Plantago Pusilla

''Plantago'' is a genus of about 200 species of flowering plants in the family Plantaginaceae, commonly called plantains or fleaworts. The common name plantain is shared with the unrelated cooking plantain. Most are herbaceous plants, though a few are subshrubs growing to tall.

Description

The leaves are sessile or have a poorly defined petiole. They have three or five parallel veins that diverge in the wider part of the leaf. Leaves are broad or narrow, depending on the species. The inflorescences are borne on stalks typically tall, and can be a short cone or a long spike, with numerous tiny wind-pollinated flowers.

Species

The boundaries of the genus ''Plantago'' have been fairly stable, with the main question being whether to include ''Bougueria'' (one species from the Andes) and ''Littorella'' (2–3 species of aquatic plants).Albach, D. C., Meudt, H. M. & Oxelman, B. 2005

Etymology

The genus name ''Plantago'' descends from the classical Latin name , which in classical Latin meant some ''Plantago'' species, including ''Plantago major'' and ''Plantago media''. In Latin the name was formed from the classical Latin word = "sole of the foot". The name was so formed in Latin because the leaves of these species grow out near flat at ground level. The suffix in Latin means "a sort of".

Distribution and habitat

The species are found all over the world, including the Americas, Asia, Australia, New Zealand, Africa and Europe. Many species in the genus are cosmopolitan distribution, cosmopolitan weeds. They are found in many different habitats, most commonly in wet areas like seepages or bogs. They can also be found in alpine and semi-alpine or coastal areas. The cosmopolitan weeds can be frequently seen at the side of roads.

Ecology

Plantains are used as food plants by the larvae of some species of Lepidoptera (butterfly and moth).

Uses

Plantain has been consumed as human food since prehistory. For example, archaeological recovery along California's Central Coast has demonstrated use of this species as a food since the Millingstone Horizon. The broad-leaved varieties are sometimes used as a leaf vegetable for salads, green sauce, and so on. Tender young plantain leaves can be eaten raw and older leaves can be cooked. The seeds can be cooked like rice.

''Plantago'' species have been used since prehistoric times as herbalism, herbal remedies. The herb is astringent, anti-toxin, toxic, antimicrobial, anti-inflammatory, anti-histamine, as well as demulcent, expectorant, styptic and diuretic. Externally, a poultice of the leaves is useful for insect bites, poison-ivy rashes, minor sores, and boils. In folklore it is even claimed to be able to cure snakebite and was used by the Dakota Indian tribe of North America for this. Internally, it is used for coughs and bronchitis, as a tea, tincture, or syrup. Tea made from the leaves may help cure diarrhea.

Psyllium seed husks, Plantain seed husks expand and become mucilaginous when wet, especially those of ''P. psyllium'', which is used in common over-the-counter bulk laxative and fiber supplement products such as Metamucil. ''P. psyllium'' seed is useful for constipation, irritable bowel syndrome, dietary fiber supplementation, and diverticular disease. Mucilage from Plantago ovata, desert indianwheat (''P. ovata'') is obtained by grinding off the husk. This mucilage, also known as psyllium, is commonly sold as Isabgol, a laxative which is used to control irregular bowel syndrome and constipation. It has been used as an indigenous peoples, indigenous Ayurvedic and Unani medicine for a whole range of bowel problems. Psyllium supplements are typically used in powder form, along with adequate amounts of fluids. A dose of at least 7 grams daily taken with adequate amounts of fluid (water, juice) is used by some for management of elevated cholesterol. There are a number of psyllium products used for constipation. The usual dose is about 3.5 grams twice a day. Psyllium is also a component of several ready-to-eat cereals.

In Serbia, Romania, Bulgaria and Russia, leaves from ''Plantago major'' are used as a folk remedy to preventing infection on cuts and scratches because of its antiseptic properties. In Slovenia and other Central European regions, the leaves were traditionally used topically as a cure for blisters resulting from friction (such as caused by tight shoes etc.).

There may also be a use for plantains in the abatement of enteric methane from ruminants, as the natural compounds present (e.g. condensed tannins; ~14 g/kg DM), affect the acetate-propionate ratio in the rumen, which is a primary mechanism by which methanogenesis is restricted.Lourenço, M., G. Van Ranst, B. Vlaeminck, S. De Smet, and V. Fievez (2008). "Influence of different dietary forages on the fatty acid composition of rumen digesta as well as ruminant meat and milk", Animal Feed Science and Technology, 145(1-4), 418–437. Currently this is not a viable option in any significant scale due to agronomic difficulties.

Culture

As Old English ''Wegbrade'' the plantago is one of the nine plants invoked in the Anglo-Saxon paganism, pagan Anglo-Saxon ''Nine Herbs Charm'', recorded in the 10th century.
