Psyllium expands/swells, this action stops the action of the intestines and eventually reuins the muscles, it has no use in the herbal world of repairing the small and large intestines. The same with the enema, good as an emergency, but just ask those that destroyed their muscles and must take an enema morning and night for the rest of their lives, a good example, the Mexican Coffee enema. I know people that went to Mexico, only to have a quack MD that killed too many in the states subject them to coffee enemas and come home addicted for life.
Dr. John R. Christopher perfected an eighteen hundred's formula from Germany. Dr. Christopher changed thias formula many times over his life and it is one of the best herbal formuals of all time. Sadly the FDA doesn't like all the ingredients today and you may not find the original formula sold commercially. on the other hand, it is still being made for private use by people who accept the use of herbs as experimental. This is the only herbal formula I reccomend. If you ever ask for my free 108 page book by mail, ask for a free newsletter Dr. Christopher wrote about this formula and colon health, I don't normally copy it unless someone is seaching to rstore the colon with the use of herbs.
Oregano oil and Olive Leaf are 2 of the KINGS in the herbal world, don't mess with oregano oil unless you have read about it and are prepared to use it, it can burn like super hot cayeene peppers.
