Martha Kearney meets Jane Anderson, one of the UK's leading physicians in HIV medicine, to learn about the living library of plants at Chelsea Physic Garden. Since childhood, Jane has always been a huge lover of plants and their many remarkable uses - for food, for medicine, for health and wellbeing. As they walk around the medicinal plant beds, she speaks about human health and planetary health, and how they are both completely interconnected.
