Several herbal teas can help calm a cough, and the best choice depends on whether your cough is dry and scratchy or wet and full of mucus. Warm liquids on their own loosen mucus and soothe irritated airways, but certain herbs add specific benefits on top of that, from relaxing the muscles in your throat to coating raw tissue with a protective layer.
Honey Tea for General Cough Relief
Adding honey to any tea is one of the simplest and most effective ways to ease a cough. A systematic review in BMJ Evidence-Based Medicine found that honey performed about as well as the active ingredient in most over-the-counter cough syrups at reducing both cough frequency and cough severity. That’s notable because honey has virtually no side effects for adults and children over one year old, while cough medicines can cause drowsiness and other issues.
Honey works partly as a demulcent, meaning it forms a soothing film over irritated throat tissue. It also has mild antimicrobial properties. Stir one to two teaspoons into any warm tea. The type of honey doesn’t matter much, though darker varieties like buckwheat honey tend to have higher antioxidant content. One critical safety note: never give honey to a baby under one year old, as it can contain spores that cause infant botulism.
Peppermint Tea for Congestion and Dry Cough
Peppermint tea is especially useful when your cough comes with a stuffy nose or tight chest. The menthol in peppermint activates cold-sensing receptors in your airways, which creates that familiar cooling sensation and helps open up your breathing passages. This same mechanism also appears to suppress the cough reflex itself. The effect works through nerve pathways in the face and throat rather than by directly acting on your lungs, which is why even inhaling the steam from a cup of peppermint tea can bring noticeable relief.
For a dry, tickly cough that keeps you up at night, peppermint tea is a strong choice because it calms the urge to cough without needing to move mucus. Steep the leaves for at least 10 to 15 minutes with a lid on the cup to keep the volatile menthol compounds from escaping with the steam.
Thyme Tea for Chest Coughs
Thyme is one of the most well-studied herbs for respiratory complaints, and it’s particularly good for productive coughs where you’re trying to clear mucus. The key compound, thymol, has a direct antispasmodic effect on the trachea, relaxing the muscles that tighten during a coughing fit. Research published in Planta Medica showed that thymol relaxes airway tissue in a dose-dependent way and also stimulates the tiny hair-like structures (cilia) that sweep mucus up and out of your lungs.
Thyme also activates beta-2 receptors, the same targets that asthma inhalers work on, though at a much milder level. To make thyme tea, steep one to two teaspoons of dried thyme in boiling water for 10 to 15 minutes. The taste is savory and herbaceous. Adding honey and a squeeze of lemon makes it more pleasant to drink.
Marshmallow Root and Slippery Elm for a Raw Throat
If your cough has left your throat feeling stripped and painful, teas made from marshmallow root or slippery elm are worth trying. Both contain high concentrations of mucilage, a group of complex sugars that dissolve in water and form a thick, gel-like coating. When you drink the tea, this gel lines your throat and creates a physical barrier between irritated tissue and the dry air or stomach acid that keeps triggering your cough reflex. Memorial Sloan Kettering Cancer Center notes that slippery elm’s mucilage is specifically responsible for its cough-suppressing and tissue-soothing properties.
These teas are best for dry, hacking coughs rather than wet, mucus-producing ones. Marshmallow root and slippery elm are both roots and bark, so they need a longer preparation than leaf teas. Simmer them in water on low heat for 30 to 60 minutes with a lid on. The resulting tea will have a slightly thick, silky texture, which is exactly the mucilage doing its job.
Licorice Root Tea as an Expectorant
Licorice root is a good option when your cough feels “stuck,” with thick mucus you can’t quite clear. Animal studies have found that compounds in licorice can reduce cough frequency by 30% to 78% and act as expectorants, helping to thin and loosen mucus so it’s easier to cough up. The tea has a naturally sweet flavor that pairs well with other herbs.
Licorice root does come with a real caution, though. Its active compound, glycyrrhizin, can raise blood pressure and lower potassium levels if consumed in large amounts. European and World Health Organization guidelines set the safe limit at 100 milligrams of glycyrrhizin per day for most adults, and some people are sensitive to even lower doses. One or two cups a day is generally fine for short-term use, but if you have high blood pressure or take heart medications, skip this one or look for “deglycyrrhizinated” versions.
Ginger Tea for Inflamed Airways
Ginger has strong anti-inflammatory and antioxidant properties that help calm swollen, irritated airways. This makes it a versatile choice for both dry and wet coughs, particularly when the cough is part of a cold or upper respiratory infection. The warming sensation from ginger’s active compounds also increases circulation in the throat, which can speed healing of damaged tissue.
Fresh ginger is more potent than dried. Slice a one-inch piece of fresh ginger root, simmer it in water for 10 to 15 minutes, and strain. Combining ginger with honey and lemon is a classic cold-weather remedy for good reason: the ginger reduces inflammation, the honey coats the throat, and the lemon adds vitamin C along with a pleasant tartness that cuts through congestion.
Matching the Tea to Your Cough
A dry, tickly cough that produces no mucus responds best to demulcent and soothing teas. Marshmallow root, slippery elm, and peppermint are your best bets here, along with generous honey. The goal is to coat and calm irritated tissue so the cough reflex stops firing.
A wet, productive cough with mucus benefits more from thyme and licorice root, which help relax airway muscles and thin out mucus so you can clear it more effectively. Ginger works well for both types because it targets the underlying inflammation rather than the mucus itself.
Getting the Most Out of Herbal Tea
How you brew matters. Leaf and flower teas like peppermint and thyme should steep in boiling water for 15 to 20 minutes with a cover to trap volatile oils. Root teas like marshmallow root, slippery elm, licorice, and ginger need to simmer on low heat for 30 to 60 minutes to fully extract their active compounds. Using boiling water and steeping for only five minutes, the way you might prepare a casual cup, leaves most of the medicinal value still locked in the plant material.
Drinking three to four cups spread throughout the day is more effective than one large mug. The soothing and coating effects of these teas are temporary, lasting roughly an hour or two, so consistent intake keeps your throat protected. Drinking a cup shortly before bed can be especially helpful for nighttime coughs that disrupt sleep.
