Mullein

No controlled human trials of mullein for lungs, cough or asthma were located. Two trials in children with ear infections tested herbal ear drops that combine mullein with garlic, calendula and St. John's wort. Ear pain fell in every group, mostly with time, and the drops matched anesthetic drops. No side effects were documented.

What people take it for, and what was found

Mixed results1

LimitedStudied in children

Ear pain from middle ear infection

Small trials found herbal ear drops with mullein eased children's ear infection pain as much as anesthetic drops, but most pain resolved with time.

The numbers and sources
Effect
In 103 children aged 6 to 18 with ear pain from acute otitis media, herbal ear drops containing garlic, mullein, calendula and St. John's wort in olive oil reduced pain over 3 days as much as anesthetic ear drops [1]. In 171 children aged 5 to 18, the same herbal mix with lavender and vitamin E, alone or with other treatments, improved pain in every group over 3 days. The authors found that about 80% of the pain was self-limited and explained by time, and the group with the largest treatment effect explained 7.3% of total pain reduction [2].
Population
Children with acute otitis media [1][2].
Sources
[1], [2]
Caveats
Both trials tested combination ear drops, not mullein alone, and neither had a placebo group. Both were run by the same research group [1][2].

Claimed, not studied in people1

Untested

Lung health, cough and asthma

Not studied in people. The EU medicines agency lists mullein flower tea as a traditional herbal medicine for sore throat with dry cough and cold, based on long-standing use.

No study in people. This rests on documented traditional use.

The numbers and sources
Effect
The European Union herbal monograph adopted by the European Medicines Agency's herbal committee in 2018 lists mullein flower, as a tea taken by mouth, as a traditional herbal medicinal product used to relieve symptoms of sore throat associated with dry cough and cold. It states the indication rests exclusively on long-standing use, and gives no well-established use indication [3].
Population
Traditional use in Europe, as reviewed by the European Medicines Agency [3].
Sources
[3]
Caveats
Traditional use is a record of how long people have used it, not a test of its effect. The monograph covers sore throat with dry cough and cold only, not asthma, bronchitis or lung health. No controlled trial in people was located.

Doses studied

The ear trial used 5 drops of the combination herbal oil three times a day [2]. No human dosing evidence was located for mullein taken by mouth.

Risks

Checked, no increase found1

Side effects in trials

The numbers and sources
Effect

Population
Children with acute otitis media [2].

Caveats
One small trial of a combination product applied in the ear. No safety data for oral mullein were located.
