356 i Treatise 
Delirioufnefs without a Fever, in the cholera Morbus , 
Dropfy, and Pleurify, in Loofene fifes, Dyfenteries, 
the Gout, and Small-Pox, and againd Worms. But 
nothing is fo excellent, but that too free an Ufe of 
it may be hurtful ; and this Medicine requires the 
fame Cautions in its Adminidration, with Scam- 
mony, and other Catharticks : Yet we mull ac- 
knowledge, that when thus prepared it is lefs ob- 
noxious to the Inconveniencies abovementioned, 
may be prefcribed by the Phyfician more fafely, 
and be taken by the Patient without Difgud. 
We are obliged to the Chy milts for a Tindlure 
of this Drug, and a refinous Extract, improperly 
called its Magiftery . The Tindture is made by dif- 
folving Scammony in Spirit of Wine, and feparat- 
ing the clear Liquor from the Faces, The Extract 
is made by evaporating the Tindture to Half, and 
pouring Water to it, by which Means the Spirit, 
which before kept the Refin fufpended, forfakes it, 
and the refinous Particles fall to the Bottom under 
the Appearance of Turpentine. The Sediment, af- 
ter many Ablutions in Water, is at lad dried in 
the Heat of the Sun. But this Refin purges lefs 
than Scammony in the fame Dofe, yet irritates the 
Intedines more violently, and often inflames them : 
Which we have before obferved of the Refins of 
fome other Catharticks. 
Moreover, others try to corredt Scammony with 
acid Liquors. They either diflolve it in Citron- 
Juice, then drain the Solution, and evaporate to 
the Confidence of an Extract ; or they moiden the 
Powder with Spirit of Sulphur or Vitriol, and dry 
it. But thefe Corrections in fome Meafure dedroy 
its Subdance, and therefore leffen its Efficacy : So 
that it is better to mix it with fome Powders, as in 
the Pulvis Cornachini.
