Do you know how to make Salvia extracts?
This is something that I have never looked into in any depth, because I have never personally felt any need.
Interestingly, I get asked this question a lot from people who have yet to try Salvia. - To which I would say that extracts may be of particular use if you turn out to be a bit of a ‘Salvia hardhead’ but otherwise you should maybe see how you get on with untreated leaf first.
As to techniques for making extracts, I have no first hand experience. I include some brief reference to extracts via the introduction page>, but apart from that you’ll find plenty of advice on the Internet of course, much of it no doubt contradictory (such is the nature of the beast). But I couldn’t advise you as to which one is the most reliable, easiest or the best.
