Just because it's cooking in a pot on the stove doesn't mean it's edible

Does making medicine count as crafting?

I'm supposed to be on a self imposed hiatus from crafting till after the new year. (I received a couple of really good books for Christmas and am enjoying reading a little fantasy in the time I would normally spend crafting.)
But... I was running low on my oak tea and since the Live Oak hanging over the fence in the back yard needed some trimming, I figured it was time.
My oak tea is created by boiling small oak branches and leaves till the tea is nice and dark. This time I used 2.5 acidic water from my Kangen water machine http://checkoutkangen.com/index.html that has antibacterial properties. I strained the tea with one of my coffee filters then added witch hazel for added astringency as well help it have a longer shelf life.

What's it for, you ask? I've mostly used it on poison oak (Oak as the cure for poison oak... kind of poetic don't cha think?) but it will work on topical conditions that are blistery and need to be dried up, like severe eczema. This treatment needs to be followed by a salve of some kind after the weepyness is gone. I've used pure lavender, or a blend of willow, mullein, oak, mules ears and st. johns wort with good results.
