Their Virtues.

These Powers are abundantly surpassing in virtue any other preparation of Scurvy grass whatsoever, and as I formerly told you, they were originally prepared by me in Holland,and presented to both Ʋniversities, which for goodness, strength, and pleasantness of Tast were allow∣ed to stand parallel with, nay some were of Opinion that they clearly out striped those of the greatest Pretenders in Europe, the Modus Operandi of which I never so plainly before communicated; but I have now done it on purpose to be serviceable to the Ingenious, and to de∣stroy the use of that sophisticated Spirit sold, which is made in six or eight hours time, with a little Malt Spi∣rit and Scurvey grass, made burning and sharp in Tast with Horse-radish, but this Spirit is not to be valued; for tis impossible to take out the specifick virtue of the Grass without an higher exaltation; and the reason why the sick are often disappointed in their Expectation is this, the slight preparation that many Pretenders make, for the Grass will not so easily give forth its central Virtue, for this, when truly obtained, hath an excellent effect in relieving from many Diseases, and principally the

Scurvey, because the herb hath a signature against the Disease, it helps the Liver, Spleen, and other Viscera in their Defects; it fortifies the vital Spirits and gives Cir∣culation to the Blood, its internal texture being made up of a Volatile Armoniack and Vinor Essence united with a vital medicinal Crasis, and as the Learned Physici∣cians allow, as well Modern as Ancient which that worthy Mrs. Experience daily confirms, there is no herb in the Vegetable Kingdom of a more Specifick Virtue in curing the Scurvey, than the aforesaid Scur∣vey-grass, for tis a great Abstersive and so dissolves and dissipates congealed humours, for by its Alkalisated nature it opens and mundifies, and by it's Vinor are the Venoms imbibed and destroyed, so by its carrying off all the Saline trude humours which are the Original Cause of the Scur∣vey, whether proceeding from living in crude moist and foggy Airs, where the Sea-damps are, or from raw sowr fruits, or exceeding Salt Fish or Flesh, as is plainly demon∣strated by the incident of the Diseaseupon Seafaring-per∣sons, especially such as use long Voiages, it sweetens the blood; this Spirit doth not only cure this Disease in all its Sym∣ptoms, but also prevents it from approaching in such as take it for prevention sake, therefore in brief, what we have to say is, that it is indued with virtue to give Sa∣nity to the principal Faculties, and is a certain speci∣fick both at Sea and Land where this popular Disease Reigns; as also in Camps and Armies against the Chill∣bane and Rot, which are usually there, by which men dye as Chore-sheep.
