Health Benefits of Mullein Tea

1. May Treat Respiratory Conditions

Mullein tea may help combat several respiratory ailments like cold, cough, and bronchitis. It can also offer relief from sore throat. The antibacterial properties of mullein may help treat inflammation and infection in the respiratory tract (1).

Mullein tea may help relieve asthma, which causes swelling in the airways and results in shortness of breath, wheezing, and coughing (2), (3). Mullein is said to possess expectorant, mucolytic, and demulcent properties that promote sputum secretion. This reduces cough, helps with the clearance of mucus from the airways, and relieves irritation of the mucous membranes (1).

Its flowers and leaves are used for treating a wide range of respiratory ailments, such as chills and flu, tuberculosis, bronchitis, pneumonia, asthma, tonsillitis, and tracheitis (4). However, more human studies are needed to prove these claims.

2. May Help Fight Viral Infections

Mullein tea is said to have antiviral activity and may help fight certain viral infections. In one study, mullein extracts showed antiviral activity against influenza virus (5). Another study conducted by the National University of Rio Cuarto found that the methanolic extracts of mullein may fight against the pseudorabies virus (6).

Alcoholic extracts of mullein were found to exhibit antiviral activity against pseudorabies virus (7). However, more long-term research is required to understand this benefit of mullein in humans.

3. Exhibits Antibacterial Properties

Mullein tea may exhibit antibacterial properties. A study conducted by the Islamic Azad University found that the ethanolic extract of mullein has antimicrobial and antioxidant properties. They act against certain bacterial strains, including Bacillus cereus (8).

Since ancient times, mullein has been used as an effective remedy to treat infectious diseases. Another study conducted by the Jundishapur University of Medical Sciences found that aqueous-alcoholic extracts of mullein possess some antibacterial effects (9).

4. May Relieve Issues With Sleep

Insomnia is a growing issue among men and women belonging to various age groups. Mullein tea may act as a natural sedative and help relieve sleeping problems (1).

The roots, leaves, and flowers of the mullein plant also possess sedative properties that help treat issues with sleep (10). More research is needed to understand mechanism of mullein tea in this regard.

5. May Aid Tuberculosis Treatment

Several studies state mullein to be a potential treatment option for tuberculosis. It could also help in the treatment of skin disorders and leprosy (11), (1).

However, more studies are needed to establish its potential as a treatment for tuberculosis.

6. May Improve Digestive Health

The consumption of mullein tea may help improve a number of digestive issues. It may provide relief from diarrhea and constipation (4), (12). It may also help cope with bowel related problems and help your body eliminate toxins easily.

7. May Soothe Skin Conditions

Mullein tea possesses anti-inflammatory properties that help treat skin problems. You can also use the oil to get relief from a variety of skin infections.

The tea may help heal blisters, wounds, and small cuts. The oil made from the mullein flowers can be applied externally on affected areas in the case of eczema and other inflammatory skin conditions (13). You may also topically apply mullein leaf extract on sores and wounds. Anecdotal evidence suggests that it can have a calming effect on the skin.

8. May Help Relieve Joint Pains And Muscle Spasms

Mullein tea’s anti-inflammatory properties may make it ideal to use it in treating joint pain (12). This herb may reduce inflammation. The antispasmodic effect of this herbal tea may help treat muscle spasms (14).

9. May Treat Thyroid Issues

Anecdotal evidence suggests that intake of mullein tea may improve thyroid-related problems. The tea may help treat an overactive thyroid gland (a condition called hyperthyroidism). A formula created by a noted doctor had mullein as one of its constituents. This formula was specifically targeted to treat thyroid issues (15). However, research in this aspect is limited. We need more studies to substantiate the therapeutic effects of mullein tea for thyroid issues.

What Are The Side Effects Of Mullein Tea?

Mullein plant tea does not have any documented potential risks on humans. The few reactions that may occur in some users are not fatal. Studies do not show any side effects on pregnant women as well. However, anecdotal evidence suggests expectant mothers avoid prolonged use of any compound that contains mullein. Other potential adverse effects mullein tea may cause include the following:

  • Skin Irritation

Some individuals have reported skin irritation after using mullein extracts in tea and other forms. Avoiding the extract may cure the skin irritation in such people.

  • Breathing Issues

Mullein leaves are fluffy and hairy. If they get stuck in the throat, they may cause breathing issues. This usually happens when you make the tea and do not strain the mixture well. In some isolated cases, people taking the tea have reported difficulty inhaling and inflammation of their chest walls. However, medical intervention is not required in most instances.

The side effects are not backed by research. Hence, if you experience any of them, visit your doctor right away.
