If you have trouble with the pyloric sphincter leading from your stomach into your duodenum, allowing stomach acid to get in there, it may not be a good idea to take the tincture at this time.
Another idea is to try just a TINY amount. You could even try some of those ingredients individually. Can you tolerate drinking a little raw ACV?
If your problem is some kind of bad parasitic overgrowth, it would actually help.
I used to have that pain (several years ago). Eventually, with diet changes, sleep, and time, all of that healed. When I have a putrid feeling in my stomach more recently, though, raw ACV helps (I didn't know about raw ACV back then). I probably have something growing that shouldn't - I get it when I eat a little too much of something sugary (like dark chocolate). Killing my stomach acid with antacids only made my problems worse.
