One of the wonder drugs in Homeopathy which I have used for almost every conceivable clinical entity from Food poisoning to Organophosphorus poisoning and its after effects, to asthma, eczema, fevers of all types is ARSENIC ALB. If any homeopath ventures into practice without this remedy in his medicine chest, he is doomed. I have analyzed this drug in my own unique way and publish the thread below. This drug cuts across all clinical nomenclature and is the most frequently prescribed remedy in my armament.
