Fuente: WIPO "essential oil or extracts" Methods of manufacturing a cannabinoid product can involve extracting from raw cannabis plant material an extract including cannabinoids and terpenes; separating the extract into a cannabinoid rich fraction and a terpene rich fraction; subjecting the terpene rich fraction to heating in a microwave oven thereby to distil terpene components from the terpene rich fraction; collecting the terpene components. In some embodiments, at least one of the terpene components can be recombined with at least one cannabinoid from the cannabinoid rich fraction. Preferably, the heating step is carried out while subjecting the terpene rich fraction to a vacuum. The cannabinoid rich fraction is processed by crystallisation and recrystallisation to produce a purified acidic cannabinoid component, wherein the purified acidic cannabinoid component can remain carboxylated or be decarboxylated is combined with said at least one terpene component. The recombined cannabinoid product can exhibit characteristics closer to those of the original plant.
