The pseudo-ginseng stem and leaf compound is developed firstly, the pseudo-ginseng stem and leaf compound is obtained by taking four specific medicinal and edible materials including pseudo-ginseng stems and leaves, gastrodia elata, poria cocos and spina date seeds as raw materials through alcohol extraction, and the four raw materials are matched with one another and have a potential mutual promotion effect in the aspect of improving endogenous gamma-aminobutyric acid and melatonin. The pseudo-ginseng stem and leaf compound is creatively combined with gamma-aminobutyric acid, L-theanine and a licorice extract for use, and the four components cooperate with each other, so that the effect of improving the levels of endogenous gamma-aminobutyric acid and endogenous melatonin is further improved.
