Evaluation of Immunotoxic Properties of Senecio brasiliensis: Study of Toxicity in Rats

摘要

More than 1200 species of plants from genus Senecio are cataloged worldwide, and S. brasiliensis is the most important species in Brazil. Plants from this genus have frequently been associated with poisoning in livestock such as cattle, horses (Tokarnia et al. 2000), sheep (Ilha et al. 2001), and Murrah buffalo (Correa et al. 2008). About 50% of all deaths caused by toxic plants in cattle in southern Brazil and Uruguay are due to the consumption of Senecio spp., therefore this plant causes large economic losses for farms and ranches in the region (Karam et al. 2004).
