Team Tu Youyou solved this worldwide problem. This is inseparable from her own determination and perseverance, and of course, from the strength of her team.
After a series of setbacks, they saw hope in Ge Hong's elbow:
"Hold Artemisia annua, dye it with two liters of water, wring the juice, and take it all."
The 523 project team in Tu Youyou extracted three crystal components from Artemisia annua, and found an effective monomer for killing plasmodium: artemisinin II.
Making such a big breakthrough in such a short time is the strength of 523 cooperation. With questions, the experimental group continued to promote human experiments in Hainan. The antimalarial effect of artemisinin II is not obvious, and the side effects on the heart still exist. The project team began to doubt their research.
At this time, the advantages of "523 National Cooperation" appeared again.
During the period of 1973, researchers from Yunnan Institute of Medical Sciences were attracted by the absinthe that can be seen everywhere in Yunnan University, and wondered whether absinthe would also have antimalarial effects.
In April, Yunnan Medical Research Institute extracted Artemisia annua No.3 from Artemisia annua, and the effect was excellent in subsequent animal experiments.
Even the researchers are scared. Researchers have verified its medicinal properties many times and found that Artemisia annua No.3 is not only stable in drug resistance and has no side effects, but also qualified in animal and human experiments, with stable antimalarial effect and no side effects.
Tu Youyou won the Nobel Prize, which is a recognition of the scientific research achievements made by China researchers represented by her under the hard conditions of self-reliance, and is worthy of pride.
