East African quintessential plants claimed to be used as blood purifiers, cleansers, detoxifiers and tonics: an appraisal of ethnobotanical reports and correlation with reported bioactivities

Abstract

The search retrieved 74 plant species from 45 families distributed among 66 genera with some documented bioactivities, though, with little correlation with their traditional utilization in blood purification, cleansing, detoxification and strengthening. Some justification of the link between blood purification, cleansing, detoxification and strengthening and the use of the plants as antiplatelet aggregation, vasorelaxant, bronchodilatory, antihyperlipidaemic, cardioprotective, antiatherosclerotic and immunomodulatory agents were evident, but majorly antimicrobial activity has been investigated in most species. Thus, only 15 (20.2%) of the plant species (Allium sativum, Moringa oleifera, Olea capensis, Clausena anisata, Centella asiatica, Nasturtium officinale, Solanum nigrum, Withania somnifera, Rubus apetalus, Delonix elata, Persia americana, Aloe vera, Azadirachta indica, Echinacea angustifolia and Dioscorea bulbifera) could be directly correlated with studies pertaining to blood health.
