The Potential Health Benefits of Liquorice Tea
For centuries, liquorice root has been a staple in traditional medicine systems like Ayurveda and Traditional Chinese Medicine (TCM). Its naturally sweet flavor and potent compounds translate into several health benefits when brewed into tea.
Soothes Digestive Discomfort
One of the most well-documented benefits of liquorice tea is its ability to calm digestive issues. The root's anti-inflammatory properties can help reduce irritation and inflammation in the stomach lining, offering relief from symptoms like indigestion, heartburn, and bloating. Research has also shown its potential to combat H. pylori bacteria, a common cause of peptic ulcers.
Supports Respiratory Health
For centuries, liquorice has been used as a natural remedy for respiratory ailments. The tea acts as an expectorant, helping to loosen and expel mucus from the lungs and airways. Its soothing, demulcent properties can coat a sore throat, providing relief from dry coughs and hoarseness.
Offers Anti-Inflammatory and Antioxidant Effects
Compounds found in liquorice root, such as glycyrrhizin, possess significant antioxidant and anti-inflammatory effects. Antioxidants help protect the body's cells from oxidative damage caused by free radicals, while its anti-inflammatory properties may help manage conditions involving inflammation, including skin conditions like eczema.
Aids Liver Function
Some research suggests that liquorice may offer protective benefits for the liver. It is thought to assist the liver in neutralizing toxins and may help protect against liver damage. Its antiviral properties have also been studied for their potential effect on Hepatitis A and C viruses.
The Serious Side Effects and Risks
While liquorice tea can be beneficial, its primary active compound, glycyrrhizin, can cause serious side effects if consumed in large quantities or over a prolonged period.
- High Blood Pressure and Low Potassium: The most notable risk is its effect on blood pressure. Glycyrrhizin can cause the body to retain sodium and lose potassium, leading to hypertension (high blood pressure), edema (swelling), and hypokalemia (low potassium levels). In severe cases, this can lead to irregular heart rhythms, heart failure, and even paralysis.
- Hormonal Interference: Excessive liquorice can disrupt hormonal balance, affecting cortisol levels and potentially impacting women's menstrual cycles and hormone-sensitive conditions.
- Pregnancy and Breastfeeding Concerns: Due to its potential hormonal effects and the risks associated with high cortisol levels, liquorice tea is generally not recommended during pregnancy or breastfeeding. Studies have linked high consumption during pregnancy with adverse outcomes.
- Drug Interactions: Liquorice can interfere with a number of medications, including blood pressure drugs, diuretics, corticosteroids, and blood thinners. Anyone on regular medication should consult a doctor before consuming it.
- Kidney Disease: Individuals with pre-existing kidney disease should avoid liquorice tea, as it can worsen their condition.
Deglycyrrhizinated Liquorice (DGL) Tea: A Safer Alternative
For those seeking the digestive benefits without the glycyrrhizin-related risks, Deglycyrrhizinated Liquorice (DGL) tea is an alternative. This form of liquorice has had the glycyrrhizin removed, making it safer for long-term use, though its exact benefits and potency compared to regular liquorice are still being studied. DGL products are typically available in tablet form, but some tea blends might specify a low glycyrrhizin content.

Conclusion: Consume with Caution
Are liquorice tea bags good for you? The answer depends entirely on your health status and how you consume them. In moderation and for short periods, liquorice tea can be a soothing remedy for a sore throat or an upset stomach. However, the potent compound glycyrrhizin carries significant risks, particularly for those with heart conditions, high blood pressure, or who are pregnant. It is crucial to be aware of the dosage and duration of use. For long-term or regular consumption, consulting a healthcare professional is essential. Ultimately, enjoying liquorice tea requires a mindful approach to ensure you reap the benefits without suffering the consequences of overconsumption.
How to Enjoy Liquorice Tea Safely
- Consume in Moderation: Limit your intake to 1-3 cups per day for short periods (no more than 4-6 weeks).
- Monitor Your Body: Be aware of any symptoms like swelling, headaches, or muscle weakness that could signal a negative reaction.
- Consult a Doctor: If you have any underlying health conditions, especially high blood pressure, heart disease, or kidney problems, consult a healthcare provider before use.
- Check the Label: Ensure you are not consuming excessive glycyrrhizin. Some products specify their glycyrrhizin content.
- Consider Alternatives: If you have health concerns, consider a deglycyrrhizinated (DGL) liquorice product, which has a much lower risk profile.
