It's anise hyssop not licorice or anise, the anise flavor is subtle.
Distilling essential oils depends on having a still. Even the smallest home distillation equipment is pretty expensive (by my limited budget standards anyway). I have two, neither of which is perfectly satisfactory.
advertises makes essential oils in 6 min. It does work in 6 min (after the equipment is frozen over night) in the microwave. However, I could never get it to produce any
actual essential oil. What it produces is a pretty low quality dilute hydrosol, which is the essential oil still mixed with water. It is quick and uses very little power, but the product is really not high enough quality for me.
Then I have a little stove top still I got a few years ago from Edmunds Scientific for about $80 (cheap !). But it looks like they are not carrying it any more. What it produces is also hydrosol, but much higher quality, less dilute. It is good enough for my purposes, though I could not sell it as essential oil. But it takes hours of boiling on the stove to produce it and makes me feel very guilty about the power I am using.
So I am still in the market for a good small home distiller....
The stove top one I have from a couple cups of plant products makes maybe a half ounce of hydrosol. I know if I could get the actual essential oil from that it would be MAYBE a quarter teaspoon full.
