Another remedy is anise tea. You make it by brewing anise seed. It is given to babies with colic in many parts of the world.
An old-fashioned remedy for an upset stomach is to simmer a couple of bay leaves and add a pinch of sugar. Take by the teaspoon as hot as possible.
A tiny bit of baking soda in water helps with an upset stomach ...You would have to google to see what the ratio of baking soda to water is. I think its something like a quarter of a teaspoon to an 8 ounce glass of water, but I'm not sure, so its best to check it out for yourself.
Or maybe Paxiled could answer that for you?
Pepto Bismal contains the toxic and bactricidal substance Bismuth. It is not a simple "antacid".
Chances are it will work it's way out of your system.
The other problem with antacids are that, though they can work for some immediate relief, the stomach needs acid to digest protein, and so antacids can have a rebound effect where the stomach produces more acid to compensate for the reduction. On the other hand, this also could have just been your digestive system getting rid of whatever was bothering it in the first place.
Indigestion is generally thought to be due to too much acid. However the cause is often too little acid, so, when an antacid is taken for relief, it makes the condition worse. The next time you have an upset stomach try taking one tablespoon of apple cider vinegar.
Nausea is common when lack of acid slows or halts digestion.
