Licorice Root for Gut Soothing: Evidence-Based Benefits and Use

Many people experience occasional bloating, heartburn, or discomfort after meals and look for gentle, plant‑based options to ease these symptoms. Licorice root, a traditional herb used in various cultures, has attracted attention for its possible soothing effects on the gastrointestinal tract.

While anecdotal reports are plentiful, it is important to examine what the research actually says about licorice root’s mechanisms, appropriate use, and safety considerations. This article presents an evidence‑based overview to help you decide whether licorice root might fit into your gut‑health routine.

Why it matters

Maintaining a healthy weight supports overall digestive function, as excess abdominal fat can increase intra‑abdominal pressure and contribute to reflux or sluggish motility. The CDC notes that achieving and sustaining a healthy weight is linked to better gastrointestinal outcomes, making lifestyle factors a relevant backdrop when evaluating any supplemental approach.

The science

Licorice root (Glycyrrhiza glabra) contains several bioactive compounds, the most studied being glycyrrhizin. Glycyrrhizin can constitute up to 10 % of dried licorice root and exhibits anti‑inflammatory properties by inhibiting the enzyme 11β‑hydroxysteroid dehydrogenase, which modulates cortisol activity in gut tissues. Reduced cortisol signaling may lessen mucosal irritation and promote a calmer intestinal environment.

Physical activity also influences gut health by enhancing motility and supporting a diverse microbiome. The World Health Organization highlights that regular movement aids digestive transit, which complements the soothing actions of compounds like glycyrrhizin.

Results vary from person to person, and while laboratory and animal studies show promise, human clinical trials are limited and often involve specific formulations such as deglycyrrhizinated licorice (DGL), which has had the glycyrrhizin removed to reduce the risk of hypertension.

Practical strategies

Choose the right form

For gut soothing, many practitioners recommend deglycyrrhizinated licorice (DGL) tablets or powders because they retain the flavonoid content believed to support mucosal healing while minimizing glycyrrhizin‑related side effects. Look for products that specify the DGL content and have been tested for purity.

If you prefer a traditional preparation, a tea made from sliced licorice root can be consumed in moderation; however, the glycyrrhizin concentration in tea is harder to control, so limit intake to one cup per day and monitor blood pressure.

Follow evidence‑based dosing

Clinical studies on DGL for symptoms such as heartburn have used doses ranging from 380 mg to 760 mg taken before meals, up to three times daily. Starting at the lower end allows you to assess tolerance. Always follow the manufacturer’s instructions or the guidance of a healthcare professional.

Because glycyrrhizin can cause potassium loss and elevated blood pressure at high doses, avoid exceeding recommended amounts and discontinue use if you notice swelling, headaches, or irregular heartbeat.

Integrate with supportive habits

Licorice root works best as part of a broader gut‑friendly routine. Consider pairing it with:

• A balanced diet rich in fiber and fermented foods, as discussed in our Evidence-Based Gut Healing Diets for SIBO Recovery Guide.
• Regular physical activity, which the WHO recommends for overall digestive health.
• Adequate hydration to support mucosal integrity.

These complementary practices may enhance the soothing effects of licorice root while promoting long‑term gastrointestinal resilience.

Common mistakes

• Using regular licorice root extracts without removing glycyrrhizin, which can lead to hypertension or low potassium levels.
• Taking licorice root on an empty stomach in large amounts, increasing the risk of gastrointestinal irritation.
• Combining licorice root with other supplements that also affect blood pressure, such as stimulant herbs, without professional oversight.
• Expecting immediate results; mucosal support often requires consistent use over several weeks.

When to seek help

If you experience persistent pain, vomiting, unexplained weight loss, or changes in bowel habits lasting more than a few weeks, consult a healthcare provider. These symptoms may indicate an underlying condition that requires medical evaluation rather than self‑management with herbs.

Key takeaways

• Deglycyrrhizinated licorice (DGL) is the preferred form for gut soothing due to its reduced glycyrrhizin content.
• Typical DGL doses range from 380 mg to 760 mg before meals, up to three times daily.
• Licorice root’s potential benefits are linked to anti‑inflammatory flavonoids that may calm mucosal irritation.
• Lifestyle factors such as maintaining a healthy weight (per CDC) and regular physical activity (per WHO) support overall digestive health and can complement herbal approaches.
• Results vary from person to person; monitor your response and discontinue use if adverse effects appear.

Frequently asked

Can I drink licorice tea every day?

Moderate consumption-about one cup per day-is generally considered safe for most people, but daily intake should be limited to avoid excessive glycyrrhizin exposure, especially if you have hypertension or kidney concerns.

Is licorice root safe during pregnancy?

Due to potential hormonal effects and the risk of elevated blood pressure, licorice root is not recommended during pregnancy unless specifically advised by a qualified healthcare provider.

How long should I try licorice root before judging its effect?

Many studies evaluate outcomes over four to eight weeks of consistent use. Give it at least a month while tracking symptoms, and adjust dosage only under professional guidance.

Does licorice root interact with medications?

Yes, glycyrrhizin can affect the metabolism of certain drugs, including corticosteroids, diuretics, and blood pressure medications. Discuss any supplement use with your pharmacist or doctor if you take prescription medicines are part of your regimen.
