Arsenicum hydrogenisatum
Arsine (arsenic trihydride) · Mineral
Arsenicum Hydrogenisatum is indicated in conditions of severe blood disorganisation and collapse, resembling the collapse stage of cholera or yellow fever. It suits patients with haematuria, sudden suppression of menses, and gradual darkening of the skin, sharing the general prostration of Arsenicum but with distinct blood-affecting properties.
Key symptoms
- General blood disorganisation with haematuria and haemorrhages from mucous membranes
- Urine suppressed followed by vomiting; collapse and great prostration
- Sudden suppression of menses with internal chills and tearing pains in hands and feet
- Violent vertigo on going upstairs; eyes sunken with broad blue circles
- Skin becomes dark brown; deadness from hands to mid-forearm and feet to knees
- Constipation with feeling of weight and stiffness in abdomen
- Tormenting hiccough with oversensitive epigastrium
Worse (aggravation)
- Cold and damp; chilliness on slight exposure or change of temperature

Clinical
Collapse of cholera. Hiccough. Suppressed menses. Yellow fever.
Characteristics
Arsen. hydro. was used by Drysdale as a substitute for Arsenic in the collapse stage of cholera. The symptoms set in suddenly but develop slowly. In poisoning cases death often took place in the second week, and one person, who recovered, suffered seven weeks. Though like Ars. alb. in general symptoms, the gas has symptoms of its own. A striking case of sudden suppression of menses was cured with it after failure of Ars. a.
Relations
Compare: Arsen. alb. antidoted by: Am. acet. (breathing); Sinapisms (breathing); Nux v. (fever); drinks containing sulphuretted hydrogen.
