The safety of many African traditional herbal remedies is doubtful due to lack of standardization.This study therefore attempted to standardize two polyherbal formulations from Ogbomoso, Oyo State, Nigeria, with respect to the relative proportions (weight-for-weight) of their botanical constituents. Information supplied by 41 local herbal practitioners was statistically screened for consistency and then used to quantify the composition of antimalarial (Maloff-HB) and haematinic (Haematol-B) powdered herbal formulations with nine and ten herbs, respectively. Maloff-HB contained the stem bark of Enantia chloranthaOliv. (30.0), Alstonia booneiDeWild (20.0),Mangifera indica L. (10.0),Okoubaka aubrevillei Phelleg &Nomand (8.0), Pterocarpus osunCraib (4.0), root bark of Calliandra haematocephalaHassk (10.0), Sarcocephalus latifolius (J. E. Smith) E. A. Bruce (8.0), Parquetina nigrescens (Afz.) Bullock (6.0), and the vines of Cassytha filiformis L. (4.0), while Haematol-B was composed of the leaf sheath of Sorghum bicolor Moench (30.0), fruit calyx of Hibiscus sabdariffa L. (20.0), stem bark of Theobroma cacao L. (10.0), Khaya senegalensis (Desr.) A. Juss (5.5), Mangifera indica (5.5), root of Aristolochia ringens Vahl. (7.0), root bark of Sarcocephalus latifolius (5.5), Uvaria chamae P. Beauv. (5.5), Zanthoxylum zanthoxyloides (Lam.) Zepern & Timler (5.5), and seed of Garcinia kolaHeckel (5.5). In pursuance o
