You can try oil pulling, too. I feel like that helps my digestion. I haven't been using the right kind of oils, though. Just extra virgin olive oil and a few other random oils.
They say to use sesame oil or expeller pressed sunflower seed oil. One perk for extra virgin olive oil, though, is that it really helps with singing! I don't suppose the other oils are like that so much (could be wrong).
Anyway, oil pulling (AKA oil swishing) is where you swish a tablespoonful of oil around in your mouth for about 20 minutes (one or two times a day), spit it out (not in the sink; I spit it outside) and wipe your mouth out.
