Joining Kiri this week at the Hay Festival is comedian Zoe Lyons who tells Kiri how running helps with the stress associated with her alopecia - and how she survived getting rammed by a badger. Dr Matt Morgan explains how kangaroo vaginas held the key to developing IVF and whales’ hearts inspired new heart treatments for humans, Dr Fotios Sampaziotis unveils innovative new treatments that could repair livers before a transplant is needed, and ethnobotanist James Wong unearths the benefits of horticulture and how it can benefit health and bring hope.

Best Medicine is your weekly dose of laughter, hope and incredible medicine. Award-winning comedian Kiri Pritchard-McLean is joined by a funny and fascinating panel of comedians, doctors, scientists, and historians to celebrate medicine’s inspiring past, present and future.

Each week, Kiri challenges a panel of medical experts and a comedian to make a case for what they think is 'the best medicine', and each guest champions anything from world-changing science or an obscure invention, to an everyday treatment, an uplifting worldview, an unsung hero or a futuristic cure.

Whether it’s origami surgical robots, life-changing pineapple UTI vaccines, Victorian scandal mags, denial, sleep, tiny beating organoid hearts, lifesaving stem cell transplants, gold poo donors or even crying - it’s always something worth celebrating.
