The invention relates to a device that is simple to operate, for reducing pathogenic microbes using the antimicrobial effects of silver ions, without engaging additional medicinal treatment, for effectively treating the human body in case of illness or as a preventive measure. The aim is achieved by a device comprising a handle, a negative pole coming into contact with the body, and a device head having a positive pole, so that a low electrical voltage is generated between the poles, wherein at least the positive pole is made of silver, giving off positive ions into the body tissue when the circuit is closed.
