In today’s health-conscious world, herbal remedies are experiencing a well-deserved revival. Among the vast range of natural infusions, mullein tea stands out for its deep-rooted history and impressive array of health benefits. While it might not yet be a household name like green tea or chamomile, mullein has been used for centuries as a traditional remedy, particularly for respiratory health.
Whether you’re new to herbal infusions or a tea connoisseur looking to try something different, this post will guide you through everything you need to know about mullein tea—from its nutritional content and health benefits to how to make it and when to drink it.
What is Mullein?
Mullein (Verbascum thapsus) is a biennial plant native to Europe, Asia, and North Africa but has since naturalized across North America. It’s instantly recognizable by its tall stalk, yellow flowers, and fuzzy leaves. Known as a “weed with benefits,” this hardy herb has been used for centuries in herbal medicine.
The flowers, leaves, and roots of the mullein plant have been used to create tinctures, oils, poultices, and teas—each with its own unique application. But when it comes to mullein tea, it’s typically the dried leaves and flowers that are used.
Historically, it was employed by ancient Greeks and Romans to treat lung diseases, while Native American tribes used it as a remedy for asthma and tuberculosis. Fast forward to today, and mullein is gaining popularity as a natural alternative to pharmaceutical cough syrups and antibiotics.
