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 Pack for a Journey, 1480

Martellus world map, c. 1490

"[A traveler] should carry with him two bags: one very full of patience, the other containing two hundred Venetian ducats, or at least one hundred and fifty... furthermore, he should provision himself with good Lombard cheese, sausages, tongue, and other cured meats of every sort; white biscuits, some cakes of sugar, and various confections, but not a great quantity because they spoil quickly. Above all he should take plenty of fruit syrup, because that is what keeps a man alive in extreme heat; and also ginger syrup to settle his stomach if it is upset by too much vomiting." 

Santo Brasca, Viaggio in Terrasanta (1480)

Airport security may take your fruit syrups, and customs may confiscate your cured meats, but no one can take away your suitcase full of patience.
