## Keynote Indications
Ars-h. was used by Drysdale as a substitute for Arsenic in the collapse stage of cholera. 
The symptoms set in suddenly but developed slowly. In poisoning cases, death often took place in the second 
week and one person, who recovered, suffered seven weeks. 
Though like Ars. in general symptoms, the gas has symptoms of its own. The general action is the same, but 
more accentuated. A striking case of sudden suppression of menses was cured with Ars-h. after failure of Ars. 
Anemia. Anxiety, despair. Hematuria with general blood disorganization. Hemor rhages from mucus 
membranes. Urine sup pressed, followed by vomiting. The prepuce and glans of penis are covered with 
pustules and round superficial ulcers.
