Drinking a good amount of water is one of the most basic natural remedies for heartburn you can think of. It washes away the acid burning and balances the acidity out
To prevent heartburn or acid reflux you can drink at least 4 pints (+/- 2 liter) of water spread over the day.
Eating an apple, or sometimes even just a part of it, can really relieve your heartburn. It works basically the same as the vinegar part, where the good acids help you stop the heartburn
It varies again from individual to individual to which variety works best for you, experiment a bit.
