Garlic contains a powerful compound called allicin, that has antiseptic properties, thus exhibiting antibiotic traits. It is also very efficient at boosting and modulating your immune system which is what interests us when talking allergies. Not to mention it’s anti-inflammatory characteristic, which will sooth any ongoing symptoms. Garlic is pretty amazing and just like the compounds above, it can be supplemented with or taken in natural form. If you want to go for the former, just buy a good quality capsulated extract and follow the instructions on the label. If you want to go for the latter, take one clove of fresh garlic and cut out two thin slices. Place them on the inside of each cheek and suck on them like a cough pill. The aftertaste won’t be the greatest but it sure is effective.
