This site states this specific figure directly: Mullein Leaf Extract (10:1).
This site's own ingredients post explains it directly: the extract is concentrated ten times over the raw leaf, so a small dose delivers more of the active compounds — worth reading this as a potency specification, not just a bare ingredient name.
Worth confirming your own bottle's Supplement Facts panel states this same 10:1 ratio specifically, as one concrete way to verify the formula matches what this site describes.
