Licorice root is both an expectorant and demulcent, simultaneously soothing your airways while loosening and thinning mucous, easing congestion. It can also ease any inflammation that may be irritating your throat. Its main constituent, glycyrrhizin, is responsible for most of its effects. 30-50 times sweeter than sucrose (table sugar), it inhibits an enzyme 11beta-hydroxysteroid dehydrogenase (how would like you to write that on a name tag?) This enzyme regulates access of glucocorticoid (a steroid hormone) to steroid receptors, ultimately slowing the conversion of cortisol to cortisone. This increases the effect of cortisol and reducing inflammation. If you are on steroids, or have any problems with your kidneys, it is best to steer clear of licorice root.
Teas are a great way to get the benefits of sage all you need to do is steep one teaspoon of sage in a cup of water for about 10 minutes. You can also make a pretty awesome sore throat reliever by combining sage and thyme. Take an ounce of both grind them, and cover them with 16 ounces of apple cider vinegar. Be sure to shake it periodically and let it sit for ten days before using.
