taken. Hangover severity (based on nine symptoms) and overall<br />
well-being were assessed on a scale (zero to six points, with six<br />
points indicating the worst well-being). Two weeks later, the study<br />
was repeated with the same volunteers except those that were<br />
previously given OFI were given placebo and vice versa.<br />
The researchers found that three of the nine symptoms of hangover<br />
– nausea, dry mouth, and loss of appetite – were signifi cantly<br />
reduced after taking OFI. The average score for well-being the<br />
next morning was 2.75 for volunteers who took OFI and 3.10 for<br />
volunteers who took placebo. The researchers also found that<br />
levels of C-reactive protein were strongly associated with hangover<br />
severity, and C-reactive protein levels were 40 percent higher<br />
in volunteers who took placebo compared with OFI.<br />
“In this randomized, placebo-controlled, crossover trial, we<br />
found hangover symptom severity to be moderately reduced by<br />
an extract of the prickly pear plant, Opuntia fi cus indica,” the<br />
authors write.<br />
