The so-called oil of juniper wood is now a days used only in veterinary practice and as an external remedy in domestic medication. It is mostly a turpentine oil that has been distilled over juniper wood or twigs, some times it is a juniper berry oil diluted with turpentine oil. Hence the properties of commercial "juniper wood oil" vary with these practices.

3) Of the earlier investigations of juniper oil the following should here be mentioned: Blanchet, Liebig's Annalen 7 (1833), 167; Dumas, Liebig's Annalen 15 (1835), 159; Soubeiran and Capitaine, Liebig's Annalen 34 (1840), 324.
4) Blanchet, loc. cit; the crystalline deposit observed by Zaubzer [Repert. f. d. Pharm. 22 (1825), 415] differed according to Buchner (ibidem 425) from turpentine camphor or terpin hydrate.
