THis Wood is brought from New-Spain, is tender and dry, though heavy, by which it appears to be more Saline than Oyly, and therefore communicates easily its vertue to Water, which it dyes of a yellow-brown colour, in decoction appearing somewhat blewish in the Surface. We have chosen this Wood to show its difference from others; for although it be inodorous & in∣sipid, it is nevertheless endowed with much vertue, and expels pow∣erfully by Urines, whether simply infused in cold Water to drink the colature thereof, or mixt alone with white Wine; or whether a decoction be made thereof, which is very insipid. In this manner Page  310it conduces very much to help those that are troubled with the Stone, Gravel, or stopping of Water. But above all, it is consi∣derable in decoctions against the Pox and Scurvy, for it frees easi∣ly and powerfully the Patient from the venom of these two dis∣eases; and, because this Wood is not to be found every where, we have thought it necessary to teach the manner of its extract, whereby the Artist may regulate himself in all other Woods, which shall be of this kind. Scrape lb vi. of this Wood, and make a decoction with Roots of Resta-bovis, Hundred headed-thistle, or Sea-holy; ana lb iij. and lb i. of Virga-aurea, or Gol∣den-rod in lb xxx. of River or Rain-water, till ½ be consumed: then percolate and express it, and make a second decoction of the cake remaining after the expression in lb xx. of fresh Water, then percolate and strain it, and so continue until the decoction takes no more colour: which done, clarifie all the decoctions, and run them through the bagg, and evaporate it in a slow heat without ebullition, to the consistency of a liquid Extract; to which add the Salt extracted from the remains of your Extraction. This Ex∣tract is an excellent diuretick aperitive Remedy, which may be exhibited from ℈ i. to ʒ i. in Broths, white Wine, or decoction of Lignum Nephriticum, when those which are troubled with Gra∣vel, Stoppings of Water, or Nephritical Colick are in the half Bath: but with this precaution, that they take before and render again a Turpentine Glyster.
