Christopher Hobbs:
“Mullein leaves are favored in teas and other preparations for treating coughs, laryngitis, colds, excess mucus, and even bronchitis and asthma, and they are considered a tonic for the lungs. They contain soothing mucilage and anti-microbial compounds that help fight infections and have an expectorant and soothing action on the mucous membranes of the respiratory tract. Mullein is one herb recommended for children and adults to add to nearly all respiratory formulas.
Both mullein leaves and flowers are often used as a lymphatic cleanser, which translates to better immune health and alleviates skin problems such as psoriasis. Drops of the flower oil are used in the ear to reduce inflammation, earaches, and infections of the eustachian tubes, inner ear, and ear canal. The root of the plant is sued in teas to ease the symptoms of urinary tract irritations or infections, as well as to benefit the prostate gland.
Mullein has a taste of ASTRINGENT, BITTER and a temperature of COOL.”
Historical Uses
Mullein, also known as velvet plant or flannel leaf, has been used in traditional medicine for centuries. Historically, it was valued for treating respiratory ailments like coughs, bronchitis, and asthma, as well as skin conditions, wounds, and inflammation. The leaves and flowers were often used as teas, poultices, or smoked for their soothing properties.
Modern Clinical Uses
In modern herbalism and naturopathy, mullein is primarily used for:
- Respiratory Support: As an expectorant, it helps expel mucus and soothe irritated airways, often used for bronchitis, colds, and allergies.
- Anti-inflammatory Applications: Infusions of leaves or flowers can reduce swelling and soothe inflamed tissues.
- Ear Infections: Mullein flower oil is a common remedy for earaches and otitis media.
- Skin Health: Mullein preparations are sometimes applied topically to treat wounds, burns, and skin irritations.
Chemistry
Mullein contains several bioactive compounds, including:
- Saponins: Contribute to its expectorant properties.
- Flavonoids: Such as luteolin and apigenin, with antioxidant and anti-inflammatory effects.
- Iridoids: Known for antimicrobial and anti-inflammatory actions.
- Mucilage: Provides soothing effects for the mucous membranes.
- Phenolic acids: Offer antimicrobial and antioxidant properties.
Pharmacology
The pharmacological effects of mullein are largely attributed to its saponins, flavonoids, and mucilage. Key actions include:
- Expectorant: Promotes the clearance of mucus from the respiratory tract.
- Anti-inflammatory: Reduces inflammation in tissues.
- Antimicrobial: Effective against certain bacteria and fungi, including Staphylococcus aureus and Candida albicans.
- Analgesic: Topical applications may reduce pain in certain conditions.
Clinical Trials
- Research on mullein is limited but promising. Clinical trials have highlighted its effectiveness in:
- Respiratory Conditions: Studies show improvement in symptoms of bronchitis and asthma due to its anti-inflammatory and expectorant effects.
- Ear Infections: Mullein flower oil, often combined with other herbs like garlic, has been shown to reduce pain and infection in otitis media.
- Antimicrobial Effects: Preliminary studies suggest activity against resistant bacterial strains and fungi.
Further clinical studies are needed to solidify mullein’s role in modern medicine.
Summary
Mullein is a versatile herb with a long history of use, particularly for respiratory and skin conditions. Modern research supports many of its traditional applications, though more clinical evidence is needed. It is generally safe when used responsibly and continues to be a valued tool in herbal medicine.

Cautions
Mullein is considered safe for most individuals when used appropriately. However:
Allergic Reactions: Rare but possible, particularly in those sensitive to plants in the Scrophulariaceae family.
Pregnancy and Breastfeeding: Safety data is limited; caution is advised.
Topical Use: Avoid applying to deep wounds without professional guidance.
Interactions: No major drug interactions are reported, but consulting a healthcare provider is recommended.
