And, no--Dr. Clark NEVER said the herbs alone would do it. She ONLY added the herbs because she found sometimes the zapper couldn't reach inside the intestines. The zapper was her main parasite killing modality, period.
I've used the SCADA RSG-4 quite successfully for years. It runs about 150$ or you can make one yourself--Dr. Clark explains several.
I know nothing about all the hyped versions or mud slinging idiocy that goes on now--at the pharmaceutical cartel's orders, I'm sure--if you can't keep them away from zappers make it so damn confusing they can't figure out which to buy.
