Ingredients or materials as extracted

  • Prop: A slate-blue amorphous powder, insoluble in ■\\-ater, soluble in hydrochloric acid ; the solution precipitates both with ferrocyanide and ferricyanide of potassium, more abundantly with the latter (showing that both proto- and per-salt are present) ; wlien treated with tartaric acid and an excess of am- monia, and subsequently with the solution of ammonio-sulphate of magnesium, it lets fall a crj^stalline precipitate

Method as extracted

  1. Grind according to the source passage: A slate-blue amorphous powder, insoluble in ■\\-ater, soluble in hydrochloric acid ; the solution precipitates both with ferrocyanide and ferricyanide of potassium, more abundantly with the latter (showing that both proto- and per-salt are present) ; wlien treated with tartaric acid and an excess of am- monia, and subsequently with the solution of ammonio-sulphate of magnesium, it lets fall a crj^stalline precipitate, indicating phosphoric acid. (For explanation of this test, see Appendix, under solution of Ammonio-sulphate of Magnesium.) If digested in hydrochloric acid with pure copper foil, a dark deposit does not form on the metal (absence of arsenic). Thirty grains, dissolved in hydrochloric acid, continue to give a blue precipitate with ferricyanide of j)otassiura until 279 grain-measures of the volumetric solution of bichromate of potassium have been added. {See Ajspendix, Vol.

Live editorial status

This record was published without a human-review gate by site policy. Automated flags at publication: no primary ingredient taxon link, title ingredient mismatch, not marked promotable, critical hazard archive only. Publication makes the source extraction inspectable; it does not verify identity, completeness, efficacy or safety.

Modern safety boundary

Toxic / do not self-use

Do not self-use. The record remains public for historical, botanical and hazard research.

  • Unreviewed automated import: this record is public for live editorial inspection and has not passed manual identity, formula or safety review.
  • Historical formula: ingredient identity, strength, contamination risk and terminology may differ from modern practice.
  • Do not use this record as dosage or treatment guidance. Every ingredient, route and contraindication requires qualified editorial verification.
  • The historical use wording does not establish modern clinical effectiveness.
  • Automated review flags: toxic metal or mineral, corrosive or toxic chemical.

Primary wording. Visible interpretation. No borrowed certainty.

The public record separates the historical passage, structured preparation data, use relationship and modern safety boundary. Same-plant context is presented as context, never as proof that this preparation was intended for that use.
