A growing body of peer-reviewed research supports mullein's long reputation as a herb for the lungs, throat and airways. Below is a summary of the key findings from published papers on the mullein plant, with full references provided beneath each section. These summaries describe the research on mullein, and this product is a dietary supplement.
Mullein (Verbascum thapsus), also known as great mullein or common mullein, is a tall plant with soft, woolly leaves that has been used as a traditional medicine for the lungs, skin and throat. A 2022 review in Phytotherapy Research describes a herb with a long history of therapeutic importance, valued particularly as an astringent and calming agent, and still used today in traditional formulations. The authors catalogued a wide variety of plant compounds in mullein, including flavonoids, iridoid and phenylethanoid glycosides, saponins, vitamin C and minerals, and reported that experimental studies have documented antioxidant, anti-inflammatory, antibacterial, antiviral and antifungal properties.

A review of all the scientific research on common mullein found that the plant has been used since ancient times for pulmonary problems and spasmodic coughs, and that its popularity has been growing steadily. The authors noted that the use of mullein extracts in folk medicine had begun to be supported by an increasing number of research studies, ranging from plant tissue cultures to the biological properties of the plant itself.

Researchers at the Medical University of Łódź describe mullein as a highly valued herbal drug, traditionally used for inflammation, spasmodic coughs and other respiratory tract complaints. They explain that its phenolic compounds are considered responsible for the herb's anti-inflammatory and antimicrobial activity, and they measured high levels of flavonoids such as diosmin and luteolin 7-glucoside, along with the phenylethanoid verbascoside, in mullein flowers.

A 2022 review in the Journal of Agricultural and Food Chemistry examined plant-based support of respiratory health and lists mullein among the botanicals it covers, alongside elderberry, ginger, licorice, horehound, nettle and coneflower. The authors highlight a series of botanical interventions with different and often overlapping mechanisms of action to support the respiratory system, and point to the plants' metabolites as a promising area for future research.

A polyphenol-rich extract of mullein (Verbascum phlomoides) was found to contain rosmarinic acid, caffeic acid, ferulic acid and quercetin, among other compounds. Depending on concentration, the extract scavenged free radicals, and at 100 and 200 µg/mL it inhibited TNF-α-induced expression of ICAM-1, an inflammation-related adhesion molecule, by 55–58.8% in human endothelial cells. The authors note that mullein is thoroughly documented in European folk medicine for its soothing action on the respiratory tract.

A 2021 study in Molecules analysed a water-based leaf extract of common mullein (Verbascum thapsus) and identified six phenylethanoid glycosides and a total phenolic content of 124 mg gallic acid equivalents per gram of extract. Tested in two cell models, including human cells, the extract significantly decreased most of the inflammatory markers measured. The authors concluded that mullein leaf extract has the potential to moderate the inflammatory response.

Mullein species have been used since ancient times for respiratory disorders and inflammatory skin conditions. Researchers isolated acylated iridoid diglycosides from oval-leaved mullein (Verbascum ovalifolium) and tested them on human neutrophils, a key type of immune cell. The compounds reduced the release of the inflammatory messengers TNF-α and IL-8, and the diacyl derivatives showed the most potent effects.

A 2021 review in Biology looked at how mullein has been used in Spanish folk medicine, for the respiratory, circulatory, digestive and musculoskeletal systems and for infections, and examined the chemistry of the ten Verbascum species in Spain's inventory of traditional knowledge. The authors concluded that most of common mullein's traditional uses could rely on the anti-inflammatory action of phytochemicals such as quercetin, which could help explain why the plant has been used so widely for respiratory complaints.

Saponins isolated from the flowers of a Verbascum species were tested in animal models at 100 mg/kg. They showed anti-inflammatory activity in a carrageenan model, linked to reduced cyclooxygenase activity, and notable pain-relieving activity, without any apparent acute toxicity or gastric damage.

Researchers at Clemson University prepared common mullein extracts in water, ethanol and methanol and screened them in laboratory bioassays. Antibacterial activity, especially from the water extract, was observed against Klebsiella pneumoniae, Staphylococcus aureus, Staphylococcus epidermidis and Escherichia coli.

In a study published in Natural Product Research, an extract of Verbascum thapsus was tested against pseudorabies virus, a herpesvirus, in cell culture. It inhibited plaque formation at just 35 µg/mL, far below the concentration at which it affected the cells themselves, giving selectivity indices of 31–41. Inhibition reached 99% when the virus was incubated with the extract and 70% when cells were pre-treated with it before exposure. The authors concluded that mullein may contain bioactive compounds that act on the virus, mostly during the stage in which it attaches to cells.

A 2024 study in Heliyon on Verbascum thapsus, a plant the authors note has been used in traditional medicine for lung disease, sore throat, wound healing and whooping cough, isolated its most active fraction and found concentration-dependent antimicrobial activity. Analysis showed that the main compounds were phenolic acids (4-hydroxybenzoic, chlorogenic, caffeic, p-coumaric and ferulic acid) and the flavonoid rutin, and the extract also showed antioxidant activity.

Flavonoids are a large family of natural plant compounds found in fruits, vegetables, leaves, flowers and tea, and they are among the compounds reported in mullein, including quercetin, diosmin, luteolin and rutin in the studies above. A widely cited overview describes them as plant substances that have attracted wide interest in nutrition and health research.

Mullein has long been prepared as dried leaf, tea, capsules and alcohol extracts, and the research describes all of these forms. Our Mullein Drops follow the tincture tradition in a simple, modern form: mullein leaf extract with its natural flavonoids and chlorophyll, the green pigment found in the leaf, and no other herbs. You get one well-documented plant in a measured dropper bottle, with a short ingredient list and nothing to guess about.

Everyday air is full of dust, smoke, pollen and dry indoor heat, and the scratchy, tickly feeling has become so normal that you were never shown the old way of caring for your airways.
Your cupboard is full of lozenges, sprays and syrups — menthol sweets, throat sprays, hot lemon sachets. They feel nice for a minute, so you keep buying them and carry on with a chesty, tickly feeling that never really settles. It’s not a plan. It’s a revolving door. And it’s one of the most common frustrations people mention about everyday chest comfort.
Menthol sweets, throat sprays, hot drinks — they soothe for a moment, then wear off. Every sachet you stir is a short-lived fix, and the next cold snap, dusty room or smoky evening brings the same tickle straight back.
Most of us got no lessons in traditional herbs growing up. Nobody explained the plain leafy plants our grandparents kept in the cupboard. And when the shop-bought stuff stops working? You’re told to just put up with it.
It’s called Mullein — a tall plant with soft, woolly leaves. And chances are, nobody ever mentioned it to you.
Here’s the story: for centuries, people across Europe dried the soft leaves of the mullein plant and steeped them into a warm cup for the chest and throat. It sat in cottage kitchens and village apothecaries as a daily comfort herb long before lozenges and sprays existed.
Published reviews describe it as a traditional lung herb used for airway comfort. People reached for it in cold, damp seasons, in smoky rooms, and whenever the chest felt tight and scratchy and they wanted something simple and familiar.
It’s not magic. It’s not a cure. It’s a traditional herb with generations of use behind it.
What do the papers actually say? They’re mostly looking at traditional use and lab studies — plant chemistry, folk records, literature reviews. None of it claims mullein treats any condition. So we describe it honestly, as a herb for daily comfort.
Village herbalists used mullein leaf in warm drinks for the chest centuries before cough sweets existed.
Country herbalists across Britain and Europe prized it for dry, tickly throats and winter chests. Reviews describe its traditional use for the lungs and airways — they knew something.
Plant research has taken an interest for years: flavonoids — natural plant compounds found in mullein leaf — are being studied in the laboratory for their part in the plant’s natural chemistry.
Then modern life moved on, and a plain herb got left on the shelf. Fewer people learned it.
Now shops are full of sweets, sprays and syrups instead of the leafy herb — same wish, very different ingredients.
You’re not discovering something new. You’re finding what older generations kept in the cupboard.

Tea means steeping and straining, and capsules rely on your body to break down the capsule shell before the contents are released. Nutrition Therapy’s Mullein Drops are a ready-to-take liquid extract. You measure one dropperful and it goes straight under the tongue or into a glass of water. That’s the whole idea behind our one-herb dropper bottle.
Everyone is different and herbs affect people differently, so we promise no particular result. Traditionally, mullein is taken as a steady habit, so many people give it at least 2–3 weeks to settle into a routine and then carry on for a few months before deciding how it suits them. Consistency matters. This is a traditional herb, not a quick-fix lozenge. It’s a daily habit.
Mullein is a traditional herbal ingredient — but everyone is different. Some people prefer to start with a smaller amount to see how they feel, especially in the first few days. If anything feels off, stop taking it. If you have a sensitive stomach, you can stir the drops into water rather than taking them straight under the tongue.
We always recommend consulting your healthcare provider before adding any supplement to your routine, especially if you’re currently taking prescription medications. Mullein is a natural herb, but it is still a herbal supplement and may not suit everyone, so check first.
No. Nutrition Therapy’s Mullein Drops are not a medicine. They are a dietary supplement made from mullein leaf extract, a herb with a long record of traditional use. Reviews describe traditional use for airway comfort and mostly laboratory research, not clinical proof of any effect on a condition. No prescription required.
That’s a very common question. Plenty of people have tried sweets, sprays and teas that only last a moment or that needed brewing and measuring. Mullein Drops work differently in one respect: it’s a single herb in a liquid you take the same way every day, with nothing else added to the leaf extract, flavonoids and chlorophyll. We can’t promise it suits everyone, which is why the guarantee exists.
Every bottle of Nutrition Therapy’s Mullein Drops is backed by a 60-day money back guarantee. If you don’t feel like it’s making a difference, you get your money back. We’re confident enough in what this formula does to take that risk off your shoulders entirely.
1 dropperful twice daily. You can place the drops directly under your tongue for an easy routine, or mix them into a small amount of water or juice. Take consistently at the same time each day for best results.
Mullein has been used traditionally for centuries and has been the subject of laboratory research, but large human trials are still missing. We recommend never going over the label dose or using it without checking in first if you have a health condition. Reassess after a few months of consistent use, based on how you feel. Your healthcare provider can help you determine the right approach for your situation.
No. Nutrition Therapy’s Mullein Drops are a dietary supplement and do not require a prescription.
