Original Herb:

Glycyrrhizae uralensis Fisch (licorice root)

Chemical Composition

GL consists of triterpenes glycyrrhizin and glycyrrhetinic acid, usually as salts of glycyrrhizic acid and ammonia, calcium, potassium, iron, or barium. The glycyrrhizin capsule we use is a potassium salt of glycyrrhizic acid.

Traditional Use:

Licorice is the most frequently used herb in Traditional Chinese Medicine (TCM) and has been extensively studied. TCM classifies licorice as a sweet, mild herb and uses it to supplement the body, clear "latent heat," regulate stomach functions, expectorate the lungs, and invigorate the spleen. It has been used as an antipyretic, detoxicant, and anti-inflammatory. Many TCM formulas use licorice as a corrective adjutant and harmonizing ingredient. Clinically, it is used for cough, palpitation, stomachache, peptic ulcer, phyogenic infection, and skin rashes.

Pharmacology:

     Anti-viral effects: GL induces the generation of interferon-gamma in test animals and in humans. It can prolong the survival of mice following injection with hepatitis virus MHV. In rabbits, it can inhibit virus proliferation. Seventeen hospitals in China have studied the therapeutic effects of GL on 300 cases of hepatitis B. The clinical curative rate was 44% and the effectiveness rate was 77%, with 41% of the patients seeing their HBeAg serum positive status convert to negative. Treating viral hepatitis with GL can significantly shorten the disease course, accelerate recovery of liver function, normalize ALT and AST, and turn HBeAg to negative in about 40% of patients. Studies in Japan have confirmed these effects.

     Protecting and healing liver cells from chemical and biological injuries: GL can alleviate histological disorder due to inflammation and restore liver structure and function from damage due to carbon tetrachloride. The effects include lowering ALT (SGPT): 64% with normalized ALT following administration in a Japanese study and 87% in a study conducted in China. GL can reduce degeneration and necrosis, and recover glycogen and RNA of liver cells. Experimental hepatitis and cirrhosis studies on rats found that GL can promote the regeneration of liver cells and inhibit fibrosis. It can also reduce gamma-globulin and interstitial inflammation in the liver.

         Other pharmacological effects: Anti-allergic, anti-inflammatory, and detoxifying activities are all important for its use in treating viral hepatitis. Its anti-allergic and anti-inflammatory activities resemble the activities of glucocorticoid, since GL maintains the level of active corticoid in the blood and increases endogenous corticoid by inhibiting deactivation of glucocorticoid in the liver. Further, GL promotes the regeneration of inflammatory tissue in contrast with glucocorticoid, which inhibits regeneration. GL also inhibits the release of histamine from mast cells.

Caution: Although licorice is a non-toxic herb, long-term use can cause some adverse reactions in about 20% of patients. Edema, elevated blood pressure, low blood potassium, dizziness, and fatigued limbs may be seen. Patients with hypertension (high blood pressure) should not take Glycyrrhizin Capsule.
