Mullein

Mullein (Verbascum thapsus) has invaded the landscape in the higher elevations of Hawai‘i and Maui. It is drought resistant, and can grow quickly to be 10 feet (3 m) tall in a short 2 years. It produces many seeds that can remain viable for up to 100 years.

The mullein isn’t an invasive threat where other plants easily grow. The European mullein is cultivated in its native habitat for medicinal purposes. It is used as an herbal treatment for lung infections and skin conditions.

The mullein tends to become a problem where the environment is harsh and vegetation is sparse. The alpine habitats of Hawai‘i and Maui provide an ideal opportunity for the mullein to fill gaps once occupied by slow growing native species.

Plants like the once common ‘ahinahina have been devastated by grazing animals. Animals prefer to eat the native plants that have lost their natural defenses. Grazing animals dislike mullein because the leaves are covered in irritating hairs.

In order to eradicate invasive species, the native plants need to be repopulated in addition to removing invasive. Grazing animals also need to be removed to allow native plants to reestablish.

Hi! I like your blog, it’s always a fresh air! May I ask you how do you use mullein? Maybe you have some tips for making tea or tincture? Because I take mullein every winter season to fight with my cough and for lungs detox, but I only take it in a form of mullein leaf extract, https://www.amazon.com/USDA-Organic-Mullein-Drops-Lungs/dp/B0CKBPTPRL some drops with licorice. It works great, but I would like to have some alternatives. Thank you!

  Mullein is generally considered safe for relieving cough, reducing mucous, and general inflammation reduction. The leaves, flowers, and roots can all be used. Individuals react differently and plants may have different strengths, so be cautious when trying new applications. For lung ailments, it can be used in an infusion for drinking to clear mucous. Large doses can cause side effects for some people, so start with a small amount in hot water. Mullein can also be added to hot water and inhaled as a steam.
  
  Mullein can also be used externally. Beware that hairs on fresh leaves can also cause allergic skin reactions in some people. Mullein can be used as a poultice for bruises, and as a mild topical disinfectant for small cuts and abrasions. In ancient times it was burned as incense to fumigate spaces and purge them of evil spirits.
  
  Mullein is invasive in Hawaiʻi and North America. It’s best to collect invasive mullein in the spring and early summer. It’s easier to remove the long taproot while the ground is still soft and moist. It’s also best to harvest before the plants develop seeds, to prevent spreading them.
