Nostradamus treated plague victims with pills he made from rose petals. He instructed patients to keep the pills under their tongues at all times and also claimed the rose remedy helped fight bad breath and tooth decay.
In addition to astrology and medicine, Nostradamus knew his way around a kitchen. In 1555, he published a book of recipes for cosmetics, perfumes and fruit preservatives.
Nostradamus predicted the world will end in 3797.
While living in Salon-de-Provence in the 1550s, Nostradamus invested heavily in an ambitious canal project designed by engineer Adam de Craponne to bring an irrigation system to the arid region. The canal was a success and still stands today.
