The leaves may contain rotenone, which is used as an insecticide.

Medicinal Uses:
Great mullein is a commonly used domestic herbal remedy, valued for its efficacy in the treatment of pectoral complaints. It acts by reducing the formation of mucus and stimulating the coughing up of phlegm, and is a specific treatment for tracheitis and bronchitis.
The leaves and the flowers are maildly pain-relieving, anti-inflammatory, antiseptic, antispasmodic, and have agents that cause tissue to contract, induce urination, that soften and soothe the skin when applied locally, that induce the removal (coughing up) of mucous secretions from the lungs and are used for healing wounds, fresh cuts, etc., usually used as a poultice. A tea is taken internally in the treatment of a wide range of chest complaints and also to treat diarrhea. The plant combines well with other expectorants such as coltsfoot (Tussilago farfara) and thyme (Thymus vulgaris). Externally, a poultice of the leaves is a good healer of wounds and is also applied to ulcers, tumours and piles. Any preparation made from the leaves needs to be carefully strained in order to remove the small hairs which can be an irritant. The plant is harvested when in flower and is dried for later use. An infusion of the flowers in olive oil is used as earache drops, or as a local application in the treatment of piles and other mucous membrane inflammations. This infusion is also strongly bactericidal.
A decoction of the roots is said to alleviate toothache and also relieve cramps and convulsions. The juice of the plant and powder made from the dried roots is said to quickly remove rough warts when rubbed on them. It is not thought to be so useful for smooth warts. The seeds are slightly narcotic and also contain saponins. A poultice made from the seeds and leaves is used to draw out splinters. A decoction of the seeds is used to soothe chilblains and chapped skin. A homeopathic remedy is made from the fresh leaves. It is used in the treatment of long-standing headaches accompanied with oppression of the ear.

Other Uses:
A yellow dye is obtained from the flowers by boiling them in water. When used with dilute sulphuric acid they produce a rather permanent green dye, this becomes brown with the addition of alkalis. An infusion of the flowers is sometimes used to dye the hair a golden color. The flowering stems can be dipped in wax and used as torches. The down on the leaves and stems makes an excellent tinder when quite dry. It is also used as an insulation in shoes to keep the feet warm and to make wicks for candles.
