Mullein Leaf
Latin Name: Verbascum thapsus
Herb Class/Action:
Mullein leaf is classified as an expectorant, demulcent, anti-inflammatory, respiratory tonic, and astringent.
Parts of Plant Used:
The leaves are most commonly used medicinally, typically dried for teas, steams, or tinctures. The flowers and roots are also used, but this monograph focuses on the leaf.
Flavors:
Mullein leaf has a mild, slightly bitter, earthy flavor with a soft, smooth texture when infused.
Energetics:
Mullein is energetically cooling and moistening to dry tissues.
Medicinal Properties:
Respiratory Support: Mullein is a classic lung herb. It soothes inflammation in the respiratory tract, loosens mucus, and helps the body expel it. It’s used for dry, irritated, or unproductive coughs, bronchitis, asthma, and general lung weakness.
Demulcent and Soothing: Its mucilage content helps coat and protect mucous membranes, making it useful for dry throats, hoarseness, and scratchy coughs.
Anti-inflammatory and Astringent: Mullein reduces inflammation and gently tones tissues. It’s supportive for inflamed lungs, sore throats, and urinary tract irritation.
Ear and Lymphatic Support: While the flowers are more commonly used in ear oil, the leaf can also support lymphatic drainage in the neck and chest region.
Smokable and Lung Tonic: Mullein is traditionally included in herbal smoking blends to support lung health and reduce irritation from tobacco or environmental exposures.
In the Garden:
Mullein is a biennial plant native to Europe and naturalized across North America. It thrives in full sun and poor, rocky, or disturbed soil. In its first year, it forms a low rosette of large, fuzzy, silvery-green leaves. In the second year, it sends up a tall flowering stalk (5–8 feet high) with small yellow flowers. Leaves are best harvested in the first year or early in the second before flowering. Dry thoroughly, as they are prone to mold due to their thickness.
Culinary Uses:
Mullein is not typically used in culinary preparations. It is primarily consumed as an herbal tea or used in steam inhalations. When making tea, always strain through a fine mesh or cloth to remove tiny leaf hairs that can be irritating to the throat.
Precautions:
Mullein is generally very safe and well-tolerated by all ages. Ensure leaves are well-strained before internal use to avoid throat irritation from the fine hairs. Use caution when wildcrafting, as it can grow near roadsides or contaminated soils. Store dried leaves in a dry, airtight container to prevent mold.
