Goldenrod is one of 125 species, all of which are found in the Americas with the exception of several found in Asia and a smaller number that have adapted to the cooler climate of Europe. It is a perennial plant, growing to about thirty inches with toothed leaves and branched spikes of golden yellow flowers. It prefers open areas and hillsides. The European species are not as potent, but still are used almost exclusively there because of its availability. The aerial parts are collected during the flowering season.
The herbalist, John Gerard, wrote in 1597 that the herb was the best one to be used to stop the bleeding of wounds.
Native Americans have long used the herb in treating urinary calculi. The Chippewa chewed the dried roots to relieve sore throats, while the Zuni chewed the crushed blossoms for the same reason. The Chippewa drank a decoction made from the roots to treat lung problems. It was used by the Thompson, Okanagan, and other tribes to treat diarrhea. Poultices made from the flowers have been used to treat burns and skin ulcers. The Chippewa applied warm compresses made by boiling the stalk or root to treat sprains or strained muscles.
