This is a very simple cure that has been around for a long time. The Native Americans used this. Pine sap has many uses, and pine trees (where I live) are very common. One of these uses is to help heal cuts. It's very simple and requires very little work. One thing I should mention though, is that I Accept no responsibility for anything, and if you have any questions consult a doctor!

Step 1: Find a Pine Tree

This is important, you need to find a tree (obviously) to collect sap. Also make sure it's on YOUR property or you have permission to CUT into the tree. This (when done correctly) won't kill the tree, but may leave scars on the branch/es used.
You also need to make sure it's the right type. It really doesn't matter too much, but you are free to experiment. Make sure that the tree you are using are FULL GROWN. The small trees may not make it through if you cut them! Also make sure the tree has needles not the weird leaves on those little "faux pine trees" that are used for lawn decor.

Step 2: Cut the Bark

Taking a sharp knife, cut carefully a small square out of the bark. If possible avoid cutting the tree, instead find a spot that already is dripping sap. The main reason is to insure that the sap is fresh. If the already dripping sap looks hardened, yet has 'give' to it, just take the knife and poke it gently, it will begin to ooze out the now free sap. If you do cut the mark then you might have to wait for it to drip down. You could also cut down the tree vertically and attach a bag to collect the sap like pictured. Also if you do decide to make a large incision (like pictured) it won't do too much damage as long as you cut ONLY the bark and to not cut through the marble like under surface!!

Step 3: Wait...

Wait for the sap to drip into the bag. It'll be a while. BUT don't go inside! Instead enjoy the outdoors! Go on a hike or just sit there and wait. I just watched wildlife planning to kill me...

Step 4: Take the Sap

I don't have a picture of this step, but just take your bag of sap and take it inside. Carefully remove any objects (twigs,leaves, etc) or dirt that has fallen in. You'll find it emits a strong odor, I really enjoy the smell of pine, but if you don't, simply close the bag. While doing this make some delicious Pine tea. Yum! Also be very careful for bugs, sap is like tar to them, they will go to eat it, then will get stuck and die or suffocate. You don't want to eat bugs, that's why it's good to get fresh sap!

Step 5: Boil (optional)

I didn't boil mine, but you could. This is more of an "on the trail" cure so you wouldn't really, but you could if you desired. It also might sanitize it more, but I'm not completely sure. Boiling the sap is usually only used when you end up eating it.

Step 6: Apply!

Ready to use! Simply take a small bit of the sap and apply to the cut. (NOTICE: This is your choice! Adding any foreign liquid into an open wound has risks! I did this many times and am fine, but it is not my fault if somehow something happens! This is mainly for emergencies that may occur during a hike in the middle of no where! But could be used other times!). How does it work? Pine sap hardens over time, and will develop a film over the wound, sort of like liquid band aid. Then ta-da your done!

Step 7: Other Uses

Pine has many other uses! It can be used also for cough, sore throat, sprains and other muscle pains, and many more health cures! It can also be used for many culinary uses, like Pine needle tea, Pine crisps (mmm...), candy, syrup, and much much more!
