Right, roll up your sleeve, it’s time for an extra dose of Best Medicine!

This is a special episode of unheard bits that couldn’t be squeezed into Series 2, featuring more fascinating medical insights, extended bits and a whole Petri dish of jokes – some more cultured than others.

Laura Smyth shares more on sleep, Zoe Lyons delves into transplants and Dr Lindsey Fitzharris takes Kiri through more weird ritualistic historical medical practices. Dr Matt Morgan talks about the time he stripped naked and covered himself in honey in the name of science, Daliso Chaponda is still in denial about denial, Dr Mark Williams blows Kiri's mind with his unexpected swimming career, and Reverend Benjamin Perry opens up again about the benefits of crying.

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 her panel 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 every-day treatment, an uplifting worldview, an unsung hero or a futuristic cure.

Whether it’s futuristic 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.
