This is a scam. Drinking water can't cure diseases in most cases. Water is an important part of the normal physiological function of the body. By replenishing water, we can prevent some diseases, but in most cases, water can't be used to treat diseases like pills. For example, for osteoporosis, leukemia, lymphoma and depression, water can hardly play any therapeutic role. Take leukemia and lymphoma for example. They are diseases caused by leukemia. This mutation may be caused by external factors or internal gene mutation, and it cannot be treated by drinking water alone. If water is used to treat a disease, it is tantamount to "roasting a tumor with fire", which is counterproductive. It will not only cure the disease, but also delay the best treatment time of the disease.
