Origin & History
Natural habitat
Iraqi Licorice Root (Glycyrrhiza glabra) is a perennial herb native to the arid regions of Iraq and parts of the Middle East, thriving in dry, well-drained soils. Its sweet, earthy roots have been valued for centuries in traditional medicine for their soothing and restorative properties, particularly for digestive and respiratory health.
“Iraqi Licorice Root has been utilized in traditional Iraqi and Middle Eastern medicine for millennia, with evidence of its use dating back to ancient Mesopotamia. Valued for its sweetening properties and healing benefits, it is traditionally used for digestive health, respiratory support, and boosting immunity, often prepared as a soothing tea or syrup.”Traditional Medicine
Scientific Research
Research, including in vitro and some human studies, supports Iraqi Licorice Root's benefits for digestive health, respiratory function, and immune modulation, largely attributed to glycyrrhizin and flavonoids. Studies highlight its anti-inflammatory, antiviral, and demulcent properties, though further clinical trials are ongoing.
Preparation & Dosage
Traditional preparation
Forms
Traditionally consumed as teas, lozenges, syrups, or powdered extracts.
Tea Preparation
Brew 1–2 teaspoons of dried licorice root in hot water for 5-10 minutes.
Dosage
250-500 mg of deglycyrrhizinated licorice (DGL) extract, often divided into multiple doses
Typically 1-5 grams of dried root daily, or .
Contraindications
High doses or long-term use of whole licorice root may elevate blood pressure due to glycyrrhizin; DGL forms are safer for extended use.
Nutritional Profile
- Glycyrrhizin: The primary bioactive compound, responsible for its sweet taste and anti-inflammatory, antiviral, and adrenal-supporting effects.
- Flavonoids: Provide antioxidant protection and anti-inflammatory benefits.
- Saponins: Contribute to its demulcent and expectorant properties.
- Vitamin C: Supports immune function and acts as an antioxidant.
- Potassium: Essential for electrolyte balance and cardiovascular health.
How It Works
Mechanism of Action
Glycyrrhizin, a triterpene saponin that converts to glycyrrhetinic acid, primarily inhibits NF-κB and MAPK pathways, thereby reducing the production of pro-inflammatory cytokines and modulating immune cell activity. Flavonoids like glabridin and isoliquiritigenin contribute significant antioxidant effects by enhancing endogenous antioxidant enzymes and inhibiting enzymes such as COX-2 and iNOS. These compounds also support mucosal integrity and act as demulcents, providing a protective barrier.
Clinical Evidence
Research, including in vitro and some human studies, supports the benefits of Glycyrrhiza glabra for digestive health, respiratory function, and immune modulation. Studies highlight its anti-inflammatory, antiviral, and demulcent properties, largely attributed to compounds like glycyrrhizin and flavonoids. While promising, a full understanding of its efficacy, optimal dosing, and long-term safety in humans requires further robust clinical trials.
Safety & Interactions
Long-term or high-dose consumption of licorice root, particularly due to its glycyrrhizin content, can lead to side effects such as hypertension, hypokalemia, and fluid retention. It may interact with diuretics, corticosteroids, and medications for heart conditions or blood pressure, potentially exacerbating their effects or causing severe electrolyte imbalances. Licorice is contraindicated during pregnancy due to potential risks of premature birth and developmental issues, and should be avoided by individuals with kidney disease, heart failure, or severe hypertension.

Frequently Asked Questions
What makes "Iraqi" Licorice Root unique compared to other licorice?
Research indicates that Iraqi Licorice Root refers to Glycyrrhiza glabra, the common licorice species found in various regions, including Iraq. Current scientific literature does not identify unique compounds or distinctions specific to an "Iraqi" variety, so its properties are generally consistent with G. glabra from other sources.
What are the main bioactive compounds in licorice root?
The primary bioactive compounds include glycyrrhizin, a triterpene saponin responsible for its sweet taste and potent anti-inflammatory effects. Additionally, flavonoids like glabridin and isoliquiritigenin are present, contributing to its diverse pharmacological properties, including antioxidant and additional anti-inflammatory actions.
How does licorice root help soothe digestive issues?
Licorice root acts as a demulcent, forming a protective, gel-like coating over irritated mucous membranes in the digestive tract, which reduces irritation and inflammation. This action, combined with its direct anti-inflammatory properties from compounds like glycyrrhizin, helps to alleviate discomfort and promote overall gut health.
What are the potential side effects of consuming licorice root?
High doses or prolonged use of licorice root, primarily due to its glycyrrhizin content, can lead to elevated blood pressure (hypertension) and decreased potassium levels (hypokalemia). Other potential side effects include fluid retention, swelling, and in severe cases, cardiac arrhythmias due to electrolyte imbalances.
Is licorice root safe for pregnant women?
No, licorice root is generally contraindicated during pregnancy. Its compounds, particularly glycyrrhizin, have been linked to potential risks such as premature birth, adverse effects on fetal development, and hormonal imbalances, making it unsafe for use during gestation.
Does Iraqi licorice root interact with blood pressure medications or diuretics?
Iraqi licorice root contains glycyrrhizin, which can cause sodium retention and potassium loss, potentially interacting with blood pressure medications and diuretics by reducing their effectiveness or increasing adverse effects. If you take antihypertensive drugs or diuretics, consult your healthcare provider before using licorice root supplements, as dosage adjustments or monitoring may be necessary. This interaction is dose-dependent and more likely with prolonged use or high doses.
What is the recommended daily dosage of Iraqi licorice root for respiratory and digestive support?
Typical dosing for licorice root ranges from 1–2 grams of dried root per day as a tea or 500–1000 mg in standardized extract form, though optimal dosage varies based on individual health status and product concentration. Short-term use (4–6 weeks) is generally considered safer than long-term supplementation to minimize the risk of sodium retention and potassium depletion. Always follow product label directions and consult a healthcare practitioner to determine the appropriate dose for your specific health goals.
Who should avoid Iraqi licorice root supplementation?
Individuals with hypertension, kidney disease, heart conditions, or hormonal imbalances should avoid licorice root due to its sodium-retaining effects and hormonal modulatory properties. Pregnant women, breastfeeding mothers, children, and those taking medications for blood pressure, heart function, or corticosteroids should not use licorice without professional medical guidance. People with pseudoaldosteronism or a history of licorice-induced hypokalemia should completely avoid this supplement.
