Pine trees are one of our best-loved trees. The sloping branches have been immortalized in art and been part of our holiday traditions. But these are not just of aesthetic value.

What is Pine?
Pine is actually a broad term that encompasses around 120 different species of coniferous trees that fall within the Pinaceae family. You can find its species in most of the Northern hemisphere, but there is only one that is native to the southern hemisphere. While some species have been introduced to tropical climates for lumber or ornamental purposes, pines are very hardy and tend to become invasive in these regions. Hence, they are usually discouraged. These trees can have long lifespans, some stretching to 1,000 years of age. The oldest known pine tree in the world is in California. It is over 4,500 years old. 
In terms of medicinal benefits, pine needles, cones, bark, and resin all hold medicinal qualities. Its essential oil is also highly valued. The innermost bark can be dried and eaten. It is valued for its high nutrient content, while the needles can be brewed into a popular tea that has a number of beneficial qualities. You can read about the individual products in our articles:
