Li stresses that most of today's drugs are extracted from plants, and many sufferers of emerging diseases are awaiting new drug treatments. Hope lies in the rainforests, home of many plants we know nothing about. But of the 300,000 or so species of plants, no more than 5,000 have been researched for pharmaceutical purposes.
李家維強調，今天的醫藥大多仰賴從植物體中萃取，未來還有許多新興疾病等待克服，很多新藥等待開發，希望就寄託在雨林裡、那些我們幾乎對它毫無所知的植物上，然而地球上 30 萬種植物中，曾經被分析藥效的，不超過 5,000 種。
