"S. media" contains plant chemicals known as saponins, which can be toxic to some species when consumed in large quantities. Chickweed has been known to cause saponin poisoning in cattle. However, as the animal must consume several kilos of chickweed in order to reach a toxic level, such deaths are extremely rare.Uses
