In this episode we explore the history of the bladder. It’s a urine-heavy episode as we take a deep dive into diuresis – including locally sourced diuretics commonly used in Scotland such as leeks, watercress and barley water. We also take a look at the taste-tastic practice of uroscopy, the communal history of chamberpots and the all important question – if both doctors and quacks are tasting urine, how do you decide who to trust with your health?
