Snapdragon
The Herbs

(Antirrhinum majus) Leaf: X

Folk Name: Calf’s Snout

Gender: Masculine

Planet: Mars

Element: Fire

Powers: Protection

Magical Uses: Any part of the snapdragon worn on your body prevents people from deceiving you. The seed worn around the neck ensures that you will never be bewitched.

If you are outside and feel evil nearby, step on a snapdragon or hold one of its flowers in your hand until the evil passes. Place a vase of fresh snapdragons on the altar while performing protective rituals.

If someone has sent negative energy to you (hexes, curses, etc.) place some snapdragons on the altar with a mirror behind them. This will send the curses back.
