Youyou (呦呦) is from the *Book of Songs* (*Shijing*) — the cry of the deer eating wild herbs in the field. **Tu Youyou (born 1930)** is the **Chinese pharmacologist who won the 2015 Nobel Prize in Physiology or Medicine** for discovering **artemisinin** — the antimalarial drug derived from sweet wormwood (Artemisia annua) that has saved millions of lives. **The first Chinese mainland scientist to win a Nobel Prize in a science category, and the first female Chinese Nobel laureate.**
Her parents chose her name from the deer's cry in the ancient hymn.
Youyou reduces to five — the number of Nobel laureate.
