Solventless extract is commonly called Rosin (pronounced RAWS-IN people) is just an amazing thing. If you know cannabis extracts, you know why you’re here. If not, let us explain.
Rosin is cannabis oil extracted without the use of any solvents whatsoever. Get it? Nada. No butane, propane, no alcohol. All you need to extract solventless rosin is heat + pressure. You can even make it at home using a hair straightener and some parchment paper. Youtube it.
So what we have here is a cannabis extract that is ultimately safe and clean because nothing inorganic was introduced into the process! You’ll find it may leave some more residue on your dabber nail, that’s because it’s not quite as “pure” as extracts made with solvents. There is more plant matter present in rosin so its often a lil bit goopier and darker than shatter or saps.
