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.
