[6] Poisonous plants are more of a danger to livestock after wildfires, as they often regrow more quickly. [7]

Ingestion of silverleaf nightshade has been implicated as a cause of ivermectin toxicosis in horses given the recommended dosage of the drug. Metabolites from the plant are speculated to disrupt the blood–brain barrier , allowing ivermectin to enter and disrupt neurotransmitter function in the brain and spinal cord.
