Colon cleanse problem!

Yes,
I got some powdered herbs you mix with water because I have been diagnosed with acid reflux and don't seem to digest things well. My problem is one of the ingredients is cayenne pepper and it burns so bad going down my esphogus. I don't mind it really but Will it hurt my esophagus? The ingredients is Aloe, senna, cascara sagrada, ginger, barberry bk, garlic and cayenne in that order. Any advice would be great since I have heard you should cleanse the colon and then try to get rid of parasites next if you have digestive problems.Thanks
