It is usually cultivated in the field or near the Bank of the field. It is planted in most parts of the country.

The stem (faba bean stem), leaf (faba bean leaf), flower (faba bean flower), pod shell (faba bean pod shell) and seed coat (faba bean shell) of this plant are also used for medicine. See special regulations for details.

[collection] when the pods are dark brown in summer, take the whole plant, dry in the sun, lay the seeds, and then dry in the sun.

[chemical constituents] the seed contains 0.5% of chaocaioside, 28.1-28.9% of protein, phospholipid, choline, piperidine-2 and plant lectin. Nestinin is a competitive inhibitor of glucose-6-phosphate, which is one of the causes of faba bean disease.

[pharmacological action] a few people (more boys and children) may develop acute hemolytic anemia after ingesting broad bean or inhaling its pollen. The symptoms include hematuria, shock, fatigue, vertigo, gastrointestinal disorder and increased excretion of urobilin; the more serious ones are pallor, jaundice, vomiting, low back pain and weakness. Generally, it occurs 5-24 hours after eating raw broad bean, but sometimes it can also occur when eating fried hot. If the Department inhales its pollen, then the attack is quicker. The reason of Faba Bean yellow disease is that a few people have a congenital biochemical defect, that is, the lack of glucose-6-phosphate dehydrogenase in their blood cells, so their reduced glutathione content is also very low. After the invasion of chaocaioside, blood cell lysis can occur. The natural growth of rats and chickens could be inhibited by the mixture of nestinin and food (1%). It was also suggested that there were other factors in Vicia faba that could cause similar hemolysis.

The root contains 5-hydroxyuracil, a metabolic antagonist, and 2,6-diaminopurine, which can inhibit Lactobacillus. This inhibition can be reversed by adenosine. The above substances can cause bone marrow depletion and damage the epithelial cells of colon and jejunum in dogs and rats. It is a carcinogen. The effect of DAP is not through pentose nucleic acid, but by interfering with the basic metabolic functions of adenosine and guanidine.
