Background: Aldehyde dehydrogenase 2 (ALDH 2) metabolizes acetaldehyde, the major cause of alcohol hangover symptoms. It also detoxifies endogenouscytotoxic aldehydes, such as 4-hydroxynonenal. Oxidative stress promotes lipid peroxidation of cellular membrane, leading to accumulation of reactive aldehydes that contribute to itch signaling via mast cell degranulation and activation of TRPA1 on sensory neuron. A variety of anti-hangover products are available, however, almost none of them has been proven to show enhanced metabolizing capacity of ALDH 2 in a live subject. Objectives: We aimed to test a specific product of interest. Methods: A powder sample of anti-hangover product (KISLip, Pico Entech, Korea) was examined by in vitro & in vivo experiments to measure the amount of NADH formation, generated through catalytic conversion of acetaldehyde. In-vivo examination tested the ethanol and acetaldehyde level in blood of rats with oral infusion of substance before or after ethanol intake. Results: The activities of alcohol dehydrogenase & aldehyde dehydrogenase within the anti-hangover substance were 1.84 unit/g and 0.28 unit/g. The oxidation capacities in rats were dose-dependently increased after substance gavages. Particularly, the cases with oral intake of substance 220 mg/kg after 1hr of ethanol intake have shown more meaningful decreases in acetaldehyde level in blood. Conclusion: Oral intake of anti-hangover substance potentially enhanced ALDH 2 capacity within circulation

Background: Aldehyde dehydrogenase 2 (ALDH 2) metabolizes acetaldehyde, the major cause of alcohol hangover symptoms. It also detoxifies other endogenous aldehydes, such as 2-nonenal. It is an unsaturated aldehyde with an unpleasant greasy and grassy odor. Oxidative stress promotes peroxidation of polyunsaturated fatty acids in cellular membrane, generating 2-nonenal that contribute to aging body odor. A variety of anti-hangover products are available, however, almost none of them has been proven to show enhanced metabolizing capacity of ALDH 2 in a live subject.
