Some medicinal plants that are indigenous to the United States are Echinacea also known as Purple Coneflower, Lobelia, and Evening Primrose to name a few. Echinacea grows in humid or dry prairies and in open wooded areas. Lobelia grows mainly in regions with temperatures ranging from sultry to warm, while a few species can also grow in cooler temperate regions. Evening Primrose can be found in a diverse range of environments including sand dunes, roadsides, railway embankments, and waste areas, thus it can be drought-resistant. Some popular oil exports that originate in the United States include Wheatgerm and Oat carrier oils and Cedarwood essential oil.
