Zingiber officinale Roscoe is a rhizomatous plant widely used as an ethnomedicinal agent and food. Although its pharmacological properties are well-studied, histochemical studies are scarce. This study aimed to perform a histochemical analysis of the Z. officinale rhizome to characterize the histological localization of its nutritionally and pharmacologically important metabolites. Fresh rhizome sections were prepared for light microscope analysis using histochemical methods. The results revealed anatomical features of the rhizome and identified components of its primary metabolism, such as lipids, proteins, and starch, as well as secondary metabolites like phenolic compounds, terpenoids, tannins, sesquiterpenlactones, and alkaloids. These compounds are active principles responsible for the species' pharmacological properties. The analysis defined the anatomical location and distribution of ginger's bioactive compounds, which are essential for identifying products derived from the species.
