Herbs are used in magick for their "vibrations" or "essences". What does this mean? Herbs, like people, have gender, are ruled by a planet, an element, and sometimes, are sacred to a certain deity. Another reason to use herbs in magick is diversity. You can burn them as incense and make special incense blends to compliment your needs. You can use the essential oils in cleansing baths and anointing oils. You can even use them culinary for special ritual foods or magickal dishes.
