Hi,
It's an oxygen cleanse whch liquifies the waste being stored in your ntestines (we all have it in there UUUUUUGHHHH!) The cleanse lasts 7 days and then you just take a couple capsules every other day for maintenance. I chose to do my cleanse with oxy powder. I tried taking tons of psyllium (which did not work well enough for me) before I discovered the cleanse. Hope that helps.
