_Bun_ is a plant in _Yaman_ [Yemen], which is planted in _Adar_, and groweth up and is gathered in _Ab_. It is about a cubit high, on a stalk about the thickness of one's thumb. It flowers white, leaving a berry like a small nut, but that sometimes it is broad like a bean; and when it is peeled, parteth in two. The best of it is that which is weighty and yellow; the worst, that which is black. It is hot in the first degree, dry in the second: it is usually reported to be cold and dry, but it is not so; for it is bitter, and whatsoever is bitter is hot. It may be that the scorce is hot, and the Bun it selfe either of equall temperature, or cold in the first degree. That which makes for its coldnesse is its stipticknesse. In summer it is by experience found to conduce to the drying of rheumes, and flegmatick coughes and distillations, and the opening of obstructions, and the provocation of urin. It is now known by the name of _Kohwah_. When it is dried and thoroughly boyled, it allayes the ebullition of the blood, is good against the small poxe and measles, the bloudy pimples; yet causeth vertiginous headheach, and maketh lean much, occasioneth waking, and the Emrods, and asswageth lust, and sometimes breeds melancholly. He that would drink it for livelinesse sake, and to discusse slothfulnesse, and the other properties that we have mentioned, let him use much sweat meates with it, and oyle of pistaccioes, and butter. Some drink it with milk, but it is an error, and such as may bring in danger of the leprosy. Dufour concludes that the coffee beans of commerce are the same as the _bunchum_ (_bunn_) described by Avicenna and the _bunca_ (_bunchum_) of Rhazes. In this he agrees, almost word for word, with Rauwolf, indicating no change in opinion among the learned in a hundred years. Christopher Campen thinks Hippocrates, father of medicine, knew and administered coffee. Robinson, commenting upon the early adoption of coffee into materia medica, charges that it was a mistake on the part of the Arab physicians, and that it originated the prejudice that caused coffee to be regarded as a powerful drug instead of as a simple and refreshing beverage. _Homer, the Bible, and Coffee_ In early Grecian and Roman writings no mention is made of either the coffee plant or the beverage made from the berries. Pierre (Pietro) Delia Valle[28] (1586-1652), however, maintains that the _nepenthe_, which Homer says Helen brought with her out of Egypt, and which she employed as surcease for sorrow, was nothing else but coffee mixed with wine.[29] This is disputed by M. Petit, a well known physician of Paris, who died in 1687. Several later British authors, among them, Sandys, the poet; Burton; and Sir Henry Blount, have suggested the probability of coffee being the "black broth" of the Lacedaemonians.
