Mullein Leaf Extract: the tall, velvety herb
A plain-language look at one of the three botanicals in BreathiZen.*

Mullein is a tall biennial plant with soft, felt-like leaves and a spike of small yellow flowers. It grows wild along roadsides and meadows across Europe, Asia and North America, and its Latin name is Verbascum thapsus.
People have kept mullein in herbal traditions for centuries, which is why it is a familiar name in respiratory wellness products. BreathiZen lists mullein leaf extract first, as a 10:1 extract, and it leads the blend.*
