The invention relates to a frequency generating apparatus. More specifically, the invention relates to a frequency generating apparatus for treating a human or animal body by suppressing a disease causing organism within the human or animal body by subjecting the organism to specific frequencies. The frequency generating apparatus includes an integrated circuit capable of generating a range of frequencies and/or cycle of frequencies, electrodes for exposing the frequencies to a plurality of subjects, individual timers for timing the exposure time of each of the subjects and notification means for notifying the subjects of the lapse of a preset amount of time. The main advantage of the frequency generating apparatus is it's capability of treating a plurality of subjects simultaneously and without interference to each other regardless of when any of the subjects enter and/or exit the treatment.
