In an attempt to scientifically appraise the ‘healing powers’ and medicinal value of Harpagophytum procumbens DC root aqueous extract (HPE), and throw some light on the efficacy and safety of the medicinal plant product, the cardiovascular effects of the herb’s root aqueous extract (HPE) have been investigated in some mammalian experimental animal models. The results of this laboratory animal s...

Recent studies all indicated that both the affinities and subdivision of Boraginaceae s.str. are unsatisfactorily resolved. Major open issues are the placement and affinities of Boraginaceae s.str. in Boraginales and the major clades of the family, with especially the large tribes Cynoglosseae and Eritrichieae repeatedly retrieved as non-monophyletic groups, and the doubtful monophyly of severa...

the therapeutic potential of crude extracts of aerial parts (stem, leaves and flowers) of tridax procumbens was screened for in vitro antioxidant potential and alpha amylase inhibitory action. the crude hydro-methanolic, aqueous and petroleum ether extracts were obtained by percolation-maceration method using 50% methanol, double distilled water and petroleum ether as solvents. phytochemical sc...
