Loiman,
There are different substances you can use for the parasite cleanse. I used something called ParaCleanse I think. I'd have to look. Basically it was wallnut shell and something else. But I only took it intermitently, so I would say I did the liver cleanse without fully doing a parasite cleanse. I had no problems. It went very smooth and got out hundreds of stones of varying sizes. Biggest about 1/2 inch in dia. I am doing my second cleanse tonight. I will post the results tomorrow.
So, Go for it!
