Glycyrrhiza Glabra Var Persian

Glycyrrhiza glabra var. typica works primarily through glycyrrhizin, which inhibits 11-beta-hydroxysteroid dehydrogenase, preventing cortisol breakdown and extending its anti-inflammatory effects. This mechanism supports adrenal function and explains its traditional use for adrenal fatigue. Glabridin provides additional antioxidant and anti-inflammatory activity. The herb also increases mucus production in the respiratory tract, offering demulcent effects. Evidence Level: C.

Persian licorice interacts significantly with several medication classes. It potentiates corticosteroids and should not be combined with prednisone or similar drugs. Concurrent use with potassium-depleting diuretics (furosemide, hydrochlorothiazide) increases hypokalemia risk. Licorice may reduce effectiveness of antihypertensive medications and anticoagulants like warfarin. It can also interact with digoxin and oral contraceptives. Always consult a healthcare provider before combining licorice with prescription medications. Evidence Level: C.

For adults, the typical dosage is 200-400mg of deglycyrrhizinated licorice (DGL) extract daily, or 1-5g of dried root prepared as a tea. DGL formulations are preferred for long-term use as they remove glycyrrhizin, reducing hypertension risk. Traditional Persian medicine preparations may vary. Duration should be limited to 4-6 weeks unless under professional supervision. Evidence Level: C, Traditional use.

Persian licorice is considered unsafe during pregnancy. Glycyrrhizin can cross the placenta and has been associated with preterm birth and reduced fetal growth. Studies suggest that high consumption during pregnancy may affect child development and cognitive outcomes. Pregnant women should avoid licorice root supplements and limit consumption of licorice-containing products. Consult a qualified healthcare practitioner for alternative options. Evidence Level: C.

The primary side effects of Persian licorice stem from glycyrrhizin's effects on mineralocorticoid receptors. Long-term use or high doses can cause hypertension, hypokalemia (low potassium), edema, and in severe cases, cardiac arrhythmias. Symptoms may include headaches, fatigue, muscle weakness, and fluid retention. These effects are dose-dependent and typically reversible upon discontinuation. DGL extracts minimize these risks. Those with heart disease, kidney disease, or hypertension should avoid licorice. Evidence Level: C.

Persian licorice (Glycyrrhiza glabra var. typica) has been used in Unani and Persian medicine for respiratory infections, digestive ulcers, liver conditions, and adrenal support. Its demulcent properties soothe irritated mucous membranes, making it valuable for coughs and sore throats. The anti-inflammatory compounds glabridin and glycyrrhizin support liver health and reduce systemic inflammation. Traditional practitioners also use it for adrenal fatigue and as a general tonic. Evidence Level: C, Traditional use.
