I bought Dr. Clark's newest book on HIV/AIDS. In that book she improved her cleaning foods techniques. She suggests using Lugol'sIodine now instead of HCL. But best of all, she is using her zapper connected to a box that you put your pre washed friuts and vegetables on. You also put non washable food on this box to sterilize them too.
She also has a zappicator unit which is different than the regular zapper in that it produces a different frequency targeted for molds, fungus, parasites and their eggs. I love this unit.
Unfortunately, they are discounting making this unit. But in her new book she gives the instructions on how to make them.
