Caveat: if you have chronic bloating, you should see a doctor. This research is more informative than diagnostic (as you should be aware).
Interesting, seemingly well-supported herbs for different issues. Many of the symptoms are similar or overlap, which is why this research is interesting to me–if one herb can target a couple issues, it might be cost-effective when muddling through diagnoses.
Small-intestinal bacteria overgrowth: when your normally ‘clean’ small intestine has bacteria. Treatments include: peppermint oil. **note, this is enteric-coated peppermint oil so it dissolves in the small intestine, not the stomach. Regular peppermint oil drops will probably be less effective.
Irritable Bowel Syndrome: aka the doctors don’t know what’s wrong with you. Treatments include: peppermint oil (different proof, same use of ECPO).
Overgrowth of yeast in your intestines, which may concurrently present itself with topical yeast infections. Treatments include: Black Cumin seed oil. See also here. Research suggested it was most effective as an oil when extracted with methanol, but I can’t find a brand which definitively does so.
For topical yeast infections, tea tree is pretty effective, but because it is toxic when ingested internally, I would not be taking these drops internally. See here.
I will make a post on IBS and working through it with diet, but keep in mind Candida & and SIBO can be conclusively diagnosed, whereas IBS is essentially an umbrella term.
