I was even a constipated child ... I tried the oxygen cleanser Homozon, the grandaddy of oxygen cleansers. It did work as long as I took it. It did nothing for healing my proplems, it relieved a symptom, so was like a Rx for me. I've switched to Lower Bowel Balance by the guy at the Ask Barefoot forum here. For the first time in my life, I feel peristolic action in my bowels.
The guy at Ask Barefoot also makes a kit that follows pretty much the Hulda Clark protocol for liver flushing, minus the tastes that folks complain about.
Another thought:
NEVER try to flush when you're constipated. You're lucky you threw it up.
