General Information

Arsenic is a toxic chemical element, historically used as a poison. It is safe to use with infants through to the elderly when prepared in homeopathic potencies. Those who need Arsenicum are prone to hypochondriasis and are intolerant of untidiness and disorder. They are anxious, critical, and restless, and dislike being alone but may be irritable with company. Restlessness may be followed by exhaustion which is out of proportion to their illness. They fear illness and disease, death, and being alone. Discharges tend to be acrid and burning. Burning pains paradoxically feel better for heat (except the headache which is better for cold applications). Thirst is for sips of warm drinks but cold drinks worsen. Symptoms worsen between midnight and 2 AM.
