CHAP. XXVI. Of Ointments.
OIntments are of a more solid consistence then Liniments, and are therefore of more force. Their differences are partly taken from their effects; for some heat, others cool, some dry,* 1.1 and some humect, some cleanse, some corroborate, some waste dead flesh, and o∣thers cicatrize, partly from the variety of colors, partly from the first inventors, as Album Rhasis, D••siccativum rubrum: partly from the number of the simple medicaments whereof they be made, as, Tetrapharmacum, Tripharmacum, or Nutritum: partly from that medicament which is prin∣cipal in the composition; hence are they called, Vnguentum de Lithargyro, de Minio, Diapomph••∣ligos, and such like. They are compounded of herbs, roots, seeds, fruits, metals, and part of Beasts; the juices and other liquid things being consumed away by boiling, as we have said in the Chapter of compound Oils. Herbs, and the parts of them, if they be dry, must be powdred, and also metals; but being green, they are boiled and strained forth, and the juice so pressed is wast∣ed by boiling. Gums and Rosins some are powdred, others being put to some convenient li∣quor are dissolved by fire: So wax is dissolved in the Oil. In the composition of unguents this proportion is usually observed, that for one ounce o•• powder, two ounces of Wax, and eight of oil is added: notwithstanding for that Wax serveth only to the consistence of the Ointment, it is better to leave the quantity to the will of the Apothecary; but he may be more sparing in adding Wax to the ointments in Summer then in winter; for the heat of Summer, drying them, addeth to the consistence: by examples propounded, these common precepts will more plainly appear.
℞. Olei ros. ℥iv. pil. lepor. bol. armen. terrae sigil. an. ʒi. bal. Gallar. an. ʒ ss. tritis terendis, & simul mixtis,* 1.2 addit â cerâ quod sufficit, fiat unguentum Here we must observe, that there be three waies of making ointments: The first is o•• those which are made only by stirring or grinding in the Mortar without any fire, and so is made Ʋnguentum nutritum. The second is, when we dissolve Wax in Oil, Fat, or some such substance with fire: and being all dissolved, we mingle the pow∣ders according to the proportion we noted before. After which manner are made Ʋnguentum Aureum, Basilicon, Diapompholigos, Desiccativum rubrum, Enulatum. The third sort is, when we bruise herbs with a Pestel, and mingle them with Axungie, boiling them together, and then straining them, and the ointment is that which is strained. Therefore let us proceed to explain this by examples.
* 1.3℞. Lythar. auri triti & loti lb ss. olei ros. lb. i. aceti. ros. ℥iv. fiat Ʋnguentum. First, we put the Lytharge into the Mortar, powring in a little Oil, and working it with a Pestil, that it may grow thick, then with the Oil we put a little Vinegar, continually working, until they mingle into one body, now and then between whiles adding sometimes a little Oil, sometimes a little Vinegar, untill the whole be brought to the consistence of an ointment. If of an ointment of this kind thou wouldest make a black plaister, by degrees consume all the Vinegar, so shall the plaster shine and grow black.
* 1.4℞. Cerae citr. ℥vi. olei boni lb. ii. tereb. ℥ii. resin. & coloph. an. ℥i ss. olib. mastich. an. ℥i. croci, ʒi. fiat Ʋnguentum. First, dissolve the Wax with a good part of Oil, then add the Rosin and Colo∣phonie broken small. These being dissolved, take the composition from the fire, and then add the Turpentine, when the whole is somewhat cooled; add the Olibanum and Mastick being finely powdred, then the Saffron, which shall be macerated in the rest of the Oil.
* 1.5Tetrapharmacon is so called, because it is made of four simple medicines, Wax, Rosin, Pitch, Tallow, of each a like quantity, and so equally mixed.
℞. Resin. picis nigr. adip. vituli, & cerae an ℥ii. ss. Olei veteris olivarum maturarum, lb. i. ss. or if you would have it harder, ss. i. that ointment is also called Basilicon, the Wax being cut small and dissolved in Oil, then add the rest of the things, which being dissolved, thou shalt have the desired ointment.
