“Immense quantities of arsenic are consumed by the peasants of Styria and the Tyrol,” The Daily Republican declared in 1901. “According to a Dr. Lorenzo, in that district the arsenic is taken fasting, usually in a cup of coffee, the first dose being minute, but increased day by day, until it sometimes amounts to the enormous dose of 12 or 15 grains. He found that the arsenic eaters were usually long-lived, though liable to sudden death. They have a very fresh, youthful appearance and are seldom attacked by infectious diseases.” The frequency with which people used arsenic varied between every two weeks to incorporating it into their daily diets.
