potassium and calcium salts of glycyrrhitinic acid. Flavonoid rich fractions include
liquirtin, isoliquertin, liquiritigenin and rhamnoliquirilin1. |
| PHARMACOLOGY |
Extensive reports are available on modern
pharmacological research on this drug supporting its claims in older literature as a broad
spectrum entity in many pharmacopoeias.Recent studies report the antiinflammatory action
of glycyrrhetinic acid2. Both liquorice extract and
glycyrrhetinic acid are shown to have desoxycorticosterone3 and
ACTH-like effects, though with less toxicity than cortisone4,
encouraging its use as an antiarthritic agent5, in addisions
disease6 and simmonds disease7. It
prevented the development of experimental cirrhosis in rats8. It
is also found to be of much use as an antioxidant9
antihepatotoxic agent10. |
| THERAPEUTIC
USES |
In Ayurveda, it is used extensively as a
demulcent, mild expectorant and antiinflammatory agent. It is indicated in sore throat
with hoarseness of voice and cough, acid peptic disease, chronic liver disease, and as a
general tonic. |
