Mung beans themselves do not have toxins and do not cause poisoning directly after eating them. However, if you eat uncooked mung beans, leave them for a long time after cooking, or eat a large amount of mung beans at one time, you may experience symptoms similar to poisoning, manifested as abdominal distension, nausea, vomiting, or gastrointestinal symptoms such as abdominal pain and diarrhea. In addition, the abdominal pain is mainly paroxysmal colic, which may be persistent and aggravated by paroxysms. In addition, symptoms of the central nervous system may appear, such as general weakness, dizziness, nausea, or uncoordinated arms and legs, blurred vision, etc. The symptoms will be gradually relieved by appropriate rest and symptomatic treatment.
