I'm absolutely no expert here, but I do know what I learned after my aunt's episode.
She, of course, did antibiotics at the time, but realized that she needs to address the problem before it becomes a problem that needs antibiotics again. I sent her info on liver flushes so that she can address that when the diverticulitis is no longer her main issue.
So, she is avoiding nuts and talking to health food store people and I send her what I can.
I found 180,000 HU cayenne pepper and sent her that and a tiny funnel.
I also sent her the "Lemonade drink" recipe that has some cayenne in it.
And some information about aloe vera.
I read somewhere that it might not be a good idea to do enemas because the pockets that are infected may be eaten nearly thru and the pressure could damage them further.
Anyway, high heat cayenne pepper can supposedly heal the wounded areas along with the aloe vera, so I think her plan is to drink the lemonade drink and take some extra cayenne pepper in gelatin caps and drink aloe vera everyday.
I also sent her the recipe for P&B shakes to get the 'debris' out of the way. And she knows about my removal of parasites, so she'll probably get some parasite medicine.
I'd be careful here if you think you have this (or have been diagnosed). Fever and pain indicate infection and you might want to have a doctor handy in case you have a problem - people sometimes die from diverticulitis.
I've been doing a lot of P&B shakes lately and for awhile my poo looked exactly like the 'divers' I read about on this site somewhere. I'm on a campaign NOT to get colon cancer like my great grandmother OR diverticulitis like my aunt. After a couple of weeks of seeing non-stop parasites, rubbery poo, and 'divers', I'm making 12-18" long BM's, no joke. I may have cleared all 'blockages' but will continue to drink them for another week just to be sure and then maybe drink them periodically.
I think there is a forum for diverticulitis somewhere, just starting reading all the back postings you can find, plus type in the word in google on here and search for postings.
Hope this helps - I'm sure there are a lot of other folks on here much more qualified to address this.
