Ethnomedicinal Applications, Phytochemistry, and Pharmacological Properties of Zanthoxylum caribaeum Lam.: A Comprehensive Review

Zanthoxylum caribaeum Lam. is a member of the Rutaceae Family that can be naturally found in South and central America (Brazil, Paraguay, Bolivia, Caribbean, etc.). Its traditional medicinal uses are well documented among native communities, such as that of the Guarani, in Paraguay. More than 60 metabolites, including alkaloids, terpenoids, coumarins, and alkylamides, have been identified in its leaves, bark, and fruits. The biological activities and mechanisms of action of several of these compounds, as well as those of crude extracts, have also been investigated by previous studies. As a medicinal and edible plant, Z. caribaeum shows promising applications in the pharmacological industry. For the last 25 years, a significant amount of research has been conducted with Z. caribaeum to better understand its toxicity and complex mechanisms of action, bringing science-based clinical safety to its traditional uses. This review integrates available knowledge chemical and biological data on this species. It emphasizes the diversity of bioactive metabolites, their associated bioactivities, and provides an updated overview of the plant’s advances in ethnopharmacology, phytochemistry, pharmacology, agricultural exploitation, and potential utilization.
