Masterwort (Peucadanum – or Imperatoria – ostruthium)
Flowering: June to August. Height: 60cm (24in).
Also known as Felon-grass and Felonwort, very little is actually known about the plant’s history but archaeological findings show that it might have been introduced into the British Isles from Central Europe. The oldest evidence as a cultivated plant was from the early Middle Ages when it was known to be held in high regard. Masterwort alludes to its reputation as a plant with superior healing properties and its medieval Latin name ‘imperatoris’ means ‘master’ or ‘ruler’. ‘Master’ was once a title for a physician. Although Masterwort had a reputation as a medicinal plant for humans, it was also planted by the peasantry in England, mainly for veterinary use with cattle and for diseases of swine and horses. It is mentioned as an ingredient in remedies for sheep diseases in the 17th century. Nowadays it is an uncommon plant.
Medicinal: It is mentioned in several medieval and Renaissance herbals for various ailments. It was used in treating rheumatic conditions, shortness of breath, kidney and bladder stones and water retention while the leaves were wrapped around slow-healing wounds. It was especially valued for its ability to resolve all flatulence in the body and stimulate the flow of urine and menstruation. An infusion was said to reduce migraines and act as a sedative and its bitter juice was prized by country people for toothache. Powdered roots were added to wine as a protection against malaria. The English herbalist John Gerard wrote in The Herball (1597) that “the rootes and leaves stumped, doth dissolve and cure all pestilential carbuncles and botches, and such other apostemetions and swellings”.
Culinary: The entire plant smells strongly like celery and it has been (and still is) used as a condiment in food in various parts of Europe. Leaves were used as a potherb while the rhizomes were used to flavour cheeses and various liqueurs.
