Aqua Tofana was a type of poison that was used a long time ago. It was made by a woman named Giulia Tofana in Italy during the 17th century. The poison was very dangerous and it could kill many people.
The poison was made of some really bad ingredients. There was arsenic, which is a poison that can make people really sick or even kill them; lead, which is a metal that can also poison people; and belladonna, which is a plant that can make people feel like they're dreaming and can also be very dangerous.
Giulia Tofana created the poison because she wanted to help women who were trapped in bad marriages. These women couldn't leave their husbands, but they wanted to get rid of them. So Giulia marketed her poison to them as a way to get out of their bad marriages.
She sold the poison to women in small glass bottles that looked like perfumes. Women would put a drop of the poison in their husband's food or drink, and it would kill him slowly over the course of a few days or weeks.
Many women used Aqua Tofana to get rid of their husbands, and it became very popular. But eventually, the authorities found out what was going on and Giulia Tofana was arrested and put to death for her crimes. The use of Aqua Tofana became illegal, and it is no longer used today because it's very dangerous and can cause a lot of harm to people.
