They are just cheap green olives stuffed with the red pimentos and in brine - not in oil, although I'm sure it works either way. The pimento looks to be just a red jelly really, and I don't think that is important either.
Give it a try, can't hurt right :)
I think this wouldn't help those cases that are caused by worms. Mine seems to be due to some kind of dysbiosis / SIBO.
