Plantago major (broadleaf plantain, or greater plantain) is a species of flowering plant int the plantain family Plantaginaceae. The plant is native to most of Europe and northern and central Asia, but has widely naturalised elsewhere in the world.

Plantago major is one of the most abundant and widely distributed medicinal crops in the world. A poultice of the leaves can be applied to wounds, stings, and sores in order to facilitate healing and prevent infection. The active chemical constituents are aucubin (an anti-microbial agent), allantoin (which stimulates cellular growth and tissue regeneration), and mucilage (which reduces pain and discomfort). Plantain has astringent properties, and a tea made from the leaves can be ingested to treat diarrhea and soothe raw internal membranes.
