herb(药草) used in Chinese traditional medicine, called sweet wormwood.Artemisinin-based drugs are now the standard treatment for malaria. The committee(委员会)said the discoveries have given the world powerful new ways to fight two pow-erful diseases. It said those diseases affect hundreds of millions of people every year. Despite rapid progress in controlling malaria in the past decade, the mosquito-borne disease still kills more than half a million people a year in the poorest parts of Africa. The committee added that，“The results in terms of improved human health and reduced suffering are immeasurable.” Ms. Tu is the chief professor at the China Academy of Traditional Medicine. A member of the Nobel committee said that the award for Tu Youyou is the result of a great change in the way China performs scientific research. He says China has invested(投资) a lot of money in such research.This member adds that the work of the three scientists could help end the health risk of diseases affecting 3.4 billion people.
