Why Organic Mullein Leaf Tea Should Be Your Next Health Drink

8 min read MAR 25, 2025

Herbal teas have become very popular for their wide range of health benefits. Made from different parts of plants, these teas contain helpful compounds that can support wellness in various ways.

One such herbal tea that is gaining attention is mullein tea, made from the leaves of the mullein plant. Mullein is a flowering plant that grows wild in many parts of the world. It has a long history of being used to treat respiratory illnesses in traditional medicine.

Now, modern research is confirming some of the traditional uses of mullein. Organic mullein leaf tea is an excellent choice as a health-promoting drink due to its abilities to benefit respiratory health, fight inflammation, combat bacteria and viruses and provide antioxidants.

The Health Benefits of Organic Mullein Leaf Tea

Respiratory Health Support


One of the main uses of mullein leaf tea is for respiratory issues. Mullein leaf contains compounds that make it act similarly to an expectorant. This means it can help loosen mucus secretions in the airways and make coughs more productive.

Drinking mullein tea may help clear congestion from colds or allergies by thinning and expelling phlegm. This expectorant quality also makes mullein potentially useful for treating chronic lung diseases like asthma, bronchitis and chronic obstructive pulmonary disease (COPD).

Studies performed in the lab show mullein’s ability to relax airway muscles and reduce swelling in the respiratory tract. Many medical herbalists report success in using mullein leaf preparations to lessen inflammation in patients with frequent coughs or difficulty breathing.

So far, scientific support for this traditional use requires more research on humans. But the anecdotal and test tube evidence is encouraging.

Antiviral and Antibacterial Properties

Exciting new research indicates that mullein leaf exhibits antiviral and antibacterial properties that may prevent infections or hasten recovery. Lab experiments found several unique compounds in mullein that strongly inhibit influenza viruses.

Additional studies noted potent effects against pathogens like the bacteria Streptococcus pyogenes and Staphylococcus aureus. S. aureus causes a wide range of sometimes life-threatening infections.

The antiviral and antibacterial powers of mullein tea come from compounds like flavonoids, coumarin and hesperidin. However, the difficulty is that these substances tend to lose potency during digestion. So, while mullein shows success against microbes in the lab, we need clinical trials to prove similar benefits in the human body. Still, protecting against infection is a promising application.

Anti-inflammatory Effects


Chronic inflammation contributes to diabetes, heart disease, arthritis and stroke. Thankfully, mullein leaf tea delivers anti-inflammatory phenolic compounds that may guard against these threats.

Three potent inflammation-reducing flavonoids contained in mullein tea are luteolin, quercetin and apigenin. Recent experiments found another key mullein constituent, called verbascoside, decreased swelling by over 53% in animal arthritic joints.

Although absorbing sufficient quantities of these beneficial phytochemicals poses challenges, routine consumption of mullein tea likely imparts protective effects by lowering background inflammation. Over time, this impact could translate into noticeable improvements in inflammatory conditions.

Antioxidant Properties

Oxidative stress from an accumulation of free radicals leads to cellular damage implicated in cancer, coronary artery disease and neurodegenerative disorders. Rich in antioxidants, mullein leaf tea neutralizes these dangerous free radicals before they can attack healthy tissues.

Prominent antioxidants in mullein include flavonoids like quercetin along with phenolic acids such as caffeic acid and chlorogenic acid. These compounds protect delicate lipids, proteins and DNA stands from destruction by donation electrons to stabilize runaway oxidation cascades.

Although higher doses worked best in lab trials, even small amounts of antioxidants from frequent mullein tea intake allows the body to gradually clean up free radicals that drive disease processes and premature aging.

Nutritional Profile of Mullein Leaf Tea

With only 2 calories and less than 1 gram of carbohydrates per cup, mullein leaf tea fits into almost any eating plan. You can enjoy its health benefits without worrying about excess calories or spiking blood sugar.

The tea contains trace amounts of vitamins and minerals from the leaves. But its true value comes from unique healing compounds like mucilage, flavonoids and more. Be aware that adding mix-ins impacts nutrients. For example, 1 teaspoon of sugar has 16 calories and 4 grams of carbs.

Compared to other common herbal teas, mullein has a similar nutritional profile. It may contain slightly more beneficial phytochemicals thanks to medicinal properties absent in teas like peppermint or chamomile.

Ultimately, the health promoting aspects come from helpful substances that require minimal calories or nutrients for effective delivery.

Possible Side Effects

Available data indicates mullein leaf tea is very safe for most healthy adults. There are no commonly reported side effects. Rarely, handling the raw plant causes contact skin irritation.

There are no known toxicities or contraindications except in cases of allergy. Still, pregnant or nursing mothers should exercise caution until more definitive safety research is conducted.

When making mullein tea, carefully filter out fine leaf hairs that can irritate the mouth and throat. Cheesecloth or a coffee filter works well for this purpose. While not dangerous, the texture of stray plant hairs creates unnecessary discomfort.

Wait 10-15 minutes after steeping before pouring the finished tea through the filter. Also, do not consume teas made from mullein seeds, as they harbor a potentially toxic compound called rotenone.

As long as you avoid the seeds and strain out the leaf hairs, mullein tea poses no significant downside as an herbal infusion.

How to Prepare and Enjoy Organic Mullein Leaf Tea

Making mullein tea at home starts with high-quality ingredients. Search for mullein leaves certified organic to avoid residual pesticides or adulterants. Purchase whole, cut or sifted mullein leaves in bulk or pre-packaged mullein tea bags.

Place 2 teaspoons of dried leaves or 1 tea bag into a cup and add freshly boiled water. Cover and steep for 15 minutes up to 2 hours to extract full benefits. Strain the finished tea through a porous coffee filter, cheesecloth or fine mesh sieve lined with muslin cloth. This removes all hairy particulates.

Drink 1 cup hot or chilled up to 3 times daily. The taste resembles a mild green or black tea. For those who enjoy sweetened tea, use healthy alternatives like raw honey, maple syrup or stevia instead of refined sugar.

You can also spice things up by steeping with mint, cinnamon, lemon or ginger. Just avoid adulterating with heavy cream or sweetened condensed milk as the objective entails maximizing nutritional gain within a modest caloric load.

Ultimately, the simplicity of pure mullein tea provides an adaptable way to access this herb’s precious healing elements.

Conclusion


Mullein leaf tea offers many benefits along with an attractive nutritional profile devoid of calories, carbs and caffeine. It tastes pleasant hot or chilled. Preparation involves a simple steeping method followed by straining out plant hairs.
