Uses of a multipolar microkinetic drinking water in preparing a drink, healthcare product or medicament for reducing blood urea. The multipolar microkinetic drinking water is prepared from raw drinking water being passed through an electromagnetic wave without contact. Compared with the raw drinking water, the ultraviolet absorption peak is offset by 25 nm to 40 nm, where the preferred offset is 28 nm to 30 nm, and the optimal offset is either 30 nm or 28 nm.
