Filings, or Filings rusted with Water, and the difference of the Saline Menstruum, this being Spirit of Salt.
§ 2. Zwelfer Mantissae Spa∣gyricae, par. 1. cap. 3. makes it of the Crocus, with Spirit of Venus, thus: ℞ Crocus Martis Cachecticus q. s. to which affuse Spirit of Venus so much as may over-top it three or four inches: digest in a gen∣tle heat, till the Spirit is im∣bued of a rubicund colour, which decant, and affuse more fresh Spirit, and that so often as need shall require, till the Spirit will be tinged: put all these tinged Spirits together, and in B. M. abstract to an oleaginity. To the remaining thick Matter put Tartarized S. V. and extract a Golden co∣loured Tincture, which abstract in part again, leaving the yel∣low Tincture at bottom.
§ 3. This Golden Tincture of Mars made by either way, is a most excellent thing a∣gainst the Cachexia, Green-sickness in Virgins, and all Obstructions of the Viscera, being taken à gut. xij. ad xxx. or more in any proper Liquor: but this is peculiar to the Tincture of the Crocus, more than to the other Tin∣ctures, that they strengthen (in Dropsies, and other like Diseases) the Bowels more than the other, as Hofman has observed: See § 24. of the former Section.
§ 4. Kesler makes this Tin∣cture of the Crocus with Sal Armoniack; but Quercetanus with A. F. the Preparations of which you may see in our Pharm. Lond. lib. 3. cap. 4. sect. 19, 22.
§ 5. But in making this, and all other Preparations of this kind, you are to take heed, that your acids be not too extream; for so Etmul∣ler, Tom. 2. pag. meâ 606. has advised, by reason that being so prepared and taken into the Body, they little or no∣thing operate. Pari ratione (saith he) Tincturae martiales nimis acidi praeparetae intra corpus assumptae parum aut ni∣hil operantur, si verò cum al∣kalibus aut blandis acidulis praeparentur, suam merentur laudem.
§ 6. Equal to this Tin∣cture of the Crocus, Zwelfer, accounts his Tincture of the Vitriol of Mars, which is pre∣pared from the said Vitriol with Terra foliata Tartari, which is indeed a Medicine of great use, and preferred before most others.
§ 7. There is a preparation of the Crocus with Sp. Vitrioli; but this, saith Hofman, is no∣thing but the Vitriol of Mars
