What Is Mullein Tea & Is It Good for Your Lungs?

It’s the perfect season to make yourself a mug of tea to cozy up with at the end of the night. You may be considering different types of tea for their added benefits, like anti-inflammatory teas or teas that can help you sleep. 

For lung health, mullein tea may be one option on your radar, especially since TikTok is touting the supposed respiratory benefits of mullein tea. But what exactly is mullein tea, and is it really good for your lungs?

We’re breaking down what mullein leaf really is so you know exactly what you’re buying, plus the pros and cons to consider before sipping. Here’s what to know.

What Is Mullein Tea?

Mullein tea is an herbal tea. Derived from the mullein plant, a flowering plant found in mountainous regions of Africa, Asia and Europe, the tea is known to have a naturally sweet, earthy flavor. 

When brewed as a tea, mullein’s nutritional breakdown is comparable to that of other herbal teas, with very few calories and carbohydrates. And like other varieties of herbal teas, mullein tea offers unique compounds that have their own set of nutritional benefits.

Is Mullein Tea Good for Your Lungs?

One of the main claims surrounding mullein tea is that it may improve your lung health. The mullein plant has been historically used to help reduce symptoms of asthma, bronchitis, a cold and other respiratory conditions and illnesses. This isn’t just hearsay: There’s some science that suggests the properties of mullein can be good for your lungs.

A 2021 research study published in the journal MDPI highlights that phytochemicals like quercetin present in mullein provide anti-inflammatory benefits. Lowering inflammation could help your muscles relax, including the muscles in your airway. This may help improve breathing problems caused by the respiratory diseases listed above as well as reducing hoarseness and coughing.

There are other drinks that can provide anti-inflammatory properties and are more nutrient-dense, like a breakfast smoothie. However, it's fair to say that mullein tea is a simple option that may help you feel better.

The Bottom Line

​​Mullein tea is safe to use and may be good to drink for your immune health and potentially to improve respiratory health. However, it isn’t a cure or a medication, so talk to your doctor if you’re having difficulty breathing or your respiratory symptoms are worsening.
