Joseph Liboschitz, or Osip Jakovlevič Libošic; Осип Яковлевич Либошиц (1783–1824) was a Russian physician and naturalist from Vilnius.
Subsequently, he practiced medicine in his hometown of Vilnius, later relocating to St. Petersburg, where he served as a court physician (from 1812) and personal physician to Tsar Alexander I (from 1822).
In St. Petersburg, he founded a children's hospital.
[1] With Carl Bernhard von Trinius he edited the exsiccata Description des Mousses qui croissent aux environs de St. Pétersbourg et de Moscou (1811).
[2] Liboschitz was the first to provide a description of Rehmannia chinensis (synonymous with Rehmannia glutinosa),[3] an important herb in traditional Chinese medicine.
