Using a lower temperature to draw out the extract, she found a substance that
worked. After failing more than 190 times, the team finally succeeded in 1971.
Tu Youyou and her team members even insisted on testing the medicine on
themselves to make sure that it was safe. Later, the medicine was tested on
malaria patients, most of whom recovered. This medicine, which was called
artemisinin, soon became a standard treatment for malaria.

According to Tu Youyou, the discovery of artemisinin was a team effort. Upon
hearing that she had been awarded the Nobel Prize, she said, “The honour is
not just mine. There is a team behind me, and all the people of my country.
This success proves the great value of traditional Chinese medicine. It is indeed
an honour for China’s scientific research and Chinese medicine to be spread
around the world.”
