Especially the rhizomes of P.ostruthium (Radix magistralis) are traditionally used as ingredient of liqueurs and bitters. The dried herb and the roots were used as folk medicine and regarded as diaphoretic, diuretic, stomachic, sedative; now mainly used as spice and stomachic.
[Hagers Handbuch der Pharmazeutischen Praxis, Springer 2010]

„Masterwort is used as a flavouring for various liqueurs and bitters. Its roots and leaves have been used in the traditional Austrian medicine internally (as tea, liqueurs and wine) and externally (as fumigation, tincture or incense) for treatment of disorders of the gastrointestinal tract, skin, respiratory tract, cardiovascular system, infections, fever, flu and colds.“

„On carrageenan-induced rat paw edema, oral administration of 10% ethanolic extracts led to a marked inhibition of the edema. By means of bioassay-oriented fractionation of extract, 6-(3-carboxybut-2-enyl)-7-hydroxycoumarin proved to be the most important anti-inflammatory principle of the plant. 30 micrograms/kg of this compound inhibited the formation of edema to an extent of 50%.“

„Essential oil from herb and rhizome of Peucedanum ostruthium (L.Koch.) ex DC un­derwent qualitative and quantitative analyses. The content of the oil obtained by hydrodistil­lation was 0.95% in the herb and 1.25% in the rhizome (per dry weight basis).
Gas chroma­ tography (GC) with MS detection and flame ionisation detection showed that the oil from the rhizome contains 39 compounds, of which 29 were identified. Gas chromatography with flame ionisation detection in chiral columns against standard compounds showed the presence of enantiomers of some of the components of the oil. Compounds present in largest quantities are: sabinene (35.2%) of which (+)sabinene accounts for (96.54%) and 4-terpineol (26.6%) of which (+)4-terpineol accounts for (65.8%).
44 components were found in the herb essential oil, of which 39 compounds were identified. Compounds present in largest quantities were β-caryophyllene (16.1%) and α-humulene (15.8%). The content of sabinene in the herb oil was 4.7%. The following compounds were present in the herb oil only as enantiomers: (+)sabinene (4.7%), (-)limonene (4.4%), (-)β-pinene (0.4%).
A coumarin (osthole) was detected in both essential oils (5.5% in herb oil and 5.1% in rhizome oil).“

HPLC profiling of the CH2Cl2 extract led to the identification of seven coumarins as major constituents. „The total coumarin content in this CH2Cl2 extract was determined to be 78%, whereas the content per gram dry weight of plant material was 6%. Ostruthin was quantified as the main coumarin (41% of the total coumarin content), followed by oxypeucedanin (18%), ostruthol (13%), imperatorin (12%), isoimperatorin (9%), oxypeucedanin hydrate (6%), and osthole (1%).“

Main coumarins of dichloromethane extracts of commercial P.ostruthium root samples were the linear furanocoumarins oxypeucedanin hydrate (2-7%), oxypeucedanin (17-20%), ostruthol (12-14%), imperatorin (12-15%), isoimperatorin (9-10%), and oxypeucedanin ethanolate and the simple coumarins osthole (1%) and ostruthin (38-41%). A chromone, peucenin, was identified by LC-MS only.
