Much of the negative propagnda against CE's was perpetrated by a single person on curezone. The same person who launched a campaign against liver flushes.
Aside from Telman's excellent post, there are also some common sense factors to consider.
1. Many, many, many great natural healers have employed coffee enemas as part of their arsenal, with excellent results. Keep in mind that the person who has turned people off of CE's perhaps deals with people in the tens and perhaps low hundreds (being very generous). Dr. Gerson, in contrast, was dealing with people in the many thousands. The same applies to Dr. Schulze and Dr. Christopher. Different league. One is bush is league the others are major league.
2. People who are intolerant of caffeine have liver clearance issues. coffee enemas clear stones and waste from the liver addressing the problem of clearance.
3. Have you ever actually done a Coffee Enema? It is one thing to read about the potential negative effects of a certain therapy, and another to experience it and possibly reap the benefits.
4. coffee enemas increase the enzyme Glutathione Peroxidase, one of the major detoxifying liver enzymes. Oral ingestion does not have this effect.
intolerance to caffeine, which also suggests he has liver clearance issues, which is beyond ironic since he spends half of his curezone time denigrating liver flushes. As has been pointed out to him many times, the bitters which he recommends are not always effective, and it is necessary to do flushes or CE's in the beginning to clear out the major garbage before the body can reset itself and then use bitters as a maintenance program. Very few people who have been chronically ill for a long time resolve the problem with bitters. Conversely, many people have resolved their problems with CE's or liver flushes.
True health is being able to eat junk food or have some caffeine without experiencing too many problems. Obviously, in order to get to this state you want to do everything in your power like abstaining from said substances. Caveat Emptor though with people who are advising you that still have problems themselves with hypersensitivity.
