Mullein (Verbascum thapsus) is a flowering plant with a long history of use in traditional herbalism, particularly for respiratory comfort. Research suggests that its leaves and flowers contain saponins, flavonoids, and mucilage compounds that may help soothe irritated airways and support normal respiratory function. Studies indicate that mullein preparations, especially when combined with other herbs, have shown promising results for easing occasional coughs and supporting ear comfort, with mullein-infused ear oil being one of the more widely recognized traditional applications. While clinical research is still evolving, preliminary findings point to notable anti-inflammatory and demulcent properties that make mullein a subject of growing scientific interest. It is most commonly enjoyed as a gentle tea or used topically as an herbal ear oil.
