If you have Schulze's IF#2 the bottle label shows the ingredients, so this will confirm for you if it contains peppers.
I am away from home at the moment but I do have a somewhat old jar of Schulze IF#2 right here in my hands.... the jar was bought probably 4 or 5 years ago if not more. The listed ingredients are: Psyllium seed, Apple Pectin, Activated Willow Charcoal, Marshmallow root, Bentonite Clay (Pharm grade), Slippery Elm bark, Peppermint leaf and Cayenne pepper blend.
