What does NCR mean in DRUGS

NCR, or Natural Coniferous Resin, refers to the viscous, sticky substance secreted by certain coniferous trees, such as pines, firs, and spruces. It is a complex mixture of organic compounds, primarily composed of terpenes, resin acids, and fatty acids. Coniferous resins play a crucial role in protecting the trees from environmental stressors and pests.

NCR is typically a viscous liquid that hardens upon exposure to air. It has a strong, characteristic odor and varies in color from light amber to dark brown. NCR is insoluble in water but soluble in organic solvents like alcohol and turpentine. It exhibits adhesive and waterproofing properties, making it valuable for various industrial and traditional applications.

The primary components of NCR are terpenes, resin acids, and fatty acids. Terpenes are hydrocarbons that give NCR its characteristic aroma. Resin acids are organic acids responsible for the sticky and adhesive nature of NCR. Fatty acids contribute to the waterproofing properties of NCR.

For centuries, NCR has been used in traditional medicine, primarily for its antiseptic, anti-inflammatory, and expectorant properties. It has been applied topically to treat wounds, burns, and skin irritations. Additionally, NCR has been employed as an ingredient in incense, varnishes, and waterproofing agents.

NCR finds widespread use in various industries, including the paper industry for sizing and coating, the paint industry as a binder and thickener, and the adhesive industry for its bonding properties. It is also used in printing inks, sealants, and other specialized products.

NCR is typically collected through tapping, a process where incisions are made on the bark of the trees to stimulate the flow of resin. The resin is then allowed to drip into containers or channels. Other methods include solvent extraction and distillation.
