The pine is one of the most useful trees on the planet, providing food, shelter, medicine and fuel. Knowing how to utilize this versatile resource could someday be the key to your very survival if you find yourself alone in the wilderness.
There are many species in the pine family (or genus Pinus), and they can be found virtually everywhere in the world.
Here are just a few of the many uses for pine trees (or conifers):
Many types of pine needles can be used to make a tea rich in vitamin C. Simply steep a handful of needles for 5-10 minutes. The longer you steep them, the less vitamins will remain, so don't overdo it.
It's important to note that some pine needles are poisonous — be sure to avoid consuming the needles from the Norfolk Island Pine (Araucaria heterophylla), the Yew (Taxus) and the Ponderosa Pine (Pinus ponderosa — also known as Western Yellow Pine, Bull Pine and Blackjack Pine). Make sure to learn the differences between the edible and non-edible varieties before making pine needle tea.
Pine nuts from all varieties of pine are edible, although some are small and not typically harvested. They can be a little tricky to harvest and perish quickly once they are shelled but can be stored longer if left in their shells or roasted.
Inner pine bark and pine resin are edible; male pine cones and their pollen can also be eaten. Native Americans chewed pine resin as sort of a natural chewing gum. The inner bark of large pine trees is edible, and the bark from young pine twigs can be eaten as well. Be careful not to damage or kill a pine tree by tearing off too much bark, and never “ring” the bark from a pine tree.
