These naturally produced toxic alkaloids in the plant can cause poisoning if ingested by humans, dogs, cats, or horses. Vinca plants are safe when handled and do not cause any harm when touched. It is best to wash your hands after planting or pruning to remove any toxins that you may have come in contact with.
