Natural remedies, such as medicinal plants, have been used since ancient times to treat a variety of symptoms, including pain. Wild lettuce (Lactuca virosa) is native to many areas of the world, including North America, Europe and the Middle East. This herb thrives in sunny locations, such as along riverbanks and roadsides, and can grow up to six feet (1.8 meters) in height. Wild lettuce has bright green leaves which sprout from a green stem that is occasionally spotted purple. When scratched, the plant secretes a milky, white substance known as lactucarium. Lactucarium contains lactucin and lactucopicrin, bitter substances that act on the central nervous system to produce pain-relieving and sedative effects. Wild lettuce is a plant known for its pain-relieving properties. It is utilized by people interested in alternatives to conventional medications. Though wild lettuce has been used since ancient times to treat pain, very little evidence supports its use in humans.
