DIVERSIDAD GENÉTICA Y MEJORAMIENTO DE PLANTAS MEDICINALES= Medicinal plants and improvement of medicinal herbs:

The experiment of RAPD molecular marker was conducted on 6 merit selections of Cynodon dactylon (L.) Pers. in China. 438 bands were amplified by 15 primer sequences, 415 polymorphic bands were produced, average 29 bands from each primer, average percentage of polymorphic band of 6 selections reached to 59.02%-75.49%. The genetic similarity coefficients among 6 selections were obviously different (0.408-0.672). The results suggested that there is abundant genetic diversity among different selections on DNA level. Compared with the new cultivar C106, the other selections can be improved further. Besides, the results also proved that the RAPD molecular marker can be successfully used to research the genetic diversity and new variety identification of C. dactylon.

Folk medicinal uses

In some parts of the Island, at least, a tea made by boiling the roots is thought to be good for the kidneys. It is used in the Transvaal by Europeans for indigestion and wounds.

Folk medicinal uses

This species has, in the past, been substituted for couch grass (Agropyron repens Beauvois) which was at one time official in the pharmacopoeias: it was used as a demulcent diuretic. The Cuban Flora states that bahama grass is diuretic and in both India and Jamaica the plant is considered to be a cold and fever remedy. We have also been told that the whole plant including the soil clinging to the roots makes an "acclimatisation tea" which should be drunk on moving to a new part of the island. This seems to be an extension of the fairly common practice on removal to a strange place of taking a small quantity of soil from below the surface, mixing it with water, leaving to settle and drinking the water.
