The colon is the most obvious channel that deals with getting rid of toxins from the body. I'm glad you wrote, because colon cleansing is a very important and healthful thing to do, and unfortunately most people don't think about their colons until there's some sort of miserable symptom happening.

When the colon functions properly, toxins and waste are absorbed in the digestive tract and then removed via bowel movements before they can build up and cause harm. Just like you change the oil in your car regularly to protect your engine from getting all gummed up, it's a great idea to clean your colon too! And it's very safe, and not at all scary, by the way. 

For example, Renew Life offers a product called Bowel Cleanse. Bowel Cleanse is a powerfully effective natural laxative gently blended with 100% organic fiber and bowel-stimulating herbs formulated to help cleanse the colon and promote healthy bowel function. Brenda Watson designed these products so that you can manage your cleansing program while you continue with your normal life.

Another form of bowel cleansing is colon hydrotherapy. This is offered by a practitioner called a colon hydrotherapist. This gentle process allows you to even more completely cleanse and detoxify your bowel. You can learn about it here – http://www.brendawatson.com/media-room/.
