The discovery of artemisinin has helped significantly reduce the mortality rates of malaria patients.

青蒿素的发现极大地降低了疟疾患者的死亡率。

Tu's research led to the manmade drug artemisinin, a drug now widely used to treat malaria.

屠呦呦的研究引发了人造药物青蒿素，这种药物现已广泛用于治疗疟疾。

Now, artemisinin can be toxic to human cells, too, for the same reason.

不过，青蒿素也会对人体细胞产生毒性，也是出于同样的原因。

And when artemisinin encounters hemozoin, the two compounds react to create unstable atoms known as free radicals.

当青蒿素遇到疟原虫色素时，这两种化合物会发生反应，产生被称为自由基的不稳定原子。

But luckily, artemisinin reacts more readily with hemozoin, than it does with the iron in our cells.

但幸运的是，青蒿素与疟原虫色素的反应比与我们细胞中的铁反应更容易。

As it turned out, the key to this life-saving cure was an active compound from the wormwood plant called artemisinin.

事实证明，这种救命疗法的关键是一种来自艾草植物的活性化合物，叫做青蒿素。

Tu Youyou is a Chinese scientist who managed to extract artemisinin from a Chinese herb.

屠呦呦是一位中国科学家， 他成功地从中草药中提取了青蒿素。

She was, of course, recognized for her discovery of artemisinin, the powerful medicine used to treat malaria.

当然，她因发现用于治疗疟疾的强效药物青蒿素而受到认可。

Plus, the chemistry of artemisinin is finicky, so only plant cells are really good at making it.

此外，青蒿素的化学成分非常复杂，因此只有植物细胞才能真正擅长制造它。

To be clear, these aren’t the first scientists to try and make artemisinin in different plants.

需要明确的是，这些并不是第一批尝试在不同植物中制造青蒿素的科学家。
