Bezoar Stones (Burges Collection of Materia Medica, late 1700s)
Description
Bezoar stones were calculi from the intestines of various animals and were highly prized as poison antidotes, often being given as royal gifts in elaborate containers. These examples from porcupines are held in decorative cages on chains for suspending in liquid to create a kind of medicinal tea.
Fact
Bezoars feature in the Harry Potter novels as poison antidotes found in the stomachs of goats.
