Mullein leaf (from Verbascum thapsus), is a member of the snapdragon family. It has anti-inflammatory properties and is also an expectorant (a substance that assists in the thinning of mucus or phlegm). Mullein leaf can benefit your respiratory system, especially when fighting illness, in several ways.

Mullein calms inflammation, so that when you have lung and throat issues, using mullein may relieve some of your discomfort. Its leaves contain mucilage, which coats mucous membranes (the moist linings inside of your respiratory tract) with a film thereby reducing inflammation. Its expectorant properties make it easier to break up mucus to get it out of your respiratory system.
