摘要：This review aims to update the toxic plants that affect horses in Brazil. Currently, it is known that there are at least 131 toxic plants in the country belonging to 79 genera. Pseudocalymma elegans, Baccharis coridifolia, Panicum maximum, Ricinus communis, Prosopis juliflora, Diospyros virginiana, Crotalaria retusa, Senecio brasiliensis, Trema micrantha, Ateleia glazioviana, Bambusa vulgaris, Coffea canephora, Equisetum spp Hypochaeris radicata, Pteridium aquilinum, Sida carpinifolia, Turbina cordata, Senna occidentalis, Brachiaria spp., Froelichia humboldtiana, Brachiaria humidicola, Leucaena leucocephala, Allium cepa, Crotalaria juncea and Mimosa spp. are the main plants so far that cause poisoning in this species. The incidence of plant poisoning in horses is still low compared with other animals, due to their selective taste, except in cases where the animals are hungry in conditions of malnutrition or accidentally. Therefore, it is important to consider plant intoxication as the differential diagnosis of many other diseases in the country.
