This is a cure to MOST curses, spoken or brewed. I do not guarantee that it will work immediately or effectively, but this is the best I've got.

Step 1: Ingredients

I usually use plants and other odd tid bits lying around to make cures. You can use these ingredients or find your own similar ones.
1~ plaster(or any bit of a wall)
2~ feathers(real or fake)
3~ string or thread of any kind
4~ foil or wrapping paper
5~ some form of paper

Step 2: Mixing

Take the plaster and a couple of feathers and place them in the center of the foil. Carefully wrap up the feathers and plaster in the foil, making sure you dont to spill any. Wrap the string around the package 5 times, and tie a tight knot in it. Tuck 4 feathers into the string.

Step 3: Curing

Once you have the package, write on the paper "carsus bo guna ond nuvur rutarn ogoun". Wrap the package in its paper and tie the string around it 3 times, tying it into a tight knot. Tuck 1 feather into the front, and carry it with you for 33 seconds.

If this does not work, find a very smooth rock, and write with a sharpie "guna sporot". Keep this with you for 15 seconds.
