Plutarch Quaestiones Convivales 1.6.4

[4] Amongst the retainers to Drusus, the Emperor Tiberius’s son, there was a physician that drank down all the court; he, before he sat down, would usually take five or six bitter almonds to prevent the operation of the wine; but whenever he was forbidden that, he knocked under presently, and a single glass dozed him. Some think these almonds have a penetrating, abstersive quality, are able to cleanse the face, and clear it from the common freckles; and therefore, when they are eaten, by their bitterness vellicate and fret the pores, and by that means draw down the ascending vapors from the head. But, in my opinion, a bitter quality is a drier, and consumes moisture; and therefore a bitter taste is the most unpleasant. For, as Plato says, dryness, being an enemy to moisture, unnaturally contracts the spongy and tender nerves of the tongue. And green ulcers are usually drained by bitter injections. Thus Homer: And he guesses well, that what is bitter to the taste is a drier. Besides, the powders women use to dry up their sweat are bitter, and by reason of that quality astringent. This then being certain, it is no wonder that the bitterness of the almonds hinders the operation of the wine, since it dries the inside of the body and keeps the veins from being overcharged; for from their distention and disturbance they say drunkenness proceeds. And this conjecture is much confirmed from that which usually happens to a fox; for if he eats bitter almonds without drinking, his moisture suddenly fails, and it is present death.
