Stinging Nettle plant 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 nettles 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.

Stinging Nettle Cream for Osteoarthritis
In this study, researchers prepared the stinging nettle plant in a topical cream
and had 23 patients with radiologically confirmed osteoarthritis apply the cream
twice daily for 2 weeks. Western Ontario and MacMaster Universities
Osteoarthritis Index (WOMAC) short-form assessments, measuring functional
status, were conducted at baseline and at week 2. After 2 weeks’ treatment,
there was a mean reduction (representing improved function) of 4.1 in WOMAC

nettle could prove beneficial to patients with osteoarthritis for pain relief
and disease process modification.
