Sidou is a climbing vine of Leguminosae, also known as red bean, acacia and love bean. Growing in the south of China. Different from the red beans (adzuki beans) that we often eat in our daily life.

Acacia beans contain acacia venom protein, and contain acacia, sea bafulin, fenugreek and acacia acid. Acacia venom protein is highly toxic. Very low concentration can cause erythrocyte agglutination and hemolysis, which has a strong stimulating effect on mucosa and is toxic to other cells.

Sophora japonica beans are highly toxic, and you can die if you chew 2-3 pieces. Once eaten by mistake, it will cause nausea, vomiting, diarrhea, colic and other symptoms. After a few days, hemolysis appeared, characterized by dyspnea, cyanosis, weak pulse and weak heartbeat. In severe cases, people may die of coma, respiratory and circulatory failure and renal failure.

After eating locust bean poisoning, you should immediately induce vomiting, gastric lavage and catharsis, protect the gastric mucosa with milk and egg white, inject atropine and other antispasmodic painkillers into muscles, and make intravenous fluid replacement to correct the water-electrolyte disorder. Usually, it is necessary to publicize that locust beans are highly toxic and cannot be eaten. Acacia beans cannot be used instead of red beans when preparing traditional Chinese medicine.
