Mullein leaf extract explained

November 3, 2026 · 5 min read

Imagine walking a country lane in late summer. Beside the fence stands a tall, stately plant with pale, woolly leaves that look as though someone wrapped them in flannel. Many walkers pause to touch one. That plant is mullein, and it is the first ingredient named on every bottle of Vapolung.

Meet Verbascum thapsus

Mullein, known botanically as Verbascum thapsus, is a biennial plant. It forms a low rosette of broad leaves in its first season and then sends up a tall spike in its second, topped with small yellow flowers. It likes open, sunny ground: meadows, roadsides, fields and the edges of woodland. Its leaves are thick, soft and covered in fine hairs, which gives the whole plant a silvery-green look.

On the Vapolung label it appears as mullein leaf extract 10:1. The leaf is the part used here, and the extract is the concentrated form.

A plant with a long folk history

Mullein has been gathered and dried by people across Europe, Asia and North America for a very long time. Traditionally, the leaves were steeped as an herbal tea and kept in home wellness cupboards as a familiar plant to reach for. The brand places it among traditional botanicals for respiratory support, and that is the spirit in which it is included: a time-honoured plant, presented in a modern format.

It is worth being clear about what this means. Traditional use describes how people have worked with a plant through history. It is context and heritage, not a promise of any outcome, and no timeline is attached to this bottle.

What "extract 10:1" signals

An extract is made by drawing the compounds out of the plant material and concentrating them. The ratio 10:1 is a commonly used way of describing that concentration. Our dedicated article on what a 10:1 extract means breaks the idea down in plain language. The short version: it points to a concentrated form of the leaf rather than simply ground-up plant matter.

The exact amount in each serving is not repeated in this article. You will find it on the Supplement Facts panel printed on the bottle label.

Why mullein sits first on the list

Labels commonly list the ingredient the brand wants to highlight at the front, and mullein leads here. It anchors the blend alongside ginger root and organic lemon. If you would like to see how all three work together as a trio, the Vapolung ingredients page lays them out side by side.

Here is a quick snapshot:

  • Plant: mullein, Verbascum thapsus
  • Part used: the leaf
  • Form: extract, 10:1
  • Traditional context: herbal teas and household wellness customs
  • Brand description: a traditional botanical for respiratory support

Doing your own reading

Curious minds like to read around a topic, and that is a great habit. A general literature search such as this mullein search on PubMed will show you what researchers have written about the plant. Think of it as background reading that adds to your understanding of the ingredient.

How the mullein arrives in your day

You will not be brewing a pot of leaves each morning. The format here is an oral mist: shake the 2 fl oz (60 mL) bottle well, then take 4 sprays (0.60 mL) into the mouth or onto the tongue, once daily. The brand suggests mornings, and the product is for adults aged 18 and over.

That small ritual is what makes steady daily use realistic. There is nothing to steep, strain or wait for. For a walk-through of the format, see the how it works page.

  • Shake well before every use
  • Four fine mists, once a day
  • Keep it in a spot you pass every morning
  • Stay consistent, since the idea is steady daily use

Picture the plant through the seasons

One reason mullein is so memorable is its two-year rhythm. In the first year it spreads a flat rosette of soft grey-green leaves close to the soil, like a quiet carpet. By the second year, a tall central stalk reaches skyward, and the plant becomes a landmark in the field. Foragers and gardeners often spot it from far away.

  • Year one: a low rosette of velvety leaves
  • Year two: a tall flowering spike with small yellow blooms
  • Always: a sun-loving plant at home in open, uncultivated ground

Knowing a little of this natural character makes the ingredient on the label feel less abstract and more like a plant you could point out on a weekend walk.
