Core Keynotes & Hallmark Features
- Anxiety, Restlessness & Fear of Death: Agonizing mental anguish with constant bodily restlessness; drives patient from bed to bed, believes taking medicine is useless because death is inevitable (Boericke, Clarke, Hering, Kent).
- Burning Pains Ameliorated by Heat: Intense, corrosive burning pains as if coals of fire were applied to the parts, distinctly relieved by hot applications and warm drinks (Boericke, Hering).
- Thirst for Small Sips Frequently: Excessive, unquenchable thirst for little sips of cold water at short intervals, which chills or irritates the stomach (Boericke, Kent).
- Midnight Aggravation (1:00 AM to 3:00 AM): Marked aggravation of asthma, diarrhea, gastric pains, restlessness, and fevers immediately after midnight (Clarke, Kent).
- Profound, Rapid Prostration: Sudden sinking of vital strength out of all proportion to the apparent duration of the illness (Boericke, Clarke).
- Acrid, Excoriating & Putrid Discharges: All bodily secretions (coryza, stool, leucorrhea, ulcers) are thin, offensive, cadaveric, and burn the skin over which they flow (Hering, Kent).
Common Clinical Conditions

Frequently Asked Questions
What is the classic keynote triad of Arsenicum Album?
Agonizing mental anxiety with physical restlessness, burning pains ameliorated by external heat, and rapid profound prostration (Boericke, Clarke, Kent).
How does the thirst of Arsenicum Album present?
Intense unquenchable thirst for small quantities of water at frequent intervals, which is often vomited as soon as it reaches the stomach (Boericke, Kent).
What is the typical time of aggravation for Arsenicum Album?
Distinct aggravation after midnight, especially between 1:00 AM and 3:00 AM (Clarke, Kent).
What type of burning pain is relieved by heat in Arsenicum Album?
Burning pains in stomach, skin, ulcerations, and respiratory tract feel like hot coals but are distinctly relieved by hot drinks and hot applications (except headache, which is better by cold) (Boericke, Hering).
How does Arsenicum Album act in acute food poisoning and ptomaine poisoning?
It rapidly controls vomiting, watery offensive diarrhea, stomach burning, cold sweat, and collapse following spoiled meat, stale food, decayed fish, or ice cream (Clarke, Hering).
How is Arsenicum Album differentiated from Phosphorus and Apis Mellifica?
Phosphorus craves large quantities of cold water (vomited when warm) and is worse lying on left side; Apis is thirstless with burning-stinging aggravated by heat; Arsenicum drinks small sips often and burning is relieved by heat (Boericke, Kent).
What modalities characterize Arsenicum Album?
Worse from midnight (1-2 AM), cold drinks, cold air, and lying on affected side; better from heat in general, hot drinks, and head elevated (Boericke, Hering, Kent).
Which remedies are complementary to Arsenicum Album?
Phosphorus, Allium Sativa, Rhus Tox, Carbo Veg, and Sulphur (Boericke, Clarke).
