Item The composition, geographical variation and antimicrobial activity of Lippia javanica ( Verbenaceae ) leaf essential oils(2003) Subramoney, SivanasenLippia javanica is a widely spread woody shrub and the major traditional use is reflected in its vernacular name; fever tea ' koorsbossie '. An infusion of the leaves is also used as a decongestant for colds and coughs. Infusions may also be used topically to treat scabies and lice A preliminary study indicated that the essential oil chemistry varies dramatically both within and between natural plant populations.Item The antimicrobial activity and Phytochemistry of leaf essential oils of selected rutaceae species(2002-07) Khusal, PristishThe Retuceae is an aromatic family of plants confined to the Fynbos biome in South Africa. This family is represented by a number of genera e.g. Agasthosma, Adenandra, Coleonema, Vepris etc. all containing a number of species which have been used for centuries in traditional healing. Although many of these species have been used for centuries in local healing rites the biological activity and phytochemistry are poorly recorded.Item The composition and antimicrobial activity of leaf essential oils of selected agathosma species ( rutaceae )(2003-11-14) Fourie, CarlaThis project was conducted to investigate properties and to record the essential oil profiles of a selection of species belonging to the genus agasthosma. Plants have been used for many years by the local South African to treat various infections and illnesses. This knowledge has largely been untapped. Buchu is one of the plant species that are used extensively by the San and Khoi people. It is remarkable that of the ca. 150 agathosma species indigenous to South Africa only two species ( Agasthosma crenulata and agathosma betulina ) have been investigated for biological activity. The genus Agasthosma is traditionally used for the following conditions ; stomach ailments, fever, coughs, cold, flu, urinary tract, and kidney infections, haematuria, prostatitis, rheumatism, gout, bruises and for antiseptic purposes.
