The inherent danger within the vast *Astragalus* genus is highlighted by certain species that pose significant health risks to animals. Specifically, species colloquially known as locoweeds, which are scientifically classified as *Astragalus* varieties, are notorious for the adverse effects they cause when consumed by grazing livestock.
