It is native to the temperate regions of the northern hemisphere. The major producers include Italy, Hungary, France, Austria, Czech Republic, Slovakia, Germany, Poland, Russia and Spain. The berries collected in northern Italy, Hungary, France, Austria and the Czech Republic are considered superior in quality than those collected in other regions. The part used is the dried, mature female cone, which is generally called “berry” because of its berrylike appearance. A colourless to pale green essential oil is obtained through steam distillation of the crushed, dried, partially dried, or fermented berries.
