Mullein (Verbascum thapsus) is one of those home remedies that you can add to your arsenal of cold, flu and other respiratory ailments. The fuzzy, silvery leaves of the weed are soothing and anti-inflammatory and it's been used for centuries to soothe irritated lungs and clear out excess mucus. It's a good addition to herbal smoking mixtures and can be smoked by itself or mixed with milder herbs.
The question of can you vape mullein is a no-brainer. Like most herbal plants, it can be vaporized and is safe to do so because you're not inhaling the combustion byproducts like carbon monoxide that are produced when you smoke herbs with traditional smoking methods. Its neutral flavor and aroma allow it to be mixed with milder herbs to create herbal smoking blends that are relaxing, healing, and beneficial for your lungs and respiratory system.
This is especially true because it's a lung tonic and an expectorant, meaning that it loosens bronchial secretions and makes it easier to eliminate phlegm from the lungs. It's also gentle enough to use when you're getting rid of tobacco and it's excellent for a general lung cleanse, as well as to soothe the lungs during a flu or cold. However, it's best used in moderation, as prolonged use can build up a tolerance. It's not recommended for pregnant or breastfeeding women and people with liver and kidney issues, as it can interact negatively with those conditions.
