Remember the brown tea-like water you poured off the first soaking of acorns? Well, don’t throw it out just yet. Even though it seems like we’re brewing up some kind of medieval potion, crushed acorns and hot water can provide a great remedy for inflamed and irritated skin, as well as toothaches. You can use the first water you pour off from the process of soaking described above. Or you can make a liquid that’s more concentrated by boiling crushed acorns (shells and all) in a pot of water. A handful of crushed acorns in one pint of water will make a small batch of strong medicinal fluid. Soak a clean cloth in this dark brown water, and apply the wet cloth to rashes, ingrown toenails, hemorrhoids, and any other inflamed skin ailment. Leave the cloth in place, and repeat this treatment as needed. For tooth troubles, simply swish the bitter water in your mouth, holding it in there as long as you can. Repeat as needed, but do not swallow, as this acidic water will give you an upset stomach.
