This is a quest that dates far into the dim & distant past; while I'm certainly not a classicist(!), I know this was an issue that vexed the minds of the ancients! For instance, the Greeks believed you wouldn't get a hangover next day if you wore a garland of parsley on your head while you were out drinking the night before. Hmmm....

In mediaeval times there was very little, if any, distinction made between "receipts" for food & medicines; the two are generally found together. There are more remedies for hangover than there are for pottage (the staple "whatever's on hand" stew of the average person's diet)! There's one that calls for raw eels and bitter almonds ground into a paste(yum!), beer seethed with fennel and cabbage, and any number of herbal decoctions designed to aid in "dispelling of the wind"!

The search for the perfect hangover cure would appear to be as eternal as that for World Peace, and just as difficult to find!
