Mimosa
The Herbs
(Acacia dealbata) P
Folk Names: Mimosa Pudica, Albizzialebbeck
Gender: Feminine
Planet: Saturn
Element: Water
Powers: Protection, Love, Prophetic Dreams, Purification
Magical Uses: Mimosa is used in spells involving purification (scatter around the area), love, healing, and prophetic dreaming. The latter use, of course, entailing its placement beneath the pillow and subsequently sleeping on it.
A bath of mimosa (or an infusion of the plant sponged onto the body) destroys hexes and curses, and guards against future problems.
