What helps in clearing the liver and blood of alcohol?

Don't binge! A healthy liver will clear alcohol quicker than you may think. Your brain, that's another story. So, do not binge, drink in excess, or think your liver will last forever...
Time. There is no evidence that anything, including more fluids, or herbal meds like milk thistle, clear alcohol any more quickly. The liver metabolizes about one drink per hour, or about 10 mg% of alcohol per hour. If you are intoxicated at 100 mg%, it takes at least 10 hours to get that alcohol out of your body, although toxic effects like hangover, headache etc. May last even longer.
