Amylenum Nitrosum

Symptoms of the homeopathic remedy Amylenum Nitrosum from the Guiding Symptoms of our Materia Medica by Constantine Hering, a ten volumes comprehensive record of confirmed symptoms, published in 1879….

     Nitrite of Amyl. C10 H11 O, NO3.

     Discovered by Ballard in 1884, proposed as a medicine by Guthrie in 1859, introduced into the Materia Medica of Old School in 1866. Introduced into our School in 1871. Proved by T. F. Allen and published in his Encyclopedia in 1874. Again proved by the Boston School and published by C. Wesselhoeft in 1876, a first-rate proving, which could not be dispensed with. There are very few cures on record, mostly palliations of incurable cases ; but it is of the utmost importance as regards euthanasia. Before going to press we received an excellent collection, through J. H. McClelland, by S. B. Chanter.

C. Hering
Hering got the degree of M. D. from the University of Wuezburg with highest honours. The theme of his thesis was "De'Medicina Futura" (The medicine of future). Hering left Germany for West Indies and finally arrived at Philadelphia in Jan, 1833. He established a homeopathic school at Allentown, Pennsylvania, commonly known as "Allentown Academy". Soon he became very popular as a physician. He is known as the 'Father of Homeopathy' in America.
