Sore throats are a common ailment, often resulting from infections, allergies, or environmental factors. While various treatments exist, licorice root (Glycyrrhiza glabra) has been traditionally used across cultures for its soothing properties. This guide delves into the science behind licorice root’s effectiveness, its mechanisms, usage methods, potential risks, and comparisons with other remedies.
🌱 Understanding Licorice Root
Botanical Profile
Scientific Name: Glycyrrhiza glabra
Common Names: Licorice, Mulethi (India), Gan Cao (China)
Family: Fabaceae
Native Regions: Southern Europe, Asia, and the MediterraneanWikipediaWikipediaGlamour+1Wikipedia+1
Licorice root contains several bioactive compounds, notably glycyrrhizin, which contribute to its medicinal properties.
🔬 Mechanisms of Action
1. Anti-Inflammatory Effects
Glycyrrhizin exhibits anti-inflammatory properties by inhibiting enzymes involved in inflammation pathways, such as cyclooxygenase and lipoxygenase. This action reduces the production of pro-inflammatory mediators, alleviating throat inflammation. PMC
2. Antimicrobial Activity
Licorice root has demonstrated antimicrobial effects against various pathogens, including Streptococcus pyogenes, a common cause of sore throats.
3. Demulcent Properties
The mucilage content in licorice root provides a soothing film over mucous membranes, relieving irritation and discomfort in the throat.
4. Expectorant and Antitussive Actions
Compounds like liquiritin in licorice root act as expectorants, helping to loosen mucus, and possess antitussive properties that suppress coughing. PubMed+1ScienceDirect+1

❓ Top 10 FAQs About Using Licorice Root for Sore Throat
1. 🕒 How long does it take for licorice root to relieve a sore throat?
Licorice root can start soothing throat irritation within 30 minutes to a few hours after consumption. Most people notice noticeable relief within 2–3 days of consistent use (2–3 times daily). However, the results may vary depending on the severity of the condition and the method of use (tea, gargle, or lozenges).
2. 🤰 Is licorice root safe during pregnancy or breastfeeding?
No. Licorice root is not recommended during pregnancy or lactation. Glycyrrhizin may interfere with hormonal balance and has been linked to preterm labor and developmental risks in some studies. Always consult your OB-GYN before using herbal remedies during pregnancy or breastfeeding.
3. 👧 Can children use licorice root for sore throat?
Licorice root may be used with pediatrician approval for children over the age of 6, typically in the form of tea or diluted gargle. Avoid using concentrated extracts or giving it to very young children due to the risk of glycyrrhizin-related side effects like high blood pressure.
4. 💊 Can I take licorice root if I’m already on medications?
Use caution. Licorice root may interact with:
Blood pressure medications
Diuretics
Corticosteroids
Hormonal therapies
Consult a doctor or pharmacist before use to prevent drug interactions or electrolyte imbalances.
5. ❌ Are there any side effects of licorice root?
Yes. Prolonged or high-dose use of licorice root can cause:
High blood pressure
Headaches
Fatigue
Water retention (edema)
Low potassium (hypokalemia)
To minimize risk, use only for short periods (max 7–10 days) and avoid concentrated forms unless prescribed.
6. 🫖 How many times can I drink licorice root tea per day for sore throat?
You can safely consume 1–3 cups per day, spaced evenly throughout the day. Limit to 7 days of continuous use unless advised by a healthcare provider. Always follow dosage recommendations to avoid glycyrrhizin toxicity.
7. 🧪 Is there scientific research supporting licorice for sore throat?
Yes. Several peer-reviewed studies and trials suggest that:
Glycyrrhizin inhibits bacterial and viral replication
Licorice-based gargles reduce post-operative sore throat incidence
Licorice mucilage coats and soothes irritated mucous membranes
Sources: Journal of Ethnopharmacology, PubMed Central, and Mount Sinai Health Library.
8. 🔁 Can I combine licorice root with other remedies like honey or ginger?
Absolutely! Combining licorice root tea with:
🍯 Honey (antibacterial, soothing)
🌿 Ginger (anti-inflammatory)
🍋 Lemon (Vitamin C)
…can enhance its throat-soothing effects. However, avoid combining with other herbs that also affect potassium levels (e.g., senna, dandelion) unless under supervision.
