ANTIMONIALS, in Medicine, Preparations of Antimony; of Remedies whereof Antimony is the Basis, or principal Ingredient. See ANTIMONY. Antimonials are chiefly of an emetic tendency; though they may be so qualified as to become either Cathartic, or Diaphoretic, or even only Alterative. See EMETIC, CATHARTIC, etc. Dr. Quincy assures, that there are no Medicines in Pharmacy to be compared with these in Maniacal Affections: for that there are no Emetics or Cathartics of any other Tribe that are strong enough for such Patients unless in an Overdose, which might be dangerous. See MANIA. An Antimonial Cup, made either of Glass of Antimony, or of Antimony prepared with Salt-petre, though a Substance indissoluble by the Stomach, will give a strong Cathartic, or Emetic Quality to any Liquor poured into it; without any diminution of its own weight.
