A little about great mullein leaf.

The plant

The forms

Most often prepared as a fine-strained leaf infusion (mandatory) using 2 g – 3 g (1.5 to 2 tbsp dried woolly leaf) at 200°F–205°F (93°C–96°C) (Steep 10–15 min covered, then strain through a paper coffee filter or fine cloth).

Before you choose

Check the label for the Latin name (Verbascum thapsus), and choose the form that suits your cupboard.

Cautions & interactions +

General information, not medical advice. Check with a doctor or pharmacist before using this herb if you are pregnant, breastfeeding, giving it to a child, taking medication or managing a health condition.

Who should use caution: Little formal safety data exists for mullein leaf. European regulators have reviewed only the flower, and tests for reproductive harm, genotoxicity and cancer risk have not been done. Use in pregnancy and breastfeeding is not recommended because safety is not established, and use in children under 12 is not established. Avoid it if allergic to the plant. Strain the tea finely, as the leaf hairs can irritate the throat. Do not eat the seeds, which were historically used as a fish poison. See a doctor for breathing trouble, fever, thick discolored sputum, or symptoms lasting over 1 week.

Species & lookalike verification: Great Mullein (Verbascum thapsus, family Scrophulariaceae) is a biennial plant that forms a low basal rosette of thick, silver-grey, flannel-soft woolly leaves in Year 1, then shoots up a single 6-foot candle-like spike of 5-petaled yellow flowers in Year 2.CRITICAL FORAGING DISTINCTION: Never confuse first-year Mullein rosettes with Foxglove (Digitalis purpurea)—Foxglove contains potentially fatal cardiac glycosides (mainly digitoxin), and leaf feel and color are not a safe way to tell them apart. First-year foxglove rosettes have been mistaken for other leafy herbs and caused poisonings, so do not use a wild rosette unless you are certain.

Cupboard storage (amber glass guide): Fluffy, low-density leaves require a roomy glass jar kept dry and dark.

Why MUST you strain Mullein leaf tea through a coffee filter or cloth bag?
Mullein leaf is covered in dense, branching stellate hairs (trichomes) that insulate the plant against sun and drought. In hot water, those tiny stiff hairs detach from the leaf. Unstrained hairs can irritate the throat, so pour the steeped tea through a paper coffee filter or cotton tea sock to remove them.

How do you tell a first-year Mullein rosette apart from toxic Foxglove in the wild?
Do not rely on how the leaf looks or feels. Out-of-bloom foxglove (Digitalis purpurea) has been eaten and brewed as tea by mistake, causing heart poisoning. Buy dried mullein from a supplier rather than picking a wild rosette.

What is the difference between Mullein Leaf and Mullein Flower?
Mullein Leaf has a folk-medicine history of use in infusions for the throat and chest (it contains mucilage polysaccharides, verbascoside, and saponins). Mullein Flowers (the bright yellow petals picked one by one from the tall summer spike) are sweeter and traditionally macerated in olive oil.

Why was Mullein called 'Hag's Taper' and 'Candlewick Plant' in medieval Europe?
Before cotton wicks were affordable, country folk dipped the tall dried stalks of second-year mullein in tallow or beeswax to burn as outdoor torches, or peeled the fluffy down from the leaves to spin into oil-lamp wicks.
