 One is called Atrantil. We did a whole show on it. It's a South American herb that can be helpful for killing the methane-producing bacteria that proliferate in that. Also, I like high-dose garlic, a product that I like to use is something called Allicin. We do like Coyolic-aged garlic extract, but that has a lot of other benefits. But for GI purposes, I might recommend a high-Allicin product.
