Cleansing is usually a slower, more gentle way to go. Flushing produces rapid results. There are times when both are needed, other times just one procedure can produce the desired results in the way most suited to an individual. If you do not have acute symptoms of liver/gallbladder trouble, then a cleanse would be a good gentle way to go. I would suggest that you spend some time researching the ingredients in the commercial cleanse you are considering. There are a lot of worthless products out there, take that from someone who has been ripped off more than once with health promises that were never fulfilled.
