Pine family — pinaceae
It is a large coniferous evergreen trees with a pyramidal-conical crown up to 30 m tall.
The needles are fragrant, flat, soft, non-prickly.

Spreading and habitat. Fir is a forest-forming species of some types of taiga. Siberian fir is common in the northeast of the European part of the country, in the Urals, in Western and Eastern Siberia, where it reaches the headwaters of the Aldan River, in Kazakhstan. White fir - inhabitant of the forests of the Far East.
The chemical composition of Siberian fir cones
The ends of the branches («fir foot») Siberian fir contain
- up to 3% of essential oil, consisting of half of bornyl acetate (30-60%),
- as well as borneol, camphene, alpha and beta pinene, etc.
The fresh needles contain:
- up to 0.32% ascorbic acid,
- non-magnesium, chlorophyll derivative - pheophytin, carotenoids, vitamin E, sterols and phytoncides.
The yield of essential oil from the protected shoots of white fir fir is 2.5%.
Among monoterpenes in it prevail
- alpha pinene (28%),
- beta pinene and myrcene; vinyl acetate (25%) and chamazulene predominate in the high-boiling fraction.
Delta3-Karen is contained in fir needles oil can cause allergies and dermatitis, therefore it is necessary to strictly follow the distillation technology, which allows you to adjust the amount of this substance. In the bark of the young trees, the sap is accumulated, which is a yellow, very transparent liquid with a density of 0.969-0.998.
Resin consists of:
- 30% of essential oil and
- 70% of resin.
Resin contains up to 50% resin acids (mainly levopimaric acid) and 18-25% of hydrocarbons - resenes.
According to its properties, the sap of fir differs from the sap of other conifers: it thickens in the air and turns into a glassy mass - rosin.
Harvesting and storage of raw materials
The harvesting of needles and young branches is carried out when harvesting wood.
The ends of branches 30-40 cm long, are chopped off or trimmed usually in winter. It is laid on the flooring of the poles, shifting layers of spruce branches with snow.
Possible harvesting could be in the summer, in July - August.

From the needles of Siberian fir get water extract «Abisib», which has a pronounced
- regenerating properties
- stimulating the blood system,
- stimulating the immune system.
Resin is used in microscopic practice for the manufacture of permanent micro-specimens, in the optical industry for bonding lenses.
From fir needle oil: receives semi-synthetic (levorotatory) and camphor.
- tones the respiratory and vasomotor centers,
- positive effect on lung ventilation,
- improves myocardial function and pulmonary blood flow.
It is used as an injection under the skin:
- in the treatment of acute and chronic heart failure,
- respiratory depression
- with pneumonia,
- in case of poisoning with hypnotic preparations and narcotic preparations.
Camphor is used externally as
- antiseptics alone and as part of complex preparations.
It is contradicted with the inclination to convulsions;
- kidney diseases in the acute stage (glomerulonephritis, pyelonephritis).
