In those forests of China we have surviving species like gingko, the maidenhair tree which has been in cultivation in Europe and North America since the17th century. 在中国的森林里我们可以找到银杏和孔雀草,它们从17世纪开始就在欧洲和北美被种植。
For centuries, traditional Chinese physicians have used extracts from leaves of the maidenhair tree, Ginkgo biloba, to treat asthma, bronchitis, and brain disorders. 几个世纪以来,传统的中医师一直将铁线蕨和银杏叶等植物的提取物应用于治疗哮喘、支气管炎和大脑功能障碍等疾病。
