Characteristics.

      The prover developed sadness, dry mouth, nausea with great palpitation, dim sight, and great general weakness, increased flow of urine, hot, scalding, with stinging in urethra.
      This last symptom has led to the successful use of Myg. in gonorrhea, chordee, and syphilis.
      The "trembling" observed in the man suggests its use in nervous cases, but the sphere of Myg. in chorea has been developed from the clinical side.
