What is Mullein?
This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Mullein, scientifically known as Verbascum, is a genus of flowering plants belonging to the Scrophulariaceae family. This genus comprises approximately 250 species, which are widely distributed across Europe, Asia, Africa, North America, Latin America, and Australia3. Mullein has been recognized for its medicinal properties and has been used in traditional medicine for centuries. Other names include: Aaron’s Rod, Adam’s Flannel, American Mullein, Beggar’s Blanket, Blanket Herb, Blanket Leaf, Bouillon Blanc, Bouillon Jaune, Candleflower, Candlewick Plant, Cierge Cotonneux, Cierge de Notre-Dame, Clot-Bur, Clown’s Lungwort, Common Mullein, Cuddy’s Lungs, Duffle, European Mullein, Faux Bouillon-Blanc, Feltwort, Flannelflower, Fleur de Grand Chandelier, Fluffweed, Gidar Tamaku, Gordolobo, Great Mullein, Hag’s Taper, Hare’s Beard, Hedge Taper, Herbe de Saint-Fiacre, Herbe Saint Fiacre, Higtaper, Jacob’s Staff, Lady’s Foxglove, Longwort, Molène, Molène à Grandes Fleurs, Molène Bouillon-Blanc, Molène Faux-Phlomis, Molène Thapsus, Old Man’s Flannel, Orange Mullein, Oreille de Loup, Oreille de Saint Cloud, Our Lady’s Flannel, Queue de Loup, Rag Paper, Shepherd’s Club, Shepherd’s Staff, Tabac du Diable, Torch Weed, Torches, Velvet Plant, Verbasci Flos, White Man’s Footsteps, Wild Ice Leaf, Verbascum densiflorum, Verbascum phlomides, Verbascum thapsiforme, Verbascum thapsus, Woolen, Woolly Mullein.
Botanical Characteristics
Mullein plants are characterized by their tall, erect stems and large, velvety leaves. The flowers are typically yellow and form dense spikes. One notable species, Verbascum thapsus, is known for its ability to produce up to 180,000 seeds per plant, with seeds capable of germinating even after a dormancy of a hundred years3.
Medicinal Uses of Mullein
Mullein has a long history of use in traditional medicine. The aerial parts of the plant, particularly the leaves and flowers, are used for their therapeutic properties. Mullein is known for its anti-inflammatory, antioxidant, and antimicrobial activities. It has been used to treat a variety of conditions, including respiratory ailments, inflammatory diseases, and infections1 4 5 10.
Anti-inflammatory Properties
The anti-inflammatory properties of mullein are well-documented. Studies have shown that mullein extracts can inhibit the expression of inflammatory markers and reduce inflammation in various models. For instance, Verbascum phlomoides, a species of mullein, has been shown to possess significant anti-inflammatory activity, which is attributed to its high polyphenol content8. Similarly, Verbascum songaricum has been used to treat uterine leiomyomas due to its potent anti-inflammatory properties2.
Antimicrobial Activity
Mullein extracts have demonstrated antimicrobial activity against a range of bacterial pathogens. For example, extracts of Verbascum thapsus have shown antibacterial effects against Klebsiella pneumoniae, Staphylococcus aureus, Staphylococcus epidermidis, and Escherichia coli5. This makes mullein a valuable plant in the treatment of bacterial infections.
Other Therapeutic Uses
Mullein has also been used as an expectorant, sedative, and diuretic. It is effective in treating respiratory conditions such as asthma and spasmodic coughs. Additionally, mullein has been used in the treatment of diarrhea and other gastrointestinal issues5 10.
Agricultural and Industrial Applications
Beyond its medicinal uses, mullein has applications in agriculture and industry. For instance, Verbascum nigrum has been studied for its potential as a natural emulsifier in water-oil systems. The saponins present in the flowers of this species act as surfactants, stabilizing emulsions and making them suitable for use in the food industry4.

Adverse Effects of Mullein
Toxicity at High Concentrations
Mullein extracts showed toxicity in brine shrimp and radish seed germination assays at higher concentrations, indicating potential adverse effects when used in large amounts2.
No Significant Adverse Effects in Clinical Trial
In a clinical trial, 800 mg of oral Mullein capsules per day for 2 months did not show significant adverse effects on myoma size or menstrual bleeding, suggesting it may be safe at this dosage for short-term use1.

How has Mullein Improved Patient Outcomes?
Antibacterial Activity: Mullein extracts, particularly water extracts, have shown antibacterial properties against Klebsiella pneumonia, Staphylococcus aureus, Staphylococcus epidermidis, and Escherichia coli1.
Antitumor Activity: All types of Mullein extracts (water, ethanol, and methanol) have demonstrated the ability to inhibit Agrobacterium tumefaciens-induced tumors in potato disc tissue1.
Toxicity: At higher concentrations, Mullein extracts exhibited toxicity to Brine Shrimp and inhibited radish seed germination and growth1.

Mullein Mechanisms of Action
Anti-inflammatory Activity
Mullein exhibits significant anti-inflammatory properties, primarily attributed to its phytochemicals such as quercetin and other polyphenols2 3. These compounds can inhibit inflammatory markers and processes, supporting its traditional use in treating inflammatory diseases2 3.
Antibacterial Properties
Mullein extracts, especially those prepared in water, have demonstrated antibacterial activity against pathogens like Klebsiella pneumonia, Staphylococcus aureus, Staphylococcus epidermidis, and Escherichia coli1. This supports its use in treating infections.
Antioxidant Effects
The polyphenol-rich extracts of mullein have shown strong antioxidant activity, which helps in scavenging free radicals and protecting cells from oxidative stress3 4. This antioxidant property is beneficial in maintaining overall health and preventing chronic diseases.
Mechanical Defense Mechanism
Mullein’s leaf hairs serve a dual purpose: they act as a mechanical defense against herbivores and help reduce water loss through evapotranspiration. This age-specific defense mechanism makes younger, more pubescent leaves less susceptible to insect attacks6.
Toxicity and Safety
While mullein extracts have shown beneficial biological activities, they also exhibit toxicity at higher concentrations, as observed in brine shrimp and radish seed assays1. This indicates the need for careful dosage consideration in therapeutic applications.
