How to Settle Your Stomach, 1695

"Excessive Drinking of Wine"
De conservanda bona valetudine (University of Pennsylvania)

"The Oyl of Wormwood by Decoction, Oyl of Quinces, and Oyl of Mastich, are reckoned by Authors the three Stomach Oyls, for outward Use, to strengthen the Stomach in Vomitings, &c. Two or three drops of the Chymical Oyl, is convenient in a Dose of Stomach Pills, in crapulent Cases, and after a drunken Debauch, to prevent Surfeiting, by cleansing the Stomach of filth and ill Humours.” 

William Westmacott, Historia vegetabilium sacra

Feeling crapulent? Just keep this toolkit of oils on hand for your next drunken debauch. Goodbye, vomitings!

How to Cure a Hangover, c. 78

"Wild and cultivated violets... when made into garlands and placed on the head, relieve hangover and head colds with their scent." 

Pliny the Elder, Natural History (c. 78 AD)

Searching the meadows for wild violets is a drag the morning after a Dionysian toga party. But you will have the prettiest hangover since Roman antiquity.
