Foi realizada a análise morfo-anatômica da raiz de Waltheria douradinha St. Hil., estabelendose
parâmetros no controle botânico de qualidade da droga. A raiz axial e rugosa, de estrutura poliarca,
apresenta casca esfoliativa em semi-circulos e súber pluriestratificado com paredes anticlinais coincidentes.
O parênquima possui idioblastos com drusas, cristais prismáticos e grãos de areia. Constatou-se a presença
de mucilagens nos raios intraxilemáticos, cardioativos no cilindro central e alcalóides no córtex e cilindro
central.
