Great Mullein - Verbascum thapsus
Herb: Great Mullein
Latin name: Verbascum thapsus
Family: Scrophulariaceae (Figwort Family)
Medicinal use of Great Mullein: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 anodyne, anti-inflammatory, antiseptic, antispasmodic, astringent, demulcent, diuretic, emollient, expectorant and vulnerary. An infusion is taken internally in the treatment of a wide range of chest complaints and also to treat diarrhoea. 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.
Description of the plant:
Habitat of the herb:Sunny positions in uncultivated fields and waste ground, especially on dry soils.
Edible parts of Great Mullein:An aromatic, slightly bitter tea can be made by infusing the dried leaves in boiling water for 5 - 10 minutes. A sweeter tea can be made by infusing the fresh or dried flowers.
Other uses of the herb: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 colour. 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 candle. One report says that the leaves contain rotenone, though it does not say in what quantity. Rotenone is used as an insecticide.
