Various species of nettle grow throughout North America, and they all offer a wealth of medicinal benefits. Look for weeds growing 12 to 50 inches tall that are covered in hairs and have small green clusters of flowers. Collect these plants with care because of their stinging hairs, and boil the stems, leaves and roots to make a tea. Nettle tea can be used to treat congestion, stomachaches and diarrhea, and a decoction of nettle leaves can be used to clean infected wounds.
