When I reviewed the book Defending Biodiversity: Environmental Science and Ethics, one of the reasons that was discussed as to why we should protect nature was the possibility of undiscovered pharmaceutical drugs. Seasoned ethnobotanist Robert A. Voeks shows that this so-called jungle medicine narrative has a long history. Though partially true, it equally contains parts myth, sentimentality, and nostalgia. However, if you are expecting a sceptical critique of superstitious indigenous practices – I was initially wondering whether the book would – no, this book delivers something far more interesting. Without belittling traditional knowledge, Voeks instead exposes the flaws in our interpretation and delivers a nuanced and fascinating ethnobotanical history lesson to boot.
