Plantago major is a species of Plantago, family Plantaginaceae. The plant is native to most of Europe and northern and central Asia. It is widely naturalised elsewhere in the world, where it is a common weed. As a result, it has many common names. The standard native English name is Greater Plantain, though it is also called Common Plantain in some areas where it is introduced, particularly North America. Another one of its common names was "Soldier's Herb" for its use on the battlefield as a field dressing.
Plantagomajor L. leaves have been used as a wound healing remedy for centuries in almost all parts of the world and in the treatment of a number of diseases apart from wound healing. These include diseases related to the skin, respiratory organs, digestive organs, reproduction, the circulation, against cancer, for pain relief and against infections. P. major contains biologically active compounds such as polysaccharides, lipids, caffeic acid derivatives, flavonoids, iridoid glycosides and terpenoids.
