Chinese Nobel winner ‘not really surprised’
BEIJING—Tu Youyou, the first Chinese woman to win a Nobel prize for medicine, said Tuesday she was “not really surprised” to be recognized after a remarkable career that saw her team test a breakthrough malaria drug on themselves during the chaos of the Cultural Revolution.
“We carried out this research over a number of decades, so to win this award was not a surprise,” the 84-year-old told the Qianjiang Evening News from her home in Zhejiang.
Tu won half of the award for her work on artemisinin, an anti-malarial drug based on ancient Chinese herbal medicine, it was announced Monday.
Derived from a herb used to treat fevers some 1,700 years ago, the drug revolutionized cures for malaria and is credited with saving millions of lives.
“I was a little bit surprised, but not really,” she said of the moment she learned of the award as she watched television.
“It’s because (this prize) is not an honor just for me, but an honor for all Chinese scientists.”
In the late 1960s, Tu and a team investigated more than 2,000 Chinese herb preparations and at first identified 640 that had possible antimalarial activity—but with no significant results in experiments with mice except for one: Artemisia annua extract.
But when these promising results could not be replicated, the team were befuddled.
They turned to ancient Chinese literature for help, finding the answer in the writings of alchemist Ge Hong, who died in the year 343.
In “A Handbook of Prescriptions for Emergencies,” Ge described Artemisia’s properties for reducing the symptoms of malaria and gave this tip: “A handful of qinghao immersed with two liters of water, wring out the juice and drink it all.”
Centuries later, his words were a light-bulb moment.
“This sentence gave me the idea that the heating involved in the conventional extraction step we had used might have destroyed the active components,” Tu wrote in a 2011 article.
The researchers were working at the height of Mao Zedong’s chaotic 1966-1976 Cultural Revolution, which saw large numbers of people, including academics, persecuted.
