It seems like you are trying a lot of natural products.
I know this is very controversial, but when I was desperate for relief, I tried the vitamin E enemas and they did seem to help, at least reducing the mucous and pain. It is not something you would want to be your only treatment. Probiotics and Aloe Very are very helpful when flaring.
When flaring I needed to watch my diet. My problem was with most fruit and raw & gassy vegetables. Activia yogurt helped, too.
