Benefits and Uses of Mullein Leaf

Here are some of the main potential benefits and uses of mullein leaf based on its traditional uses and active plant compounds:

Respiratory Support

One of the most common traditional uses of mullein leaf is for respiratory support. The herb's mucilage content helps to coat and soothe mucus membranes in the throat and lungs. Mullein leaf also contains saponins that are natural cleansing agents and can help promote respiratory health. Studies suggest the antioxidants and anti-inflammatory compounds in mullein leaf can also be beneficial for chronic inflammatory airway diseases like asthma.

Soothe Sore Throats

The demulcent properties of mullein leaf make it an excellent choice for soothing sore throats. Mullein leaf has mild anesthetic properties that can provide temporary numbness and pain relief. Make a cup of mullein tea or use mullein leaf tincture and gargle to help relieve throat pain and irritation.

Ear Pain and Congestion

Mullein leaf oil is commonly used to naturally treat ear pain and ear congestion associated with middle ear infections. The oil may help reduce inflammation and fight bacterial/viral infections in the ears when applied directly inside the ears. Always consult a doctor before using mullein leaf oil in ears.

Anti-inflammatory Effects

Research indicates the triterpenoid saponins and flavonoids in mullein leaf have potent anti-inflammatory activities. Using mullein leaf extract may help reduce inflammation associated with various health conditions. More studies are needed to rate its effectiveness for specific inflammatory disorders.

Skin Soothing

Mullein leaf has traditionally been used to make skin-soothing creams, poultices, and oils due to its anti-inflammatory and antimicrobial properties. Applying mullein leaf topically may help reduce redness, swelling, and irritation associated with minor wounds, burns, hemorrhoids, and eczema.
