Best Tea for Nasal Congestion: 14 Warm Options for Comfort

Short answer: For most adults seeking a warm drink for general congestion comfort, peppermint, ginger, or food-grade eucalyptus tea are common options. None is proven to clear congestion.

Evidence checked 17 October 2026: A small 2008 trial found that a hot drink improved perceived nasal airflow and several cold symptoms, but it did not improve measured airflow. Evidence for specific brewed herbs remains limited. The European Medicines Agency supports eucalyptus leaf for cold-related cough through traditional use, not strong clinical trials. It does not recommend eucalyptus leaf preparations for children under 12.

This guide covers teas for general nasal and chest congestion. For facial pressure and poor sinus drainage, see our separate guide to the best teas for sinus congestion.

Nasal congestion can make sleeping, breathing, and concentration harder. Warm herbal tea can provide fluid and temporary symptom comfort.

A small 2008 study in Rhinology found that a hot fruit drink improved perceived nasal airflow and several cold symptoms. It did not improve the objective measure of nasal airflow. Tea can support comfort, but it does not replace treatment for the cause of congestion.

This guide compares 14 teas by flavour, caffeine, evidence limits, and safety.

14 Teas to Compare for Nasal Congestion Comfort

1. Peppermint Tea: Cooling Sensation

Peppermint tea contains menthol, which activates TRPM8 cold receptors and can create a sensation of easier airflow. That sensation does not prove that peppermint opens the nasal airway.

What the research says: Menthol can improve the sensation of nasal airflow. Controlled studies found no matching reduction in nasal resistance. These studies tested menthol, not peppermint tea as a congestion treatment.

How to brew it: Steep fresh or dried peppermint according to the pack directions. Cover the mug while it steeps. Let the drink cool to a comfortable temperature before sipping. Add honey if wanted, but never give honey to a child under 12 months.

How much: There is no proven congestion-relief dose. Follow the product directions.

Best fit: Adults who like mint and want a caffeine-free drink.

2. Eucalyptus Tea: A Strong-Aroma, Caffeine-Free Option

Eucalyptus tea contains eucalyptol (1,8-cineole). The EMA recognises eucalyptus leaf for traditional relief of cold-related cough, but this does not prove that the tea treats sinusitis.

What the research says: One trial found that cineole capsules improved symptoms of acute, non-purulent rhinosinusitis. Capsules are not the same as brewed eucalyptus tea. The EMA bases eucalyptus leaf use for cold-related cough on traditional use, not strong clinical trials.

How to brew it: Use a labelled, food-grade tea product and follow its directions. Let it cool before sipping. Never swallow eucalyptus essential oil.

How much: Follow the product directions. The EMA does not recommend eucalyptus leaf preparations for children under 12.

Best fit: Adults who can use eucalyptus safely and like its strong aroma.

3. Ginger Tea: A Warming, Caffeine-Free Option

Ginger tea is a warm, caffeine-free option. Research has mainly tested ginger extracts for other conditions, not brewed ginger tea for nasal congestion.

What the research says: Laboratory studies have examined ginger compounds and inflammation. They do not show that ginger tea opens a blocked nose or treats a respiratory infection.

How to brew it: Slice fresh ginger and simmer it in water for 10 to 15 minutes. Strain it, then add lemon or honey if wanted.

How much: There is no proven congestion-relief dose. Follow product directions and consider possible medicine interactions.

Best fit: Adults who want a warming, caffeine-free drink.

4. Chamomile Tea: A Caffeine-Free Evening Option

Chamomile tea (Matricaria chamomilla) is caffeine-free and can fit an evening routine. It has not been shown to reduce nasal swelling.

What the research says: Research has examined chamomile compounds and sleep. This does not establish chamomile tea as an antihistamine or decongestant. Avoid chamomile if it triggers your ragweed-family allergy.

How to brew it: Steep 2 teaspoons of dried chamomile flowers in just-boiled water for 5 to 7 minutes, covered. Add honey. Drink 30 minutes before bed.

How much: Follow the product directions.

Best fit: Adults who want a caffeine-free evening drink and can use chamomile safely.

5. Elderflower and Elderberry Tea: Traditional Cold Options

Elderflower (Sambucus nigra blossoms) has a history of traditional use for cold symptoms. Strong clinical evidence for brewed elderflower tea and allergy congestion is lacking.

Elderberry (Sambucus nigra fruit) supplements have been studied for upper respiratory symptoms. Those results do not prove that elderberry tea treats a cold or blocks a virus.

How to brew elderflower: Steep 2 teaspoons of dried elderflower blossoms in hot water for 10 minutes. Combines well with peppermint or nettle.

How to prepare elderberry: Use only a commercially prepared elderberry tea or fully cooked elderberries. Do not eat or steep raw, unripe, or uncooked elderberries, leaves, stems, or bark. Follow the product label.

Best fit: Adults who enjoy these flavours and want a warm drink during a cold.

6. Nettle Leaf Tea: A Traditional Allergy-Season Option

Stinging nettle (Urtica dioica) is often marketed for allergies. It is not a proven substitute for an antihistamine.

What the research says: A small trial tested freeze-dried nettle capsules, not tea. Its results do not show that nettle tea works like standard antihistamine medicine.

How to brew it: Steep 1 to 2 teaspoons of dried nettle leaves in boiling water for 10 to 15 minutes. The flavour is mild and earthy, similar to green tea. Add honey and lemon.

How much: There is no proven preventive dose for allergy congestion. Follow the product directions.

Best fit: Adults who like an earthy tea and have checked medicine interactions.

7. Thyme Tea: A Traditional Cough Remedy

Thyme tea has a history of traditional use for coughs. This does not mean that brewed thyme tea treats bronchitis or nasal congestion.

What the research says: One trial studied a standardised thyme-ivy liquid extract for acute bronchitis. It did not test homemade thyme tea or nasal congestion.

How to brew it: Steep fresh or dried thyme according to the product directions. Do not add ivy leaf to homemade tea.

Best fit: Adults who want a savoury, caffeine-free drink.

8. Turmeric Golden Milk: A Warming Spiced Drink

Turmeric contains curcumin, a compound studied in concentrated supplements. A kitchen drink contains a different and less predictable amount.

What the research says: A trial tested oral curcumin supplements in people with allergic rhinitis. It did not test turmeric tea or golden milk. Black pepper can change medicine absorption, so check with a pharmacist if you take regular medicines.

How to brew it: Simmer 1 teaspoon of turmeric powder, a generous pinch of black pepper, and half a teaspoon of ground ginger in 1 cup of milk (dairy, oat, or coconut) for 5 minutes. Add honey and a dash of cinnamon.

Best fit: Adults who want a warm, caffeine-free spiced drink.

9. Licorice Root Tea: Use With Extra Care

Licorice root (Glycyrrhiza glabra) tastes naturally sweet. It is not a proven treatment for a sinus infection or nasal congestion.

What the research says: Laboratory antiviral findings do not establish a clinical effect from tea. A trial of a specific licorice gargle before surgery does not show that tea treats an ordinary sore throat.

How to brew it: Use a labelled licorice tea and follow its directions. Product strength varies.

Safety: Licorice can raise blood pressure, lower potassium, and interact with medicines. Avoid it during pregnancy and if you have high blood pressure, heart disease, or kidney disease. Ask a pharmacist before use.

Best fit: Adults whom a pharmacist says can use licorice safely.

10. Marshmallow Root Tea: A Mild Option for Throat Comfort

Marshmallow root (Althaea officinalis) contains mucilage and is used in products for throat comfort.

What the research says: Some marshmallow preparations have been studied for dry cough. Evidence for homemade tea and congestion remains limited. It can affect the absorption of oral medicines, so separate them and ask a pharmacist.

How to brew it: For maximum mucilage, use a cold infusion: soak 1 tablespoon of dried marshmallow root in room-temperature water for 6 to 8 hours. For a quicker option, steep in just-boiled water for 10 minutes.

Best fit: Adults who want a mild drink for throat comfort.

11. Sage Tea: A Strong-Flavoured Throat Drink

Sage (Salvia officinalis) is used in some products for sore throat relief.

What the research says: A trial studied a measured sage spray, not brewed tea. The result does not show that sage tea treats an infection or clears congestion.

How to brew it: Steep 1 tablespoon of fresh sage leaves (or 1 teaspoon dried) in just-boiled water for 7 to 10 minutes. Add honey and lemon. For maximum throat contact, gargle with lukewarm sage tea before drinking it.

Best fit: Adults who enjoy sage and want a warm drink for throat comfort.

12. Echinacea Tea: Evidence Depends on the Product

Echinacea products vary by species, plant part, dose, and preparation. Results from one product do not apply to every tea.

What the research says: Reviews of echinacea products report mixed results for colds. They do not establish that ordinary echinacea tea prevents congestion or shortens a cold.

How to brew it: Use a labelled tea product and follow its directions. Ask a pharmacist before use if you have an autoimmune condition or take regular medicines.

Best fit: Adults who understand that evidence varies by product.

13. Green Tea: A Caffeinated Warm Option

Green tea contains caffeine and plant compounds called catechins. It is not a replacement for allergy medicine.

What the research says: Laboratory findings about catechins do not show that green tea relieves allergy congestion in people.

How to brew it: Follow the product directions. Cooler water may produce a less bitter drink.

How much: Consider the label's caffeine value and your total daily intake. Avoid it near bedtime if caffeine affects your sleep.

Best fit: Adults who want a caffeinated warm drink.

14. Oregano Tea: A Savoury Herbal Option

Oregano tea has a strong, savoury flavour. Laboratory antimicrobial findings do not show that oregano tea treats a respiratory infection.

How to brew it: Steep fresh or dried oregano leaves in hot water for 5 to 10 minutes. The flavour is strong and savoury, lemon juice and honey help significantly.

Best fit: Adults who enjoy the flavour and want a caffeine-free warm drink.

What Causes Nasal Congestion?

Nasal congestion is primarily caused by swollen blood vessels and inflamed tissue inside the nasal passages, not excess mucus, as most people assume. When the nasal mucosa becomes irritated by a virus, allergen, or environmental irritant, it swells and narrows the airway, trapping mucus behind it.

Common causes include:

• Viral infections (common cold, flu), the most frequent cause
• Allergies: Pollen, dust mites, pet dander, and mould can trigger histamine release.
• Sinusitis: Inflammation of the sinus lining can cause congestion.
• Environmental irritants: Dry air, pollution, smoke, and strong odours can irritate the nose.
• Structural issues: A deviated septum or nasal polyps can affect airflow.

The cause matters because tea does not treat every cause. Allergy medicine can help allergic rhinitis. A clinician can assess persistent, severe, or recurrent symptoms.

How Warm Tea May Help You Feel Better

Tea mainly supports comfort. Possible benefits include:

• Warmth. A warm drink can soothe the throat and improve perceived airflow.
• Fluid. Tea contributes to normal fluid intake.
• Comfort. A familiar drink can make rest easier.

Laboratory effects from isolated plant compounds do not prove that brewed tea kills an infection or opens the nose.

Safer Brewing Tips

• Keep a safe distance. Let the drink cool before you hold or sip it. Do not place your face over hot liquid.
• Follow the label. Use the stated amount and steeping time for a packaged herbal tea.
• Add honey if wanted. Honey may reduce cough symptoms for some people, but it does not treat congestion. Never give honey to a child under 12 months.
• Add lemon for taste. It does not make tea a decongestant.
• Drink warm, not scalding. Very hot liquid can burn or irritate tissue.

Complementary Remedies That Work Alongside Tea

These measures can support comfort or address congestion directly:

• Nasal irrigation with a neti pot. Use distilled, sterile, or previously boiled and cooled water. Follow device cleaning instructions.
• Gentle sinus self-massage. Evidence is limited. Stop if it causes pain, dizziness, or worse symptoms.
• Warm compresses. A warm cloth over the face may feel soothing. Check the temperature first.
• Using a humidifier. The US EPA recommends indoor humidity of 30% to 50%.
• Warm shower: Moist air from a shower can feel soothing. Avoid bowls of hot water and added essential oils because of burn and irritation risks.

Safety and Side Effects

While herbal teas are generally safe, these precautions apply:

• Licorice root: Avoid regular or high-dose use unless a pharmacist or clinician confirms it is suitable. Product strength varies. Licorice can raise blood pressure, lower potassium, and interact with medicines.
• Eucalyptus: Use only a labelled, food-grade product. Never swallow eucalyptus essential oil.
• Echinacea. Evidence varies by product; ask a clinician before use with an autoimmune condition.
• Elderberry: Use a commercially prepared product or fully cooked berries. Do not use raw, unripe, or uncooked berries, leaves, stems, or bark.
• Pregnancy: Ask a clinician before using herbal remedies during pregnancy.
• Medication interactions: Some herbs can interact with anticoagulants, blood pressure medicines, and diabetes medicines.
• Plant allergies: If you have an allergy to ragweed or related Asteraceae plants, use caution with chamomile. Avoid elderflower if it has caused a reaction before.
• Children: The EMA does not recommend eucalyptus leaf preparations for children under 12. Ask a clinician before giving herbal tea to a child. Never give honey to infants under 12 months.

When in doubt, consult your healthcare provider before starting any herbal tea regimen, especially if you take prescription medications.

When to See a Doctor

US guidance	UK NHS guidance
The CDC advises medical care when sinus symptoms last more than 10 days without improving, worsen after improving, or include fever for more than 3 to 4 days.	The NHS cold guidance advises seeing a GP when cold symptoms do not improve after 10 days. Its sinusitis guidance uses 3 weeks of self-care.

Get medical help sooner if:

• You develop a high fever above 39.4°C (103°F) lasting more than 3 days
• Symptoms improve then suddenly worsen (possible secondary bacterial infection)
• You experience difficulty breathing, chest pain, or severe headache
• You experience severe facial pain or swelling
• You have recurrent sinus infections (four or more per year)
• You have a weakened immune system or chronic health condition

These may indicate bacterial sinusitis, chronic sinusitis, bronchitis, pneumonia, or influenza, conditions that require medical treatment beyond herbal support.

Frequently Asked Questions

What is the best tea for nasal congestion?

Peppermint, ginger, and food-grade eucalyptus are common choices for adults. Menthol can create a cooling sensation that makes airflow feel easier, but it does not open the nasal airway. Evidence that a specific brewed tea treats congestion remains limited.

Does drinking tea actually help with a stuffy nose?

A warm drink may provide temporary comfort. The 2008 Rhinology study found better perceived airflow and improvement in several cold symptoms, but no improvement in measured nasal airflow.

How many cups of tea should I drink for nasal congestion?

There is no proven congestion-relief dose for herbal tea. Follow the product directions and consider your total fluid and caffeine intake. Ask a pharmacist about eucalyptus, licorice, medicines, pregnancy, or a chronic condition.

Can I mix different herbal teas together?

You can combine ordinary food teas if each ingredient is safe for you. Combining herbs has not been shown to treat congestion better. Check for medicine interactions and avoid complex blends during pregnancy unless a clinician approves them.

Is herbal tea better than decongestant medication?

No. Tea can support warmth, hydration, and comfort, but it does not replace treatment for allergies, infection, or another cause. Herbal products are not all safe for long-term use. Safety depends on the herb, dose, age, pregnancy, health conditions, and medicines.

What tea helps congestion and sore throat at the same time?

A warm honey, ginger, and lemon drink can soothe the throat and provide fluid. Honey can reduce cough symptoms for some people. Tea does not diagnose or treat a throat infection. Never give honey to a child under 12 months.

Should I drink hot or warm tea for nasal congestion?

Drink tea warm and comfortable, not scalding. Let it cool before sipping. A hot drink may improve comfort, but hotter liquid does not clear congestion more effectively.

Can I drink tea every day to prevent nasal congestion?

Tea can be part of your normal fluid intake, but no herbal tea has been proven to prevent nasal congestion. Long-term safety varies by herb. Ask a pharmacist if you take medicines or have a chronic condition.

Is this safe for children?

Ask a paediatrician or pharmacist before giving a child a herbal tea for symptoms. The EMA does not recommend eucalyptus leaf preparations for children under 12. Never give honey to an infant under 12 months.
