To test the safety of artemisinin, Tu Youyou tried the drug himself. How did Tu Youyou change the world with a small grass?

Ms. Tu’s artemisinin is hailed as the greatest invention of the 20th century. Artemisinin against malaria has benefited all mankind.

Ms. Tu’s family conditions are not bad, and she has received a good education since she was a child. In the 19th century, the country was in turmoil, and few women could receive a good education. Ms. Tu studied in Hanxiang School in 1906. With a good learning environment and family influence, Ms. Tu has been exposed to various classical medical books such as "Shen Nong's Materia Medica" and "Treatise on Febrile and Miscellaneous Diseases" since she was a child. When she was 16 years old, she was forced to suspend her studies due to tuberculosis. After careful treatment, her health finally improved. After this disaster, her interest in medicine was further deepened. Later, Ms. Tu persisted in her dream and was admitted to the Department of Pharmacy, Peking University School of Medicine, majoring in pharmacognosy.

After Ms. Tu entered university, she studied even harder, and later entered the Institute of Traditional Chinese Medicine to work in the Institute of Traditional Chinese Medicine. This accumulated rich experience for her future scientific research on traditional Chinese medicine. In the 1960s, malaria appeared in many rural areas, and the mortality rate among children was extremely high. Many other developing countries have the same experience. So finding a new alternative to quinine could save thousands of lives. Our country has also set up a special research team. Among them, the discovery of artemisinin has rewritten the history of human health.

In the 1960s, my country's medical conditions were very primitive. So Ms. Tu led the working group to find methods from ancient Chinese books and documents. Finally I found the Artemisia annua recipe. But what kind of Artemisia annua, how to process it, and how to use it are not recorded. Later, Ms. Tu changed her method and used a low boiling point solvent. After many first failures, he finally succeeded. In order to better study artemisinin and enter clinical trials, I did not hesitate to try the medicine myself. With unremitting persistence and hard work, he finally achieved success. In 2015, Ms. Tu won the Nobel Prize in Physiology for this discovery. This artemisinin has benefited all mankind and brought good news to patients around the world.
