Useful information about the plant

Plantain is found in all temperate climates around the world and mainly grows in meadows and pastures, often on roadsides and ruderal like rubble piles. The genus name Plantago, derived from Latin "planta" (= foot sole, foot face) with the common suffix of plants "ago" refers in part to the flat, oval leaves of the plantain (P. major) lying closely on the ground in rosettes, on the other hand that the plantain is formed by being trampled by feet. The long-lanceolate and typical parallel leaves of the plantain are referred to in the epithet lanceolata (from the Latin "lanceolata" = small lance). They are numerous in a basal rosette, about 20 inches long and in comparison with the leaves of the plantain they are partly erect. The small flowers are in dense, cylindrical spikes at the end of long leaves standing out from furrowed scapes. They flower from bottom to top, which is easy to recognise from the yellowish white stamens outstanding from the corolla. Flowering period is May to September.

Medicinally used plant parts (drug)

The leaves and scapes are used whole or crushed. The commercial drug is mostly from farms in Eastern European countries and a small part of Holland.
