Collect about 50 leaves, wash them thoroughly, grind them up in a blender, but not very thinly, only for just a few seconds. Place the ground leaves into a wide pot and add just enough water to cover them.

Place the pot on the stove at low heat for 30 minutes. Do not let it boil, because you'll destroy all the good stuff in it. Stir every 15 minutes until the water gets a dark-brown color. Pour the substance while still hot into another pot through a strainer. Almost none or very little plant material should get through it.

Try to squeeze as much water as you can while the plant is in the strainer. This solution contains all the core elements of Wild Lettuce, especially the pain killing essence. But it's not concentrated enough. In order to obtain this essence we you should warm it over low heat again until the water is vaporized, basically dehydrating the solution until it becomes a paste like this.

Be careful at the end when there is little water left, you should not burn the extract at bottom of the pot.

What you should have now here is pure Wild Lettuce Extract. Pour it in a small glass container and put it in your medicinal cabinet for when you'll need it.
