A low frequency zapper would work best for penetrating the intestines. Drinking ozonated water works well for intestinal problems.

note that general zapping for such a serious condition is irresponsible, and not at all what Dr's Clark, Loyd, and Sutherland suggest for these frequency treatments and bioelectronic medicine.

In addition to syncrometer testing, there is (which I use) the Fscan for using an imprinter (plate) with the tissues (intestinal, stomach, etc.) samples on the microscopic slides to direct the scan (and or treatment too) through the tissues specific to what you are wanting to test (or treat) the presence of virus, bacteria, and parasites for (those that are causing your ulcerative colitis).

Also use http://www.frequencyresearch.org for questions on PHOTOANALYSIS and the energetic testing which Dr. Jeffery Sutherland is using to pinpoint EXACT frequencies involved in such conditions, like cancer, LYME's DISEASE (a bioweapon) and so on. Also VERY effective and a GREAT ADJUNCT and EQUALLY IMPORTANT test is the RADIONICS SALIVA TEST by Dr. Richard Loyd at http://www.aboutroyalrife.com and http://www.royalrife.com SEE "A CURE FOR ALL DISEASES" searchable on that site, and pages 561-571 and the CAFL for finding out the SPECIFIC FREQUENCIES you need to use with PLATE ZAPPING to KILL the parasites or pathogens INVOLVED... otherwise, by only using a general one frequency zapper, you are pissing in the wind, and on a fire that can consume and kill you. Trust me, I have the recent tests and 2 years of experience of daily "zapping" and frequency therapy to prove this. GET TESTING, and get your plate zapping equipment or build it, and GET SPECIFIC FREQUENCIES like the Dr's suggest... and direct those RIGHT INTO the INSTESTINE and STOMACH tissues or whatever organ tissues are involved in your illness and BE SERIOUS about your research treatment. Don't general zap or "shoot in the dark" TEST GET TESTING and get specific and SNIPE them out, and FOCUS that energy DIRECTLY the the target tissue involved.
