The zapper is powered by a nine-volt battery. This voltage is too small, to harm you. In her book, “The Prevention of all Cancers”, Dr. Clark mentions that no effects on blood pressure, mental alertness, or body temperature have been noticed. It has never produced pain, although it has often stopped pain instantly. It is however advised not to zap if you are pregnant or wear a pacemaker as these conditions have not been researched yet. Children as young as eight months or even less have been treated with the zapper, without observing any adverse effect. In the case of very small infants the potential benefits against the unknown risks should be taken into consideration.
