Peucedanum ostruthium or Imperatoria ostruthium, masterwort, is a species of flowering plant in the family Apiaceae. It is native to the mountains of Central and Southern Europe, but has been widely introduced outside its native range.

Description

A herb. It keeps growing from year to year. It grows 25-70 cm tall. The leaves are twice divided with 3 large leaflets. The flowers are white or pink and in large flat topped groups.

Edible Uses

The leaves are edible cooked, used as a potherb or as a flavouring. The aromatic roots are also used as a flavouring and are said to taste hotter than pepper. A popular fermented drink is made from the roots.

Traditional Uses

The leaves are boiled and eaten as a potherb. The roots have been used in the preparation of gin and in cheese. They are also used for tea. The bitter element must be removed before using the starch.

Medicinal Uses

Masterwort is rarely used in modern herbalism but may merit further investigation. It was highly regarded during the Middle Ages, particularly for its ability to dispel flatulence and stimulate urine and menstrual flow. It was also used for rheumatic conditions, shortness of breath, kidney and bladder stones, water retention and wounds. The root is antispasmodic, aromatic, bitter, strongly carminative, diaphoretic, digestive, diuretic, emmenagogue, expectorant, febrifuge, stimulant and stomachic, and is useful in treating asthma, dyspepsia and menstrual complaints. An infusion can help relieve migraine. The root is harvested in spring or autumn and dried for later use. An essential oil from the plant has euphoric and odontalgic effects and relieves skin irritation when applied externally. External use of the plant or its essential oil can cause an allergic reaction to sunlight. A homeopathic remedy is also prepared from the roots.
