What to Know About Mullein
Plants have played a meaningful role in wellness traditions for centuries, and mullein is one herb that has remained relevant across generations. Historically used in herbal practices, mullein is especially known for supporting respiratory comfort and easing physical irritation. Today, it’s commonly found in teas, extracts, capsules, and infused oils.
So what makes mullein so widely respected, and how is it used today? In this blog post, we’ll take a closer look at mullein’s background, potential benefits, and important considerations. While herbal remedies can be supportive, they should complement, not replace, professional medical care.
Getting to Know Mullein
Mullein has a long-standing presence in traditional herbal systems and is often associated with whole-body support.
What Is Mullein?
Mullein (Verbascum thapsus) is a tall flowering plant belonging to the snapdragon family (Scrophulariaceae). Though frequently dismissed as a common roadside plant, mullein is native to Europe, Asia, and North Africa and now grows widely across the globe. Its soft, velvety leaves and towering flower stalk make it easy to identify. Traditionally, mullein has been used to support breathing comfort and general wellness.
Growing Characteristics
This hardy plant thrives in sunny, dry environments such as open fields, meadows, and along roadsides. Mullein typically follows a two-year growth cycle. During the first year, it produces a low cluster of fuzzy leaves. In its second year, a central stalk emerges and can grow up to six feet tall, topped with small blossoms ~ most often yellow, though some species bloom in lighter or darker shades.
Common Types of Mullein
With more than 300 species in existence, not all mullein varieties are used in herbal preparations. Common mullein (Verbascum thapsus) and great mullein (Verbascum densiflorum) are the most frequently used due to their traditional association with respiratory comfort. Other species, such as moth mullein (Verbascum blattaria), share similar properties but are less commonly utilized.
Potential Health Benefits of Mullein
Mullein has historically been associated with respiratory wellness, though it may offer additional supportive properties.
Supporting Respiratory Comfort
One of mullein’s most well-known uses is as a natural expectorant. It helps loosen mucus in the airways, making it easier for the body to clear congestion. This may ease throat and chest irritation and promote more comfortable breathing, particularly during seasonal challenges.
Mullein is often prepared as teas, syrups, or liquid extracts. Water-based preparations are especially popular. Some research suggests mullein extracts may help limit the growth of certain bacteria linked to respiratory concerns, though more studies are needed to fully understand this effect.
Inflammation and Tissue Soothing
Mullein contains naturally occurring compounds such as flavonoids and saponins, which may help calm irritated tissues and support the body’s inflammatory response. Traditionally, mullein has been used to soothe sore throats and, when applied topically, may help calm minor skin irritation through oils or poultices.
Additional Traditional Uses
Beyond respiratory support, mullein has been used to promote digestive comfort and may help with occasional bloating or irregularity. It also contains antioxidant compounds that may support immune health. While these uses are rooted in tradition, scientific research in these areas remains limited.
Using Mullein Responsibly
Mullein is generally considered gentle when used appropriately, but understanding its forms and preparation methods is important.
Common Forms of Mullein
Mullein can be found in several preparations, allowing for flexible use:
Dried Leaves: Often brewed into tea or used in tinctures and topical preparations
Tea: A mild, soothing beverage commonly used for throat and respiratory comfort
Tinctures: Liquid extracts made with alcohol or glycerin for concentrated use
Capsules: Ideal for those who prefer a tasteless, pre-measured option
Infused Oils: Typically made from mullein flowers and applied topically for skin or ear support
Making Mullein Tea
Mullein tea is one of the most popular ways to use this herb:
Bring water to a boil
Add 1–2 teaspoons of dried mullein leaves
Steep for 5–10 minutes
Strain thoroughly to remove fine plant hairs before drinking
Straining is important, as the tiny hairs on mullein leaves can irritate the throat if consumed.
Dosage Considerations
The appropriate amount of mullein depends on the form used, individual health status, and age. Because herbal needs vary, consulting a qualified healthcare provider is recommended, especially if you have underlying conditions or take prescription medications.
Choose mullein products that are third-party tested to help ensure quality and purity.
Safety and Precautions
While mullein is widely considered safe, certain precautions should be kept in mind.
Possible Side Effects
Most people tolerate mullein well, but allergic reactions can occur, particularly in those sensitive to plants in the snapdragon family. Symptoms may include skin irritation, itching, or swelling. Digestive discomfort has been reported in rare cases.
Mullein may also interact with medications, especially those affecting the respiratory system or causing sedation. Anyone taking medication for asthma, bronchitis, or related conditions should speak with a healthcare provider before use.
Who Should Use Caution?
Due to limited safety data, mullein is generally not recommended during pregnancy or breastfeeding unless approved by a healthcare professional.
What The Research Says About Mullein
Modern interest in mullein has grown due to its long-standing traditional use and emerging research.
Scientific Insights
Studies suggest mullein contains antioxidant compounds that may help protect cells from oxidative stress. While these findings are encouraging, more clinical research is needed to confirm their significance.
One clinical trial examined a mullein-based cream for episiotomy wound healing. In a randomized, double-blind study involving 93 participants, those using the mullein formulation experienced significantly improved healing after 10 days compared to a placebo group. Although promising, these findings require further validation.
Another species, wavyleaf mullein (Verbascum sinuatum), has been studied for its polyphenols and iridoids, bioactive compounds that may offer antioxidant support. Researchers note that compound levels vary depending on growing conditions and processing methods, making standardization an ongoing challenge.
Using Mullein Alongside Other Approaches
Mullein is often combined with complementary herbs such as mint, rosemary, mallow, or honey to support respiratory and musculoskeletal comfort. Its traditional use for joint or inflammatory concerns is typically linked to its soothing properties.
As with any complementary approach, professional guidance is recommended before combining mullein with other therapies.
Core Insights
Mullein has a long history of use for supporting respiratory comfort and overall wellness, and it’s available in forms such as teas, tinctures, capsules, dried leaves, and infused oils.
Most people tolerate mullein well, but potential side effects or interactions may occur—especially for those with existing health conditions or who take medications.
While mullein shows promise as a supportive herbal option, it’s best used thoughtfully and with guidance from a qualified healthcare professional.
