Estrogenic properties of locoweed (Astragalus lentiginosus).

Canadian journal of comparative medicine : Revue canadienne de medecine comparee, 1973
Locoweed, Astragalus lentiginosus was extracted with ether (EE) and water (WE). These and the plant residue were mixed with basal diet (BD) and fed to weanling female mice to determine the plant's estrogenic activity. Diethylstilbesterol (DES) was fed as a control. Uterine weight was taken at five to seven days. Three feeding trials were conducted.

Astragalus bisulcatus--a cause of selenium or locoweed poisoning?

Veterinary and human toxicology, 1983
Certain plants accumulate selenium at levels that render them toxic. One of the principle groups of selenium-accumulating plants is the selenium-accumulating Astragalus.
