I know this just looks like a plate of globby yuck. But if you could smell this divine goo you would see it through a different lens. This is freshly harvested Pine pitch, from my Aunties huge old pines in her back yard. The two trees were virtually gushing and I couldn't resist. This plate is only about 1/4 of what we got. We were sure to leave a coating on from each spot through, not to leave the tree raw.
The white powdery looking coat is where the sap had begun to dry out, the area where it was exposed to air. Th more mature the sap gets, the harder it gets. Some Red Pine sap that my son recently found was nearly hard, and not nearly as sticky. I'm guessing it was at least five years old. It takes a long time.
Usually what I like to do with the pitch is make smudge. I make little rolled balls and 'flour' it in Lavender or Rose powder. This helps keep it self-contained and keeps your fingers from gluing together. Plus it smells really sweet. When you have finished rolling them, lay them out on a wax-paper covered tray, indefinitely. If you jar them up you will have a jar full of melted sap and good luck getting it out. The little balls are easy to pick up and add to a hot rock or glowing ember to bless your home or ceremony. However, I don't recommend using it in your fireplace or wood stove. To easily remove the sap from fingers or floors or clothes, apply rubbing alcohol.
Another superb use for this wonderful gift of the trees is for splinters or slivers. Our beloved Kiva has dealt with this recently only with glass. Sucks it right out and keeps the infection at bay. A wound or cut in the woods is treated swiftly with an application of fresh pitch. Blisters can be helped when nothing else is around and you're mid-hike. Gum infections are also traditionally helped with sap - although I have to say it's not palatable. Natives also used it as glue and water sealer for their canoes.
