Lupinus perennis

Safety & Hazards

Lupinus species in general (and especially the seeds) contain a range of bitter-tasting alkaloids such as lupine, anagyrine, sparteine and hydroxylupanine. The pharmacological effects of these alkaloids are that they block ganglionic transmission, decrease cardiac contractility and contract uterine smooth muscle[ 299 Title Protabase - Plant Resources of Tropical Africa.

Alkaloid levels can vary greatly from species to species, and several members of the genus are used for food. In some species low-alkaloid, sweeter-tasting varieties have been developed. There are also techniques (particularly soaking and discarding the soak water) that lower the alkaloid levels. Unless it is known that the plant is low in alkaloids then caution should be applied to any ingestion of the plant[ K Title Plants for a Future Author Ken Fern Description Notes from observations, tasting etc at Plants For A Future and on field trips. ].
