Can you evaporate the alcohol out of a salve or balm? (Making an Oregon Grape Root salve...)

I'd like to make an oregon grape root balm/ointment/topical remedy for my psoriasis. Sadly, it doesn't seem like it extracts well into oil. People usually extract it via alcohol or water. A water extract doesn't seem too shelf-stable and hard to apply.

I worry about extracting into alcohol, though, because the alcohol doesn't seem like a good thing to put on psoriasis. We also don't have alcohol in our house other than isopropyl alcohol and hand sanitizer (ethyl alcohol + hydrogen peroxide + coconut oil + Glycerol). But, if I extracted the oregon grape root into alcohol and then added oil and maybe beeswax, and let it heat up or just evaporate, would the drying properties of the alcohol go away, but the beneficial oregon grape root stuff stay?

I fear that I (A) don't know enough about alcohol's properties and therefore am waaay off the mark, and (B) I'm confused about balm/salve making with an alcohol extract. So, please set me straight!

And, if you can think of another way to make an effective, shelf-stable oregon grape root topical concoction, I would love to hear about it!

Thank you!!

Experiment and see!

You probably want to avoid heat though, as it might affect the ingredients. In a chem lab you would achieve this by lowering the pressure to encourage evaporation.

Nicole, usually if I am not mistaken the alcohol is used as a preservative which works when I use it for a tincture.

Oil is also used as a preservative.

I would try making it without the alcohol and with an oil of your choice.

Make a small amount and see how it works.

Here is a recipe from Mountain Rose Herbs that doesn't call for alcohol.

Please let us know how this turns out.

I don't remember which herbalist recommended it, but it was one of the popular ones.
For an herb that doesn't extract well in oil, she recommended a light coating of alcohol. Just enough for the dried herb to rehydrate a bit. This recipe uses leafy herbs, so I don't know how it translates to roots.
After rehydrating with alcohol overnight, infuse the herbs in the oil for however many weeks is called for.
To evaporate some of the alcohol, gently heat the oil (uncovered)  and keep it uncovered as it cools. This won't remove all of the alcohol, but it supposedly will reduce it.

I made an oil of dried plantain from these instructions. I want to make a salve to use on eczema, but I still hesitate to with the alcohol. It just sounds like it would burn. I've just been making strong teas to soak or spray on my affected areas before applying a non-alcoholic salve.
