Several herbal teas can help calm a dry cough by soothing irritated throat tissue, relaxing airway muscles, or suppressing the cough reflex itself. The most effective options include honey tea, marshmallow root tea, ginger tea, licorice root tea, thyme tea, and peppermint tea. Each works through a slightly different mechanism, so the best choice depends on what’s driving your cough and when it’s bothering you most.
Honey Tea
Honey is one of the most studied natural cough remedies, and the evidence is surprisingly strong. A 2018 review found honey was as effective as, or more effective than, over-the-counter cough medications at relieving cough symptoms. It’s particularly good for nighttime coughs: studies in children show it reduces coughing frequency and improves sleep. A separate trial comparing a ginger-honey mixture to dextromethorphan (the active ingredient in most OTC cough syrups) found that the honey combination led to faster recovery without the drowsiness that comes with the medication.
Honey tea is also the simplest option. Stir one to two teaspoons of honey into any hot tea you enjoy. The honey coats the back of the throat, forming a protective layer over irritated tissue. One important note: honey should never be given to children under one year old due to the risk of botulism.
Marshmallow Root Tea
Marshmallow root is one of the best options specifically for a dry, irritative cough because of how it physically interacts with your throat. The root contains complex polysaccharides that, when steeped in water, form a thick, gel-like substance called mucilage. This mucilage coats the irritated lining of your mouth and throat, creating a protective film that shields the tissue from whatever is triggering your cough reflex. It essentially reinforces the natural mucus layer your body already produces.
Beyond this coating effect, marshmallow root also appears to stimulate cell metabolism in the throat lining, helping damaged tissue recover faster. A 2020 study found it can decrease swelling in mucous membranes while relieving cough, and a 2017 study showed it may also inhibit bacterial growth.
Preparation matters here. Unlike most herbal teas, marshmallow root works best when steeped in room-temperature or cool water rather than boiling water. Cold steeping extracts more of the mucilage that gives this tea its throat-coating properties. Let it sit for at least 30 minutes, or ideally a few hours, before drinking.
Ginger Tea
Ginger tackles a dry cough from a different angle: it reduces the airway inflammation that keeps you coughing. The active compounds in ginger (primarily gingerols and shogaols) have strong anti-inflammatory and antioxidant properties. These compounds work by inhibiting a key enzyme that controls muscle contraction in the airways, which relaxes the smooth muscle tissue and reduces the hypersensitivity that triggers coughing fits. Animal studies show ginger extract significantly inhibits cough, and research on airway smooth muscle has confirmed its bronchorelaxant properties.
Ginger also helps thin mucus and clear it from the lungs, which can be useful if your dry cough is on the verge of becoming productive. To make ginger tea, slice fresh ginger root into thin pieces and steep in boiling water for 10 to 15 minutes. The longer you steep, the stronger the flavor and the more active compounds you’ll extract. Adding honey gives you a combination that covers both throat coating and airway relaxation.
Thyme Tea
Thyme is a lesser-known cough remedy, but it has a long history in European herbal medicine for respiratory complaints. The volatile oils in thyme, particularly thymol and carvacrol, work together with flavonoids and saponins to deliver three effects at once: they suppress the cough reflex (antitussive), relax spasms in the airways (antispasmodic), and help thin mucus so it’s easier to clear (expectorant). This combination makes thyme tea useful for the kind of dry cough that comes with a tight, spasm-like feeling in the chest or throat.
To make thyme tea, steep one to two teaspoons of dried thyme (or a few sprigs of fresh thyme) in boiling water for five minutes. Strain and drink. The flavor is savory rather than sweet, so honey is a natural pairing that also adds its own cough-relieving benefits.
Licorice Root Tea
Licorice root contains over 300 flavonoids with antioxidant and anti-inflammatory properties. In animal studies, licorice compounds reduced cough frequency by 30% to 78%, and they also act as expectorants to help loosen mucus. Licorice may also help fight the underlying infection, as research suggests it can inhibit the growth of several species of bacteria, fungi, and some viruses.
However, licorice root comes with real safety concerns that the other teas on this list don’t. The active compound glycyrrhizin can cause potassium levels to drop, leading to high blood pressure, abnormal heart rhythms, swelling, and in severe cases, heart failure. People who already have high blood pressure, older adults, and women are more sensitive to these effects. If you take medications that affect potassium levels or blood pressure, avoid licorice root tea entirely. For everyone else, keep it to short-term use, no more than a few days in a row.
Peppermint Tea and Green Tea
Peppermint tea contains menthol, which acts as a mild local anesthetic on the throat. It numbs the receptors that trigger the cough reflex, providing temporary relief. Menthol also creates that familiar cooling sensation that makes breathing feel easier when your airways are irritated. Peppermint tea is a solid choice when your dry cough is accompanied by throat soreness or a scratchy, raw feeling.
Green tea is a more modest option. One study found that gargling with green tea reduced coughing after surgery, though it didn’t help with hoarseness. Green tea’s benefit likely comes from its high antioxidant content, which can reduce inflammation in the throat. It’s not the strongest choice for cough relief on its own, but it makes a good base for adding honey.
How to Get the Most From Your Tea
For leaf-based and herbal teas, use boiling water (212°F) and steep for a full five minutes to extract the maximum amount of active compounds. Green tea is the exception: use cooler water around 175°F and steep for one to three minutes to avoid bitterness. Root teas like ginger benefit from longer steeping times of 10 to 15 minutes because the tough root fibers take longer to release their compounds. Marshmallow root, as mentioned, works best cold-steeped.
The steam itself also helps. Breathing in warm, moist air loosens irritated airways and adds moisture to dry throat tissue. Cup your hands around the mug and breathe in the steam before sipping. For nighttime coughs, drink your tea about 30 minutes before bed. A honey-based tea is the strongest choice for overnight relief since the evidence for nighttime cough reduction is most robust with honey.
Combining ingredients is perfectly fine and often more effective than any single tea. A ginger-honey tea, for example, pairs anti-inflammatory airway relaxation with throat coating. Thyme with honey covers cough suppression, airway relaxation, and mucus thinning in one cup. Experiment to find the combination that works best for your particular cough.
