Heloderma

Gila Monster
The result of the bite is a benumbing paralysis like paralysis agitans or locomotor ataxia. There is no tetanic phase-a condition almost reverse in objective symptoms to Hydrocy acid or Strychnia. The most unusual action of the drug is noted upon the eye of the mouse. The eyeball becomes more prominent and the cornea opacities. The exophthalmus is due to the pressure of the blood behind the eyeball (Boyd). Homeopathically, it is indicated in many forms of disease characterized by great coldness-"arctic" coldness.

Characteristics
The information we possess of the action of Heloderma is contained in vols. v. to xi. of Hom. Recorder, including some remarkable and important provings by Dr. R. Boocock.
