BAlsam of Tolu is a Rosin that flows from the Trunks of several Trees, by means of cutting 'em. These Trees are found in great Quantities in a Province of New Spain, which is betwixt Carthagena and Nomen Dei, call'd Tolu. The Inhabitants of those Parts tie at the Bottom of the Tree little Vessels made of black Wax, or else a Calabash, to receive the Balsam; and when this Liquor falls, it hardens, and becomes much about the Consistence and Colour of Flanders Glue newly made.
This Balsam is very scarce in France; but those who want it, procure it from England, where it is very common. Chuse that which is fresh, of a sweet penetrating Smell, like Balm of Gilead; for when it grows stale it is a dry Balsam. The same Virtues are assign'd to this as to other Balsams, but more particularly for internal Uses, this not being in the least apt to vomit.
Balsamum de Tolu is a balsamick resinous Liquor, of a reddish Colour, inclining to that of Gold; being of the Consistence of Turpentine, very clammy, and sticking fast to any thing; when it grows old it grows dry and solid, and will break into Pieces almost like Aloes. It is of a very fragrant and pleasant Smell, reviving the Senses, much resembling the Smell of Lemons and Jessamin Flowers, but stronger, and not so saint and weak. It is more esteem'd than the Balsam of Peru, and reckon'd almost as good as the Balm of Gilead. It attenuates, dissolves, is pectoral and vulnerary. Outwardly it cures old Aches and Pains of the Head and Joints. It stops Catarrhs, helps Defluxions, strengthens the Weakness of the Bowels, discusses Tumours, and cures Contractions. It is us'd in the Tincture, Spirit, and volatile Oil, as those of the Balm of Gilead, &c.
