How to Use Mullein Extract Drops for Lungs & Ears

Mullein extract drops are used in two distinct ways: as an oil infusion dripped into the ear canal to ease earache, and as a tincture or tea taken orally (or occasionally inhaled as steam) to soothe irritated airways. The ear application has a small but genuine body of clinical evidence behind it, while the lung application rests mostly on a long ethnobotanical tradition and laboratory research rather than human trials. Getting practical benefit from either use depends on knowing which preparation suits which purpose, how to apply it safely, and when the drops are not a substitute for medical treatment.

What Is in Mullein That People Find Useful

Mullein, most commonly Verbascum thapsus, produces a surprisingly complex cocktail of plant compounds. The two main classes are terpenes and flavonoids, with several subtypes doing different things. Triterpene saponins like ursolic acid lower surface tension between oily and watery substances, which is one reason herbalists have long believed mullein helps loosen mucus in the respiratory tract. Iridoid glycosides such as catalpol and specioside contribute anti-inflammatory activity. Phenylpropanoid compounds, especially verbascoside, show antioxidant and mild antimicrobial properties in lab settings. And the flavonoids round out the picture with their own anti-inflammatory effects.¹

None of these compounds are present in blockbuster concentrations the way, say, caffeine is in coffee. The practical consequence is that mullein works gently and gradually rather than delivering a sharp pharmacological punch. That gentle profile is part of why it has a reputation as a safe home remedy, but it also means you should not expect dramatic, fast-acting results from a few drops.

Mullein Oil Drops for Ear Pain

The ear use has the strongest footing in both tradition and clinical testing. Across Mediterranean folk medicine, a liniment of mullein flowers macerated or gently heated in olive oil has been a standard earache remedy for centuries, documented in regions of Spain including Cataluña, the Balearic Islands, and Navarra.¹ The method is simple: dried or fresh mullein flowers steeped in warm olive oil for days to weeks, then strained and stored in a dark bottle.

A clinical trial published in Archives of Pediatrics & Adolescent Medicine tested a naturopathic ear drop product called Otikon Otic Solution, which combines mullein with garlic, calendula, and St. John’s wort in olive oil. Children with ear pain from acute otitis media received either the herbal drops or conventional anesthetic ear drops. Both groups showed statistically significant improvement in pain scores over the study period, and the herbal drops performed comparably to the anesthetic product at each follow-up application.²

A few things to note about that trial. The herbal formula was not mullein alone; it contained multiple botanical ingredients, so it is difficult to attribute the pain relief to mullein specifically versus the garlic or St. John’s wort. The study also measured pain management, not resolution of the underlying infection. And the children in the study were being monitored by physicians. Still, the finding is encouraging for people who want a gentle option for ear discomfort while an infection runs its course or while waiting for antibiotics to kick in.

How to Apply Mullein Ear Drops

Whether you buy a prepared mullein-garlic ear oil or make your own, the application technique matters more than most people realize. Warm the bottle by holding it in your closed hand or placing it in a cup of warm (not hot) water for a minute or two. Cold oil in the ear canal is uncomfortable and can cause dizziness. Tilt your head so the affected ear faces up, use a dropper to place three to five drops into the ear canal, and stay in that position for a few minutes to let the oil settle. A small cotton ball at the opening of the ear can keep the oil from draining immediately.

You can repeat this two to three times a day. Most commercial mullein ear oils suggest use for up to three days for acute ear discomfort, with the clear caveat that if symptoms worsen or do not improve, you should see a healthcare provider. One absolute rule: never put oil drops into an ear if you suspect a ruptured eardrum. Signs include sudden sharp pain followed by relief, fluid drainage, or significant hearing loss. Oil in the middle ear through a perforation can cause serious problems.

Mullein for Respiratory and Lung Support

The lung side of mullein’s reputation is older and more deeply embedded in folk medicine, but the clinical evidence is thinner. Herbalists have recommended mullein leaf tea and tinctures for centuries to soothe dry coughs, ease bronchial irritation, and help clear congestion. The saponins in mullein are thought to act as mild expectorants by reducing the surface tension of mucus, making it easier to cough up. The anti-inflammatory flavonoids and verbascoside may calm irritated tissue in the throat and upper airways.¹

These mechanisms are plausible and consistent with the plant’s chemistry, but they have not been tested in the kind of controlled human trials that would let anyone say “mullein treats bronchitis” with confidence. Most of the respiratory evidence comes from in vitro (test tube) studies and from the sheer consistency of its traditional use across many cultures. That consistency is worth something, but it is not the same as a clinical trial showing measurable improvement in lung function or cough frequency.

Oral Tinctures and Teas

For respiratory use, mullein is most commonly consumed as a tea or a liquid extract (tincture). To make mullein leaf tea, steep one to two teaspoons of dried mullein leaves in a cup of just-boiled water for ten to fifteen minutes, then strain carefully through a fine cloth or coffee filter. Straining is important because mullein leaves are covered in fine hairs that can irritate the throat if they make it into the drink, which rather defeats the purpose of a soothing respiratory tea.

Tinctures are alcohol-based extracts, typically taken as 30 to 60 drops (roughly one to two dropperfuls) in a small amount of water, two to three times daily. Some people prefer glycerin-based (alcohol-free) extracts, which taste sweeter and are easier to give to children, though glycerin extracts may pull out a slightly different profile of plant compounds than alcohol does. Commercial mullein tinctures vary widely in concentration, so following the specific product’s dosage instructions is more reliable than any general guideline.

Smoking and Vaping Mullein

You will encounter claims online that smoking dried mullein leaf is good for the lungs. This deserves a blunt response: inhaling combustion products of any plant material introduces tar, particulate matter, and carbon monoxide into your airways. There is no credible evidence that smoking mullein provides a net respiratory benefit. Some herbalists have historically used mullein in herbal smoking blends as a “base” herb to replace tobacco, arguing it is less harmful than tobacco specifically, but “less harmful than tobacco” is a very low bar and is not the same as “helpful.” If you want mullein’s respiratory compounds, drink the tea or use a tincture. If you want to inhale something warm and moist, a steam inhalation with mullein tea added to the water is a far safer option, though even that has only anecdotal support.

Buying Commercial Drops Versus Making Your Own

This choice matters more than it might seem. A study examining microbial contamination in herbal medicines found that homemade preparations had a significantly higher risk of harboring pathogenic bacteria compared to commercially produced herbal products.³ When you are dripping something into your ear canal or swallowing it, bacterial contamination is not a trivial concern. Commercial products are typically manufactured under conditions that control for microbial load, use standardized extraction methods, and undergo at least basic quality testing.

If you still want to make your own mullein oil or tincture, a few precautions reduce the risk:

Start with clean, dry plant material. Moisture left on flowers or leaves before infusing creates a breeding ground for mold and bacteria. Dried mullein is safer than fresh for oil infusions.
Use the warm infusion method. Gently heating the oil (not frying it) with the mullein in a double boiler for a few hours extracts compounds more quickly and exposes the oil to temperatures that reduce microbial survival, compared to a weeks-long cold infusion sitting at room temperature.
Strain thoroughly. Fine muslin or cheesecloth removes the plant solids that can harbor bacteria over time. Strain twice if you can.
Store in a dark glass bottle in a cool place. Oil-based preparations go rancid, especially in heat and light. A refrigerated mullein ear oil will keep longer and is less hospitable to microbial growth. Discard any oil that smells off or has visible cloudiness.
Label with the date. Homemade mullein oil is best used within a few months, not kept indefinitely.

Why Wildcrafted Mullein Can Be Dangerous

Mullein grows readily along roadsides, in vacant lots, beside railroad tracks, and in other disturbed urban and industrial landscapes. This is not a coincidence. The plant is a phytoextractor, meaning it actively pulls heavy metals from contaminated soil and concentrates them in its tissues.⁴ Research has identified mullein as a hyperaccumulator for cadmium specifically, and it also takes up other metals from polluted ground.⁴ A separate study surveying mullein across the St. Louis metropolitan area confirmed that the plant thrives precisely in the urbanized areas where soil metal concentrations are highest.⁵

Picking mullein from a roadside, an old industrial area, or even a typical city lot and then making tea or ear drops from it could mean ingesting or absorbing cadmium, lead, or other metals that the plant has efficiently extracted from the soil. This is especially concerning for children and for anyone using mullein regularly over weeks or months. If you want to wildcraft mullein, do it in rural areas well away from roads, industrial sites, and agricultural fields where pesticides or fertilizers may have been applied. Better yet, grow it yourself in clean soil or buy from suppliers who can tell you where their mullein was harvested.

When Mullein Drops Are Not Enough

For ears, mullein oil is a comfort measure, not a treatment for infection. Acute otitis media in children often resolves on its own, and guidelines in many countries include a “watchful waiting” period of 48 to 72 hours for uncomplicated cases in children over two years old. During that window, mullein-garlic ear drops can help manage pain. But if your child has a high fever, severe pain, symptoms that are worsening after two to three days, or pus draining from the ear, that situation needs medical evaluation and possibly antibiotics. Ear drops of any kind are also off-limits when there is a possibility of eardrum perforation, as mentioned earlier.

For lungs, mullein tea or tincture is a reasonable supportive measure for a minor cough or mild upper respiratory irritation. It is not a substitute for medical care for pneumonia, asthma exacerbations, chronic obstructive pulmonary disease flare-ups, or any breathing difficulty that involves wheezing, chest tightness, or shortness of breath at rest. The gentle expectorant and anti-inflammatory properties that mullein may offer are simply not strong enough to manage serious respiratory conditions. Think of it as a warm, soothing companion to proper treatment rather than a replacement for it.

Allergies and Skin Reactions

Mullein belongs to the family Scrophulariaceae, and allergic reactions to it are uncommon but not unheard of. People with known sensitivities to plants in the Asteraceae (daisy) family sometimes cross-react to mullein, though the two families are not closely related and cross-reactivity is unpredictable. The fine trichomes (tiny hairs) covering mullein leaves can also cause mechanical irritation to skin or mucous membranes, which can look and feel like an allergic reaction even when the immune system is not involved.

If you are using mullein ear drops for the first time, test a small amount on the skin behind your ear or on your inner wrist and wait a few hours. Any redness, itching, or swelling suggests you should not put that preparation in your ear canal. For oral use, start with a small amount of tea and pay attention to how your throat and stomach feel. True allergic reactions to mullein taken orally are rare in the literature, but gastrointestinal upset is possible, especially with strong preparations or large doses.

Drug Interactions and Special Populations

Mullein has not been studied well enough in pregnant or breastfeeding women to make safety claims in either direction. Most herbalists advise caution simply because the data does not exist. The saponin content is the main theoretical concern during pregnancy, since some saponins in high doses can affect uterine smooth muscle, though this has not been specifically demonstrated for mullein’s particular saponins at the concentrations found in tea or tincture.

If you take prescription medications, the interaction risk with mullein is low but not zero. Mullein may have mild diuretic properties, which could theoretically amplify the effects of diuretic drugs or alter the absorption of medications taken at the same time. The practical risk is small with occasional use, but if you are taking mullein daily alongside prescription drugs, mention it to your pharmacist or doctor. Alcohol-based tinctures also carry a small but real alcohol load, which matters for people taking metronidazole, certain antifungals, or anyone avoiding alcohol for medical or personal reasons. Glycerin-based extracts avoid that issue entirely.

Choosing Between Leaf and Flower Preparations

Not all mullein products are the same part of the plant. Mullein leaf is the standard for respiratory teas and tinctures. The leaves contain the highest concentration of saponins and mucilage, the slippery polysaccharides that coat irritated throat and airway tissue. Mullein flowers are the traditional choice for ear oils. They are richer in the volatile and semi-volatile compounds that infuse into olive oil and that have historically been associated with pain-soothing and mild antimicrobial activity in the ear canal.

Some products combine both, and some ear oils include additional herbs like garlic (for its allicin content, which has demonstrated antibacterial properties) and calendula (for its anti-inflammatory reputation). The clinical trial discussed earlier used a multi-herb formula, not pure mullein, so if you are trying to replicate that specific evidence, a combination product is closer to what was actually tested.² If you prefer a single-ingredient approach, pure mullein flower oil is the traditional preparation for ears, and pure mullein leaf tea or tincture is the traditional preparation for respiratory use.
