Abstract
Objective: The study of 11 plants used in the treatment of Bilharzia in Côte d'Ivoire aims to highlight their anatomical-histological structures. Methods: The anatomical study of these plants was carried out on the stems by the classical method of staining the tissues with carmine-green. Results: This staining technique made it possible to distinguish two groups of tissues. Those with a pink stained cell wall (cellulose wall cells) and those with a green stained lignified cell wall. From the periphery to the interior of the organs, we observe the epidermal hairs, the epidermis, the collenchyma, the cortical parenchyma, the sclerenchyma (for aged or more or less aged tissues), the liber or phloem, the wood or xylem and the medullary parenchyma. Conclusion: The carmine-green staining made it possible to distinguish different plant stem tissues, arranged according to the colouring, structure, shape and size of the cells in each tissue.
