The objective was to describe information about the species of Ipomoea and their relationship with animal poisoning, through concepts about clinicopathological and preventive aspects. A narrative review was carried out using keywords “neurotoxic plants”, “animal intoxication”, “Convolvulaceae”, “Ipomoea”, “lysosomal storage”, “tremorgenic syndrome” by consulting the databases Google Scholar, SciELO, PubMed, Elsevier and capes journals. Searches were limited to the period between January 1997 and February 2023, in Portuguese and/or English. The selection of studies was carried out by the authors, independently, by reading the title, abstract and full text. The synthesis process took place in two guiding axes: Ipomoea species and animal intoxication. Some species of Convolvulaceae are toxic to livestock, the genus Ipomoea is the largest botanical class of the family, they may contain swainsonine and/or calystegines, cases of intoxication occur due to the scarcity of pastures in the dry period, right after the rains, these plants regrowth, animals ingest and develop clinical signs, with neurological changes related to the storage of oligosaccharides and reproductive problems. The study of the epidemiology, clinical signs and pathology of intoxications that compromise the nervous system, contributes to the prophylaxis and control of intoxications, in addition to the differential diagnosis. The amount of ingested material and the time of exposure to the toxin are determining factors for outbreaks of animal poisoning. It is concluded that the genus Ipomoea brings together toxic plants with relevant epidemiology, clinical and economic outcome in ruminants due to the variability of species and concentrations of their toxic principles.
