Senecio jacobaea

Family : ASTERACEAE
Common Name (UK) : Common Ragwort
Common Name (DE) : Jakobs-Greiskraut
Common Name (FR) : Séneçon Jacobée, Herbe de Jacob, Herbe Saint-Jacques
Habitat : Dry roadsides, waste ground and pastures
Remarks : "Ragwort was formerly much employed medicinally for various purposes. The leaves are used in the country for emollient poultices and yield a good green dye, not, however, permanent. The flowers boiled in water give a fair yellow dye to wool previously impregnated with alum. The whole plant is bitter and aromatic, of an acrid sharpness, but the juice is cooling and astringent, and of use as a wash in burns, inflammations of the eye, and also in sores and cancerous ulcers - hence one of its old names, Cankerwort. It is used with success in relieving rheumatism, sciatica and gout, a poultice of the green leaves being applied to painful joints and reducing the inflammation and swelling. It makes a good gargle for ulcerated throat and mouth, and is said to take away the pain caused by the sting of bees. A decoction of the root has been reputed good for inward bruises and wounds. In some parts of the country Ragwort is accredited with the power of preventing infection." from Botanical.com
