How to kill bacterias in the small intestine?

It seems that the problem with sibo is bacterias that are in the small intestine and should not be there.

So eradicating them could be a solution.

I found garlic and ginger a bit harsh.

Curcuma seems less harsh but I 'm wondering if it would be enought.

peppermint oil and Grapefruit-Seed-Extract seem to be not that safe as I have been told here.


What othets thing could cleanse the small intestine.

Any help please ?
