To provide a method of improving an existing product and facilitating the production of a novel product by the stimulus and reaction of electric energy such as negative charge (electron) on a living body or a plant (food), as well as a means for inhibition of oxidation and reduction by the improvement and facilitation of the living body resulting from the reductive material denaturation of the living body.

A method of using negative charge and positive charge separately by the electric power, which means a method of effectively utilizing their respective characteristics, is provided. For example, negative charge (electron) is used mainly for the oxidation and reduction, and the positive charge is used for improving the soil or the quality of water by propagating microbes by utilizing positive taxis stimulation. In addition, a stand-by method for inducing and applying the charge retained in the cathode and anode to separate metal bodies (charged bodies) via lead wires, or a stand-by method for applying the charge to a metal part of a target existing product, is provided. On the other hand, the electron is a particle constituting an atomic nucleus, though the electron (negative charge) is a characteristic particle which is said to be "likely to wander or capricious". Accordingly, the property of the electron to adhere to or separate from other atoms is a cause of the "oxidation and reduction" of an object. The method is characterized by utilizing the property of the electron and the retained electronic charge.
