Mullein Tea: A Complete Guide to Respiratory Support

Mullein (Verbascum thapsus L.), also known by charming folk names like Bunny's Ears, Donkey's Ears, and Velvet Plant, is one of the oldest respiratory herbs on record. The first documented medicinal use of Mullein dates back nearly 2,000 years to the Greek physician Dioscorides, who recommended it for pulmonary conditions. Since then, it has been a trusted botanical across European, Turkish, and Native American healing traditions.

When we talk about Mullein tea, we're talking about a demulcent herbal infusion — one whose high mucilage content absorbs water and becomes slippery, helping to lubricate and soothe the respiratory system. The mild saponins in Mullein further support this action by promoting the loosening and expulsion of mucus, making coughs more productive. Whether you prefer a classic steeped infusion or the convenience of capsules, Mullein offers the same time-tested respiratory nourishment.

A typical Mullein tea preparation uses 1–2 teaspoons of cut-and-sifted Mullein leaf per 8 oz of hot water, steeped for 10–15 minutes. It's important to strain very well through a fine mesh or cheesecloth to remove the tiny leaf hairs, which can cause throat irritation if ingested. For those who want the benefits of Mullein without the brewing process, Nature's Sunshine offers Mullein leaf in convenient 290 mg capsules — the same herb, just in a different form.

Mullein tea's respiratory benefits come from a team of bioactive compounds working together. The mucilaginous polysaccharides form a soothing, protective layer on irritated mucous membranes — the primary mechanism behind Mullein's demulcent properties. This coating helps reduce friction and calm inflamed tissue throughout the airways.

Saponins act as natural expectorants by reducing surface tension within the airways, facilitating the loosening and movement of mucus. Both the leaves and flowers contain these compounds, which make coughs more productive and help clear bronchial congestion.

Flavonoids such as quercetin and rutin are antioxidants that may help protect lung tissue from oxidative stress. A 2021 PMC review confirmed that anti-inflammatory phytochemicals in Mullein, particularly quercetin, correlate with its traditional respiratory uses. In silico research has also shown affinity between Mullein's flavones and pro-inflammatory cytokines implicated in respiratory inflammation.

Verbascoside (also known as acteoside), a polyphenolic compound first isolated from a Verbascum species, has demonstrated antioxidant, anti-inflammatory, and antimicrobial properties in laboratory research. Iridoid glycosides such as aucubin have also been reported to have anti-inflammatory and antimicrobial effects. Together, these constituents provide a plausible scientific foundation for why Mullein tea has remained a go-to respiratory herb for centuries.

Mullein tea and Mullein supplements are traditionally suited for anyone seeking gentle, natural respiratory support. If you experience occasional bronchial congestion, seasonal respiratory discomfort, or simply want to nourish your lungs, Mullein is a time-honored choice.

Those dealing with occasional coughs and sore throats may appreciate Mullein's demulcent mucilage, which has been traditionally used to coat and soothe irritated throat and airway tissues. People navigating cold and flu season have historically turned to Mullein tea for its expectorant and soothing qualities.

If you're looking for support during seasonal allergy challenges, Mullein has been traditionally used for hay fever and allergic respiratory complaints, attributed to its antihistamine and anti-inflammatory constituents. Those who want everyday lung and bronchial nourishment — such as individuals concerned about upper respiratory wellness — may also benefit.

This Nature's Sunshine formula is vegan, kosher, halal, and non-GMO, making it accessible to a wide range of dietary preferences. If you're not sure whether Mullein is right for your situation, our naturopath is available for a free consultation to help you explore your options.

Important: Expectant women and those breastfeeding should avoid using Mullein tea, as safety data for these populations is lacking. Oral use of Mullein is not recommended for children. Individuals with severe liver or kidney conditions should exercise caution, and those on anticoagulant or immunosuppressant medications should consult a healthcare provider first. Anyone with a known allergy to Mullein or the Scrophulariaceae family should avoid its use.

Take 2 capsules with a meal twice daily.

Each serving of 2 capsules provides 580 mg of Mullein leaf. The bottle contains 100 capsules. For those who prefer the traditional infusion experience, a classic Mullein tea can be prepared by steeping 1–2 teaspoons of cut-and-sifted leaf in 8 oz of hot water for 10–15 minutes, then straining thoroughly through fine mesh or cheesecloth to remove the tiny leaf hairs that can irritate the throat.

Mullein is traditionally used for short-to-medium-term support — for example, during a period of respiratory discomfort or seasonal challenges. There is no widely established safety data on continuous, long-term daily use. If you have questions about how Mullein fits into your wellness routine, our naturopath offers free consultations and is happy to help.
