Many of us can be extremely different then "the average", so it is impossible to say that one single way of cleansing bowel is any better then the other.
That is why there is no such a thing as "The Best" bowel cleanse.
Every person with experience in cleansing bowel have his/her idea of what "The Best" Bowel Cleanse could be. Every person is different, every person may need some variation - something that is just specific for him/her. Just like with diet.
THERE IS NO ONE SINGLE DIET THAT WILL ORK FOR EVERYONE!
You will have to find what way of cleansing is the best for you! Some people prefer enema, other prefer herbal cleansers, other prefere just better diet, or a lot of probiotics, or colonics, or any combination of those, ... some people hate enemas, some poeple hate herbal remedies, other are allergic to any yogurt culture, some people can not tolerate psyllium, or bentonite, or are allergic to herbs ....
Not every cleanse is good for every person. Prices for herbs are different, and recepies are differnt, and strength is different. We are different. You can not make simple comparations, and you can not generalize!
I just read on a website that 3percent hydrogen peroxide, and saltwater is the best and cheap. mix 13-30ml of 3percent hydrogen peroxide into a solution of 1 tablespoon of salt mixed into 1 litre of water. Drink this down within 10 minutes in the morning. after one hour introduce friendly bacteria such as those found in live yogurt cultures. Eat 1 or 2 cups of yogurt. You may need to do this as little as 3 days or as many as several weeks. I just tried it and drank about 8 oz. before i almost vomited. I am really bad when it comes to swallowing things. (smile) but with only the little bit I can feel the bowels moving.
Regarding cleanses, which one are you doing...
I can recommend Arise and Shine by Richard Anderson. I had done The Master Cleanse for 14 days with not much leaving my body but I felt good, then I did raw foods for about 5 days, then I started Arise and Shine and felt unbelievable...BUT...
no matter how good you feel while cleansing, whatever cleanse you do, it is SO VERY IMPORTANT to deal with underlying emotional issues, I cannot stress this enough.
Emotional issues need to be the addressed. And cleansing is the best time to do it because you are more open. So I say this again no matter how well you feel on your cleanse and you will feel emotionally and physically quite good, please investigate those issues you sense lie beneath the surface ...
I did a cleanse for 5 days: we fasted for 5 days and in the morning drank 2ltrs of salt water to induce a movement. Then we had a dose of a table spoon of Bentonite and psyllium husk at 9am and another at 1pm. We drank at least 5 ltrs of water a day.
It was miserable. I got extremely weak and depressed and my brain fog was overwhelming - I felt like I was underwater and I couldn't even put together a simple sentence. There was no way any emotional feelings could have been addressed since I couldn't feel or think about anything at all. There was no openness, no revelation, no release, no relief, nothing but sheer misery at a pre-verbal level. SOmeone on the cleanse told me that everyone was TRYING to stop thinking and 'how wonderful for you to have succeeded!'. Clearly, those people did not know what brain fog is or they wouldn't envy it.
Coming out of it, I am weaker. My brain fog is much worse and my bowel movements are still no more regular or full.
I'm already on a sugar-free-wheat -free-yeast-free diet and I always drink at least 4ltrs of water daily.
There isn't any 'mystical side' to colon cleansing as far as I can see. Or any real, life-changing health benefits either.
