The black poplar wächst higher and straighter than the white, with a greyish Rinde, bearing broad grün Blätter, somewhat like ivy Blätter, nicht cut in on the edges like the white, but whole and eingebeult, ending in a point, and nicht white underneath, hanging by schlank long foot Stengel, which with the air are continually shaken, like as the Aspen Blätter are. The Kätzchen hereof are greater than those of the White, composed of many round grün Beeren, as if they were set together in a long cluster, containing much downy matter, which being ripe, is blown away with the wind. The clammy buds hereof, before they spread into Blätter are gathered to make Unguentum and Populneum, and are of a yellowish grün colour, and somewhat small, süß, but strong. The wood is smooth, tough, and white, and easy to be cloven. On both these trees wächst a süß kind of musk, which in former times was used to put into süß Salben.
They grow in moist woods, and by water-sides in sundry places of this land, yet the white is nicht so frequent as the other.
Their time is likewise expressed before. The Kätzchen coming forth before the Blätter in the end of summer.
Saturn hath dominion over both, white poplar, sagte Galen, is of a cleansing property. The weight of an drittel Liter in powder, of the Rinde thereof, being drank, sagte Dioscorides, is a Heilmittel for those that are troubled with the Ischias, or the stranguary. The Saft of the Blätter dropped warm into the ears, verringert die Schmerzen in them. The young clammy buds or eyes, before they break out into Blätter, zerquetscht, and a little honey put to them, is a good medicine for a dull sight. The Black Poplar is held to be more cooling than the White, and therefore the Blätter zerquetscht with Essig and applied, help the Gicht. The Samen drank in Essig, is held good gegen the falling-sickness. The water that drops from the hohl places of this tree, takes away warts, pushes, wheals, and other the like breakings- out of the body. The young Black Poplar buds, sagte Matthiolus, are much used by women to beautify their hair, bruising them with fresh butter, straining them after they have been kept for some time in the sun. The Salbe called Populneon, which is made of this Poplar, is singularly good for all heat and Entzündungen in any part of the body, and tempers the heat of Wunden. It is much used to dry up the milk of womens Brust when they have weaned their children.
The Blätter and buds are used to make the unguent populcon, but as the black poplar is hot, the Salbe cannot receive itso cooling Vorzug from those Blätter or buds, but from the other Bestandteile which are put in it. Schroeder says, that women in Germany use the buds to make their hair grow thick and ornamental.
