Heartburn or acid reflux is a symptom of GERD (acronym for gastroesophageal reflux disease). Typical treatment may include medication and possibly surgery. Definitely, changes in diet would be part of the protocol.
However, Western medication often includes side effects and there is a danger of overmedicating. Why not try a simple home remedy instead that has additional health benefits and little or no side effects other than to remove the heartburn and prevent it from coming back? Very easy to procure, a very inexpensive remedy that works immediately.
