Source of validity: Traditional
Rating (out of 5): 2

Mullein (Verbascum thapsus) has a long history of traditional use in herbal medicine, particularly for supporting respiratory health. Traditional healers have used mullein leaves and flowers to prepare teas, tinctures, and syrups intended to soothe the respiratory tract, address coughs, and ease symptoms related to bronchitis, asthma, and upper respiratory allergies. The demulcent and mild expectorant properties attributed to mullein are believed to help reduce irritation of mucous membranes and facilitate the expulsion of mucus, which may indirectly offer relief from some allergy symptoms affecting the respiratory system.

Scientific validation for mullein’s effectiveness specifically in treating or supporting respiratory allergies is limited. While some laboratory and animal studies have indicated that mullein extracts possess anti-inflammatory and antioxidant properties, few clinical trials have directly assessed its impact on allergic respiratory conditions in humans. The bulk of evidence supporting mullein’s use for allergies comes from historical and ethnobotanical sources rather than rigorous scientific studies. Thus, while mullein continues to be included in herbal formulas for respiratory wellness, its use for allergies rests primarily on tradition with modest supportive evidence from preliminary pharmacological research. Individuals interested in using mullein for respiratory allergies should consult healthcare professionals, especially if they are also taking other medications or have underlying health conditions.
