Mung bean is both a food and can be used as a herbal medicine. It has the effect of clearing heat and detoxifying the body, promoting water retention and reducing swelling, but mung beans are not clinically useful as a potent, targeted detoxifier. Mung beans do have a certain detoxifying effect, and what works is mainly the mung bean protein in mung beans, which contains tannins and flavonoids, which can combine with some heavy metals such as organophosphorus pesticides and mercury to form precipitates, thus making them lose their toxicity and not be absorbed by the gastrointestinal tract. In addition, mung beans have some detoxification effect for some viruses, but the effect is limited. In the summer we often drink some mung bean soup, because the mung bean has the effect of detoxification, summer heat, water and swelling.
