This is the resin of conifers. It is a fragrant, sticky substance, a waste product of coniferous trees (pine, fir, spruce, larch), which is released when the bark is damaged.
Outwardly, sap is a viscous liquid of a viscous yellowish consistency. Has a pronounced resinous coniferous aroma. It can also be in solid form, as it crystallizes under the influence of oxygen and hardens quickly.
The resin of any coniferous tree includes:
- volatile substances (32 - 35% ) - monoterpenes (a - and b - pinene, b - pellandrene, camphene, karen, liminene, etc. );
- diterpenes, sexviterpenes and their derivatives (8 - 10% );
- resin acids (77 - 77.5% ) - abietic, lambertianic, dextropimaric, dehydroabistic, levopimaric, pimaric, palustric, sapicic, etc. ;
- fatty acids (0.3% ) - lauric, palmitic, palmitoleic, oleic, stearic, etc. ;
- resin alcohols - rubbers and resinotannols;
- resin alcohols - rubbers;
- macro - and microelements;
- succinic acid.
The resin of different coniferous trees differ from one another in the content and composition of neutral substances. "Neutral substances" are on average from 6 to 20% of the total mass of the resin and determine the specificity of the therapeutic and prophylactic action of one or another type of resin:
- in the resin of Scots pine - 3 - 4% (pimaradien, pimarinol, abietinol, abietinal, methyl dehydroabietate, etc. ).
It is used in medicine and cosmetology.
Storage conditions and shelf life
The unique property of natural resin is that it does not age and retains its medicinal properties for centuries. Its only feature is that, under the influence of air, it gradually crystallizes and becomes solid. This makes its use rather difficult, but the problem is easily solved by heating.
It is advisable to store medicinal products prepared on its basis in a dark, dry, cool place for no more than 3 months.
