Send us Fan Mail Taking a break for an episode to talk poisons! Specifically the famous Aqua Tofana poison that was circulated and sold in 17th century Italy. I found so many incorrect sources on this so below are the ones that could be verified: wikipedia: Aqua Tofana, Guilia Tofana, Spana Prosecution, Thofania d'Adamo, Anna Maria Conti, Tor di Nonna https://www.ucl.ac.uk/~ucgajpd/medicina%20antiqua/sa_poisons.html
