Mullein (Verbascum thapsus) is a tall, soft-leaved plant that has been used in traditional herbal practice across Europe, Asia, and North America for centuries. Its leaves were most often steeped as a tea or dried for smoking blends, and today they appear in respiratory wellness products.
Mullein is one of those roadside plants many people walk past without a second look. Its long record in folk herbalism, though, explains why it still shows up in modern wellness formulas.
Mullein is a biennial plant in the genus Verbascum. In its first year it forms a low rosette of thick, fuzzy leaves, and in its second year it sends up a tall flowering stalk that can reach well over six feet. The leaves are covered in fine hairs, which gives them a felt-like feel that makes the plant easy to recognize.
Native to parts of Europe and Asia, it spread widely and now grows in open, disturbed ground across North America. It thrives in sunny, rocky, or neglected spots, which is why you often see it along roads, fields, and trail edges.
Folk herbal traditions in several regions turned to mullein leaves and flowers, usually as a warm tea or infusion. The tea was strained carefully because the fine leaf hairs can be scratchy in the throat. Herbalists traditionally associated the plant with the chest and throat, and it earned a place in many home remedy collections.
Some historical accounts also mention dried leaves being burned or smoked, and flowers being steeped in oil. These are traditional practices recorded in folk literature, not evidence-based recommendations, and nobody should treat them as medical guidance.

Check Today's PriceToday mullein is more often sold as a concentrated extract than as loose leaf. Extraction pulls the plant compounds from the leaves into a liquid or powder, which makes the amount per serving easier to standardize and measure than a homemade tea.
Reading labels helps here. Look for the plant part used, whether the product lists an extract ratio, and whether the manufacturer follows good manufacturing practices. Those details tell you far more than any claim on the front of a bottle, and they apply to every herbal supplement you consider.
BreathiZen includes mullein leaf extract (10:1) as one of its five named ingredients, alongside ginger root extract, bromelain, organic lemon extract, and Cordyceps militaris. It is a plant-based oral spray taken once daily under the tongue, designed to support respiratory wellness over the long term.
As a dietary supplement, it is not meant to treat or cure any condition, and it is not for emergencies. If you are pregnant, take medication, or have a health condition, check with your healthcare professional first.
No. Mullein has a traditional history in folk herbalism, but that is different from a proven medical treatment. In a supplement it is used to support general wellness, and it should never replace professional care or prescribed medication. Ask your healthcare professional if you are unsure.
Traditionally the leaves and flowers were the parts most often used. Many modern supplements focus on the leaf. A good label will state the plant part and, for extracts, an extraction ratio so you know exactly what the product contains and how it was made.
