Besides wearing the corno, an old wive's tale says that to diagnose someone with the evil eye, have them drop three drops of olive oil in a bowl filled with water. If the oil forms the shape of an eye, the victim has indeed received the malocchio.

How do I know if I have malocchio?

You can tell if someone has been cursed with the “evil eye” by dropping 3 drops of olive oil in a bowl of water. It the oil moves into the shape of an eye then they have been cursed.

When can you learn malocchio?

According to community lore, malocchio healers can only learn the prayer and accompanying oil-in-water tradition at midnight on Christmas Eve, a supposedly sacred passing-on from one moment in time to the next.
