In this video, we look at sources of medicines. First we look at antibiotics, including penicillin. Next we look at how medicines can be sourced from living organisms, including willow and foxgloves and why this means that it’s important to preserve biodiversity. Finally we explore what is meant by pharmacogenomics and synthetic biology and why these will be important in the future.
