It was distributed worldwide for its beauty and grown for ornamental purposes in gardens.
Sweet Pea Toxic Components
Sweat pea contains β-aminopropionitrile (BAPN), which is a toxic amino-acid derivative. If ingested, the toxin causes a poisoning syndrome known as lathyrism. Lathyrism is a paralysis syndrome. Horses develop clinical signs from consumption of large quantities of L. odoratus
over a long period of time. Once signs develop however, they are irreversible, other then surgery might correct roaring.
