What began as a simple German folk remedy has now been proven as a scientifically effective method for fighting off bloating. In research conducted at Stanford University it was found that sipping two cups of chamomile tea daily could help ease bloating and belly pain within just 24 hours. This is because chamomile calms the adrenals and the production of a stress hormone called cortisol that can interfere with digestion and produces painful gas and belly spasms. Not only does chamomile tea soothe the stomach, it also causes the brain to produce more enkephalins, or painkilling hormones that will help fight off depression and negative thoughts.
