Is lavatera poisonous to horses. Once cut is the toxic sap a danger to horses and cattle?

Lavatera, commonly known as mallow, is not considered toxic to horses. However, while the plant itself poses minimal risk, any potential danger typically comes from the sap or other plant parts if ingested in large quantities. It's advisable to monitor grazing areas for any plants that could be harmful to livestock, as individual animals may have different sensitivities. If you suspect any adverse effects, it's best to consult a veterinarian.
