Stinging Nettle (Urtica dioica) is a perennial herb with stinging hairs found in the United States mostly in forests, mountains, weedy, undisturbed areas and roadsides. Extracts of the stinging nettle roots have been used in Germany for the therapy of prostate disorders and rheumatoid arthritis . Extracts from stinging nettle contain a number of substances including caffeic acid, malic acid, polysaccharides and probably many other compounds including lectins, lignans, and phytosterols. Stinging nettle has been shown to be anti-inflammatory by preventing the body from making inflammatory chemicals known as prostaglandins. Stinging nettle’s root may affect hormones and proteins that carry sex hormones (such as testosterone or estrogen) in the human body; this may explain why it helps benign prostatic hyperplasia.
