Alternative treatment for colon?

For some time I have bowel problems. I still have a colonoscopy. If I come to find something, I do not take medicine and / or treatment. I treat with alternative medicine. I’ve been taking many pills. I have heard that fiber is good as pysilum not know what else I have to take to clean my gut of a few. No Porrassa and sellers of products. What I can take besides aloe? Has anyone tried colloidal silver or some alternative treatment.I have absortion’s and digestin problems.
