Argemone

a genus of the plant family Papaveraceae, the poppy family. Includes A. mexicana, A. ochroleuca, A. subfusiformis; contains isoquinoline alkaloids including sanguinarine, which causes mucosal irritation and also interference with pyruvate oxidation in brain tissue. The sanguinarine is excreted in cows' milk and may be linked to the occurrence of endemic primary glaucoma of humans. The seeds of A. mexicana and A. ochroleuca are frequent contaminants of grain fed to chicken, causing low egg production, edema, ataxia, comb cyanosis and gastroenteritis. Dried plants in hay may cause chronic heart failure in cattle. Called also Mexican poppy.
