The roots are used in the important traditional Chinese medicine “qian hu” (see also Peucedanum praeruptorum), particularly in the treatment of colds, coughs, and fevers. White-flowered plants in NE China may be referred to Angelica decursiva f. albiflora (Maximowicz) Nakai (J. Coll. Sci. Imp. Univ. Tokyo 16(1): 268. 1909; Peucedanum decursivum var. albiflorum Maximowicz, Melanges Biol. Bull. Phys.-Math. Acad. Imp. Sci. Saint-Pétersbourg 12: 473. 1886).

Evolution
(
англиски
)
добавил Plants of Tibet
Phylogenetic affinities and historical biogeography of Angelica and its allies (Apiaceae tribe Selineae) were inferred from nuclear ribosomal DNA internal transcribed spacer sequences (Feng et al., 2009). Results corroborate a monophyletic Angelica (Angelica sensu stricto) upon the inclusion of Coelopleurum, Czernaevia. Angelica decursiva, which phylogenetic affinities is confirmed within Angelica. Northeast Asia (including Japan, northeast China, Korea and adjacent areas of Russia), Western Europe, and North America are inferred to be ancestral areas of Angelica based on optimal solutions of a dispersal-vicariance analysis, with the Hengduan Mountains likely providing a refugium for Angelica during the latter part of the Tertiary.
