I just went through a bunch of old posts on here about propolis tincture, but since most are around 8 years old, I figured I'd bring it up again. On Bakersdozen's recommendation I purchased Petra Ahnert's book "Beehive Alchemy", and I love it so much I'm reading it cover to cover. I've been wanting to make some propolis tincture, and her recipe calls for 95% grain alcohol, which is illegal in my state. I might be able to get some online (not sure whether that's legal or not), but if I can't, what would be a good substitute?
The book also recommends making the tincture into an oil, and from there into a salve, but I saw on the older posts that some of you seem to be using the tincture straight up. Can both preparations be used in the same ways? Why go to the trouble of the salve if the tincture does the job? Or is it just a matter of preference?
