Pine resin has multiple uses for survival. This sap is produced by the pine tree to seal up cuts or damages to the tree.
If you ever find yourself lost in a wilderness environment, having a pine tree in the area is one of the best case scenarios you can hope for. There are many different species of pine trees but they generally prefer open and sunny areas.
They are found abundantly throughout North America, they are also found throughout Central America, Europe, North Africa, in the Caribbean region, and in some places in Asia.
Native Americans used pine sap for medicinal purposes. The resin is either chewed on or made into a beverage by mixing with water. It is known to be very effective in treating stomach ulcers and rheumatoid arthritis. Modern medical experts have not verified the medicinal benefits of pine resin though.
Look for the damaged part of the pine tree because that will be where the resin secretions are. The resin will be dry and hardened but can be softened with heat. Look for damaged or fallen limbs first before you purposely cut into the pine tree’s bark for the sap. If you have to damage the tree, do it in a small area on one side only. Also, take only as much resin as you will need and leave some on the tree to protect the cut from boring insects.
