Are you making tincture using high % alcohol?
If so, you are 1/2 way through the process of making a full extracted cannabis oil.
You’d need to soak cannabis in 95% alcohol, shake it well,  filtre the plant material out, and then evaporate the alcohol off. 
What remains is a concentrate of cannabinoids (THC, CBD, CBN ect.)
I decarb my cannabis as my first step. This activates it and makes it 10x stronger and completely ready to eat, right from the start.
Finished concentrate can be eaten in (rice grain size) doses or, it can be dabbed on a hot nail through a bong or added to a bowl or a blunt.
It is common to hit 65-90 % THC or CBD in concentrate that is made this way.
10% is industry standard. If you used 100 grams of dried flower and it’s a descent strain (for making concentrate) you can expect to capture 10 grams of concentrate for your efforts. Cost to buy (usually, in my area) is $50 a gram for a standard strain (nothing fancy).
Hope that helps...you’re close with tincture.
