Licorice is used for various digestive system complaints including stomach ulcers, heartburn, colic, and ongoing inflammation of the lining of the stomach (chronic gastritis). Some people use Licorice for sore throat, bronchitis, cough, and infections caused by bacteria or viruses. May be helpful for laryngitis.
Caution: People who regularly take large amounts of licorice -- more than 20 g/day -- may raise blood levels of the hormone aldosterone, which can cause serious side effects, including headache, high blood pressure, and heart problems. For people who already have high blood pressure or heart or kidney disease, as little as 5 g/day can cause these side effects.
