Found in Ireland, Wales and England but not in Scotland. It is found on roadsides, wasteland and as a weed of arable land. A native of Europe and North Africa, it is now well-established throughout the world.
The Greeks believed it was an antidote to all poisons. In folk medicine, it was used to soothe sore throats - indeed one name for it is singer's plant. This plant "grows by our roadsides and on waste ground, where it is a common weed, with a peculiar aptitude for collecting and retaining dust...it is named by the French the 'Singer's Plant,' it having been considered up to the time of Louis XIV an infallible remedy for loss of voice. Jean Racine, writing to Nicolas Boileau, recommends him to try the syrup...in order to be cured of voicelessness." It is "good for all diseases of the chest and lungs, hoarseness of voice...the juice...made into a syrup with honey or sugar, is no less effectual...for all other coughs, wheezing and shortness of breath...the seed is held to be a special remedy against poison and venom." It was "formerly used for hoarseness, weak lungs and to help the voice." Herbalists use the juice and flowers for bronchitis and stomach ailments, among other uses, and as a revitalizer. In Tibetan medicine it is used to repress the symptoms of food poisoning.
