I. Lead in
Malaria is a serious disease. You get it after an infected mosquito bites you. Malaria is a major cause of death worldwide, being mostly a problem in developing countries with warm climates. It can be life-threatening.
Chinese scientist Tu Youyou found an effective drug called qinghaosu.

READ AND ANSWER
1. When and how did Tu create the treatment?
In 1969, Tu became the director of a national project to develop a drug against malaria. Her team took a unique approach. They studied books about classical Chinese medicine. After reading more than 2,000 old remedies, Tu and her team collected over 600 plants and listed almost 380 possible remedies for malaria. One remedy, which is 1,600 years old, uses sweet wormwood as a treatment. Tu found it effective.
2. What problem did Tu encounter? What was the solution?
Tu found sweet wormwood effective and tried to extract the qinghaosu from it in order to make a drug. The extraction failed at first.
She used a low-temperature method to extract the qinghaosu and finally succeeded in 1972.
3. How did Tu prove the effectiveness of the treatment?
After her team showed that qinghaosu could treat malaria in mice and monkeys, Tu and two of her colleagues volunteered to test the drug on themselves before testing on human patients. It turned out that qinghaosu was safe and all patients in the test recovered.
