044  Cynodon dactylon (L.) Pers.


Nome comune: Gramigna rampicante; Gramegna; Gramagna; Ramigna; Ramina; Ramaccia; Dente di cane; Capriola

C. dactylon is widely cultivated in warm climates all over the world between about 30 south and 30 north latitude, and that get between 6251,750 mm (24.669 in) of rainfall a year (or less, if irrigation is available). It is also found in the U.S. mostly in the southern half of the country and in warm climates. It is fast growing and tough, making it popular and useful for sports fields, as when damaged it will recover quickly. It is a highly desirable turf grass in warm temperate climates, particularly for those regions where its heat and drought tolerance enable it to survive where few other grasses do. It has a relatively coarse-bladed form with numerous cultivars selected for different turf requirements. It is also highly aggressive, crowding out most other grasses and invading other habitats, and has become a hard-to-eradicate weed in some areas. This weedy nature leads some gardeners to give it the name of "devil grass". Bermuda grass has been cultivated on saline soils in California's Central Valley which are too salt-damaged to support agricultural crops; it was successfully irrigated with saline water and used to graze cattle.[2][3] Cynodon dactylon has been studied at the University of Allahabad in India, and is said to have many medicinal properties including antimicrobial and antiviral properties, as well as treatment of urinary tract infections, prostatitis, syphilis, and dysentery.[4] Primarily the research being conducted on C. dactylon involves its glycemic potential, which is involved in the treatment of diabetes. The majority of research has only been performed on lab rats, but the results are interesting. In laboratory rats treated with the ethanolic extract of defatted C. dactylon, hypoglycemic and anti-diabetic results were observed on the blood glucose levels of the tested population.[4] Test populations showed nearly a 50% drop in blood glucose levels when the proper dosage was administered.[4] There is potential for Cynodon dactylon to become an alternative to current diabetes medications in the future.
