CBD rosin is a special type of hemp concentrate that's vastly different from 'regular' extracts. Technically it isn't an extract at all — it doesn't use harsh solvents, so there's no extraction involved in making it.
Instead CBD rosin is produced by gently heating and pressurizing hemp flower. There are several advantages to this method. For starters, CBD rosin is truly full spectrum, with a perfect blend of CBD, THC, CBG, CBN, CBDa, THCa, terpenes, flavonoids, and more. It's also truly pure, free from any residual solvents or chemical byproducts whatsoever.
