The present invention relates to a process of producing a nano-CBD liposome system comprises: (i) preparing a dispersal phase by dissolving CBD in an ethanol solvent in a ratio between mass of CBD:volumn of ethanol solvent as 8:10 by a stirrer at a speed of 300 to 500 rpm and simultaneously heating to a temperature ranging from 40 to 60° C. within 4 to 8 hours； (ii) preparing a liposome carrier consisting of lecithin, olive oil in a ratio by mass of 1:3 mixed in a themostatic bath at a temperature from 40 to 60° C. to ensure that lecithin completely dissolves in oil, stirring homogeneously； (iii) adding the carrier to the dispersal phase in a ratio by mass of 40:60, continuing heating the dispersal phase to a temperature ranging from 40 to 60° C., stirring at a speed of 800 to 1000 rpm for 1 to 2 hours； (iv) cooling the resulting mixture to 25° C. and injecting one volumn of distilled water between 1 and 1.5 L by using hight-frequency nozzles at a frequency of 60 Hz, drop sizes ranging from 10 to 20 μm, injecting capacity of 10 ml/min, with the temperature of distilled water of 25° C., giving a liposome suspension-water solution； (v) homogenizing the mixture of liposome suspension-water solution by injecting through 30 Mpa high pressure homogenizers to obtain a nano-CBD liposome system which is a homogeneous, stable mixture ensured with the particle sizes <；200 nm.
