The present study was performed to evaluate the effect of medicinal plant extract on relieving hangovers in mice administered alcohol. The animals were divided into three groups. Each group was treated with fermented plant extract, non-fermented plant extract, or water 30 min after consuming ethanol (2 mL/kg). A locomotor activity test showed that all groups had decreased motor activity until 40 min after plant extract administration. The mice treated with water had lower motor activity until 100 min post-administration. However, the group treated with non-fermented plant extract showed increased motor activity 40 min post-administration, and the higher activity level was maintained until 120 min post-administration. The animals treated with fermented plant extract had a level of motor activity between those of the groups treated with water or non-fermented plant extract. Blood was collected from each mouse 120 min post-administration and aldehyde concentration was measured. The group treated with non-fermented plant extract had a significantly higher (p < 0.05) aldehyde concentration than the other groups. These results demonstrate that the non-fermented medicinal plant extract helped alleviate hangovers 40 min after administration by reducing aldehyde concentrations in the blood.

This study investigated the effects of mulberry fruit extract on antioxidant activities and the alleviation of an alcoholinduced hangover, which was measured with alcohol dehydrogenase(ADH) enzyme activity. The antioxidative capacity of each mulberry extract was measured by total phenolic compounds, electron donating ability, superoxide dismutase-like ability, thiobarbituric acid reactive substances, and nitrite scavenging ability. The 60% methanol extract yielded the highest total phenolic compounds. The electron donating ability of the 40% ethanol and 40% methanol extracts were 68% and 67%, respectively. The superoxide dismutase-like abilities of the 40% methanol and 40% ethanol extracts were 30% and 28%, respectively, when extracts were assayed at 2.5 mg/$m\ell$. The nitrite scavenging ability of the 60% ethanol and 40% methanol extracts were 98% and 97%, respectively. The 60% ethanol extract yielded the highest ADH.

This study was conducted to investigate if the supplement formula may improve alcohol metabolism in healthy adult men. In a double-blinded, randomized, crossover study, subjects were administrated yeast extract mixtures (YEM, n=15), Hovenia dulcis mixtures (HDM, n=15), placebo (PLA, n=15), and control (CON, n=15) in an oral dose followed by one week washout periods. At each visit (0, 1, 2, 3, 4 week), subjects drank 450 mL, 20.1 percent alcohol after administered mixtures. Blood was drawn periodically (0, 0.25, 0.5, 1, 2, 4, 6, 15 hours). Fifteen subjects completed the protocol and were included in the analysis. Plasma ethanol concentration was lower in YEM (10 percent) and the HDM (5 percent) groups. The area under the curves (AUC) and $C_{max}$ for plasma ethanol were significantly decreased only in the YEM group, when compared with the CON group. The AUC and $C_{max}$ for plasma acetaldehyde concentration were significantly decreased in the YEM (45 and 54 percent) and the HDM (35 and 53 percent) groups respectively, when compared with PLA (p<0.01). Together, these findings validate that YEM or HDM improved alcohol metabolism and hangover syndromes, leading to reduce alcohol concentration and acetaldehyde concentration without adverse effects.

Hangover due to alcohol consumption causes social and physical problems. There is a growing interest in edible insects worldwide. We have previously published a new technology to make hard mature silkworm, Bombyx mori, into edible form, steamed and freeze-dried mature silkworm larval powder (SMSP). In this study, AIN-76 or SMSP (0.1 and 1 g/kg rat body weight) containing diets in SD rats were pretreated for 2 weeks, and ethanol (3 g/kg rat body weight) was administered as an oral gavage and sacrificed after 3 hours. As a result, blood alcohol and aldehyde levels were significantly decreased in SMSP fed rats. In addition, liver injury markers, alanine aminotransferase (ALT) and alkaline phosphatase (ALP) were significantly decreased in SMSP group compared to ethanol group. $TNF-{\alpha}$, an inflammatory cytokine, and malondialdehyde (MDA), an oxidative stress marker, also showed a dose-dependent decrease in the group receiving SMSP. Conclusively, consumption of SMSP not only reduced hangover induced by ethanol, but also decreased liver damage, oxidative stress, and inflammatory response.

This study was conducted to certify the effect of aqueous extracts from fifty medicinal plants on the activities of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) in vitro. Each aqueous extract was prepared by combining one-part medicinal plants with twenty-parts distilled water at $80^{\circ}C$ for 8 h. Among the fifty medicinal plants, Allium sativum L. and Cinnamomum cassia Presl were regarded as an effective anti-hangover substance. Allium sativum L. extract increased ALDH activity more than 2 times compared with ADH activity, enhancing the acetaldehyde degradation. Cinnamomum cassia Presl extract dramatically inhibited ADH activity compared with ALDH activity, thus potently decreasing the acetaldehyde formation. ADH and ALDH activities were proportionally inhibited according to the increased concentration of Cinnamomum cassia Presl extract. The aqueous extract of Cinnamomum cassia Presl at a concentration of $45.33{\mu}g/mL$ inhibited ADH activity by 52.8% and ALDH activity by 11.0%.

Objectives : Alcohol hangover is a common phenomenon which basically occurs after heavy drinking. Moreover, heavy alcohol consumption leads to acute and chronic diseases. We investigated the effect of herbal mixture (SJ) on alcohol metabolism in serum or/and liver. Methods : 5W-old Sprague Dawley rats were used for the study. To overnight fasted rats, 0.9% saline or SJ extract was administrated per os before alcohol treatment. Then, 40% alcohol was orally administrated to all rats in 30 mins. Ethanol, acetaldehyde concentrations, alcohol dehydrogenase (ADH), acetaldehyde dehydrogenase (ALDH) activities were measured by assay kits. Aspartate aminotransferase (AST) and alanine transaminase (ALT) were measured by analyzer. Results : Ethanol and acetaldehyde concentrations lowered in SJ groups compared with CON group. Especially, acetaldehyde concentration significantly decreased in SJ groups compared with CON group. AST and ALT levels tended to increase in SJ groups compared with CON group but there was no significant difference between CON group and SJ groups. ADH activity in serum was higher in SJ groups than CON group but no significant difference in liver. ALDH activity in both serum and liver showed significantly increased in SJ groups compared with CON group. Conclusions : Treatment of SJ extract showed not only reducing concentration of alcohol and acetaldehyde but also increasing activities of ADH and ALDH. These results suggest SJ may influence in alcohol metabolism via control of metabolic enzyme activities and metabolite. Therefore, SJ, herbal mixture, might have a function of preventing hangover after drinking alcohol.

To develop an effective anti-hangover product, hot-water extracts of 25 medicinal herbs were screened for inhibition or activation of alcohol dehydrogenase(ADH) and acetaldehyde dehydrogenase(ALDH), and 12 herbs were selected for further study. Chosen medicinal herb extracts(CMHEs) were fermented by Lactobacillus delbruechii subspecies lactis for 10 days at $35^{\circ}C$ after saccharification with nuruk(malt inoculated by 5 types of microbs) for 72 hours at $35^{\circ}C$ and both CMHEs and fermented CMHEs(FCMHEs) were explored for anti-hangover effects in vitro. We found significant ADH inhibition by hot-water extracts of Pueraria thunbergiana, Hovenia dulcis Thunb, Lycium chinense, Glycyrrhiza uralensis, Acanthopanax sessiliflorus, Liriope platyphylla, and Ixeris dentata, and significant ALDH activation by extracts of Acanthopanax sessiliflorus, Lycium chinense, Ixeris dentata, and Polypori umbellati of the Polyporaceae. The ADH effects on CMHE and FCMHE were -20.22% and -62.63% of control values, and the ALDH effects 173.20% and 280.17%, respectively. In rats given 20%(v/v) alcohol(15 mL/kg), FCMHEs significantly decreased blood acetaldehyde concentrations on 3 hours after ethanol administration, in a dose-dependent manner(p<0.05). Notably, blood acetaldehyde concentrations were markedly reduced in animals given FCMHEs(400 mg/kg) compared to levels seen in rats receiving CADB(commercial alcohol detoxification beverage). Thus, anti-hangover effects were promoted by fermentation of certain medicinal herb extracts.

This study was performed to investigate the effect of fermented Hovenia dulcis Thunb fruit water extract on biomarkers for acute (a) ethanol-induced hangover and chronic (c) ethanol-induced liver injury in rats. For acute ethanol-induced hangover, the rats were administered distilled water (D.W., 10 mL/kg body wt.), Hovenia dulcis Thunb fruit water extract (HWE, 400 mg/10 mL/kg body wt.) and fermented HWE (FHWE, 400 mg/10 mL/kg body wt.), respectively, before 40% ethanol (5 g/kg body wt.) was administered. For chronic ethanol-induced liver injury, the rats were randomly divided into the normal control (cNC), ethanol (cET), cET-HWE and cET-FHWE groups. The cNC and cET groups were administered D.W. (10 mL/kg body wt.) before 40% alcohol (5 g/kg body wt.) was administrered for 21 days. The cET-HWE and cET-FHWE groups were administered HWE (400 mg/10 mL/kg body wt.) and FHWE (400 mg/10 mL/kg body wt.), respectively before 40% ethanol (5 g/kg body wt.) administration for 21 days. For acute ethanol-induced hangover, the serum alcohol and acetaldehyde concentrations were more significantly reduced in the aHWE and aFHWE groups than in the aET group. Moreover, the effect of FHWE was greater than that of HWE. For chronic ethanol-induced liver injury, the serum ethanol, acetaldehyde, ${\gamma}$-glutamyl transpeptidase (${\gamma}$-GTP) levels and the hepatic lipids concentration more significantly dropped in the cET-HWE and cET-FHWE groups than in the cET group. The FHWE administration showed faster recovery of the serum glucose concentration than in the cET and cET-HWE groups. The body weight reduction tended to normalize in the cET-HWE and cET-FHWE groups, which is ideal for chronic ethanol administration. These results suggest that FHWE has a protective effect against ethanol-induced liver damage, as evidenced by its ability to lower the serum ethanol and acetaldehyde concentrations after alcohol administration, and by its ability to decrease the level of ${\gamma}$-GTP and hepatic lipids. FHWE also elevated serum glucose concentration. Therefore, FHWE is effective in reducing ethanol-induced hangover and can play a beneficial role in the treatment of ethanol-induced liver damage as well as body weight reduction.

This study investigates the effects of a hangover beverage (MIX) that contains minerals (highly-salty mineral water, HSMW) and several medicinal plant extracts, on antioxidant and alcohol-metabolizing enzymes in alcohol administered Sprague-Dawley rats. HSMW is pumped from below the sedimentary rock layer of Dadaepo, Busan, South Korea, which is 1,050 m below the land surface; it tastes salty, like sea water. In terms of medicinal plant extracts, the total phenolic and flavonoid contents of Rubus coreanus and Cornus officinalis were measured as being significantly higher than those in Curcuma longa. The results suggest that treatment with MIX significantly increases superoxide dismutase (SOD) activity and DPPH radical scavenging activity. In the 10% HSMW-, for MIX- and company product (CP)-treated groups, the concentration of blood alcohol was significantly reduced 1~5 hr after alcohol loading, compared to that in the control group. In hepatic alcohol-metabolizing enzyme activities, alcohol dehydrogenase (ADH) activity was found to be higher in the MIX- and CP-treated groups than in controls, whereas acetaldehyde dehydrogenase (ALDH) activity was significantly higher in the CP-treated groups than other groups. This study concludes, therefore, that MIX (HSMW) minerals, like as Zn, Ca, Mg, Mn, and others stimulate alcohol-metabolizing enzymes, while the antioxidants of plant extracts prevent the damage otherwise incurred by alcohol toxicity. These results suggest that the hangover beverage (MIX) alleviates alcohol hangover symptoms by stimulating activities related to hepatic alcohol-metabolizing enzymes and antioxidant effects.

This study was designed to investigate the effect of dandelion juice supplementation on attenuation of oxidative stress and hangover after drinking alcohol in healthy college male students. This human trial was conducted by two phase cross over design with two weeks wash out period. The subjects (age $24{\sim}28$ years) were volunteers who had more than 72 g of ethanol drinking capacity. Dandelion group was given dandelion juice 220 mL daily for 7 days. Biochemical markers were determined in blood samples taken at 0 and 150 minutes after administration 72 g of alcohol. The levels of plasma glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, lactate dehydrogenase and bilirubin, the indicators of liver cell damage, were not significantly different between groups. No significant differences in lymphocyte DNA damage level between groups was observed. However, plasma acetaldehyde dehydrogenase (ALDH) and high density lipoprotein cholesterol levels were significantly (p<0.01) increased in dandelion supplemented group compared to that of control group. Furthermore, activities and protein expressions of glutathione-reductase and catalase of erythrocytes were significantly elevated in dandelion supplemented group compared to that of control group. From the above results, it is concluded that dandelion juice supplementation can reduce oxidative stress and hangover syndrome through the elevation of ALDH and antioxidative enzyme system in healthy male adults.
