Oil of Oregano is now my "go-to" cure when I start to have a Diverticulitis attack. Recently I had another severe flare-up. Called my doctor and he called in Cipro and Flagyl, but I held off taking them while I tried to cure the attack with Oil of Oregano. It worked. I did not have to take the antibiotics. I took it several times a day for a few weeks, and I am now pain-free.
