Safety & Cautions
Safety information on fileBotanical Description
A biennial forming a basal rosette of large, thick, soft grey-green velvety leaves in the first year, and in the second a tall (1–2 m) spike of small yellow flowers. The leaves and flowers are used.
Also known as: Great Mullein, Candlewick, Lungwort
Historical Background
Mullein has been a European respiratory herb since antiquity — used for coughs, asthma, and chest complaints, and as 'candlewick' (the felted leaves and dried stalks). It reached North America with colonists and was widely adopted for cough and ear oils.
Earliest recorded uses: Dioscorides; European folk medicine for chest and skin complaints.
Cultural significance: Mullein's tall flower stalks were dipped in tallow as torches and its felted leaves as lamp wicks and shoe insoles — a plant of the hearth and the chest in equal measure.
Traditional preparations:
- Leaf/flower infusion
- Mullein flower oil (topical)
- Steam

Modern Evidence
Mullein has a long respiratory tradition but very limited clinical evidence; most support comes from traditional use and in vitro observations. It is not a treatment for asthma, infection, or chronic lung disease.
