Quick answer: licorice root tea is a naturally sweet, earthy infusion made from dried licorice root (gan cao). In TCM it has traditionally been used in formulas as a harmonizing ingredient, but that traditional role is not proof that a cup treats a symptom. If you want to try the flavor, make a weak, occasional cup; daily use is not a safe default because licorice may raise blood pressure and lower potassium.
Is this guide for you?
This guide is for a curious tea drinker deciding whether licorice’s mellow sweetness suits their cupboard. It is not a guide to treating cough, digestion, fatigue, or any diagnosed condition. If your goal is a minty, caffeine-free after-dinner drink, see peppermint tea; if you want a warming, familiar brew, compare ginger tea.
The decision: choose, consider, start
- Choose this if: you enjoy a naturally sweet, rounded herbal flavor and have checked that licorice is appropriate for you.
- Consider another option if: you want an everyday tea, need to limit sodium or manage blood pressure, take regular medication, or are pregnant. Plain warm water or a non-licorice infusion is simpler.
- Start with: a small, weak cup once—not a concentrated extract or multi-herb formula—and notice taste and tolerance.
The TCM lens: traditional framework, not anatomy
In traditional Chinese materia medica, gan cao is commonly described as sweet in flavor and neutral in nature, with traditional associations to the Lung, Spleen, Heart, and Stomach channels. TCM texts describe it as harmonizing ingredients in a formula and supporting what the tradition calls qi. These are concepts within a historical medical framework, not anatomical pathways or established explanations of how a tea works in the body. Traditions vary by source and preparation.
The modern food lens: known, limited, and unknown
Licorice root contains glycyrrhizin, a compound that can have real physiological effects. Repeated or high exposure may cause fluid retention, increased blood pressure, and reduced potassium; serious complications are possible, particularly with certain medicines or health conditions. Deglycyrrhizinated licorice (DGL) products are different products and are not interchangeable with root tea. A culinary infusion has no standardized active dose, and there is not good evidence that a home-brewed cup provides a particular health outcome. “Natural” does not mean risk-free.

| Option | Flavor and use | Decision note |
|---|---|---|
| Licorice root | Sweet, rounded, root-like | Occasional taste experiment only if safe for you; meaningful interaction cautions. |
| Peppermint | Cool, aromatic | No licorice, but mint may not suit everyone with reflux. |
| Ginger | Warming, peppery | Easy to adjust by slice count; check individual medicine or condition concerns. |
Try it once: a mild kitchen infusion
- Use 1–2 g food-grade dried licorice root (roughly a few thin pieces) and 300 ml water. Do not substitute concentrated extract or powder.
- Rinse quickly if dusty. Bring water and root to a gentle simmer for 5–10 minutes; strain. Shorter steeping makes a lighter, less sweet cup.
- Let it cool to a comfortable temperature. Taste it plain first; no sweetener is usually needed. If you want a blend, add a slice of fresh ginger, but keep the licorice amount small.
- Have it with or after food, earlier in the day, and do not make it a daily routine without professional advice. Observe taste, stomach comfort, and any unusual swelling, headache, or palpitations; stop and seek advice if concerning symptoms occur.
This amount is a culinary recipe, not a medical dose. Licorice species and products differ, so follow the package’s food-use directions and do not increase the amount to chase an effect.
Troubleshooting and personalization
- Too sweet or strong? Use less root or simmer for less time; dilute with hot water.
- Want a daily drink? Choose a tea without licorice rather than repeating this brew.
- Not sure what is in a blend? Check the ingredient list for licorice, gan cao, or Glycyrrhiza, and ask a pharmacist if you use medication.
Tea preference is personal. There is no need to interpret a taste response as a diagnosis or to match a tea to a TCM “type.”
Specific safety boundaries
Avoid licorice root tea unless a clinician who knows your situation approves it if you are pregnant or breastfeeding; have high blood pressure, heart disease, kidney disease, or low potassium; or use diuretics, corticosteroids, digoxin, blood-pressure medicines, or other regular prescriptions. This is not an exhaustive interaction list—ask a pharmacist to review your exact products. Stop use and seek medical advice for swelling, muscle weakness, severe headache, chest symptoms, or an irregular heartbeat. Keep herbal products away from children unless a qualified professional advises otherwise.
