Most of us do some preparations - parasite programs, kidney cleanses and or softening of hard stones, liver support - and then until we know how our bodies react we follow the instructions as closely as possible. I had what seemed to be fibromalagia and following Clark's programs, doing Epsom Salts sweat baths, taking detox suppplements and herbs, was helpful. I also had Lyme Disease and treatment with homeopathic drops and Clark's Zapper was effective. Also I had undiagnosed Celiac Disease and the strict gluten free diet was effective.

for symptoms and tests.
