Mullein (Verbascum thapsus) has a long history of traditional use for various respiratory and throat-related ailments, including sore throats and inflammation, which are often associated with tonsillitis. Traditional herbalists have used mullein leaves and flowers in infusions, teas, and syrups to soothe irritated mucous membranes and reduce discomfort in the throat. The demulcent and mild anti-inflammatory properties attributed to mullein are thought to help ease the swelling and irritation connected to tonsil issues, though these uses are based primarily on folklore and herbal tradition rather than rigorous clinical research.

From a scientific standpoint, there is limited evidence directly investigating mullein’s effects on the tonsils specifically. Some in vitro and animal studies suggest that mullein extracts possess mild anti-inflammatory, antimicrobial, and soothing actions, which could theoretically benefit throat and tonsil health. However, clinical trials focusing specifically on tonsillitis or tonsil health in humans are lacking. Most of the available literature and monographs reference its general use for upper respiratory tract support rather than tonsils alone.

In summary, the use of mullein to support the tonsils is justified by traditional herbal practices and anecdotal evidence, but direct scientific validation for this specific use is limited. The evidence rating is moderate for tradition but low for clinical proof.
