4. CAR T-cells, Ritual, Water, Crying

Joining Kiri this week are Dr Claire Roddie who retrains cells to fight cancer using revolutionary, game-changing CAR T-cell therapy, and comedian Fatiha El-Ghorri who finds spiritual healing in water. Dr Lindsey Fitzharris takes comfort in rituals both historical and present-day to help her remember her grandmother Dorothy Sissors, and Rev Benjamin Perry explains how crying can be the best medicine.

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 panellists 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.
