feverfew is said to be "good for such as be melancholike, sad, pensive, and without speech."
"Chapters in the History of the Insane in the British Isles"
Daniel Hack Tuke
At the time when a medimnus of wheat was sold in the city for one thousand drachmas, and men were forced to live on the feverfew growing round the citadel, and to boil down shoes and oil-bags for their food, he, carousing and feasting in the open face of day, then dancing in armor, and making jokes at the enemy, suffered the holy lamp of the goddess to expire for want of oil, and to the chief priestess, who demanded of him the twelfth part of a medimnus of wheat, he sent the like quantity of pepper.
"Plutarch-Lives-of-the-noble-Grecians-and-Romans"
Clough, Arthur Hugh
