From my personal research, jarred silver skin onions in WHITE vinegar!
I never turn to medicines, i only turn to onions to cure my sickness!
I believe this cures the sickness by...
The onions trapping the vinegar in between the layers. Once digested the onions release the vinegar into the stomach. The vinegar then mixes with the stomach acids causing the acids to stop churning, to keep the stomach acids at bay.
