Garlic is helpful to people who have asthma! It has a bronchodilator effect, which means that it helps reduce muscle constriction around ones airways. This makes breathing easier. It can be eaten with your meals or even taken as supplements. Others think it combats inflammation that leads to swelling of the airways, thus preventing asthma incidences. Consuming garlic can do a lot of good but definitely does not replace your doctors recommended medicine. Note that it is always safe to seek your physician’s advice before using any new product or drug on your skin.
