Tincture edibles

So I went and bought 6 bottles of tincture from the dispensary today for my edibles, I’ve made edibles for the last few years but have always made my own infused coconut oil or butter or whatever. But I’ve never worked with tincture, I was told you have to decarb it? But isn’t it already decarbed before it’s put in the alcohol to soak? Or does it just need to be sort of “reactivated” I guess? Idk just do I need to heat up the tincture before I add it or can I just add it straight?
