The mullein plant has been around for thousands of years. The plant is found in many parts of the world, including the United States, and has more than 200 species.
The most popular type commercially used is common mullein (Verbascum thapsus). The leaves are harvested near the bottom of the plant and used either fresh or dried to make various products.
Mullein oil is extracted from the flower or leaves of the plant. The oil is used as a remedy for earaches, eczema, and some other skin conditions.
One older studyTrusted Source showed some benefit for ear pain based on a trial of 171 children between 5 and 18 years old with an ear infection. They were given antibiotics or herbal drops with or without a topical anesthetic.
Researchers found the herbal drops reduced pain. They also pointed out that they cost less than antibiotics and didn’t have any side effects.
Mullein oil can be made from either fresh or dry parts of the plant by either hot (active) or cold (passive) processing:
- Hot oil infusion. This process involves using a double boiler technique to gently heat a carrier oil, such as olive oil, with mullein leaves or flowers for up to 3 hours. Then the product is strained and stored.
- Cold-steeped oil. The cold process usually involves steeping dry flowers or leaves in carrier oil for 7 to 10 days.
Mullein oil is also available online and at health food stores ready-made.
