From the perspective of Hulda Clark 's protocol[s], zapping is just one of several procedures that can be done to reduce and or rid parasites. Other procedures involve the use of Black-Walnut Hall Tincture, as well as supplements such as Clove and Wormwood . The latter three do affect and penetrate/travel the deeper reaches of the body - the gut/stomach/intestines/colon. Using all of these in combination, including zapping, constitute a multi-pronged approach, a more thorough method of ridding parasites. Clark especially advises using all of these in conjunction with other procedures and other supplements in preparation for a successful liver flush.
