This week’s Claire Chats has been inspired by the recent video I did on Richard Hesketh and the Hesketh plot, in which I mentioned Ferdinando Stanley and his belief that he’d been poisoned, so he took bezoar stone and unicorn’s horn to try and counteract the poison. It made me want to dig a bit deeper into poisoning in the medieval and Tudor period, and find out what poisons were used to do away with people.
