[ ] a few pharmacological role ( male child more) in eating beans or inhalation of its pollen, can produce acute hemolytic anemia ( a broad bean flavivirus Favism ), symptoms of hemoglobinuria, shock, fatigue, dizziness, gastrointestinal disorders and urinary urobilinogen excretion increased; more severe with pale, jaundice, vomiting low back pain, weakness.

Occurrence of broad bean yellowing reasons, is one of the few people to have a congenital biochemical defect, namely the blood cells in the absence of glucose - 6 - phosphate dehydrogenase ( G-6-PD ), so the reduced glutathione content is very low, in vicine after invasive, can produce blood cell lysis. Will vicine blended in a food ( l% ) on rat or chick can inhibit their natural growth. Some people also believe that, in addition to vicine, beans and other factors can also cause a similar hemolysis. The root contains5 hydroxy - uracil, as a metabolic antagonist, and containing2,6- two amino purine ( DAP ), can suppress lactobacillus, this inhibition can be gland glucoside by turnover: the material can make the bone marrow depletion, and hurt the dog and rat colon, jejunum epithelial cells, is a carcinogenic substance. The role of DAP is not through the pentose nucleic acid ( PNA ), but due to the interference of the gland glucoside, guanidine essential metabolic functions.
