Argentum nitricum
Silver nitrate · Silver nitrate, hellstone, devil’s stone, lunar caustic · Mineral
Argentum nit. is best suited to people who are extroverted, cheerful, and impressionable. Suggestible and impulsive, they may have difficulty in controlling their far-ranging minds and emotions, and readily laugh, cry, lose their tempers, or become anxious. They may be nervous, phobic, and superstitious. Motivated people who think, talk, and act rapidly, they are always in a hurry, and are frequently to be found in careers that require quick thinking and a good memory, or where the emphasis is on performance.
Typical physical symptoms include a “sensitive” digestion, a lack of physical control, with awkwardness and tremors, and a tendency to feel the heat. Argentum nit. is used for certain nervous, mental, and digestive problems where these key physical and mental symptoms are evident.

Characteristics
It was the use of Argentum nit. in olden times in the treatment of epilepsy which led to the production of the lamentable cases of lead-coloured pigmentation of the skin called Argyria. Homœopathic experience has proved the applicability of the drug to many cases of epilepsy and the needlessness of employing a dosage that entails any risk whatever. The cases of epilepsy calling for this drug are those caused by fright, or occurring at the menstrual period. For days or hours before the attack the pupils are dilated, and after the attack the patient is very restless and has trembling of the hands.
