The present disclosure belongs to the technical field of health care products or foods and provides the use of a ginseng alcohol extract in sleep-promoting health care products or foods. Through analysis utilizing DAM2 drosophila behavior monitoring system, it is found that the ginseng alcohol extract can increase total sleep duration of normal and sleep deprived drosophilae, and relieve sleep rhythm disorder caused by sleep deprivation. Through a climbing experiment, it is found that the ginseng alcohol extract can improve the climbing ability of normal and sleep deprived drosophilae. The ginseng alcohol extract, on the one hand, improves the quality of sleep to protect the steady state of sleep rhythm, and on the other hand, increases the motive ability after sleep. The ginseng alcohol extract of the present disclosure is intended to be used to sleep-promoting health care products or healthy foods and improve the quality of sleep.
