      Burt, who made a heroic proving of this remedy, says: "The grand sphere for he use of Dioscorea is among neuroses of the bowels and stomach, where the celiac and umbilical plexuses are in a state of great hyperesthesia, the pain and spasm being unbearable." Hale considers as characteristic: "A constant pain, aggravated at regular intervals by paroxysms of intense suffering." Any kind of colic or neuralgia with these characteristics may indicate Dios., which stands in the highest rank among stomach and abdominal remedies, with important actions in many other spheres.
      Dioscorea causes pain in the bowels, spasmodic, twisting, writhing, drawing, lancinating, pulsating, burning.
      Pains radiate upwards and downwards.

      Pains worse at meals, better moving about, cannot sit still.
      Seminal emissions (passive) with weakness of knees.
      According to Cushing’s proving the primary effect of Dios. was to cause strong-smelling perspiration of the genitals, constant excitement with strong and frequent erections day and night, amorous dreams with emissions.
      Afterwards came relaxed genitals, absence of desire, and emissions without erections.
      In the female sphere it has frequently cured dysmenorrhoea, uterine colic, and after-pains, also gastric disorders during pregnancy and the menses.

      Dios. resembles Coloc. in colicky pains, but differs in the Conditions: while Coloc. has better bending double and worse by motion, Dios. has better by stretching out and by moving about.
      Some of the symptoms of Dios. are worse, others are better by touch and pressure.
