allergic to psyllium-how do I cleanse/rid of plaque?

I am allergic to psyllium I found out after trying the p&b shakes. I have attempted to cleanse using just Bentonite clay but I get to feeling really bloated and have not had much success. I read many posts on Oxypowder and it doesn't sound like most of you think this expels mucoid plaque and I don't need a constipation remedy as this is not an issue for me. Many of you have writted of your success with Colonix or Holistic Horizons however these both contain psyllium. Does anyone have any info or ideas about a psyllium-less way of cleansing the MP. Thank you,
Lee
