Hello & welcome to the forum. Here in the states the gi's will put a patient on Remicade to heal fistulas. It has a pretty good track record with healing them & keeping the disease in check. The 5 ASA's are typically used for UC instead of crohns. If your disease is not under control, I doubt you will have a lot of success with CBD oil. I do not know where you are reading & getting your information from. Keep in mind, just because you read it on the internet, it does not mean it is accurate or true.
You can always ask your dr & get his input.
