Clarkia vs Dr Clark Research Assoc

I noticed that at the http://www.drclark.com site, they sell the parasite cleanse as (3) separate ingredients (Blk Walnut Tincture, Clove capsules and Wormwood capsules).

Then at the http://www.sbherbalremedies.com site, they sell Clarkia with all 3 ingredients in one tincture.

Is there a difference in effectiveness?

Are the websites related or 2 difference businesses? Which one is associate
with Dr Clark?

Thanks.
