Onions and garlic belong to the same family of plants, hence they both contain allicin. Onions are also beneficial for the immune system due to an additional compound called quercetin, a nutrient that breaks up mucus in the head and chest. If you suffer from allergies or circulation problems, or are prone to flu, onions are recommended, as they produce a strong immune effect, protecting your body from such conditions.
