Golden-bean
General poisoning notes:
Golden-bean (Thermopsis
rhombifolia) is a native plant that is found in the southern part of
western Canada. This plant has been suspected since the late 1800s to be
poisonous to cattle and horses, but conclusive evidence is lacking in the
literature. The related plant, poison-bean (Thermopsis montana), causes
poisoning in cattle. Poison-bean contains several quinolizidine alkaloids, and
similar chemicals may be found in golden-bean. Ingesting seeds of golden-bean
was suspected in a case of poisoning of a child in western Canada. Until more
definitive studies appear in the literature, the plant is included in this
Information System because of its potential for poisoning (Kingsbury 1964,
Keeler et al. 1986).

Notes on Toxic plant chemicals:
The chemicals
listed here are found in the closely related poison-bean (Thermopsis montana),
although similar chemicals are found in golden-bean (Keeler et al. 1986). Some
of these chemicals are found in other members of the pea family, including
anagyrine, which causes teratogenic effects in cattle that eat lupines
containing this chemical.
Toxic plant chemicals:
Anagyrine, cytisine,
N-methylcytisine, thermopsine.
Animals/Human Poisoning:
Note: When an
animal is listed without additional information, the literature (as of 1993)
contained no detailed explanation.
