Several herbal teas can genuinely help with a cough and sore throat, and the best choice depends on your specific symptoms. Ginger tea reduces inflammation in irritated airways. Marshmallow root and slippery elm coat the throat with a protective film. Peppermint tea opens up your breathing. And adding honey to any of them works about as well as a standard over-the-counter cough suppressant. Here’s what each one does and when to reach for it.
Honey: The Most Effective Add-In
Before getting into specific teas, honey deserves its own mention because stirring it into any warm tea is one of the most effective things you can do for a cough. A clinical trial published by the American Academy of Family Physicians compared buckwheat honey to dextromethorphan (the active ingredient in most OTC cough syrups) in 105 children with upper respiratory infections. Honey performed equally well at reducing nighttime coughing and improving sleep, and it significantly outperformed no treatment at all. Honey also has mild antibacterial properties, making it a useful addition regardless of which tea you choose.
A spoonful stirred into warm tea is the simplest delivery method. One important restriction: never give honey to a baby under one year old. Honey can contain bacterial spores that infant digestive systems can’t handle, potentially causing a serious condition called infant botulism. After age one, children develop the gut bacteria needed to neutralize those spores.
Ginger Tea for Inflammation
Ginger is one of the better-studied options for throat and airway irritation. Its active compounds work as natural anti-inflammatories, reducing the production of proteins that drive swelling and pain in irritated tissue. Ginger also lowers levels of several chemical messengers that your immune system releases during infection, the same ones responsible for that raw, inflamed feeling in your throat. On top of that, ginger acts as an antioxidant, helping replenish protective enzymes and reducing cellular damage from the immune response itself.
To make ginger tea, slice about an inch of fresh ginger root and steep it in boiling water for 10 to 15 minutes. The longer it steeps, the stronger the flavor and the more active compounds you extract. Adding honey and a squeeze of lemon rounds out the effect: the honey suppresses the cough, and lemon’s vitamin C and citric acid can help cut through mucus buildup.
Marshmallow Root for a Raw, Scratchy Throat
If your throat feels dry, scratchy, or like it’s been rubbed with sandpaper, marshmallow root tea is worth seeking out. The root is rich in mucilage, a type of complex carbohydrate that turns thick and gel-like when mixed with water. When you drink it as a tea, this mucilage coats the lining of your throat with a slippery protective layer, physically shielding irritated tissue from further irritation every time you swallow, talk, or cough. Marshmallow root is also mildly anti-inflammatory.
You’ll find marshmallow root in many “throat coat” tea blends at grocery stores and pharmacies. For the strongest effect, steep it in room temperature or warm water rather than boiling, since excessive heat can break down some of the mucilage before it reaches your throat.
Slippery Elm for Persistent Coughing
Slippery elm bark works through the same basic mechanism as marshmallow root. It contains its own mucilage that coats the throat when dissolved in water, forming a soothing film over inflamed tissue. This coating effect is well enough established that slippery elm is an ingredient in many commercial throat lozenges. As a tea, it has a mild, slightly sweet flavor. You can find slippery elm tea bags in most health food stores, or buy the powdered bark and stir about a tablespoon into hot water. It thickens as it sits, so drink it while it’s warm.
Peppermint Tea for Congestion
Peppermint tea is the best pick when your cough comes with a stuffy nose or chest congestion. Menthol, the compound that gives peppermint its cooling sensation, improves the perception of airflow through your nasal passages. It doesn’t physically widen your airways the way a decongestant medication does, but it triggers cold-sensitive receptors in your nose and throat that make breathing feel noticeably easier.
The steam from a hot cup of peppermint tea adds to this effect. Warm liquids have been shown to temporarily improve symptoms of sinus congestion, including runny nose, coughing, and sore throat. Peppermint is also a good option if you find some of the other herbal teas too unfamiliar in flavor, since it’s widely available and most people already know they like it.
Licorice Root Tea for Swelling and Pain
Licorice root has a long history of use for throat complaints, and the mechanism is straightforward: its active compounds decrease swelling and suppress cough. Licorice root tea has a naturally sweet flavor, which makes it palatable on its own or blended with other herbs. Many “throat coat” blends combine it with marshmallow root and slippery elm for a layered effect.
However, licorice root comes with more cautions than other options on this list. Consuming it regularly or in large amounts can raise blood pressure and lower potassium levels. People with heart disease, kidney disease, or high blood pressure should avoid it. It can also mimic estrogen in the body, so it’s not recommended for anyone with hormone-sensitive conditions like certain cancers, endometriosis, or uterine fibroids. Pregnant women should not use it. For an occasional cup during a cold, most healthy adults are fine, but it’s not one to drink daily for weeks.
How to Get the Most From Your Tea
Whichever tea you choose, a few practical tips make a real difference. Drink it warm, not scalding. Very hot liquids can actually irritate already-inflamed tissue and potentially damage the delicate lining of your throat and airways. Warm is soothing; hot is not.
Add honey and lemon as a default combination. The honey suppresses coughing (with clinical evidence behind it), while lemon helps break through mucus and provides vitamin C. Together with any of the teas above, they form a more complete approach than any single ingredient alone.
Frequency matters more than volume. Sipping tea throughout the day keeps your throat coated and hydrated. A single cup in the morning won’t carry you through an afternoon of coughing. Three to five cups spread across the day is a reasonable target when you’re actively sick. Staying well-hydrated in general helps thin mucus and makes coughs more productive, so the fluid intake from tea itself is part of the benefit.
If you’re unsure where to start, a ginger tea with honey and lemon is the most versatile choice for a standard cold with both cough and sore throat. For a throat that feels raw and dry, switch to or add marshmallow root or slippery elm. For heavy congestion, reach for peppermint. And if you want to cover multiple bases, look for a pre-blended “throat coat” tea that combines several of these ingredients in one bag.
