Peucedanum palustre (milk-parsley[1]) is an almost glabrous biennial plant in the family Apiaceae.

It is so called in English because of the thin, foetid, milky latex found in its young parts and is native to most of Europe, extending eastwards to Central Asia.

The two plants are not only similar in appearance, but also grow in similar habitats, although they may be told apart in the following manner: P. palustre has hollow, often purplish stems, pinnatifid leaf lobes and deflexed bracteoles; while S. carvifolia has solid, greenish stems, entire or sometimes lobed leaf-lobes and erecto-patent bracteoles.

[2] The roots of Peucedanum palustre have been used as a substitute for ginger in Southeastern Europe and likewise in Russia.

The English botanist John Lindley (under the heading Peucedanum montanum) also mentions the use of the root as an antiepileptic in the region of Courland in western Latvia (with its low-lying character, marshy coastline and numerous lakes, an area conducive to the growth of the plant).
