Since ancient times, it has also been used as an expectorant, particularly in Ayurvedic Medicine. Modern cough syrups frequently use licorice extracts, proving once more some of the wisdom of the lore of old. Conventional and naturopathic treatments of mouth and peptic ulcers sometimes also utilize Licorice, and it may be used as a topical agent for treating shingles and, as some herbalists claim, oral or genital herpes. Licorice has also been found to be of use in treating digestive ailments such as leaky gut syndrome, irritable bowel syndrome, constipation, and Crohn's Disease. Note: Use should be avoided if you are pregnant, nursing, or have high blood pressure.
