Just for overall health and from the book Cures for All Cancers (not saying this is your cure), might be useful to a optimal performing system in ones own body. Amazing what comes out of your system, see links to photos within this:

Also Dr. Clark has other useful ideas and contraptions that are interesting to know about, if you have interest in looking. After reading this know the the zap mentioned(which is useful in riding of parasites within your body) or 'zapper' is talking about the Hulda Clark zapper unit....very interesting contraption, simple, no patents, many people worldwide have used it for years, with results and claims. It sounds ridiculous that such a device is useful, but with thousands of people as witnesses on the plus side, it appears it is not junk and a couple other Drs. have their version of it with similar testimonals, can even be bought on ebay if you search Hulda Clark zapper or Clark zapper and then read about it.
My brother did the liver, kidney flushes and has improvement in blood pressure and other things and had wonderful things that came out from doing this. Cost is little to nothing, the results might be priceless to someone and you don't need an expensive doc and drugs. It is amazing how much junk is in our systems and what it can all do to influence all kinds of things.
