Times of celebration are often also times of over-indulgence and subsequent suffering. Who would not know, for instance, how a hangover can spoil one’s pleasure at the start of a new year? But where is the research that addresses this problem? Scientists seem to be cynically devoid of sympathy for the hangover-victim – well, not all scientists.

During the course of my research-career, I must have conducted well over 60 clinical trials, but none was remotely as entertaining as the one my Exeter-team did several years ago to test whether an artichoke extract is effective in preventing the signs and symptoms of alcohol-induced hangover.

We recruited healthy adult volunteers from our own ranks to participate in a randomized double-blind crossover trial. Participants received either 3 capsules of commercially available standardized artichoke extract or indistinguishable, inert placebo capsules immediately before and after alcohol exposure. After a 1-week washout period the volunteers received the opposite treatment. Each participant predefined the type and amount of alcoholic beverage that would give him/her a hangover and ate the same meal before commencing alcohol consumption on the two study days. The primary outcome measure was the difference in hangover severity scores between the artichoke extract and placebo interventions. Secondary outcome measures were differences between the interventions in scores using a mood profile questionnaire and cognitive performance tests administered 1 hour before and 10 hours after alcohol exposure.

The mean number of alcohol units consumed per person during treatment with artichoke extract and placebo were  10.7 and 10.5 respectively, equivalent to 1.2 g of alcohol per kilogram body weight. The volume of non-alcoholic drink consumed and the duration of sleep after the binge were similar during the artichoke extract and placebo interventions. The hangovers we experienced the mornings after our alcohol exposure were monumental but unaffected by the treatments. None of the outcome measures differed significantly between interventions. Adverse events of the treatment were rare and were mild and transient. Our results therefore suggested that artichoke extract is not effective in preventing the signs and symptoms of alcohol-induced hangover.

While it was great fun to obtain ethic’s approval and run this trial, the results of our two binges in the name of science were, of course, a disappointment. As diligent researchers we felt we had to do a little more for the poor victims of over-indulgence.

We thus decided to conduct a systematic review aimed at assessing the clinical evidence on the effectiveness of any medical intervention for preventing or treating alcohol hangover. We conducted systematic searches to identify all RCTs of any medical intervention for preventing or treating alcohol hangover. Fifteen potentially relevant trials were found. Seven publications failed to meet all inclusion criteria. Eight RCTs assessing 8 different interventions were reviewed. The agents tested were propranolol, tropisetron, tolfenamic acid, fructose or glucose as well as the dietary supplements Borago officinalis (borage), Cynara scolymus (artichoke), Opuntia ficus-indica (prickly pear), and a yeast based preparation. All studies were double blind. Significant intergroup differences for overall symptom scores and individual symptoms were reported only for tolfenamic acid, gamma linolenic acid from borage, and a yeast based preparation.

We concluded that the most effective way to avoid the symptoms of alcohol induced hangover is to practise abstinence or moderation.

WISE WORDS PERHAPS, BUT EASIER SAID THAN DONE, I’M SURE.

  • I have had satisfactory (not miraculous) results with a large glass (16 oz) of water and two aspirin before bed. Only a slight feeling of malaise this morning after a highly celebratory evening–half a bottle of champagne and a couple of beers plus a shot of Grand Marnier, quite a lot for a 120 lb woman over 60 (much more than customary at any rate). Cheers!

    HAPPY NEW YEAR!

    Not only easier said than done, but also doesn’t involve anyone selling anything.
