Amaranthus graecizans subsp. silvestris (Vill.) Brenan, a medicinal herb belongs to family Amranthaceae. Pharamcognostical and physicochemical characterization of A. graecizans subsp. silvestris which included; macro and microscopic evaluation, phytochemical and physicochemical analysis of leaf, stem, root, fruit and seeds was investigated. Transverse sections of leaf, stem and root showed the arrangement of different cells, certain tissues that will serve as diagnostic characters to standardize this plant. The powder microscopy of leaf, stem, root, fruit and seed depicted various microscopic structures including; fibres, vessels, tracheids, oil cells, starch granules, cortical cells, cork cells, phloem, collenchyma and parenchyma tissues etc. In fluorescence analysis different colors were seen when extracts were exposed to ordinary and UV light. Phytochemical screening of methanolic extract of whole herb exhibited the occurrence of saponins, tannins, carbohydrates, flavonoids, cardiac glycosides, sterols, lipids and alkaloids. Physicochemical analysis i.e. extractive values and ash values were calculated to strengthen standardization process. These findings and estimations will help in characterization, verification and quality maintenance of A. graecizans subsp. silvestris
