Pine resin is a sticky substance produced by pine trees, primarily for protection against insects and diseases. It is a natural secretion that helps seal wounds in the tree's bark, preventing further damage. The resin is often harvested for various uses, including making turpentine and rosin. In addition to its industrial applications, pine resin has been used for centuries in traditional medicine and as a natural adhesive. It can also be found in products like candles and soaps, where it adds fragrance and enhances durability. Its unique properties make it valuable in both natural and commercial contexts.
