Resin circulates throughout a coniferous tree and a few others, and serves to seal damage to the tree. Harvesting pine resin dates back to Gallo-Roman times in Gascony . Tapping pines may either be done so as to sustain the life of the tree, or exhaustively in the years before the tree is cut down.
Pine resin (sap) has been used by various tribes to waterproof baskets, pails, and boats. The Ojibwe also used pine resin to successfully treat infections and even gangrenous wounds, [40] because pine resin apparently has a number of quite efficient antimicrobials. Generally, a wet pulp from the inner bark, or pine tar mixed with beeswax or ...
Rosin (/ ˈ r ɒ z ɪ n /), also known as colophony or Greek pitch (Latin: pix graeca), is a resinous material obtained from pine trees and other plants, mostly conifers. The primary components of rosin are diterpenoids, i.e., C 20 carboxylic acids. Rosin consists mainly of resin acids, especially abietic acid. [1]
Pitch produced from petroleum may be called bitumen or asphalt, while plant-derived pitch, a resin, is known as rosin in its solid form. Tar is sometimes used interchangeably with pitch, but generally refers to a more liquid substance derived from coal production, including coal tar , or from plants, as in pine tar .
The refined resin is sometimes available as a translucent solid and is then "run" by cooking or melting it in a pot over heat without solvents. The thickened oil and prepared resin are then cooked together and thinned with turpentine (away from open flame) into a brushable solution. The ingredients and processes of violin varnish are very ...
The word resin comes from French resine, from Latin resina "resin", which either derives from or is a cognate of the Greek ῥητίνη rhētínē "resin of the pine", of unknown earlier origin, though probably non-Indo-European. [10] [11]

Resin canal characteristics (such as number, size and density) in pine species can determine its resistance to pests. In one study, biologists were able to categorize 84% of lodgepole pine, and 92% of limber pines, as being either susceptible or resistant to bark beetles based only on their resin canals and growth rate over 20 years.
