The cannabis is then removed; the liquid is filtered and the alcohol purged from the extracted material. Preparation of Microspheres by Solvent Extraction Method. As the water heats up, the steam travels upwards into the plant flask, separating the oil vapors that contain CBD. For aromatic plants, hydro water and steam distillation), hydrolytic maceration followed by distillation, expression and effleurage (cold fat extraction) may be employed. Cold cannabis extraction methods result in the creation of concentrates like hash, kief, wax, shatter, crumble, and taffy.
