Mullein leaf, or Verbascum thapsus, is an herb with a long history of use in European and Mediterranean herbal traditions for respiratory comfort. Double Wood provides mullein as a concentrated 10:1 extract, offering a convenient alternative to traditional mullein tea or plain leaf powder.Mullein naturally contains saponins, mucilaginous compounds, flavonoids, phenylethanoids, and iridoids. Saponins are traditionally associated with supporting the body’s natural mucus-clearing processes, while mucilaginous compounds can help coat and soothe irritated tissues in the throat and respiratory tract.Double Wood Mullein Leaf Extract is commonly chosen by people looking to support comfortable breathing, normal airway function, and respiratory wellness, including individuals who have experienced smoking or increased exposure to dust, pollution, or other environmental irritants.Each two-capsule serving provides 1,000 mg of a concentrated 10:1 mullein leaf extract. A 10:1 ratio means that approximately 10 grams of raw mullein leaf are used to produce 1 gram of concentrated extract, giving each serving the equivalent of approximately 10,000 mg of dried mullein leaf.Soy-Free, Gluten-Free, Non-GMO, Vegan
