Mode of Action:
1. Anti-inflammatory:
Glycyrrhizin, one of the primary active compounds in licorice, acts as an anti-inflammatory agent by inhibiting the enzyme 11Beta-hydroxysteroid dehydrogenase. This enzyme is responsible for converting active cortisol into its inactive form. By inhibiting this enzyme, glycyrrhizin increases the levels of cortisol, a natural anti-inflammatory hormone, in the body. This increased cortisol helps in reducing inflammation and has a protective effect on the stomach lining, potentially aiding in the treatment of digestive issues.
2. Anti-tussive:
Licorice is effective in relieving coughs by soothing the throat and reducing irritation. It inhibits the activity of the enzyme 11Beta-HSD, which normally converts inactive cortisone into active cortisol. By inhibiting this enzyme, licorice can increase cortisol levels, helping to calm throat irritation. Additionally, it acts as an expectorant, aiding in the loosening and expulsion of mucus from the respiratory tract. Its demulcent properties form a protective film over the mucous membrane in the throat, further alleviating cough symptoms.

- The root of Glycyrrhiza glabra is highly valued in traditional medicine, particularly in Unani medicine, where it has been used for centuries It is considered to have a hot and dry temperament and is known for its suppurative (promoting the discharge of pus), demulcent, and lenitive (soothing) properties.
