      The original name of Platinum was "Platina," being a Spanish word meaning "like silver" (Plata being Spanish for silver).
      The metal was introduced into Europe from South America in the middle of the eighteenth century.
      It is always found in association with other metals, chiefly Rhodium, Osmium, Iridium, Palladium. Hahnemann was the first to think of it as a medicine, and his proving in the Chronic Diseases is the basis of our knowledge of its action.
      One characteristic symptom, either when found alone or in association with other conditions, has led to many cures with Plat. Lost sense of proportion in both ocular and mental vision.
      Objects look small or the patient thinks them small.
      The becomes pride and hauteur in the mental sphere, the patient (generally a woman) looks down on everything and everybody.
      This is a keynote of Ptal. Another is the occurrence of cramps, cramping pains and spasms, developing into convulsions.
      The cramping pains causes numbness and tingling in the parts affected.
      Pains as if nipped, squeezed in a vice, and these pains increase gradually to an acme and then as gradually decline.
      In the rectum this becomes tenesmus, in vagina, vaginismus.
      Another general keynote is the alternation of mental and physical symptoms: as physical symptoms disappear mental symptoms appear, and vice versa.
      Nash cured a case of insanity of some duration with Plat., being led to the remedy by an alternation of the mental symptoms with a pain the whole length of the spine.
      This alternating feature is also seen between one mental state and another: Changing moods, sad and gay alternately, laughs and cries by turns.
      There is also a perverse state: Laughs immoderately, but in the wrong place, laughs at serious things.
      The mental disorder at times takes a homicidal form.
      Jahr cured with Plat. A woman who had an inspiration to kill her child, and Jule Gaudy recorded (Four.
      Belge d’ H., quoted Amer. H., xxii. 314) the case of a woman who was tormented with an almost irresistible impulse to kill her husband, whom she loved passionately, and with whom she was perfectly happy.
      The sight of a knife had an irresistible fascination for her, and she was often obliged to leave the table to free herself from the impulse.
      A few months before, she had lost a child a short time after confinement, which had been followed by profuse and desperately persistent hemorrhage.
      Recovering from this she became restless, irritable, and her whole existence was ruled by this terrible impulse.
      Plat. 6x and 30X relieved and finally cured her.
      Kent (Med. Adv., xxv. 184) records the case of a middle-aged lady, mother of several grown-up daughters, who complained of a peculiar mental symptom: A fear, in the absence of her husband, that he would never return, that he would die, or be run over.
      She wept all the time he was away.
      Kent discovered that she had been treated for uterine displacement, and was then wearing a pessary.
      This was removed.
      Menstrual flow was copious, black, clotted.
      The external genitals were so sensitive that the usual napkin was intolerable.
      Plat. cured the whole case, including the displacement.
      Almost every symptom in this case was a characteristic.
      The sensitiveness of the external genitals is often so great as to make coition impossible.
      Digital examining of such a patient causes great pain.
      The action of Plat. to a large extent center in and radiates from the sexual organs, male and female.
      It corresponds to masturbation before puberty, and also to the effects of masturbation.
