Is Liquorice Good for Acid Reflux? Benefits and Risks Explained

Acid reflux can turn a delicious meal into a painful experience, leaving millions searching for natural remedies to ease their discomfort. Among the many traditional remedies, liquorice root has gained attention for its potential to soothe the burning sensation of acid reflux. But does this sweet root actually help, or could it potentially make symptoms worse? This comprehensive guide explores the relationship between liquorice and acid reflux, examining both the potential benefits and risks.

Understanding Acid Reflux

Acid reflux occurs when stomach acid flows back into the esophagus, causing irritation and that characteristic burning sensation known as heartburn. This common digestive issue affects approximately 20% of Americans regularly, with symptoms ranging from mild discomfort to severe pain that interferes with daily activities and sleep.

The lower esophageal sphincter (LES), a ring of muscle between the esophagus and stomach, normally prevents stomach contents from flowing upward. When this sphincter weakens or relaxes inappropriately, acid reflux occurs. Triggers can include certain foods, obesity, pregnancy, smoking, and even stress.

Common Symptoms of Acid Reflux

Beyond the telltale burning sensation in the chest, acid reflux can manifest in several ways. Many sufferers experience regurgitation—the sensation of stomach contents or sour liquid backing up into the throat or mouth. Other symptoms include difficulty swallowing, chronic cough (especially at night), hoarseness, and the feeling of a lump in the throat. Left untreated, chronic acid reflux can lead to complications like esophagitis, Barrett's esophagus, or even esophageal cancer.

Understanding these symptoms is crucial for recognizing when to seek treatment and for evaluating whether natural remedies like liquorice might be beneficial for your specific situation.

Liquorice: A Traditional Remedy

Liquorice (also spelled licorice) comes from the root of Glycyrrhiza glabra, a flowering plant native to parts of Europe and Asia. For thousands of years, this sweet root has been used in traditional medicine systems across various cultures, from ancient Egypt to traditional Chinese medicine.

The distinct sweet flavor—about 50 times sweeter than sugar—comes from glycyrrhizin, the main active compound in liquorice. Beyond its use as a flavoring agent in candies and beverages, liquorice has been employed to treat various ailments, including digestive issues, respiratory problems, and inflammatory conditions.

Active Compounds in Liquorice

Liquorice contains several bioactive compounds that contribute to its potential health benefits. Glycyrrhizin, as mentioned, is the primary active component, but the root also contains flavonoids, isoflavones, and chalcones with antioxidant and anti-inflammatory properties. These compounds work together to create liquorice's therapeutic effects, particularly its ability to soothe mucous membranes and reduce inflammation—properties that make it potentially beneficial for acid reflux sufferers.

Traditional Uses for Digestive Health

Throughout history, liquorice has been specifically used to address digestive complaints. In traditional Chinese medicine, it's often included in formulas for "harmonizing" the digestive system. European herbalists have long recommended liquorice for stomach ulcers and indigestion. This historical use provides some foundation for modern interest in liquorice as a remedy for acid reflux, though traditional use alone doesn't constitute scientific evidence.

These traditional applications have inspired modern research into liquorice's potential benefits for digestive health, including its possible role in managing acid reflux symptoms.

How Liquorice May Help Acid Reflux

The potential benefits of liquorice for acid reflux stem from several mechanisms that address both symptoms and underlying causes. Research suggests that liquorice may help strengthen the mucosal lining of the esophagus and stomach, potentially creating a protective barrier against stomach acid damage.

Additionally, some studies indicate that liquorice compounds may help tighten the lower esophageal sphincter, reducing the likelihood of acid backing up into the esophagus. This dual action—protecting tissues and preventing reflux—makes liquorice an intriguing natural option for those seeking alternatives to conventional medications.

Anti-inflammatory Properties

One of liquorice's most well-documented effects is its anti-inflammatory action. Inflammation plays a significant role in the discomfort associated with acid reflux, as stomach acid irritates the esophageal lining. Liquorice's anti-inflammatory compounds may help reduce this inflammation, potentially decreasing pain and promoting healing of irritated tissues.

Research published in the Journal of Ethnopharmacology has demonstrated that glycyrrhizin and other liquorice compounds can inhibit inflammatory pathways, which may explain some of the relief reported by acid reflux sufferers who use liquorice products.

Mucus Production and Tissue Protection

Another way liquorice may benefit those with acid reflux is by stimulating the production of mucus in the stomach and esophagus. This increased mucus can form a protective layer that shields delicate tissues from stomach acid. Some studies suggest that liquorice compounds can enhance the quality and quantity of protective mucus, potentially reducing damage from acid exposure.

This mucus-stimulating effect, combined with liquorice's ability to promote cell regeneration, may help heal damaged esophageal tissue—a significant benefit for those with chronic reflux who have experienced erosion of the esophageal lining.

DGL Liquorice: A Safer Alternative

When discussing liquorice for acid reflux, it's crucial to distinguish between regular liquorice and deglycyrrhizinated liquorice (DGL). DGL is a specially processed form of liquorice with the glycyrrhizin compound removed. This processing is significant because glycyrrhizin, while contributing to liquorice's therapeutic effects, is also responsible for most of its potential side effects.

DGL retains many of the beneficial compounds for digestive health while eliminating the component most associated with adverse effects. For this reason, DGL is typically the recommended form of liquorice for those with acid reflux or other digestive complaints.

How DGL Works

DGL works primarily by stimulating the protective mechanisms of the digestive tract. It increases both the quantity and quality of mucus-producing cells in the stomach and esophagus, creating a thicker protective barrier against stomach acid. Additionally, DGL appears to support the integrity of the esophageal and stomach lining, potentially helping to heal damaged tissue.

Unlike some acid reflux medications that reduce acid production (which can interfere with proper digestion), DGL focuses on protection and healing without disrupting the digestive process. This makes it an attractive option for those seeking to address reflux symptoms while maintaining digestive function.

Potential Risks and Side Effects

Despite its potential benefits, regular (non-DGL) liquorice comes with significant risks, particularly when consumed in large amounts or over extended periods. The glycyrrhizin in regular liquorice can cause serious side effects, including elevated blood pressure, potassium depletion, fluid retention, and hormonal imbalances. These effects are dose-dependent and more likely to occur with prolonged use.

For those with certain medical conditions—including hypertension, kidney disease, liver disease, or heart failure—regular liquorice can pose serious health risks. Pregnant women should also avoid regular liquorice, as some research suggests it may increase the risk of premature birth.

Who Should Avoid Liquorice

Several groups should exercise particular caution with liquorice products. People taking certain medications, including diuretics, corticosteroids, or drugs for heart rhythm problems, should avoid liquorice due to potential interactions. Those with hormone-sensitive conditions like breast cancer, uterine fibroids, or endometriosis should also avoid regular liquorice, as it can have estrogen-like effects.

Even DGL, while generally considered safer, may not be appropriate for everyone. Anyone with a known allergy to plants in the legume family should approach liquorice products with caution. As with any supplement, it's always best to consult with a healthcare provider before beginning use, especially if you have existing health conditions or take medications.

Incorporating Liquorice into Your Acid Reflux Management Plan

If you're considering liquorice for acid reflux, DGL supplements are typically the safest option. These are available in various forms, including chewable tablets, capsules, and powders. The typical recommended dosage is one or two tablets (usually 380-400mg each) taken before meals and at bedtime, though this can vary by product and individual needs.

When selecting a DGL supplement, look for quality products from reputable manufacturers. Some individuals find that integrating DGL with other gut-friendly supplements enhances their results. For example, many people with digestive issues have found success combining DGL with digestive enzymes and probiotics, such as those offered by Casa de Sante, which are specifically formulated to be low FODMAP and gut-friendly for those with sensitive digestive systems.

A Holistic Approach to Acid Reflux

While supplements like DGL liquorice may help manage acid reflux symptoms, they work best as part of a comprehensive approach. Dietary modifications remain the cornerstone of acid reflux management. This typically includes avoiding trigger foods (such as spicy foods, citrus, tomatoes, chocolate, and caffeine), eating smaller meals, and not lying down immediately after eating.

For those with food sensitivities contributing to their reflux, following a specialized diet plan can make a significant difference. Casa de Sante's personalized meal plans can be particularly helpful, as they're designed to eliminate common trigger foods while ensuring nutritional adequacy. Their low FODMAP protein powders can also be a gentle way to increase protein intake without aggravating reflux symptoms.
