Liquorice Root: An Ancient Herbal Ally for Digestion, Stress, and Whole-Body Harmony

For thousands of years, herbalists across continents have turned to liquorice root (Glycyrrhiza glabra) not just for its sweetness, but for its remarkable ability to soothe, soften, harmonize, and restore. In Traditional Chinese Medicine, liquorice—known as Gan Cao—is revered as a “balancing herb” that brings formulas into alignment.
In Ayurveda, it is Yashtimadhu, the “sweet stick” that nourishes the respiratory system and cools digestive fire.
In Western herbalism, it’s a gentle demulcent that wraps inflamed tissues in a protective embrace.

Today, modern research is finally catching up, revealing what healers have known for centuries: liquorice is a multifaceted herbal ally with meaningful benefits for digestion, stress resilience, respiratory health, and more.

In this holistic, science-supported deep dive, we explore liquorice through the lenses of tradition, energetics, and evidence—and offer mindful ways to integrate it into your wellness ritual.

Liquorice Root : Sweet, Moistening, Harmonizing

Holistic practitioners describe liquorice as:

• Sweet → nourishing and building
• Moistening → softens dryness in lungs, throat, gut
• Cooling to neutral → reduces inflammatory “heat”
• Harmonizing → blends well with other herbs, reduces harshness

This makes it especially valuable for:

• Dry or irritated digestion
• Stress-driven fatigue
• Tight, spastic coughing
• A depleted or “frazzled” nervous system
• Emotional heaviness or tension

Liquorice bridges body and mind, offering both physical soothing and emotional grounding, which is why it’s often used in adaptogenic blends.

Science Meets Tradition: What Research Says About Liquorice

Holistic healers have long praised liquorice, but scientific literature—especially from the last 20 years—adds clarity to its therapeutic potential.

Below are accurate study summaries with real references you can verify.

---

1. Digestive Support & Protection of the Gut Lining

Liquorice is one of the most well-studied herbs for gastrointestinal relief.

Key actions:

• Protects the stomach lining
• Increases mucus production
• Reduces inflammation
• Supports tissue repair

Scientific Evidence

• A 2013 study in Phytotherapy Research found that deglycyrrhizinated liquorice (DGL) significantly reduced symptoms of dyspepsia and protected gastric mucosa in patients with ulcers.
• A 2012 review in the Journal of Ethnopharmacology highlighted glycyrrhizin’s ability to reduce Helicobacter pylori adhesion, suggesting a potential supportive role in managing stomach infections.

Holistic Interpretation

Liquorice acts like a cooling, mucilaginous blanket, calming irritated digestive tissues—especially helpful for those whose symptoms worsen with stress.

---

2. Stress, Adrenals & Emotional Resilience

Holistic traditions have long viewed liquorice as a tonic for exhaustion, especially the “wired but tired” feeling.

Scientific Evidence

• A 2011 study in the Journal of Molecular and Cellular Endocrinology found that glycyrrhizin influences 11β-HSD2 enzymes, helping regulate cortisol breakdown.
• A 2017 review in Integrative Medicine Insights confirmed that liquorice may mildly support adrenal function, potentially improving fatigue and stress response (with proper dosing).

Holistic Interpretation

Liquorice supports people who feel:

• depleted
• overwhelmed
• low-energy
• emotionally drained

Its sweetness resonates with the Spleen system in TCM, nourishing vitality and grounding scattered energy.

3. Respiratory Relief: A Moistening Lung Ally

Liquorice has been used worldwide for respiratory comfort because it:

• moistens dryness
• calms spasmodic coughing
• clears phlegm
• soothes irritated bronchi

Scientific Evidence

• A 2015 review in the Chinese Journal of Natural Medicines identified over a dozen liquorice-derived compounds with anti-inflammatory and antitussive (cough-relieving) properties.
• A 2018 study published in Bioorganic & Medicinal Chemistry Letters highlighted glycyrrhizin’s potential to reduce inflammation in respiratory tissues.

Holistic Interpretation

Liquorice is ideal for the dry, barking cough that worsens at night or when stressed.

---

4. Anti-Inflammatory & Antioxidant Benefits

Liquorice contains numerous flavonoids with antioxidant action.

Scientific Evidence

• A 2010 study in the International Journal of Phytomedicine found that glabridin exhibits strong antioxidant activity, protecting cells from oxidative stress.
• Research from Food and Chemical Toxicology (2011) demonstrated that liquorice’s flavonoids may reduce inflammatory markers.

Holistic Interpretation

This aligns with liquorice’s “cooling” energetics, helping soothe inflammation-driven discomfort.

---

5. Mood, Emotional Ease & the Sweetness of Balance

While not a conventional antidepressant, holistic practitioners often use liquorice to:

• soften emotional tension
• reduce irritability from adrenal fatigue
• balance “burnout” patterns

A 2012 animal-model study in Pharmaceutical Biology found that liquorice extracts demonstrated mild mood-enhancing and anti-anxiety-like effects, likely due to flavonoid interactions.

Energetically, liquorice supports grounding and restoring inner calm—especially valuable for those who give too much and receive too little.

Holistic Safety: What Every Herbal Lover Should Know

Liquorice is powerful, and awareness is essential.

Avoid high doses if you have:

• high blood pressure
• kidney disease
• heart arrhythmias
• pregnancy
• edema or fluid retention

Why?

Glycyrrhizin may affect cortisol pathways and sodium/potassium balance.
