Mullein (Verbascum thapsus) has a long history of traditional use to support the respiratory tract, including the throat and vocal cords. Folk herbalists have used mullein leaf, flower, and sometimes root in teas, syrups, and lozenges for soothing sore throats, coughs, and hoarseness—symptoms that can affect the vocal cords. The demulcent (soothing, mucilage-rich) properties of mullein are cited as helpful for irritation in the throat and upper respiratory passages. Historic texts and herbal manuals from Europe and North America commonly recommend mullein for singers and speakers experiencing vocal strain.

However, while there is a strong tradition of use, scientific evidence supporting mullein’s effectiveness specifically for vocal cord health is limited. Most research has focused on its anti-inflammatory and antimicrobial properties in general respiratory conditions, rather than targeted studies on vocal cord function or pathology. Some in vitro and animal studies suggest mullein extracts may inhibit certain bacteria and reduce inflammation, which could theoretically benefit irritated throats. Yet, there are no robust clinical trials confirming its direct efficacy for vocal cord support in humans.

In summary, mullein’s use for the vocal cords is primarily based on traditional herbal practices and anecdotal reports. Scientific validation is minimal, and evidence remains largely circumstantial or extrapolated from its general use for respiratory and throat ailments.
