The effects of honeysuckle and licorice in water can be adjusted mainly to treat diseases related to upper respiratory tract infections, such as cough, coughing phlegm, sore throat, fever on the body, and mouth ulcers. Because honeysuckle and licorice have the effect of clearing heat from the surface, they can also moisten the throat and stop coughing. In clinical practice honeysuckle and licorice can be used in combination to provide adjunctive treatment for inflammatory diseases of the digestive tract, such as Crohn’s disease, gastric ulcers, enteritis, and especially for gastritis, which is very effective in inhibiting the growth of Helicobacter pylori and has a restorative effect on ulcerative gastritis. In clinical practice, honeysuckle and licorice are not particularly cold, so they are ideal for long-term oral administration, and are useful for improving the treatment of viral and bacterial infections.
