§ 2. But as Colocynthis con∣tains as well a watry Salt, as a purging Refine, so some Authors make the Extraction or Tincture with differing Menstruums, that they may have a Tincture comprehend∣ing the whole Virtue of the mixt, thô 'tis true that Ru∣landus, and some others, on∣ly drew it with Spirit of Wine.
§ 3. If therefore you would have it to contain a due pro∣portion of both substances, you may make it thus: ℞ Pulp of Colocynthis cut small lbj put it into an indifferent large Cucurbit on a Sand heat, on which affuse White-wine lbvj. cover the Cucurbit with its Head, which lute well, with a Recipient to its Beak, and make a very gentle Fire under it, for ten or twelve hours. Then strain out the Liquor by pressing, setting it apart: to the feces, return'd into the Gourd, put good S. V. lbvj. or pints, and all the Wine made use of in the former Tincture, which was distilled in the Re∣cipient: cover the Cucurbit with a Vessel of Rencounter, luting it well, and digest in B. M. for twelve hours more, but with a little more heat, afterwards strain forth the Tincture by pressing strongly, which mix with the former Tincture, and filter through brown Paper, so have you the true Tincture of Coloquinti∣da.
§ 4. This Tincture you may, if you so please, reduce to a Rob, or more, thin Ex∣tract, by putting it again in∣to the Cucurbit, and with a gentle Fire in B. M. abstract∣ing the S. V. (which will serve for the like use again) you may afterward in an open Vessel evaporate the superfluous humi∣dity, till it comes to the consi∣stence of a Rob, which you may use as occasion serves, by mixing it with other Extracts or Purging Pills: or you may continue the evaporation till it comes to a sufficient consistency of itself, to form into Pills in like manner.
§ 5. This Extract is excel∣lent to cure Dropsies, and expel Serosities from the most remote parts of the Body, in such Patients where no other Medicines will prevail. It is also a most excellent thing in Diseases of the Joynts, and in Rheumatisms; and won∣derfully prevails against the Gout, whether taken alone, or mixt with other Purgers, especially with that of Rhu∣barb, which qualifies its vio∣lence, and strengthens the
