Asthma is a chronic disorder that affects the lining of your airways, which become inflamed and narrow, resulting in symptoms like shortness of breath, wheezing, coughing, and chest tightness (1).

Although there are many conventional treatments for asthma, some herbal teas may relieve symptoms.

Here are 7 teas that may provide asthma relief.

Ginger tea is made by boiling the roots of the ginger plant (Zingiber officinale).

This powerful spice is loaded with nutrients and bioactive compounds. It’s associated with benefits like reduced inflammation, nausea relief, and lower blood sugar levels (2, 3, 4).

Plus, research suggests that ginger may help relieve asthma symptoms.

Test-tube studies using human cells indicate that ginger compounds, such as gingerols and shogaols, may alleviate asthma symptoms by reducing airway inflammation (5, 6, 7, 8).

In a 2-month study, 92 people with asthma took either 450 mg of ginger extract or a placebo daily. Notably, 20% of those in the ginger group experienced wheezing relief, and 52% experienced chest tightness relief (9).

Alternatively, you can make ginger tea at home. Simply grate a small knob of peeled ginger, steep it in 1 cup (240 mL) of boiling water for 10–20 minutes depending on your desired strength, then strain out the ginger.

You can enjoy ginger tea as is or with a dash of lemon, honey, or cinnamon.

Summary

Ginger contains gingerols and shogaols, which are compounds that may provide temporary relief from asthma symptoms.

Green tea is a popular beverage derived from the leaves of the Camellia sinensis plant.

It’s packed with nutrients, plant compounds, and antioxidants, which are tied to weight loss, as well as a lower risk of type 2 diabetes, heart disease, and certain cancers (10, 11, 12, 13).

In addition, research suggests that green tea may relieve asthma symptoms.

For starters, animal studies show that green tea antioxidants may help reduce inflammation in the lungs — a common feature of asthma (14, 15).

In addition, a study in over 1,000 people found that those who drank at least two 8-ounce (240-mL) cups of green tea had significantly better lung function than those who drank none (16).

Lastly, green tea is a source of caffeine, which may help relax your airways for up to 4 hours and provide temporary relief from asthma symptoms (17).

You can purchase green tea loose leaf or in tea bags.

Summary

Green tea is packed with antioxidants, which may help reduce asthma-related inflammation. It’s also a source of caffeine, which may temporarily relax your airways.

Like green tea, black tea comes from the Camellia sinensis plant. However, it’s exposed to air for oxidation, which causes the leaves to turn dark brown, intensifying the flavor. It’s often blended with other ingredients to make teas like English breakfast or Earl Grey.

Similarly to green tea, black tea contains caffeine, which may help relax your airways and modestly improve lung function. This may provide temporary relief from asthma symptoms (17).

Its other potential benefits include a lower risk of heart disease and type 2 diabetes (18, 19).

Summary

Black tea provides caffeine, a stimulant that may modestly improve lung function and provide temporary relief from asthma symptoms.

Eucalyptus tea is made from the leaves of the eucalyptus tree, which is packed with powerful antioxidants and plant compounds like eucalyptol.

Notably, eucalyptol may help treat asthma symptoms.

Research suggests that this compound may reduce inflammation, decrease mucus production, and expand your bronchioles — the passageways inside your lungs (20, 21).

In a 12-week study, 32 people with bronchial asthma were given either 600 mg of eucalyptol or a placebo daily. Those who received eucalyptol required 36% less medication to manage asthma symptoms, compared with those in the control group, who needed 7% less (22).

Alternatively, you can make your own at home using dried eucalyptus leaves. Simply steep the dried leaves in 1 cup (240 mL) of boiling water for up to 10 minutes and use a strainer or cheesecloth to remove the leaves before drinking.

Summary

Eucalyptus tea contains eucalyptol, a compound that may help reduce certain asthma symptoms.

Licorice tea is made from the root of the licorice plant (Glycyrrhiza glabra) and has a distinctly sweet but slightly bitter flavor.

In traditional medicine, licorice root has long been used to treat various conditions, including asthma.

Animal studies note that extract of the licorice compound glycyrrhizin relieves symptoms of asthma, especially when combined with conventional asthma treatments like salbutamol (albuterol) (23, 24, 25).

Although human research has shown similar results, more long-term research is needed (26).

Keep in mind that large amounts of licorice root may lead to dangerous side effects. It’s best to limit your tea intake to 1 cup (240 mL) per day and speak to your healthcare provider if you have any medical conditions.

Summary

Licorice tea is made from licorice root, the extract of which may relieve asthma symptoms — especially when combined with conventional treatments.

Mullein tea is a rich and aromatic infusion made from the leaves of the common mullein (Verbasscum thapus), which is native to Europe, Asia, and Africa.

It has been used in traditional medicine for thousands of years as a remedy for respiratory conditions, such as bronchitis, mucus buildup (catarrh), and asthma.

Animal and human studies suggest that mullein may help treat asthma symptoms like coughing, wheezing, and shortness of breath by reducing inflammation, which helps relax the muscles in your respiratory tract. Still, more research is needed (27).

Mullein tea is available in prepackaged tea bags and or dried leaf form.

If you’d like to make mullein tea with dried leaves, simply add a small amount to 1 cup (240 mL) of boiling water and steep for 15–30 minutes. Use a strainer or cheesecloth to remove the leaves to avoid throat irritation.

Summary

Mullein may relieve asthma symptoms by relaxing muscles in your respiratory tract. Keep in mind that more human studies are needed.
