What the Research Actually Says About Licorice Root

A warm, plain-language look at the clinical research behind our most-loved herb — no jargon required.

If you’ve ever looked at a Traditional Chinese Medicine (TCM) herbal formula, there is a very high chance you spotted Licorice Root (Glycyrrhiza glabra or Glycyrrhiza uralensis). Known in TCM as Gan Cao (甘草), or "sweet grass," it is often referred to as the "Great Harmonizer." In fact, ancient texts note that licorice root is included in a vast majority of traditional herbal blends because of its unique ability to bring balance to other botanicals.

At Naturin2, licorice root is one of our star ingredients. But you don't have to rely solely on thousands of years of traditional practice to appreciate it. Modern research—documented in peer-reviewed scientific journals archived on the National Institutes of Health (NIH / PubMed) database—continues to examine how this ancient botanical supports everyday human health.

Let’s take a plain-language look at what the clinical literature and modern science actually say about licorice root.

1. Active Compounds: The Chemistry Behind the Root

To understand why researchers are so fascinated by licorice root, it helps to know what is inside it. Modern phytochemical analysis archived on NIH databases reveals that licorice root contains over 300 active bioactive compounds.

The two primary groups of interest are:

  • Glycyrrhizin (Glycyrrhizic Acid): A triterpenoid saponin responsible for licorice’s natural sweetness and much of its immune-modulating properties.

  • Flavonoids (such as Glabridin and Liquiritin): Potent plant-based antioxidants that help neutralize free radicals and protect cells from everyday oxidative stress.

In TCM, these components are believed to nourish Spleen Qi (digestive energy) and calm internal dryness. In modern biochemistry, scientists view them as natural allies for cellular defense and tissue comfort.

2. Supporting Gut Comfort & Digestive Harmony

In traditional practice, Gan Cao is routinely recommended to soothe the stomach and support smooth digestion.

Modern clinical research archived via NIH/PMC literature shows why this traditional wisdom holds up:

  • Mucosal Protection: Studies suggest that compounds in licorice root help encourage the production of gastric mucin—the protective lining that shields the stomach and digestive tract from everyday acid and digestive friction.

  • Soothing Tissue Comfort: Clinical trials evaluating licorice extracts (including deglycyrrhizinated licorice, or DGL) demonstrate its ability to promote stomach comfort and ease occasional mild indigestion or bloating after meals.

TCM Meets Science: What ancient practitioners described as "tonifying the Spleen and Stomach," modern researchers observe as supporting the structural integrity of the digestive lining and maintaining healthy gut microbial balance.

3. Immune Balance & Upper Respiratory Wellness

When seasons change or daily stress builds up, keeping your immune system balanced is essential. Licorice root has long been used in traditional winter tonics to ease throat tickles and support clear breathing.

According to research reviews published on PubMed:

  • Immunomodulatory Action: Bioactive polysaccharides and glycyrrhizin in licorice root have been shown to help modulate immune cell activity (such as macrophages and T-cells), encouraging a measured, balanced immune response rather than an overactive one.

  • Respiratory Demulcent: Studies note that licorice acts as a natural demulcent—a soothing substance that forms a protective film over mucous membranes, helping to soothe throat irritation and support upper respiratory tract comfort.

4. The Harmonizer: Why Synergy Matters

In Western herbalism, herbs are often taken as single isolates. But in TCM—and inside every vial of Naturin2's Herbal Tonic —herbs are formulated to work together in synergy.

In traditional literature, Gan Cao is celebrated for its ability to:

  1. Reduce Harshness: Soften the intense qualities of other potent botanicals.

  2. Guide Ingredients: Help coordinate how nutrients interact within the body.

  3. Extend Action: Help sustain the body's absorption of active plant compounds.

Modern pharmacological reviews on NIH back up this ancient principle, showing that combining licorice flavonoids with other botanical extracts can enhance overall bioactivity while maintaining gentle digestive tolerance.

The Naturin2 Difference: Science-Backed Herbal Quality

While raw licorice root has incredible benefits, balance and preparation are key. Consuming excessive amounts of unprocessed raw licorice can lead to unwanted sodium retention.

Formulated by medical researchers and trusted by families for over 30 years, Naturin2 uses expertly extracted, standardized botanical blends to deliver the soothing, harmonizing benefits of licorice root safely and consistently in every pre-measured daily dose.
