Bermuda grass known as Dhoob, ethana grass, dubo, dog's tooth grass, Bahama grass, devil's grass, couch grass, Indian doab, arugampul, grama, wiregrass and scutch grass, is a grass now found worldwide. It is native to Europe, Africa, Australia and much of Asia. It has been introduced to the Americas. Although it is not native to Bermuda, it is an abundant invasive species there. In Bermuda it has been known as crab grass.
Bermuda Grass is a grass native to north Africa, Asia and Australia and southern Europe. The name "Bermuda Grass" derives from its abundance as an invasive species on Bermuda; it does not occur naturally there. The blades are a grey-green colour and are short, usually 4-15 cm long with rough edges. The erect stems can grow 1-30 cm, rarely to 3 ft, tall. The stems are slightly flattened, often tinged purple in color. The seed heads are produced in a cluster of 3–7 spikes (rarely two) together at the top of the stem, each spike 3–6 cm long. It has a deep root system. In drought situations with penetrable soil, the root system can grow to over 2 m deep, though most of the root mass is less than 60 cm under the surface. The grass creeps along the ground and root wherever a node touches the ground, forming a dense mat. Bermuda Grass reproduces through seeds, through runners and rhizomes.
The plant has been long used in the traditional medicines to treat various ailments such as anasarca, cancer, convulsions, cough, cramps, diarrhea, dropsy, dysentery, epilepsy, headache, hemorrhage, hypertension, hysteria, measles, rubella, snakebite, sores, stones, tumors, urogenital disorders, warts and wounds.
The rhizomes are reported to act as a diuretic in humans and the grass juice can act as an astringent. It has been observed that Bermuda Grass may be selectively eaten by dogs to swiftly induce vomiting when they have gastrointestinal problems. The effect may be due to irritation caused by bristles on the leaf margin.
