Some studies have shown that male patients can prevent prostatitis to some extent by taking flavonoid supplements appropriately. Flavonoids are a class of plant secondary metabolites that are widely found in plants and are the active ingredients of many herbal medicines. Flavonoids, which need to be extracted by alcohol extraction method, microwave extraction method and other methods, are made into health supplements with weak estrogenic effects, which may prevent prostatitis in men, probably because of the antioxidant effects of flavonoids. Flavonoids need to be taken under the guidance of a professional doctor, so as not to cause adverse consequences or lead to the aggravation of the patient’s condition.
