Licorice Root: Benefits, Uses, and Safety for Digestive and Respiratory Health

Quick Answer

Licorice root can help soothe digestive discomfort and support respiratory health, but it requires careful use. For daily support, choose deglycyrrhizinated licorice (DGL) or use it short-term; if you have high blood pressure or are pregnant, talk to your doctor first.

If you're dealing with occasional heartburn, indigestion, or a scratchy throat, licorice root might be the herbal ally you're looking for. This sweet-tasting root has been used for centuries in traditional medicine, and modern research is catching up to its potential benefits for digestive and respiratory health.

But licorice root isn't a one-size-fits-all remedy. It contains a compound called glycyrrhizin that can cause side effects like high blood pressure and low potassium when taken in large amounts or over long periods. That's why it's crucial to know how to use it safely and when to choose a different option.

What Licorice Root Can Do for Digestion

Licorice root has a long history of use for soothing the digestive tract. It's often used to relieve heartburn, acid reflux, and indigestion. The root contains compounds that may help protect the stomach lining and reduce inflammation, which can ease discomfort after meals.

If you're considering licorice for digestive support, you might want to look for deglycyrrhizinated licorice (DGL), which has the glycyrrhizin removed. DGL is gentler on the body and less likely to cause side effects, making it a better choice for regular use. However, licorice root in its whole form can still be used for short periods under the guidance of a healthcare provider.

• For occasional heartburn, try a cup of licorice root tea after meals.
• Chewable DGL tablets are a convenient option for on-the-go relief.
• Avoid using whole licorice root for more than 4-6 weeks without professional advice.

Licorice Root for Respiratory Health

Licorice root is also a traditional remedy for coughs and sore throats. It can help soothe irritated mucous membranes and may act as an expectorant, making it easier to clear phlegm. This makes it useful during cold and flu season or for seasonal allergies.

You can take licorice root as a tea, tincture, or in capsule form. For a sore throat, gargling with a cooled licorice tea can be soothing. If you're using it for a cough, a warm tea may help loosen congestion and calm the tickle in your throat.

• Add a slice of fresh licorice root to hot water for a simple tea.
• Combine licorice with marshmallow root for extra soothing benefits.



• For best results, start with small doses and see how your body responds.

How to Choose the Right Licorice Root Product

Licorice root comes in several forms: dried root for tea, powder, capsules, and liquid extracts. When choosing a product, consider your needs and preferences. For tea, dried cut root is ideal; for convenience, capsules or extracts are easier to take on the go.

Quality matters. Look for products from reputable brands that provide the botanical name (Glycyrrhiza glabra) and indicate the part used. If you're looking for a bulk herb, Earth Pharmaceuticals offers licorice root in various forms, though you'll want to check the specific product details to ensure it fits your needs.

• Check the label for the botanical name to ensure you're getting true licorice.
• If you have high blood pressure, opt for DGL or avoid licorice altogether.
• Store dried licorice root in a cool, dry place to maintain potency.

Licorice Root Safety: Who Should Avoid It?

Licorice root is not safe for everyone. People with high blood pressure, heart disease, kidney issues, or low potassium levels should avoid it. Pregnant women and those taking certain medications, like diuretics or blood pressure drugs, should also steer clear or consult a doctor first.

Even healthy individuals should use licorice root in moderation. Overuse can lead to side effects like headaches, fatigue, and swelling. Stick to recommended doses and don't use it continuously for more than a few weeks.

• Always start with a low dose to see how your body reacts.
• If you experience any unusual symptoms, stop using licorice and seek medical advice.
• When in doubt, talk to a healthcare provider before adding licorice to your routine.

Diagnosing Your Licorice Root Needs

• Symptom: Occasional heartburn or indigestion: You may be looking for a natural way to soothe your stomach after meals. Licorice root, especially in DGL form, can help coat and calm the digestive tract. Try a cup of licorice tea or a DGL supplement after meals. If symptoms persist beyond a few weeks, consult a doctor.
• Symptom: Persistent cough or sore throat: A scratchy throat or a nagging cough can be relieved by licorice root's soothing and expectorant properties. A warm tea can help loosen mucus and ease irritation. Sip licorice tea throughout the day. If your cough lasts more than a week or comes with fever, see a healthcare provider.
• Symptom: You have high blood pressure or are pregnant: Licorice root contains glycyrrhizin, which can raise blood pressure and affect potassium levels. Pregnant women are also advised to avoid it due to potential risks. Stop and choose another option. Consider DGL (which is safer) or other herbs like marshmallow root or chamomile. Always talk to your doctor first.
