What's on A Medieval Summer Potions, Poisons and Poultices | Medieval Medicine Workshop Cow dung to soothe a tooth ache, arsenic to cure the plague, bloodletting to treat a nosebleed; many medieval treatments sound very strange to us today, if not downright dangerous! Come and find out more about the weird world of medieval medicine at our hands-on workshop. Learn about the important role monks played in looking after the sick, have a go at diagnosing your friends according to the Theory of Humours, and mix herbal remedies similar to those the monastic infirmarian would have prepared centuries ago. This workshop is best suited for ages 7 - 11. Ingredients used include English plantain leaf, greater plantain leaf, wild celery, lavender and shea butter. One ticket includes one child and their accompanying parent/carer. Children must be accompanied.
