Thread: How do I make a proper Calea Z extract?

I'm trying to make a Calea Z extract using alcohol.
From what I gather, all I have to do to make the extract is put the leaves in a jar with alcohol (the stronger the better) and leave it for a few weeks, shaking it once a day.
But I just can't find a proper tutorial on evaporating the alcohol afterwards, some say to cook it and let it simmer, but others say you just leave it by a window or have a fan blowing on it, so does heat evaporate it, or cool air?
And appearantly once it evaporates, a sticky substance will sink to the bottom, some say that stuff is garbage, but others say THAT is the extract?
Is it different for different herbs?

I was also wondering how to best consume an extract, is it safe to just drink it? Appearantly smoking wastes alot of it, is that true? And how does one smoke a liquid? (Without having to smoke tabacco or weed)
