No, it was battery wave based. The frequency was entirely incidental.
Dr. Clark said:
Any positively offset frequency kills all bacteria,
viruses and parasites simultaneously given sufficient voltage (5 to 10 volts), duration (seven
minutes), and frequency (anything from 10 Hz to 500,000 Hz). CFAD page 15.
I'm hardly trashing Dr. Clark. Up to the point of discovering the effective battery wave, she was using frequencies, and did still use her frequency generator, but if she felt there was significant parasite infestations, she used her zapper with the all killing square positive offset wave.
