The soft-leaved plant at the top of the label — and what "10:1" actually tells you.
Mullein sits at the top of the BreathiZen label. It is also one of the oldest plants in traditional breathing routines. Here is what you should know.
Mullein (Verbascum thapsus) is a tall plant with soft, fuzzy leaves and yellow flowers, traditionally used in teas for chest comfort. BreathiZen lists it first as Mullein Leaf Extract 10:1, meaning roughly ten parts of dried leaf go into one part of extract.
Mullein is a hardy plant found along roadsides and fields in Europe, Asia and North America. Its large, velvety leaves have been dried and steeped in traditional herbal teas for the chest and throat for generations. In BreathiZen it is the lead plant for everyday chest comfort.
An extract ratio tells you how concentrated a plant extract is. A 10:1 ratio means about ten kilograms of dried leaf are used to make one kilogram of extract. It describes concentration — not the amount in each spray, which the label does not print.

Four pumps a day, from $49 a bottle, with a 60-day money-back guarantee.

Mullein is a traditional herb, not a treatment. Research on mullein in people is limited. If you have a cough that lasts more than a few weeks, wheezing or shortness of breath, see a doctor rather than relying on any supplement.

Mullein is a widely used traditional herb, but research in people is limited. Check with a doctor if you are pregnant, nursing or take medicine.
Labels generally list botanicals from largest to smallest, so mullein is the first-listed plant.
