History

Wild lettuce is a legal ethno botanical in the United States, and has enjoyed a surge of popularity as a recreational herb on the internet. It is related to common garden lettuce Lactuca sativa, but the leaves are very bitter. The scientific name for wild lettuce, Lactuca virosa, relates to part of the plant’s physiology. If you scrape the leaf or stem of the plant, it immediately ejects milky white latex, and the name lactuca comes from the Latin word for milk, as in lactation. Wild lettuce leaves contain a potent milky latex, sometimes called "lettuce opium”, which is a sedative. The plant is also known as the compass plant as its leaves change direction to follow the sun. Since early ages, antecedents of the wild lettuce have enjoyed a special status as a beneficial therapeutic plant and were treasured as a tranquilizer and pain killer. The herb valued so much that during the 19th century people used it as a substitute for opium. The story goes that Roman emperor Augustus supposedly constructed a statue of a physician who had recommended lettuce to treat him of a serious ailment.
