More About Genuine Pine Tar

Pine tar is a vegetable liquid obtained from the wood of various trees of the family Pinaceac by distillation. Using a process that is centuries old, pine stumps and roots are burned very slowly in special kilns. This pine tar is a resin rich liquid that is extracted from the bottom of the kiln. This is authentic Stockholm tar. Genuine Pine Tar has been valued for hundreds of years as a preservative for wood and natural fiber rope. It is the smell of the square-rigged ship. Traditional sailors describe this rare grade of tar in words usually reserved for fine wines and tobaccos.

The product is still used to a great extent for wooden constructions such as shingles, bridges, boats, barges and cottages. The Swedish Cultural Management recommends pine tar as surface treatment of wooden church roofs and other cultural buildings made of wood. There are examples of stave churches that have been preserved with pine tar for nearly a thousand years with very few intervals of maintenance. It is also used for veterinary purposes, in hoof moisture retention of horses, cattle and sheep and for pharmaceutical purposes as treatment of different kinds of skin diseases. Pine tar can be found as an ingredient in shampoos, soaps, and expectorants and in ointments against allergic rash, psoriasis and eczema, among others. Another different field of application of pine tar is as a softener when manufacturing rubber tires.
