Beta blockers are prescribed to treat heart problems, anxiety such as "performance anxiety" or stage fright, and high blood pressure. They work by blocking adrenalin, but they must not be prescribed to people who suffer from asthma and specific heart or arterial conditions; a doctor’s advice must always be sought first.
There are many foods that can act as natural beta blockers. To feel the benefits, it is important to consume these foods as part of a balanced diet.
