If you don't grow any medicinal plant in your garden at least grow nettles.Of course it is a weed, but aren't most of our most powerdul medicinal herbs weeds?
The uses of nettles include: treat painful muscles and joints, eczema, arthritis, gout, and anemia. Today, many people use it to treat urinary problems during the early stages of an enlarged prostate. It is also used for urinary tract infections, hay fever, or in compresses or creams for treating joint pain, sprains and strains, tendonitis, and insect bites. I find that tea made out of fresh nettle leaves tastes mush better than out of dried leaves.
Apart from being a medicine, young nettles can be used in every recipe that calls for spinach.
In the garden, nettles make a great liquid fertilizer. The nutrients in stinging nettle fertilizer are those same nutrients the plant contains which are beneficial to the human body such as many minerals, flavinoids, essential amino acids, proteins and vitamins. A nettle leaf plant food will have: Chlorophyll, Nitrogen, Iron, Potassium, Copper, Zinc, Magnesium and Calcium.
I offer the European nettle.I don't know about the medicinal qualities of the native nettles, but their sting is fierce compared to the European nettles.
