  • Patent number: 10745644
    Abstract: A method for post processing oil extracted from cannabis comprises the steps of placing the oil into a container at a first predetermined temperature for a first predetermined time during which the oil will separate into two parts comprising a high terpene (HT) liquid fraction and a high cannabinoid (HC) crystal fraction, heating the HT and HC fractions under a first predetermined level of vacuum at a second predetermined temperature for a second predetermined time, and heating the HC fraction to a third predetermined temperature for a third predetermined time. The steps further comprise adding a first predetermined quantity of the HT fraction back into the HC fraction to create a first mixture, adding a second predetermined quantity of benign terpenes into the first mixture to create a second mixture, and mixing the second mixture to create a finished mixture.
