The only product I've tried is Parastroy. I chose it because its in capsules and does not contain alcohol. Others believe getting the medicine in tincture form is better. I've had good luck with Parastroy, and have passed quite a few parasites, mostly roundworms, and Tapeworm segments. I go off this round Monday for nine days. During that time I plan on taking the CoQ10 dose Dr. Clark suggested. After nine days I will be taking a product called Paradex that I got from my doctor. He has guided me through this cleanse.
I bought my Parastroy on line at LAVitamins.com, the place I order most of my cleansing supplies. I believe that Parastroy can also be purchased at GNC and other health stores.

I too tried Clarkia and saw nothing. I'm just hoping that means I don't have any visable worms. I am now taking ParaGone which I really like. I still haven't seen worms but my BM's have changed a lot. They are really dark, lots of plaque and mucous and floating yellow specks which I think are Candida. I am using ParaGone mostly for Candida since it is good for this too. Plus I just started Threelac today. My personal opinion is I like ParaGone much better than Clarkia . I am also using CandiZyme to help digest the Candida. You can use this or ParaZyme which helps your body digest/assimilate what you are eliminating. RenewLife is the company that makes ParaGone, CandiZyme and ParaZyme. The link is below.

Didn't see part of your question responded to, so thought I'd chip in. Dr. Schulze 's #1 and 2? I expect you are talking about his IF #1 and IF #2. These are intestinal formulas to clean the bowel. They are for a different purpose than a parasite cleanse. My apologies if you are speaking of some other #1 and 2.

I think you want to use IF #1 before and maybe during parasite cleansing, to be sure your bowels are moving and can get the critters out. Then IF #2 is to follow to clean out some mucoid plaque, which can also harbor parasites.

I love this IF #1 and usually take one pill a night.

Best health to you, and good luck cleansing!
