How do they differ and how do they complement?
Why do we like both?
The focus of Dr. Clark’s work has been on the relationship of parasites to disease as well as toxins contributing at every point.
Dr. Kelley’s work focuses on using enzymes to digest disease and rebuild.
At first look they seem at odds, however in Dr. Clark's first book she mentioned using enzymes to eliminate parasites.
We like to use both because using Dr. Clark’s Zapper and Black Walnut is a low cost way to get the parasites out and Dr. Kelley's enzymes to digest the diseased tissue and help rebuild the body.
The list of overlapping recommendations is extensive.
