Mullein is a tall, soft-leaved plant, and its leaf is the first ingredient named in the BreathiZen blend.
What it is
Mullein (Verbascum thapsus) is a plant with big, fuzzy, gray-green leaves and a tall spike of small yellow flowers. The leaf is the part used in BreathiZen. The label calls it a 10:1 extract, which means about ten parts of leaf go into making one part of extract.
Where it comes from
Mullein grows wild along roadsides and in open fields across many parts of the world. People have gathered its leaves for a very long time and often brewed them as a warm tea. Today, the leaf is dried and turned into a concentrated extract for products like this one.

Why it is in BreathiZen
The brand lists mullein leaf extract first in its 154 mg proprietary blend and ties the formula to healthy airways and everyday breathing comfort.* Because the label shows one total for the whole blend, you will not find a separate amount for mullein.
How it fits your day
You do not have to brew anything. The extract is already in the spray, so your routine stays at four pumps once a day. Next, read about ginger root and lemon extract, or see all three on the label guide.
