Boosts immune system
Licorice also appears to enhance immunity by boosting levels of interferon, a key immune system chemical that fights off attacking viruses. It also contains powerful antioxidants as well as certain phytoestrogens that can perform some of the functions of the body's natural estrogens; very helpful during the menopause. Glycyrrhizinic acid also seems to stop the growth of many bacteria and of viruses such as influenza A.
Relieves pain and stress
It has an aspirin-like action and is helpful in relieving fevers and soothing pain such as headaches. Its anti-allergenic effect is very useful for hay fever, allergic rhinitis, conjunctivitis and bronchial asthma. Possibly by its action on the adrenal glands, licorice has the ability to improve resistance to stress. It should be thought of during times of both physical and emotional stress, after surgery or during convalescence, or when feeling tired and run down.
Control respiratory problems and sore throat
Licorice eases congestion and coughing by helping to loosen and thin mucus in airways; this makes a cough more "productive," bringing up phlegm and other mucus bits. Licorice also helps to relax bronchial spasms. The herb also soothes soreness in the throat and fights viruses that cause respiratory illnesses and an overproduction of mucus, such as irritating coughs, asthma and chest infections.
