Dittany of Crete
The Herbs
(Dictamus origanoides, D. albus) G
Gender: Feminine
Planet: Venus
Element: Water
Powers: Manifestations, Astral Projection
Magical Uses: Dittany, when burned, is an excellent base for manifestations of spirits; the wraiths appear in the smoke rising from the censer.
Dittany is also mixed with equal parts of vanilla, benzoin and sandalwood to make an astral projection incense. Burn a small amount prior to making the attempt.
The juice of the dittany drives away venomous beasts, so smear some onto your body before venturing out where they live.
