Best Tea for a Sore Throat: 8 Teas That Actually Help (and Why)

A sore throat sends most Canadians reaching for tea — and the instinct is backed by science. Warm liquids soothe irritated mucous membranes, and many herbal teas contain compounds with genuine anti-inflammatory, antimicrobial, or analgesic properties. Here are the 8 best teas for a sore throat, ranked by the strength of the evidence behind them.

1. Honey-lemon ginger tea

The gold standard home remedy. A 2020 BMJ Evidence-Based Medicine review found that honey is as effective as over-the-counter cough suppressants for upper respiratory symptoms. Ginger contains gingerols with anti-inflammatory properties, and lemon provides vitamin C.

How to brew: Fresh ginger slices (1 inch) steeped in boiling water for 10 minutes, then stir in 1 tbsp honey and a squeeze of lemon after cooling slightly. Do not add honey to boiling water — it degrades the beneficial enzymes.

2. Chamomile tea

Chamomile contains apigenin, an antioxidant with anti-inflammatory and mild sedative properties. A 2011 study in Molecular Medicine Reports found that chamomile tea can reduce pain and inflammation in the throat. The warmth and steam also help hydrate irritated tissue.

Canadian pick: Celestial Seasonings Chamomile (widely available at Sobeys and Loblaws) or David’s Tea Organic Chamomile.

3. Peppermint tea

Peppermint contains menthol, which has a natural numbing and cooling effect on sore throat pain. It also acts as a decongestant, thinning mucus. The menthol in peppermint tea won’t cure an infection, but it provides significant symptomatic relief.

Canadian pick: Twinings Pure Peppermint or Traditional Medicinals Peppermint (available at most Canadian grocery stores).

4. Slippery elm tea

Slippery elm bark contains mucilage, a gel-like substance that coats and soothes the throat lining. It’s been used in traditional medicine for centuries and is recognized by Health Canada as a natural health product for soothing irritated mucous membranes.

Canadian pick: Traditional Medicinals Throat Coat (combines slippery elm with licorice root and marshmallow root). Available at health food stores and Well.ca.

5. Licorice root tea

Licorice root contains glycyrrhizin, which has antiviral and anti-inflammatory properties. A 2009 study found that gargling with licorice solution before surgery reduced postoperative sore throat by 50%. Drinking licorice root tea provides similar soothing effects.

Caution: Licorice root can raise blood pressure with excessive consumption. Limit to 1–2 cups per day and avoid if you have hypertension.

6. Green tea

Green tea is rich in catechins (EGCG), powerful antioxidants with antimicrobial properties. A 2016 meta-analysis found that regular green tea consumption was associated with lower rates of upper respiratory infection. Gargling with green tea may help reduce sore throat bacteria.

7. Turmeric tea

Curcumin, the active compound in turmeric, is one of the most studied anti-inflammatory compounds in nutrition. A warm turmeric tea (golden milk) can help reduce throat inflammation. Add black pepper to increase curcumin absorption by 2,000%.

8. Marshmallow root tea

Like slippery elm, marshmallow root contains mucilage that coats the throat. It’s gentle enough for children and pregnant women (consult your healthcare provider). Often combined with licorice root in blended teas like Throat Coat.

Key Takeaways

• Honey-lemon ginger tea has the strongest evidence for sore throat relief.
• Slippery elm and marshmallow root physically coat the throat with protective mucilage.
• Peppermint’s menthol provides natural numbing and decongestant effects.
• Avoid adding honey to boiling water — let the tea cool slightly first.
• If your sore throat lasts more than 7 days or is accompanied by high fever, see a doctor.

The Bottom Line

Warm tea is one of the simplest and most effective home remedies for a sore throat. Honey-lemon ginger is the most evidence-backed option, but chamomile, peppermint, and slippery elm all provide meaningful relief. Combine tea with rest, hydration, and over-the-counter pain relievers for best results.
