The common nettle comes by its other name, stinging nettle, honestly. The innocuous plant, a perennial that grows in many parts of the world and that has been naturalized to Brazil, delivers a stinging burn when the hairs on the leaves and stems are touched. Its healing properties are as well known among various cultures and are part of folklore and tradition. Those healing powers are even alluded to in at least one fairy tale, The Wild Swans, in which the heroine must weave shirts of nettle leaf to cure her eleven brothers who have been turned into swans by an evil stepmother. The nettle leaf and root both have medicinal properties, but each is more effective against different complaints. Nettle leaf is used traditionally as a diuretic, and as a treatment for rheumatism and arthritis. In Germany, a standardized extract is sold for the treatment of inflammatory conditions and prostate diseases. Nettle leaf’s effectiveness against rheumatism and other inflammatory diseases is well documented, and borne out by chemical analysis of the plant.
