The Risks of Daily Licorice Root Consumption
While occasional consumption of licorice root tea or supplements is generally considered safe for healthy individuals, regular, long-term intake is strongly discouraged by medical experts. The primary concern stems from glycyrrhizin, a compound in licorice root that inhibits an enzyme that breaks down cortisol. This can cause the body to retain sodium and lose potassium, leading to significant health issues over time.
Potential Adverse Effects
- Hypertension and Electrolyte Imbalance: The most documented risk of prolonged licorice use is a rise in blood pressure and a drop in potassium levels (hypokalemia). This can lead to a condition called pseudohyperaldosteronism, which mimics the effects of excess aldosterone.
- Cardiovascular Complications: Severe hypokalemia and hypertension can lead to more serious heart issues, including irregular heart rhythms (arrhythmia), heart failure, and in rare cases, cardiac arrest.
- Hormonal Disruption: By affecting cortisol metabolism, licorice root can interfere with hormonal balance. This can have particular implications for individuals with hormone-sensitive conditions or those on hormonal therapies.
- Kidney and Liver Issues: People with pre-existing kidney or liver disease are at higher risk, as their bodies may have more difficulty processing and clearing the compounds in licorice.
- Pregnancy and Breastfeeding: Licorice root is considered unsafe for pregnant women and should be avoided. Excessive intake has been linked to negative pregnancy outcomes and developmental issues in children. Little is known about its safety during breastfeeding.
Medications that Interact with Licorice Root
For those on medication, the risks of daily licorice root consumption are compounded by potential drug interactions. These can decrease the efficacy of prescribed medications or increase the risk of adverse effects.
Commonly Interacting Medications:
- Diuretics (Water Pills): Licorice can lower potassium levels, and so can diuretics. Taking both together can cause dangerously low potassium levels.
- Blood Pressure Medication: Since licorice can raise blood pressure, it can reduce the effectiveness of antihypertensive drugs.
- Corticosteroids: Licorice can increase the effects and side effects of corticosteroid medications by slowing their breakdown in the body.
- Blood Thinners (e.g., Warfarin): Licorice might decrease the effectiveness of blood thinners, increasing the risk of clotting.
- Digoxin: This heart medication is highly sensitive to potassium levels. The decrease in potassium caused by licorice can increase the toxicity and side effects of digoxin.
Potential Short-Term Benefits of Licorice Root
Despite the long-term risks, licorice root is known for several potential short-term benefits, often leveraged in medicinal settings or through moderated use.
- Digestive Aid: Used traditionally to soothe an upset stomach, licorice has shown promise in managing symptoms of indigestion, bloating, and heartburn.
- Peptic Ulcer Treatment: Some studies suggest that licorice extract, particularly in conjunction with other treatments, can help eradicate the H. pylori bacteria responsible for stomach ulcers.
- Sore Throat and Cough Relief: Licorice root tea is a popular remedy for soothing sore throats and relieving coughs, thanks to its anti-inflammatory properties.
- Oral Health: The antimicrobial properties of licorice root may help fight bacteria that cause plaque, cavities, and bad breath.
A Comparison of Licorice Products
Not all licorice products are created equal, with the presence of glycyrrhizin being the key differentiator for daily use.
| Feature | Glycyrrhizinated Licorice Root | Deglycyrrhizinated Licorice (DGL) |
|---|---|---|
| Glycyrrhizin Content | Contains the active compound glycyrrhizin | Glycyrrhizin is removed or reduced to undetectable levels |
| Daily Safety | Not recommended for daily or long-term use due to high risk of adverse effects | Considered safer for daily use for up to 4 months |
| Primary Risk | High blood pressure, low potassium, and hormonal effects | Minimal risk of hypertension or electrolyte imbalance |
| Benefits | Most clinical evidence links benefits to the presence of glycyrrhizin | May retain some benefits, but effectiveness may differ from whole root |
| Typical Use | Occasional or very short-term use under medical supervision | Targeted short-term treatments for conditions like GERD |
Conclusion: Can You Drink Licorice Root Every Day?
In short, no, it is not recommended to drink licorice root tea or consume regular licorice root products every day for extended periods. The high concentration of glycyrrhizin in the root poses significant risks for serious side effects, including elevated blood pressure, dangerously low potassium levels, and potential cardiac issues. While short-term, moderate use (up to four weeks) may offer certain benefits for digestion, throat irritation, and oral health, it should always be approached with caution and medical supervision, especially for individuals with underlying health conditions or those on medication. For those seeking the potential benefits without the risk of glycyrrhizin, deglycyrrhizinated licorice (DGL) is a safer alternative for longer use, though consultation with a healthcare professional is still advised. Always prioritize safety and consult a doctor to discuss appropriate dosage and duration before incorporating licorice root into a daily regimen.

What are the short-term uses for licorice root?
Licorice root is traditionally used for short-term relief from indigestion, heartburn, acid reflux, sore throats, and coughs. Its anti-inflammatory and antimicrobial properties can soothe and protect the digestive and respiratory tracts.
Who should completely avoid consuming licorice root?
Individuals with high blood pressure, heart disease, kidney or liver conditions, as well as pregnant and breastfeeding women, should avoid licorice root due to the risk of severe adverse effects. It is also contraindicated for those with low potassium levels.
Is it safe to consume deglycyrrhizinated licorice (DGL) daily?
Yes, DGL products, which have had the glycyrrhizin removed, are considered safer for daily use for a period of up to four months. Since the compound responsible for the most serious side effects is absent, it reduces the risk of hypertension and potassium imbalance.
How does licorice root affect blood pressure?
Glycyrrhizin in licorice root can cause the body to retain sodium and water while excreting potassium. This leads to an increase in blood volume and can cause elevated blood pressure, even in healthy individuals, especially with chronic use.
Can licorice root interact with my medications?
Yes, licorice root can interact with many medications, including diuretics, blood pressure drugs, corticosteroids, blood thinners, and hormonal therapies. It is crucial to consult a doctor or pharmacist to discuss potential drug interactions before taking licorice root.
What is the recommended duration for taking licorice root?
For products containing glycyrrhizin, intake should be limited to short-term, occasional use, typically no more than four weeks, and should be supervised by a healthcare provider. For deglycyrrhizinated licorice (DGL), use can extend to up to four months.
What is the recommended daily limit for glycyrrhizin intake?
Organizations like the World Health Organization (WHO) recommend limiting glycyrrhizin intake to no more than 100 mg per day for the average adult. However, since glycyrrhizin content varies widely by product, it can be difficult to measure, reinforcing the need for caution and medical guidance.
