7. Lethal Lipstick for Queen Elizabeth I
Whether the church approved of it or not, Queen Elizabeth I loved her red lipstick. She would put it on liberally every day, and she even thought it had healing and protective powers. There was just one problem, though: It was made with lead, and it was slowly poisoning her. 

Her favorite paint eventually ended up killing her, and when they found her dead in her chamber it was said that she had a whopping half an inch of lipstick caked on.
