People often use mung bean soup to rescue people who are poisoned by drugs or food. The detoxification function of mung bean is that mung bean protein, tannin and flavonoids in mung bean can combine with organophosphorus pesticides, mercury, arsenic and lead compounds to form precipitation, which reduces or loses toxicity and is not easily absorbed by gastrointestinal tract.

Because mung beans are cold, it is not advisable to take mung beans when taking warm tonic drugs such as ginseng, astragalus, cinnamon, aconite, clove and galangal, and traditional Chinese medicines such as cassia twig, dried ginger and asarum, so as not to reduce the efficacy and affect the therapeutic effect.
