The best known species of nettle in North America is the stinging nettle, which has fine hairs that contain an acid solution. When you brush against the plant, these hairs break or get under your skin causing burning and irritation. Heating or boiling the leaves eliminates the acid and makes nettles safe for use. The plant is a perennial that grows in all manner of environments and is often considered a weed. Nettle is used in herbal teas, as a diuretic and for liver cleansing.
Latin: Urtica dioica among others
Common names: Stinging nettle, greater nettle, common nettle
There are several different species of nettle, all of which can be used in magick. Stinging nettle is usually what is found in herbal or magick stores.
Nettle is a protective herb that will help repel negative energy. The dried herb works well to protect your home and can also be carried in a charm bag when you are out. The capacity of fresh nettle to cause burning under the skin has brought about the association with passion and lust. I wouldn't recommend actually using fresh nettle for any love magick though. Ouch!
Folklore says that you should wear a sprig of fresh thyme when attending a funeral, to protect yourself from the sadness and grief of others.
The ancient Greeks used to burn thyme as a pleasant smelling incense, that they felt was invigorating.
