I use grapefruit seed extract only when I have a diverticulitis attack and I find it to be effective. However, researchers have found benzethonium chloride or triclosan in many samples of liquid and powdered grapefruit seed extracts so I would not use it except as necessary. I take 4 oz. of raw milk kefir each day (2 oz. In the morning 1/2-hour before breakfast and 2 oz. before going to bed). I have started using organic UNREFINED coconut oil in my cooking (no coconut taste) and I even spread it on my toast - delicious and still no real coconut taste. During my first attack a few years ago, the medicine was making me very ill so I researched on the internet to see if their was someway I could heal without those terrible meds.
I came upon a site called greattastenopain.com. It is all about how you combine your food. I can eat ANYTHING I want (well, almost anything) as long as I combine it the way the site tells me to combine it. I wish I could say that I stick to it all the time, but I don't. However, if I start to have pain, it will stop almost immediately if I go to that way of eating. There is a four-day free diet on the site and sometimes that is all you need. However, I have purchased her materials and found that they are worth every penny - not that expensive either.
