madstone. Any hard substance extracted from the digestive system of an animal (such as a hair ball in a deer’s stomach) and used to treat the bites of mad dogs was called a madstone by Americans in the 19th century. Thousands of people be- lieved that they were cured of snakebites, bee stings, spider stings, and other bites by madstones. Abraham Lincoln, in fact, had his son treated for dog bite with a madstone applied to his wound. |
