People have used mullein (Verbascum thapsus) for centuries to soothe respiratory discomfort. Leaf extract provides a concentrated, standardized dose of the plant's beneficial compounds, and it is easier to take than loose herb or tea.
The extract acts as a mild expectorant and demulcent. This combination helps loosen mucus and soothe irritated mucous membranes, calming coughs and easing chest congestion.
You can take the extract in capsule or liquid form, with or without food. Because potency varies between products, follow the label directions for your specific bottle.
Mullein is usually safe for most people, but no rigorous studies have examined its safety during pregnancy or breastfeeding. If you have a chronic respiratory condition or take other medications, talk to a healthcare provider before using mullein.
