What the Research Says
Research on common mullein is promising but often limited to animal or test-tube studies. A 2021 study in BMC Complementary Medicine and Therapies confirmed its role in wound healing, while a 2005 Phytotherapy Research study supported its expectorant and bronchodilatory effects in animals. Its antibacterial and antiviral properties were noted in a 2002 Journal of Ethnopharmacology study and a 2023 Healthline report, respectively. However, human studies are scarce, and the FDA does not regulate herbal supplements for safety or efficacy, per Healthline. Consult a healthcare provider before use, especially for chronic conditions, to ensure it complements your health plan.
Tips for Harvesting and Sourcing Mullein
To get the most from common mullein, follow these guidelines:
