The valerian plant grows 3-4 feet tall, with feathery leaves and flat clusters of pinkish flowers. The whole plant smells unpleasant, including the root and any products made with it. Valerian plants are usually found in wet conditions, but not always. Valerian root is often used as an herbal tea, which can be very relaxing (but should not be used by pregnant women). Cats are sometimes attracted to valerian, much like cat nip.
Latin: Valeriana officinalis
Common names: All-heal, St. George's Herb, Set Well, Vandal Root, Cat's Valerian, English Valerian, Amantilla
Using in rituals
Valerian is one herb that is most often used by Pagans for its medicinal properties rather than its magickal ones. Tea made from valerian can be a great relaxer before meditation. You'll need some sugar or honey to mask the taste.
Don't let the funky smell fool you. Valerian is used for love magick, as well as for protective rituals. Unfortunately, your typical charm bag type of love spell won't work with valerian. Carrying this stinky herb with you will harpoon any attempts to find your true love. Valerian is also used to promote dreams and other forms of sleep magick.
For both mundane or magickal purposes, its the root of the plant (either whole or powdered) that is used.
If you plan on using valerian, I suggest an extremely airtight container or your whole home will smell. I speak from experience.
