I completely agree with these sentiments. My wife tried one of these pseudo science cleanses and she ended up the hospital as a result with severe bowel problems.
We do not need to cleanse our bodies as they do it on a daily basis already. If we do need assistance with cleansing, then we have serious health issues and should be under a Doctors care. Take care of your self and stay away from crackpot health cures for nonexistent ills.
