Ok, so I finally got around to pressure cooking some roots.
I washed and then mostly dried them, then they went in the freezer for over a week. Pulled them out yesterday, chopped up a handful with scissors and put them in a jar with oil. I did not pack the roots in and used enough oil to cover them a few mm's deep.
Ok, so... WOW! No, seriously, this is rather amazing.
It has completely removed most of my pain, leaving only a the deep pain in my hip. Verrry nice.
I applied it last night around 8pm, and the pain is still much reduced. Very nice indeed.
About 45 minutes at 15psi, then slowly turning the heat down over 15 minutes before turning off completely.
The lid vacuum sealed and the jar sat on the counter until it cooled down.
I used a garlic press to get the oil from the root insides for the initial test.
Today I used a wheat grass, hand-crank juicer to press the rest of the roots.
Any suggestions on a simple, low waste method to filter out the root bits? I was thinking cheesecloth, but it would absorb too much oil?
