Pine family (Pinaceae)

Information about the plant

The Spruce dominates the woodlands of North and Central Europe. When young it grows very slowly, after 20 years it starts to grow strongly upwards, driving the tree 30 to 40m in height. The great regularity of the tree´s taper makes it a popular ornamental tree. The needles of the Spruce are 1.3 to 2.5cm long, pointed and angular and grow spirally around the twig. The Spruce blossoms every three to four years and forms the hanging cones, 10 to 15cm long, whose winged seeds fall in the following spring. In autumn, the empty cones can be found under the tree.

Medicinally used parts of plants (herbal drug)

The fresh spruce tips and essential oil (pine oil) extracted from the fresh, chopped branches and needles through steam distillation are used.

Constituents of the herbal drug

Fresh spruce tips contain essential oils and flavonoids, pine needle oil consists of monoterpenes, mainly bornyl acetate, pinene, phellandrene and camphene.

Quality of the drug

There is no official quality specification for fresh spruce tips (Picea turiones recentes) and the quality of the pine needle oil (Piceae aetheroleum) is specified in the German Pharmacopoeia (DAB). It also states there that oil from the Siberian fir (Abies sibirica Ledeb.) can be obtained, its needles contain a similarly formulated essential oil.

Medical applications

Recognised medical use

The Commission E has assessed both fresh pine tops and pine needle oil and describes identical areas of use for them: internally for colds of the respiratory tracts; externally to treat rheumatic complaints (heat therapy) and for nerve pain.
