What is Mullein?
Mullein is a biennial herbaceous plant that grows tall yellow flowers on a single sturdy stalk the second year after planting. It is part of the figwort family (Scrophulariaceae) and native to Europe, Africa and temperate Asia but now grows wild in many parts of the world including the US.
Uses of Mullein
Both the dried mullein leaves and flowers have a long history of uses including:
- Treating respiratory issues like coughs, colds, and bronchitis symptoms
- Easing inflammation related to arthritis, nerve pain, urinary tract infections, and hemorrhoids
- Supporting ear health due to natural antibiotic and anti-inflammatory abilities
- Repelling insects when applied topically
Forms of Mullein
Dried mullein leaves are most commonly used to make therapeutic teas, tinctures and extracts. The large furry leaves are typically harvested just before the plant flowers in summer, then dried whole or powdered before use.
Mullein flowers and roots can also be utilized, but the leaves contain the widest variety of nutrients and plant compounds responsible for most health benefits that this common weed provides.
Benefits and Uses of Mullein Leaf
For centuries people have turned to versatile mullein leaf for natural relief from respiratory congestion, swollen lymph nodes, sore throats, headaches and various inflammatory conditions without major side effects. Science is now confirming many of its traditional uses.
Soothes Cough and Congestion
Mullein leaf has the ability to help expel excess mucus from the respiratory tract and reduce swelling making it an excellent natural remedy for coughs, colds, hoarseness and bronchitis. Both the plant compounds and soothing effect on membranes brings relief.
Ear Pain and Infection Fighter
The anti-inflammatory and antimicrobial properties of mullein leaf extracts have been shown to reduce ear pain and fight infections when applied externally around the ear canal as a natural remedy for middle ear issues in both children and adults.
Anti-Inflammatory Actions
Compounds in mullein leaves called flavonoids reduce inflammation at a cellular level to help symptomatic relief of arthritis, gout, headaches, UTI discomfort, hemorrhoid inflammation and nerve pain when taken regularly as a tea, tincture or herbal extract.
Supports Bladder Control
Mullein leaf has mild diuretic action to gently increase urine flow. This helps flush bacteria from the urinary tract to prevent recurring infections and reduce incontinence issues related to bladder wall inflammation for both men and women.
Skin Soothing
Both the antibacterial and tissue healing properties of mullein leaf can provide relief when applied externally to minor cuts, burns, eczema patches and insect bites. As an infused oil or poultice, it protects skin integrity to promote faster healing.
Scientific Evidence of Mullein Benefits
While human evidence remains limited regarding dried mullein leaves, various laboratory tests and animal research studies support the following potential health benefits:
- Antimicrobial activity against certain bacteria and fungi like Aspergillus niger and Escherichia coli
- Analgesic pain-relieving effects comparable non-steroidal anti-inflammatory drugs
- Anticancer actions against human lung, cervical and colon cancer cells lines in vitro
- Antiviral capabilities including against herpes viruses
- Antioxidant protection to minimize oxidative stress in tissues
- Anti-diabetic and neuroprotective qualities
Further investigation around the best extraction methods, dosing, long term use and ability to enhance delivery to bodily tissues is still needed through expanded trials and next level research.
Possible Side Effects and Safety
There are very few reasons why mullein leaf would be unsafe when used properly. However, as with most herbal supplements, side effects can still occur in some cases.
Most Common Potential Risks
- Skin irritation - test topical preparations first before applying liberally
- Allergic reactions - seek medical care if hives, swelling or breathing issues occur
- Upset stomach when ingested - start slowly with small doses
- Dizziness or constipation from dehydration due to the mild diuretic effect
Safety Precautions
To be on the safe side, the following groups should exercise more caution with mullein leaf use:
- Pregnant or breastfeeding women
- Children and elderly patients
- Those with diabetes or taking prescription medications - potential interactions can occur so check with your pharmacist
Speak to your doctor before use if you have any preexisting health conditions or concerns about potential contraindications with mullein supplementation.
How to Take Mullein Leaf
Most commonly, dried mullein leaves are used to make a traditional medicinal tea or infused in oil for topical applications. But leaves can also be incorporated into tinctures, extracts, tablets and formulations blended with other herbs.
Mullein Leaf Tea
Add 1-2 teaspoons of dried mullein leaves per cup of hot water and steep for at least 10 minutes for maximum extraction of plant compounds. Strain the leaves then drink up to 3 cups daily for issues like coughs, bladder infections and inflammation.
Mullein Leaf Oil
Infuse mullein flowers or leaves covered in olive oil or coconut oil and allow to steep for several weeks before straining and transferring to a sealed container. For ear pain or ear infection symptoms, lightly warm the strained oil before placing a few drops into the impacted ear canal.
This same oil infusion can be used to treat skin irritations by dabbing small amounts onto affected areas after first testing skin sensitivity.
The Bottom Line on Mullein Leaf
Dried mullein leaves certainly deserve their long-standing reputation as an effective medicinal plant. With proven antibacterial, antiviral and anti-inflammatory properties combined with a solid safety profile, mullein leaf can reduce swelling and provides symptomatic relief for respiratory congestion, ear infections, arthritis stiffness, UTI discomfort and hemorrhoid inflammation.
While human evidence remains limited, the antimicrobial, analgesic, antioxidant and anticancer actions demonstrated in lab tests support the continued study and use of mullein leaf and flower extracts as herbal complementary therapy options and potentially as purified drug compounds.
