The Amazing Benefits of Mullein Tea

Mullein tea is made from the rich, aromatic leaves of the common mullein (Verbascum thapsus), native to Asia, Africa, and Europe. Mullein tea has a rich aromatic herbal taste that keeps one refreshed, and it is also caffeine-free. It is used in traditional medicine as a sedative and an astringent and can cure a cold and cough. 

It is a flavorful beverage used to treat a wide range of ailments from asthma and colds to chronic coughs. For centuries, mullein tea has been linked and used to treat several diseases. Mullein tea extract may have antibacterial and antiviral properties and may be used to treat respiratory conditions. However, further studies and human researches are needed for certainty and clarity.

Mullein tea may help treat tuberculosis, sleeping problems, viral and bacterial infections, and respiratory conditions as it is said to possess antiviral, antioxidant, antibacterial, and other beneficial properties. 

This article studies the vast uses, how it can benefit you, and the potential side effects of mullein tea - and other information. Let's take a look at the top five benefits of mullein tea.

Top Five Benefits of Mullein Tea

Over the years, mullein tea has been connected to various potential health benefits. 

1. May help combat viral infections

Some clinical studies suggest that mullein tea may have antiviral properties to help fight viral infections. After analyzing various species of medicinal herbs, the mullein extract was found effective against the influenza virus. 

Other tests also show that the mullein plant extract may also be used to fight pseudorabies (herpes virus). However, human research is essential. 

2. May treat respiratory conditions

For centuries, mullein tea and extract have been used to treat respiratory conditions. It may relieve asthma and symptoms that come as a result of the swelling of the airway. It may also treat shortness of breath, wheezing, and coughing. Research on animals and humans has suggested that mullein tea works perfectly in relaxing the respiratory tract muscles and reducing infection and inflammation in the respiratory tract. 

Mullein plant's leaves and flowers possess mucolytic, demulcent, and expectorant properties that boost sputum's secretion. This reduces cough and relieves irritation in the mucous membrane, and helps clear the airways of mucus.

Traditionally, mullein has been used to treat respiratory ailments such as pneumonia, tracheitis, tonsillitis, bronchitis, chills, and flu, and tuberculosis as our ancestors noticed that this herb seems to affect and in many cases improve the lung area. This has been reported in many studies. Today in modern times we are still in the process of study to more accurately prove or disprove these effects on the lungs – although anecdotal evidence is abundant it’s best not to always rely on it.

3. Possesses antibacterial properties

Mullein tea possesses antibacterial properties to help you fight and treat bacterial infections. A test-tube study found that mullein extracts repressed several bacteria strains, especially Bacillus cereus, found in food and soil. 
Another test conducted found mullein extract to inhibit the growth and spread of certain types of infection-causing bacteria, the likes of Streptococcus pyogenes, and E. coli. 

Although there is a limited amount of study on human research, a survey conducted with 180 children showed that the mullein herb might treat ear infections. This is because bacteria are often the cause of ear infection and indicates that not only mullein would be effective in this case but other antibacterial herbs too. 

The three-day study used ear drops containing mullein extract alongside other herbal extracts three times daily. The combination reduced ear pain by a significant 93%. However, the mullein extract's effect in the ear drops isn't specific as it was used in combination with other herbal extracts. This is why additional human research is necessary.    

4. May aid tuberculosis treatment 

Various research and studies has shown that mullein tea might be a potential treatment choice for tuberculosis. It could also help in treating leprosy and skin disorders. 
Despite these studies, several more are needed to prove that mullein tea is a treatment for tuberculosis.

5. May relieve sleep issues and disorders

Mullein tea has the properties to act as a natural sedative and also helps in relieving sleeping disorders. As insomnia is a prevalent issue among all ages and genders, mullein tea is a go-to. 

The flowers, leaves, and roots of the mullein plant all possess sedative properties. This makes it an excellent choice for treating sleeping issues. There's still a need for more research to understand better how mullein tea helps treat insomnia and sleep disorders. 

Although most people can enjoy mullein tea with no significant risk of adverse side effects as it is considered safe, a few side effects need to be considered. 

What Are The Side Effects Of Mullein Tea?

There are no documented potential side effects of mullein tea on humans, and the few occurrences of reactions are not fatal. Since no research has been conducted on mullein tea's safety when ingested by breastfeeding or pregnant women, it is highly recommended to consult a doctor or a healthcare professional before drinking it. Other potential side effects mullein tea may cause include:

Skin Irritation

Mullein extract in tea and other forms may irritate the skin for others. Hence, the need to be extra careful when directly handling the herb. To prevent or cure skin irritation, it is advisable to avoid the extract coming in contact with your skin. 

Breathing Issues

It is essential to thoroughly strain mullein tea before drinking as the plant's hair can irritate the throat. The leaves' fluffy hairs may get stuck in the throat, which may cause throat irritation or breathing issues. 

Mullein tea is considered to have few side effects and is generally safe. However, it is essential to thoroughly strain your tea before drinking it and exercise caution when directly handling it to prevent skin irritation. The side effects are not documented by research, so if you notice or feel any adverse side effects after drinking mullein tea, try reducing your intake, stop drinking it, or visit your doctor immediately.  

Is Mullein Good for the lungs?

Mullein tea is medicinal, and it is good for the lungs, even when smoked. Due to its expectorant properties, mullein tea soothes infected or inflamed lungs and eases congestion in the lungs. It is herbal, has a very light smoke, and is non-addictive. It's the perfect extract for lung cleansing. This has been demonstrated in many articles and studies. 

Can you take Mullein tea every day?

While there isn't any clinical evidence to effectively give recommended and specific dosages of mullein tea, traditional users suggest 2g to 3g of dry leaf or 15 ml to 30 ml of fresh leaf and 3g to 4g of flowers daily. 

Is Mullein Toxic?

Studies report that although mullein leaves and flowers are on the GRAS (generally recognized as safe) list of the FDA with no verifiable reports of fatal adverse side effects, mullein seeds may contain the insecticide and fish poison rotenone. 

While rotenone is considered safe in humans, it poses significant toxic risks. If the mullein leaves are contaminated with its seeds, it may prove hazardous over a lengthy period. 

For this reason, nursing or pregnant women and young children or those with severe kidney or liver diseases should not use mullein for a lengthy period. 


The herbal drink called mullein tea has numerous medicinal properties. The antioxidant, antiviral, and anti-inflammatory properties of the mullein plant may help treat viral and bacterial infections and sleeping disorders. 

It is recommended to consume it in healthy quantities of no more than 3 cups a day as while there are no documented potential adverse effects of drinking mullein tea – not much study has been done on excessive consumption. If you experience any side effects or symptoms, take a trip to your doctor or health care provider.
