What is mullein?

Scientific name for mullein is Verbascum thapsus (great mullein or common mullein) and it is originally native to Asia, North Africa and Europe and was gradually introduced in Australia and America (1).

Verbascum thapsus has broad native origins from North Africa, Asia and Europe to East to Western China, British Isles, Scandinavia, Siberia and Southern Himalayas. In Northern Europe, it grows from sea level up to an altitude of 1,850 meters and in Western China it grows at 1,400–3,200 m altitude.

History and namesake

Mullein or Verbascum thapsus, is a tall and stoic plant, sometimes reaching a height of up to ten feet.

Its conventional name mullein is extracted from the Middle English word moleyn, which means soft. Verbascum is a modification of the Latin word barbascum, which means bearded. This was due to its furry foliage. The Greeks had their own name for mullein in ancient times. They called it fluma and flego, meaning “to set fire.” Its leaves were dried and rolled, used in oil lamps as wicks, and its stalks were used at funerals.

Settlers brought mullein in Europe for medicinal herb gardens in early 1600’s. By the 1800’s use of mullein had spread from east coast to west.

The Native American Indians found mullein to be very useful as a medicinal plant. European settlers initially introduced the plant to them. But the Indians also used its root for its medicinal properties.

Native tribes used mullein leaf tea for treating inflammation, colds and rheumatism. It was considered to be anti-inflammatory, antispasmodic, analgesic and expectorant. Its demulcent and astringent properties were found to be useful in treating diarrhea. The root was dried and made into teething charms for infants and children. It was used to prepare sweet tea for coughs and persistent swelling of larynx. An infusion of the root was used to treat renal troubles, and a leg bath was made if there was ever water retention in the lower body. Extracts and herbal tea made from infused root were also used to treat infections and athlete’s foot. To reduce swelling and relieve pain, mullein leaf poultices were applied externally to sprains, bruises, and rheumatic pains. And a leaf well soaked in warm water was applied to swollen glands.

Dried mullein leaves were smoked for curing respiratory disorders. Leaves were dried, rolled and smoked for management of bronchitis, asthma and tuberculosis. It was found to relieve cough, and alleviate discomfort, pain and inflammation associated with these respiratory disorders.

Mullein leaf was a popular choice in spiritual healing rituals as well, and was burned or smoked together with other plants. The Hopi used mullein leaves in cures for fits of mania, and those who were mentally unstable.

Structure of mullein

It is a plant of biennial nature and hairy form that can grow up to three meters tall or more. It has small yellow flowers that are thickly clustered on a tall stem, which appear from within a large group of leaves. It is found in a varied range of habitats, but is more largely distributed in places which receive plenty of sunshine and it emerges from toughened persistent seeds in the soil seed bank. It is a widespread weedy plant that germinates by prolifically producing seeds. Its seeds require open ground to germinate therefore its reproduction is not aggressively invasive.  It also gives home to many insects, many of which can be detrimental to other plants. Even though they are easy to terminate one by one by hand, large populations are difficult to abolish permanently.

This is how mullein looks like:

It is mostly used for herbal remedies, with well-known emollient and astringent properties. Mullein remedies are especially useful for coughs and related problems, but also used in topical applications against a variety of skin problems. Mullein has also been used to make dyes and torches.

Health benefits of mullein tea

Benefits of drinking mullein leaf tea are as follows:

Treatment of tuberculosis

Mullein leaf extract was used as a treatment for tuberculosis in Europe as early as the 16th century. A study in the 18th century found that mullein relieved the symptoms of several tuberculosis patients at St. Vincent’s hospital in Birmingham, England. It was widely believed that if mullein was used in initial stages of the disease, it could bring about a full recovery.

Today, scientific experiments and medical studies have shown that mullein has expectorant and anti-bacterial properties, both of which are needed in treating this respiratory disorder. Although its effects against mycobacteria, the bacteria that causes tuberculosis, have not been studied extensively, it has been studied against other bacteria with positive outcome and great success and other plants belonging to same species as mullein have been specifically studied against mycobacteria with success (2, 3).

More research is required but the benefits of mullein as a natural treatment for TB is promising as can be gleaned from historical evidence and modern studies.

Treatment of cold and flu

As discussed before, mullein leaf extract has expectorant and anti-bacterial properties, which makes mullein tea a great home remedy if you have flu or a cold with lots of congestion. According to medical researchers, the saponins present in mullein give it its expectorant properties (4, 5). Mullein also helps to reduce the amount of mucus produced in body and reduces congestion.

Treatment of asthma, allergies and bronchitis

Mullein tea is an effective remedy for treatment of bronchitis, asthma and allergies due to the same factors that it is helpful against tuberculosis, flu and cold – it is a natural expectorant, anti-inflammatory, antibiotic and reduces congestion (6).

Mullein is regarded beneficial primarily for respiratory ailments, and while its applications are actually much wider than that, it definitely is exceptional in its healing and protection of respiratory disorders and breathing problems.  For cure of pulmonary disturbances primarily the leaf is used. Its use is indicated whenever patient has a tight yet wheezy hacking cough, particularly where the wheezy cough tends to appear and disappear, indicating constrictions beginning to become chronic.

Mullein tea is doubly indicated where there is dryness of respiratory tract leading to blockage of productive expectoration, and it is usually combined with Mallow root for treatment of this problem. Researcher Jim McDonald elaborates a bit on Mullein’s usefulness in dry coughs:

“Mullein leaves are the most often used part of the plant, and among the first plant remedies to be regarded effective for treating dry coughs and congestion, as they are brilliant as an expectorant. An expectorant facilitates lungs in expelling phlegm and mucous by loosening it from the walls of  lungs and allowing it to be expelled through being coughed up; therefore, Mullein will stimulate coughing, even though that is the symptom being treated. What Mullein is really doing is helping out the body’s natural reaction to congestion – coughing – to be more effectual.”

It is not only an expectorant and soothing, but it also helps prevent infections from spreading and settling into the delicate tissue of respiratory system. This makes it brilliant in a large assortment of respiratory disorders, wherever there is constriction or dryness, including multiple cases of bronchitis, asthma and other chronic respiratory disease or distress. Matthew Wood observed that in several cases where this remedy is appropriate, there will be concomitant pulmonary and renal weakness.

The flowers and leaves of mullein are useful when used in many chest infusions, and even though it does not have the medicinal penetrating volatile oils of the typically used mint, eucalyptus and so on, the aromatics of those herbs combine well with Mullein tea and seem to transmit its lung healing effect much further into the body.

Anti-inflammatory effects

Mullein tea is a natural anti-inflammatory owing to the verbascoside present in it. Verbascoside is caffeic acid sugar ester and phenylethanoid (7).

Anti-bacterial effects

Mullein contains naturally occurring anti-bacterial properties. Mullein's anti-bacterial traits make it useful in treating infections.

It has been used to treat tuberculosis as it inhibits growth of mycobacterium, the bacteria which are the culprit behind this disease. This is due to the verbascosides it contains. Medical studies have found that verbascoside works exceptionally well against Staph infections (8).

In treating digestive disorders

Drinking mullein has been found useful in curing a wide array of digestive problems such as constipation, hemorrhoids, diarrhea and bladder infections. It is occasionally also used to get rid of intestinal worms (9).

Cramps

Mullein tea has anti-spasmodic traits that help relieves stomach cramps or menstrual cramps linked with gastric distress (9).

Sedative properties

Skin soothing

Application of dried mullein tea to irritated areas of skin may help you achieve relief from the discomfort allied with conditions such as a burn, rash, blisters or cuts. Because mullein is anti-inflammatory and antibacterial, it will also help relieve any skin conditions caused by inflammation or bacteria.

Relief of joint pain

Mullein tea has anti-inflammatory effects which help in easing the pain associated with muscular or joint pain by decreasing swelling and inflammation (11).

Expectorant properties

According to a research article published in "Evidence-Based Complementary and Alternative Medicine" in 2010, tea prepared from mullein leaves is conventionally used as an expectorant because it helps drive out mucus from the chest. The anti-rheumatic and expectorant properties of mullein tea cause patient to cough and expel mucus from lungs and throat. It also lubricates your respiratory surfaces while reducing swelling, which relieves irritation (12).

The seeds of mullein have high rotenone content. It is a potentially harmful and toxic substance which can cause adverse effects if it is ingested, especially if these seeds are used on a daily or regular basis. Studies according to the PAN Pesticides Database show that intake of rotenone can induce abdominal cramps, diarrhea, convulsions or vomiting. Therefore, it is essential to ensure that there are no seeds on the mullein plant flowers before using them for preparation of mullein tea. Women who expecting or breastfeeding should avoid drinking tea prepared from mullein leaves or flowers on a regular basis due to its potential harmful effects.

Skin irritation

In general, mullein leaf tea is a safe herbal brew for individuals to drink on a regular basis. But some studies have shown that frequent use of mullein can lead to skin irritation. Using the mullein herb in the form of liquid extract or brew as a topical application can cause skin rash, redness or other severe skin problems.

They strained the tea through a piece of cheese- cloth before consumption to remove any mullein leaf hairs, which could irritate their throat.
