Inserting Aloe Vera and Lglutamine into rectum?

For proctitis or rectal inflammation, has anyone tried (or heard of anyone who has tried), using an application to insert narutal healing substances, such as Aloe Vera gel, L-glutamine or others), to naturally heal the inflammation? How were the results? I have very stubborn rectal inflammation that has only partially responded to medications so trying to think of other solutions to complement the medications I am taking.
