What Is Mullein Tea?
Mullein tea is an herbal infusion made from the dried leaves, flowers, or roots of the mullein plant (Verbascum thapsus). Often called “flannel leaf” due to its velvety texture, this biennial plant grows wild in fields, roadsides, and disturbed soils across temperate regions. The parts used in tea are typically harvested in the plant’s first year (for leaves) or second year (for flowers), then dried and steeped in hot water.
Unlike black or green tea, mullein contains no caffeine, making it ideal for evening sipping or for those sensitive to stimulants. Its flavor is mild, slightly earthy, and often described as smooth—especially when strained well. Because the tiny hairs on mullein leaves can irritate the throat if not filtered out, proper preparation is key to enjoying a pleasant, soothing cup.
Top Benefits of Mullein Tea for Respiratory Health
One of the most celebrated uses of mullein tea is its ability to support healthy respiratory function. Thanks to its combination of mucilage, saponins, and anti-inflammatory compounds, it acts as a natural expectorant and demulcent.
Loosens Mucus and Eases Coughs
Mullein helps break up and expel mucus from the lungs and bronchial tubes. This makes it especially helpful during colds, flu, or chronic conditions like bronchitis. The saponins in mullein have a mild expectorant effect, encouraging the body to cough up phlegm more easily—so you can breathe freer and sleep better.
Soothes Irritated Airways
The mucilage in mullein forms a protective, soothing layer over inflamed tissues in the throat and lungs. Think of it like a warm blanket for your airways. This demulcent action can ease dry, hacking coughs and reduce throat irritation caused by allergies or pollution.
May Help with Asthma and Allergies
While not a replacement for medical treatment, mullein tea’s anti-inflammatory properties may help reduce airway constriction and ease mild asthma symptoms. Some users report fewer nighttime coughing fits and improved breathing after regular use during allergy season.
Beyond the Lungs: Other Health Benefits
Mullein tea isn’t just for your chest—it offers a range of additional wellness perks.
Supports Ear Health
Traditionally, mullein flower oil has been used in ear drops to relieve earaches and mild infections. While drinking the tea won’t directly treat ear issues, the anti-inflammatory and antimicrobial properties may support overall ear and sinus health. Always consult a healthcare provider before using any remedy for ear problems.
Promotes Skin Healing
Applied topically as a poultice or infused oil, mullein can help soothe minor burns, cuts, and skin irritations. Drinking the tea may also support internal healing by reducing systemic inflammation.
Aids Digestion and Relaxation
Though less commonly discussed, mullein has mild diuretic and calming effects. Some people find it helpful for easing digestive discomfort and promoting relaxation before bed—making it a great evening tea option.
How to Make Mullein Tea at Home
Brewing mullein tea is simple, but a few tips ensure the best taste and safety.
Choosing Your Ingredients
Use high-quality, organic dried mullein leaves or flowers. Avoid wild-harvested mullein from roadsides or polluted areas, as it may absorb toxins.
Step-by-Step Brewing Guide
- Boil 1 cup (8 oz) of water.
- Add 1–2 teaspoons of dried mullein leaves or flowers to a tea infuser or muslin bag.
- Steep for 10–15 minutes. Longer steeping extracts more mucilage for a thicker, more soothing brew.
- Strain thoroughly through a fine-mesh sieve or coffee filter to remove tiny hairs.
- Optional: Add honey, lemon, or a pinch of ginger for flavor and extra soothing power.
Safety Tips
Never drink unstrained mullein tea—the fine hairs can irritate your throat. If you’re pregnant, nursing, or on medication, talk to your doctor before use. Start with small amounts to test tolerance.
Who Should Try Mullein Tea?
Mullein tea is a great fit for anyone looking to support their respiratory system naturally. It’s especially useful for:
- People with frequent colds or seasonal allergies

It’s also popular among herbalists, natural health practitioners, and folks who prefer plant-based remedies over over-the-counter syrups.
Potential Side Effects and Precautions
Mullein tea is generally safe when prepared correctly. However, a few precautions are worth noting:
- Throat Irritation: Always strain the tea thoroughly. The tiny hairs on the leaves can cause discomfort if ingested.
- Allergic Reactions: Rare, but possible. Discontinue use if you experience itching, swelling, or difficulty breathing.
- Drug Interactions: Mullein may affect how the body absorbs certain medications. Consult your doctor if you’re on diuretics, diabetes meds, or lithium.
- Pregnancy and Breastfeeding: Limited research exists, so it’s best to avoid unless approved by a healthcare provider.
When in doubt, start slow and listen to your body.
