Caption:
This photograph depicts a sprig of violet-colored larkspur flowers of the genus Delphinium. All parts of the plant contain toxic diterpenoid alkaloids, including methyllycaconitine (MLA), a compound known to be poisonous to livestock. MLA blocks neuromuscular transmission in skeletal muscle, though not in smooth muscle. Through its neuromuscular blocking and cardiotoxic effects, ingestion of larkspur may result in rapid onset of paralysis and, in severe cases, death within a few hours.
