I would not recommend that anyone actually ingest this product. I have two reasons for saying so:
1. Colon cleansing products are nothing but snake oil, at best. A normal colon doesn't contain any "impacted feces" or "undigested material". If it did, you would have obvious symptoms of severe illness. Promoting such a product as a "toxin purge" is just BS at its finest.
2. Some of these products are actively dangerous. Oxy-Powder includes among its ingredients the substance "ozonated magnesium oxides". The Material Safety Data Sheet for
magnesium oxide is interesting, as it includes the remark that this substance, when ingested, causes GI upset and is cause to seek medical attention. Granted, the dose involved may be much less in Oxy-Powder than that considered toxic.
"Ozonated" implies that the products is infused with a high oxygen content, and that the stuff has strong oxygenating properties. Ozone is used in industrial settings to sterilize clothes and equipment, and is used in some hospitals to disinfect an area.
You don't want to kill all the bacteria in your colon. A healthy colon has an active bacterial colony of "good" bacteria that is part of the digestive system. The bacteria manufacture some of the nutrients the body needs. You can improve the good bacteria content if needed by eating yogurt with live bacteria cultures.
Frankly this product sounds harmful to me.
Basically it sounds like this stuff makes you crap violently. Oxy-Powder may be useful as a laxative, but there are plenty of proven products on the market for that.
