Andrews Salts are a remedy for indigestion, working as an antacid and a laxative.
Constipation is a common cause of trapped wind — if your bowel is fuller than usual it can keep you from passing gas as you usually would causing buildup.
In helping to clear your constipation Andrews Salts can help to relieve your trapped wind too.
By working as an antacid, this product also helps to relieve indigestion or an upset stomach, which are both common causes of bloating.
