She devoted years to researching a cure for malaria, collecting over 2,000 herbal recipes and going through much trial and error. Thanks to her innovation, she succeeded in extracting qinghaosu from qinghao using cold water. Her discovery has saved millions of lives worldwide, making a huge contribution to medical science. Tu Youyou’s perseverance and dedication inspire countless people to pursue their dreams. 【参考范文（作业二）】 The Value of Traditional Chinese Medicine Traditional Chinese medicine (TCM) is a precious part of Chinese culture with great practical value, as proven by Tu Youyou’s story. Tu Youyou drew inspiration from ancient TCM books and succeeded in discovering qinghaosu, a treatment for malaria that has saved millions of lives. Her success shows that TCM contains profound wisdom and can provide solutions to global health problems. Besides, TCM focuses on holistic treatment and harmony between humans and nature, which complements modern medicine. Many TCM therapies, such as acupuncture and herbal remedies, have been widely recognized for their effectiveness. In my opinion, we should cherish and inherit TCM. By combining it with modern scientific methods, we can unlock more of its potential and let this ancient wisdom benefit more people around the world. 1 学科网（北京）股份有限公司 $
