Colon cleanse?!

Colon cleanse?

i always hear about people doing some type of colon clease and they say how beneficial it is and helps one feel better and is good-but why dont drs recommend this if it is such a good thing? and what are the benefits of it supposed to be-can they be dangerous or cause problems? any info?

I do not like anything up my butt and that is why I drink water to cleanse me internally. Also for optimum health, I take 2 tbls. apple cider vinegar before a meal. ACV has 93 vitamins and minerals. Hair and nails become long and strong. 6-8 glasses of water per day is what is needed here.
