i found a web page some time ago with a list describing the different formulas, but i can't relocate. i'm interested in the dewormer, but i don't know what the difference between p/w and p/w/e, how much to take, how long, etc. since there isn't any description of the ingredients on the oldfashioned spices site. i'm starting to run in circles. could you post a link or describe this for me? thanks!
