The primary objective of the study is to test whether the tested Product LACIME Anti-hangover is effective in preventing the signs and symptoms of alcohol-induced hangover (such as headache, impaired memory, depression, anxiety, weakness, trouble sleeping and concentrating, nausea, dizziness, sleepiness, thirsty, dry mouth, sweating, sensitivity to light and sounds, vision problems) in healthy subjects.

LACIME Anti-hangover is a food supplement under the form of a syrup (water/glycerin based) containing plan extracts, each one having choleretic properties.

40 healthy subjects will be tested in a randomized, double-blind, placebo-controlled, crossover trial.

The participants will have to attend the 2 phases of the study during which they will receive in a blind way a product (LACIME Anti-hangover or PLACEBO):

If a participant has received LACIME Anti-hangover for Phase 1, the same participant will receive the PLACEBO for Phase 2 and vice versa.

Inclusion Criteria:

For inclusion in the study subjects must fulfil all the following criteria:

20-30 years old healthy males and females, Body weight (kg): 60 - 80 in man and 60-70 in women, People who consume alcohol occasionally and who already have to deal with hangovers Healthy volunteers who consume alcohol regularly and moderately, Having given their free, informed and express consent in writing Co-operative, informed of the need and duration of the controls which make it possible to achieve full adherence to the protocol in place.

Exclusion Criteria:

Excluded from participating in the study:

Volunteers consuming larger amounts of alcohol (more than 2 glasses of alcohol per day) Volunteers taking medication or food supplements that may affect alcohol metabolism.

Women who are pregnant or breastfeeding or plan to become pregnant during the study Subjects with illnesses which may conflict with the investigator's interpretation, if the subject participated in the study Subject planning to change his/her lifestyle during the study (diet, physical activity, etc.) Smoker Subject participating in another study during the clinical study period.

• At the first medical visit all volunteers will be checked for illegibility, randomized, and sign written informed consent including an obligation that they will not take alcohol within the next week and come to the study site a week later at least 3 hours after the last meal.
• At the second visit, participants will attend the study site, where each will fill Hangover Severity Symptoms (HSS) form, donate blood and urine for initial analysis.

Then participants take the Product LACIME Anti-hangover or PLACEBO and after 1hour will start to consume alcohol during two hours with meal (3 sandwiches with cheese or ham) on each of the 2 study phases.

Drink consumption, the composition and sequence:

300 ml of Brandy (41% vol. alcohol) corresponding to an intake of 123 ml or 99 g of alcohol 300 ml of Champagne (13% vol. alcohol) corresponding to an intake of 40 ml or 32 g of alcohol This will ensure a 100% hangover syndrome and a total intake of 131 g of alcohol (a dose of approximately 2 g / kg).

Such a dose will provide a peak concentration after 1 hour and should allow to determine the alcohol 15 hours after absorption.

Smaller doses are usually not detectable after 10-12 hours. (Jones, 2008).

D2 test, blood sampling and urine sampling under medical control is achieved before alcohol intake.

D2 test, blood sampling and urine sampling under medical control is achieved 1h, 4h and 15h after alcohol consumption.
