I found this recipe for you
here.
What you need:
Uncoated aspirin
70% alcohol
Witch Hazel
A measuring cup/bottle
2 bottles used to shake mixtures
1 8oz or more bottle/container to keep finished product
What you do:
1. Pour 5.5oz of 70% alcohol into one bottle.
2. Drop 18 uncoated aspirins into the alcohol. Cap bottle and shake.
3. Pour 2.5oz of witch hazel into the second bottle.
4. Drop 8 uncoated aspirins into the witch hazel. Cap bottle and shake.
5. Wait awhile (30 minutes to a whole day) for the aspirins to dissolve in the liquids. Shake periodically to help dissolve aspirin and mix. NOTE: not all of the aspirin will dissolve. That’s ok- some of it never will.
6. Now combine both the alcohol and witch hazel mixtures together into one bottle. Make sure you shake it up before you pour them out so you also get the aspirin residue into the new bottle.
This last bottle is your
Tendskin! Use 1-2 times a day. Reduce usage if you experience dryness or flaking or irritation. DO NOT USE IF YOU ARE ALLERGIC TO ASPIRIN. Make sure you shake it well before each use.

I've never tried this personally but have always thought about trying it out. From reading this over, though, I would try crushing the aspirin into powder with a mortar and pestle before adding it to the liquid - I suspect it would dissolve much more fully. I also have no idea why they tell you to use two different bottles, that seems kind of unnecessary, but who knows? Let us know how it goes!
