Why Tea Helps When You Have a Cough
Warm beverages, such as tea, have long been used as a natural remedy for coughs and colds. The benefits are multi-faceted and work together to provide relief.
- Hydration: Staying hydrated is crucial when sick. Warm tea helps prevent dehydration and keeps your respiratory tract moist, which soothes irritation and calms the cough reflex.
- Soothing Warmth: The warmth of a hot cup of tea can provide immediate relief to a raw or sore throat caused by persistent coughing.
- Expectorant Effect: Warm liquids help to loosen and thin mucus, making it easier to cough up and clear your airways.
- Anti-inflammatory Properties: Many herbs and teas contain natural compounds with anti-inflammatory effects that can reduce swelling in the airways and throat, easing discomfort.
The Best Teas for Soothing a Cough
Honey and Lemon Tea
This classic combination is a popular natural remedy for a reason. Honey is a natural cough suppressant and helps soothe the throat by coating its lining, which can reduce the irritation that triggers coughing. A 2018 review found that honey can be as effective as some over-the-counter cough medications for relieving nighttime coughs in children over one year old. Lemon adds a dose of immune-boosting vitamin C and helps to thin mucus.
To prepare a basic honey and lemon infusion:
- Squeeze half a fresh lemon into a mug.
- Add 1 to 2 teaspoons of raw honey, ensuring it is not for a child under one year old.
- Pour in a cup of hot water (not boiling) and stir until dissolved. You can add a slice of fresh ginger for extra potency and anti-inflammatory benefits.
Ginger Tea
Ginger is a potent spice known for its strong anti-inflammatory and antioxidant properties, which can help soothe irritated airways. It also acts as a stimulating expectorant, helping to thin and clear mucus from the lungs. This makes it particularly effective for wet or congested coughs. Animal studies have shown ginger extract can significantly inhibit coughing fits.
Peppermint Tea
Peppermint tea's invigorating aroma comes from menthol, a natural decongestant. Menthol helps open up nasal passages and thins mucus, making breathing easier. It also has antimicrobial and pain-relieving properties, beneficial during a cold. The cooling sensation is especially soothing for an irritated throat.
Licorice Root Tea
Licorice root has been used in traditional medicine for centuries due to its antiviral and antimicrobial benefits. It also acts as an expectorant, helping to loosen mucus. Its soothing mucilage content can help calm dry, irritated coughs. However, licorice root can raise blood pressure in large quantities and should be used with caution. Pregnant people should avoid consuming it.
Thyme Tea
Often used as a culinary herb, thyme can be steeped into a tea to provide significant coughing relief. Studies have shown that thyme, particularly when combined with ivy, can help reduce the severity and frequency of coughing fits. Thyme tea's compounds, such as thymol and carvacrol, offer antimicrobial and expectorant properties that support respiratory health.
Chamomile Tea
Known for its calming effects, chamomile tea can help reduce inflammation and ease throat discomfort associated with coughing. Its relaxing properties can also aid in getting better sleep, which is crucial for recovery. Chamomile's flavonoids also provide antioxidant benefits.
Marshmallow Root Tea
This herbal root is rich in mucilage, a gummy substance that coats the throat and mucous membranes, providing a protective film against irritation. This makes it particularly effective for soothing a dry, scratchy cough. Unlike other teas, marshmallow root tea should be prepared by steeping in cool or room-temperature water to maximize its mucilage content.
Green Tea
Packed with antioxidants, green tea helps reduce inflammation and fight off infections. While it does contain caffeine, it can be beneficial for overall immune support and has been shown in one study to reduce coughing in post-surgical patients.
Elderberry Tea
Elderberry has been used for centuries to ease cold and flu symptoms. It is rich in antioxidants and anti-inflammatory properties that can help bolster the immune system and potentially shorten the duration of an illness causing a cough.

Choosing and Brewing Your Tea
To select the most beneficial tea for your ailment, consider the specific type of cough you have. For a dry, irritated cough, options high in mucilage like marshmallow root or licorice root might be most effective. For a productive, wet cough with congestion, ginger or peppermint can help thin mucus and clear airways. For general soothing and immune support, a honey-lemon or green tea is a great option.
General Brewing Tips for Maximum Benefit:
- Use fresh, high-quality ingredients when possible to ensure potency.
- Adjust steeping time to taste; typically, 5-10 minutes is sufficient for leaves and flowers.
- For roots and barks like licorice or ginger, simmering them for 10-15 minutes is more effective for extracting medicinal compounds.
- If adding honey, wait for the water to cool slightly before mixing it in to preserve its beneficial properties.
- Breathe in the steam from the hot tea for added congestion relief.
Important Considerations
Always consult a healthcare professional before using herbal teas, especially if you are pregnant, breastfeeding, have a pre-existing medical condition, or take other medications. As noted in the table, some herbs, such as licorice root, marshmallow root, and ginger, can interact with certain medications or cause side effects if consumed in large quantities. If your cough persists for more than two weeks, worsens, or is accompanied by fever, chest pain, or shortness of breath, it is crucial to seek medical advice.
Conclusion: Choosing the Right Tea for Your Cough

By selecting the right tea and preparing it correctly, you can harness nature's remedies to feel better sooner.
