There are 3 basic types of internal cleansing:
Internal cleansing is far more important to your health than bathing!
There are many different cleanses for each type. I recommend the following 2 books as a good starting place. They will both help you to begin to understand the importance of internal cleansing. The first book which I highly recommend is:
A CURE FOR ALL DISEASE by Dr. Hulda Clark
It's important that you follow Dr. Hulda Clark's suggested protocol carefully for the sequence in which the cleansing should take place. In many cases, when cleanses are done in the wrong sequence you can have an undesirable healing crisis and become very sick. I followed Dr. Hulda Clark's protocal of sequences with great results. More than 2,000 liver and gall stones were expelled when I did her liver cleanse! When you've visibly see the massive amount of stones and parasites that are released from your body after undergoing the various cleanses, there can be no questions that this will improve your health and the efficiency of your organs. After I completed her series of cleanses in their proper order, I was able to complete a variety of other types of cleanses with positive results.
Another book that I recommend from personal experience is:
MASTER CLEANSE by Stanley Burroughs
I have been recommending this book -- actually it's more like a 50 page pamphlet -- for a number of years now, and I've seen many miraculous health improvements in all who followed it. This a is very inexpensive way to start your cleansing process, and one of the easiest and cheapest that I have done.
