In episode 89 of Mother Earth News and Friends, Joanne Bauman discusses how to use mullein (Verbascum thapsus), how to make a mullein tincture, and how to use the herb for medical issues.

Harvesting Mullein Flowers and Leaves

Some people have said they aren’t sure how to pronounce mullein. … It’s like “mull,” as in mulling over mullein. Because mullein is a biennial plant (taking two years to complete its life cycle), leaves and roots can be harvested at the end of the first and beginning of the second year, while flowers can only be harvested from the second year.

Make fresh plant preparations or dry for later uses.

Harvest mullein leaves when they’re fresh and vibrant-looking, ideally when the leaves are still in a basal rosette. The best times are in the fall of the first year’s growth or in the spring of the second year before the flower stalk starts to grow. In a pinch, the leaves can be harvested from a plant with a flower stalk. When foraging for mullein leaves, take a few from a single plant, leaving plenty to ensure the continued life of the plant.

You can dry mullein leaves by cutting an entire stalk and hanging it upside down out of the direct sun to dry. I pick mullein leaves as the basal rosette grows and also from second-year mullein when they’re fresh and soft and green. I lay them out in a single layer on a large flat dying basket so air can circulate, and I slide the basket under a bed to keep out of direct sunlight. In a day, I check them and turn them over, then do this again in a few days. Depending on moisture and humidity, the leaves will typically dry in days to a week. They’ll be less soft and pliable and more dry to crumble. I know an herbalist who lays hers out on a paper sack or basket and uses her car trunk to dry leaves. It typically only takes around a few hours on a good sunny, warm day.

Mullein Benefits for Lungs and Throat

Mullein leaves are an excellent tonic for the entire respiratory system: the sore throat irritation and lung problems, such as cough, congestion, bronchitis, etc.  2 to 4 cups of mullein leaf infusion daily also can strengthen the lungs, or restore health to lung tissues after “assaults,” such as tobacco smoke or radiation. Mullein helps relieve allergies and asthma as well. Mullein leaves are fuzzy, so use a muslin bag for making your infusions or strain through tightly woven cloth (cheesecloth or even a coffee filter).  Small hairs on mullein leaf may cause irritation in the mouth and throat if not filtered out of extracts prior to consumption.

Drink warm or cool according to preference.  In addition, a compress made from plant strained from the infusion can be applied to the chest to ease congestion. A warm poultice of the leaf can be applied to sprains, painful joints, and swollen glands.

How to Use Mullein “Tea” Infusions

Making nourishing herbal infusions is simple, affordable, taste great, and are an excellent source of absorbable vitamins and minerals. Nutritive herbs were meant to be consumed on a regular basis as a part of our food. They were intended to help nourish our bodies and keep them strong. These nutrients found behind the cell wall of the plant, release themselves only after steeping dried (drying makes the cell wall more fragile) plant material for 4 to 8 hours. My favorite herbs for infusion are nettle leaf, oatstraw, linden blossom/leaf, violet leaf, raspberry leaf, calendula blossom, and mullein or marshmallow root (althea) in winter, but only one at a time. You can add a bit of honey or mint to infusions if desired.

An herb “tea” isn’t brewed very long. An infusion is a large amount of herb brewed for a long time to free up the vitamins and minerals. Typically, one ounce by weight (about a cup by volume) of dried herb is placed in a quart jar which is then filled to the top with boiling water, tightly lidded and allowed to steep for 4 to 8 hours. Use muslin bags for ease; strain the plant matter out (please return it to the ground, not the trash). After straining, a cup or more is consumed, and the remainder chilled to slow spoilage. Drinking 2 to 3 cups a day is usual. You can start out slowly with 1 to 2 cups. Since the minerals and other phytochemicals in nourishing herbs are made more accessible by drying, dried herbs are considered best for infusions.

You can make infusions at night before bed and they are ready in the morning. You can drink infusions either hot or cold/iced. You can mix part infusion, with your drinking water initially if you want to, rather than drink full strength. You can also add infusion to soups, stews, etc. as a liquid (if recipe calls for 2 cups of water, use 1 cup infusion, 1 cup water, etc.). You can freeze infusion in ice cube trays and use it in cooking that way also. I even know one woman who made morning coffee with water and part oatstraw infusion so her husband could get the benefits and not even know he was having his coffee made with it!

Drink the quart of infusion within 36 to 48 hours typically, or until it clouds or smells off (you’ll know). You can use any you do not use to water house plants–they will love the nutrients!

How to Use Mullein Flower Oil

Mullein oil is best known for use in easing ear infection and pain or swimmer’s ear.

Instructions

  1. Find stalks of mullein in flower, and pick the flowers that are just out. Do not wash any part of the plant. Moisture can ruin your oil.  You can put flowers in a small basket and let them wilt an hour or so to reduce moisture content.
  2. Put the mullein flowers in a small jar and fill to nearly the top with extra virgin olive oil.  You’ll need more flowers to fill the jar and they don’t bloom at once, but sporadically, so gather more flowers over the next few days and add them into the oil.
  3. Lid, and label and keep the jar at normal room temperature out of direct sunlight and not refrigerated.
  4. Any condensation can cause moisture which causes oil to get moldy and spoil. Store in a cupboard or on a shelf. I like to add a couple of chopped garlic cloves to my oil. Garlic is antibacterial and antiviral. In 6 weeks, strain off (decant) the liquid and return the plant to the earth or compost.

You can apply 1 to 2 drops in an ear with a dropper. Massage the ear. Do not apply if there is any chance or you suspect perforation of the eardrum.

As for how to use mullein flower oil in salves, beeswax is usually added to thicken oils.

This mullein flower oil can also be useful for mouth and gum sores; rashes, bruises, cuts, and sores. It’s also beneficial for sprains and inflamed joints. Mullein flower oil can be used postpartum to heal the perineum.

Mullein Tincture Recipe

  1. Remove the fresh herb off of the stalks — flowers, as they bloom, leaves fresh and green any time off rosettes or stalk. If using freshly dug roots early spring or fall (the first year for roots), wash and scrub them of dirt.
  2. Chop fresh herbs and grind dried herbs to increase the surface area for the maceration. Place herbs into a clean, dry jar with a wide mouth.
  3. Pour high proof alcohol (vodka or brandy) over the herbs until they are completely covered. Dry herbs may absorb the liquid, so check and add alcohol as needed.
  4. Cover tightly with a lid and place the jar in a dark cupboard and allow it to soak or macerate for 6 weeks.
  5. During this time period, give the jar a shake every 2 to 3 days. Keep an eye on the alcohol level to ensure all your herbs are still covered.
  6. After 6 weeks, strain the mixture through a strainer or cheesecloth and press down on herbs to squeeze out any remaining liquid.
  7. Use a funnel to transfer into labeled, glass bottles and store out of the light.
