I'm sorry you feel jipped. But, just because Healingwell doesn't personally recommend the company or its products doens't mean that it's not legitimate. Healingwell just sells ad space to Google, who puts up targeted links that people pay good money to have listed. Have to have the ad money so we can have this place for free.
I would suggest you call your dr.'s office and see if s/he has any problem with you trying this product. If not, then take it as directed. If you start pooping, then it's working. If you feel bad or hurt, then stop taking it.
I have heard that some colon cleanse companies claim that you know their product is getting out "built up" junk when you start pooping out black stringy bits. I don't buy into this since I had my colon perfectly emptied by the colonoscopy prep (I have pictures to prove it!) and I never pooped black. I think this is just the colon cleanse pills that you are taking that's turning your poop black (Pepto Bismol will also turn your stools black as a side affect--doesn't mean anything). But, the whole point is to get a laxative effect and poop your colon empty, and if it does that, well then, it's done what you paid money for it to do and it doesn't really make one difference or another if you pooped black, brown, yellow or purple.
I really don't see the need for this sort of thing other than for people who are constipated and who want to try and get backed up stuff out, but some people use it as part of a ritual/religious purification or do it before a fast and swear by it. It's not really a cure for anything in particular, just a way to flush out your system. If pooping yourself empty for the next 24 hours makes you feel better, then by all means, go for it. If I ever want to flush myself out, though, I'll just eat a whole pizza and drink a 2 liter coke. That'll give me the runs guaranteed!
