The Ministry of Health has long stipulated that only regular drugs and medical drafts that have passed quality inspection and certification can inform patients of their therapeutic effects, and pay attention to whether drugs are health care products, medical devices or health care devices. All health care products can't replace medicines, let alone treat diseases.
All regular manufacturers of health care products and health care devices (such as melatonin) will never tell consumers that their products can cure diseases. Therefore, it can be said for sure that the universal water purifier of the times may have a certain effect on purifying water quality, but in fact, drinking more water from his home is no different from drinking more ordinary boiled water.
