All in know is that my dog had this huge tumor on his neck. I could not afford to have it seen about. I read up on tumors & after a month of one capsule of Pau D'Arco a day that tumor shrunk & disappeared & never came back.
If it cures a tumor I think it would help heal crohns. It has many uses.
Every one is different, so use your discretion.
