...In a lecture in San Jose California on 26 Sep 98, Dr. Richard Anderson told the story of one of his patients who underwent the cleanse in Hawaii a few years ago. The patient was passing long strands of the rubbery mucoid plaque, some over 20 feet in length! Fascinated, the patient hung the strands over his clothesline in the back yard. He then took a length of the plaque, and packaged it in a box to send to the mainland to prove what happened to him. He mailed the package at the local post office in Hawaii.

A few days later, two serious-looking officials in ATF windbreakers knocked on the patient's door and asked him if he had sent such and such a package to such and such an address. The patient said yes, and asked what was the problem. They answered that the post office has dogs that sniff out all packages mailed off the island, and that one of them had become very excited about this package. The patient asked what were the dogs trained to detect. Only two things, came the answer: drugs and explosives. Which dog was it? The one for explosives. The patient was incredulous, especially when he recalled that he had worked with munitions some 25 years ago, and his job was to handle explosives! He explained the detox cleanse to the two agents and they were satisfied. This story illustrates the power of a such an intestinal cleanse: the body had retained these strong toxins in the mucoid plaque lining of the colon, stored in a concentration powerful enough to be detected by dogs through the layers of wrapping of a sealed package some 25 years later!
