Argentum cyanatum

Silver cyanide · Mineral

Clarke

Argentum Cyanatum is a minor remedy arising from poisoning cases rather than systematic proving. It is indicated in conditions of severe throat spasm, constriction of the oesophagus, and spasmodic cough where the picture resembles angina pectoris or croup-like suffocation.

Key symptoms

  • Scraping, constriction, and burning sensation in the throat
  • Violent pain in supra-sternal fossa and under manubrium sterni on turning to one side
  • Suffocative attack with short, difficult respiration
  • Constant dry, spasmodic cough allowing only one word at a time
  • Painful cramps in the feet
  • Face and tongue very red

Worse (aggravation)

  • Turning to one side (pain under sternum aggravated)
