Fatal Alchemy
From Nick CurreyAbout the film:
Miracle beauty products may be a staple today, but they're not a recent invention. Diane de Poitiers, a French noble woman and mistress of Henry II of France, tried to use gold to preserve her looks - in alchemical law, gold was immutable, and alchemists and apothecaries created various potions to pass this gift onto their customers.This is a film for the BMJ about a French research team's investigations of Diane's remains, and its discovery that the gold she used to preserve her youth was actually slowly poisoning her.
