Characteristics.-Sulphuric acid and Sulphur are themselves in the first rank of periodic remedies, and combined with the chief alkaloid of China they enhance the powerful periodic properties of that drug. In old-school practice the Sulphate of Quinine has almost entirely taken the place of the crude Bark as a remedy. Chin. sul. closely resembles China in its effects, but as it has been proved separately, and as observations of the effects of over-dosing have supplied many additional symptoms, the homoeopathist has plenty of guidance in the selection of one in preference to the other. Chi. sul. is even more powerful as an antiseptic than China, and it is probable that it is in virtue of its property of antagonising the malarial poison that it suppresses intermittent fever when it does not cure. It only cures when the fever corresponds to its own type. When a fever is “suppressed” there is generally air unholy alliance between disease-force and drug-force, which is expended on some part of the organism, resulting at times in lifelong ill-health. The “Quinine cachexia” is well known-sallow complexion, emaciation, deafness and singing in the ears, enlarged spleen, disposition to shiver, and great debility. Periodicity is extremely well marked, the attacks returning at the same hour each day. In intermittents the onset may anticipate. Skin flaccid and sensitive to touch. Red rash over whole body, with severe stinging, followed by desquamation. Other prominent symptoms are: Headache extending from occiput to forehead. Whirling in the head like a mill-wheel. Twitching of left eyelid, < in the evening. Aphthae in weakly people. Tartar on teeth. Hunger at night. Prolapse of rectum, especially in children. Haematuria and haemoglobinuria. (“Black-water fever” has been developed through administering Chi. sul. in intermittents. Koch deserves much credit for showing that the worst features of African fevers are due to over-dosing with Quinine and not to the disease). E W. Sawyer (Med. Advance, 1887) relates this instructive history: He learned from his cook that her brother (aet. 16) could not take a particle of Quinine without causing a profuse flow of blood with the urine, sometimes within half an hour, always without pain. This had followed every time his doctors had tried to “break his ague” with Quinine. A year later a farmer’s wife, aet. 60, came to Dr. Sawyer to be treated for bloody urine unattended with pain or uneasiness. She attributed it to strain from walking two miles on a slippery road. She had been for months under Hygienist treatment without benefit, and was alarmingly weak from loss of blood. Rhus 200, Ham. 1x, Erig. 1x, Chi. 1x, Fer. mur. 2x were given in succession in vain. At last, calling to mind the case of the youth, he gave Chi. sul. in 1 / 16 gr. doses three times a day, and a prompt cure was effected. Chi. sul. causes painfulness and swelling of varicose veins during a chill. (Julius E. Schmitt cured a case on this last indication.) Great sensitiveness to external influences. All discharges debilitating. Weak and nervous; a little exercise = sweat from least exertion. Head gradually breaks into sweat when perfectly quiet. Chi. sul. is one of the medicines which have the “sinking sensation.” Tyrrell had a patient in whom in any potency it caused her to become “deathly sick and faint, thought she would die, could not raise her head, felt she would sink through the bed.” Sacch. alb. produced in her the same symptoms, and she accused the doctor of having given her Quinine. (Arsen. has “sinking sensation,” “as if bed had gone from under her and she had alighted on the floor.” Bell., Dulc., Rhus, Lach., have “sinking through the bed.”) Palpitation. Touch . Wants to lie down. Motion = chilliness. Stooping = giddiness. Bending forward >. Sleeplessness and over-stimulation of nervous system.

Relations.-See China. It is antidoted by: Arn., Ars., Carb. v., Ferrum, Hep., Lach., and especially Nat. mur., which antidotes effects of over-dosing with Quinine; Puls. Compare: Cinchon sul., Apis. (chill 3 p.m.); Ars. (pyaemia, spinal irritation, periodically returning neuralgias); Bry. (sweat from least exertion); Carb. an. (all discharges debilitating); Eup. perf. (sweat relieves all symptoms but headache); Nux (blue lips and nails with chill); Puls. (rheumatic erratic pains); Stann. (supra-orbital neuralgia); Staph. (head gradually breaks into sweat while perfectly quiet). In headache from before backward (Gels., Lac. c., Sang., Sil.).

“Materia Medica” is a term commonly used in the field of homeopathy to refer to a comprehensive collection of information on the characteristics and therapeutic uses of various natural substances, including plants, minerals, and animal products.

One such work is “Materia Medica,” a book written by Benoit Mure, a French homeopath, in the 19th century. The book is considered a valuable resource for homeopaths and is still widely used today.

In “Materia Medica,” Mure provides detailed information on over 100 homeopathic remedies, including their sources, preparation methods, physical and mental symptoms, and indications for use. He also discusses the philosophy and principles of homeopathy, as well as its history and development.

The book is known for its clear and concise writing style, and it has been praised for its accuracy and depth of knowledge. It remains a popular reference for homeopaths and students of homeopathy.

Overall, “Materia Medica” by Benoit Mure is an important work in the field of homeopathy and is highly recommended for anyone interested in learning about the use of natural remedies in the treatment of various health conditions.

Homoeopathy is a system of alternative medicine that is based on the concept of “like cures like.” It uses highly diluted substances that are believed to cause similar symptoms as the illness being treated.

There are many online homoeopathic Materia medica, which are resources that list and describe the properties and uses of different homoeopathic remedies. Some popular online homoeopathic Materia medica include:

Boericke’s Materia Medica: A comprehensive reference guide to homoeopathic remedies, including information on their uses, indications, and dosages.

Clarke’s Dictionary of Homeopathic Materia Medica: A well-respected and widely used reference that includes information on the symptoms that each remedy is used to treat.

Homeopathic Materia Medica by William Boer Icke: A popular homoeopathic reference book that provides in-depth information on a wide range of remedies, including their indications, symptoms, and uses.

The Complete Repertory by Roger van Zandvoort: A comprehensive online reference that provides information on remedies, symptoms, and indications, and allows users to search for treatments based on specific symptoms.

There are many writers who have contributed to the development of homoeopathic materia medica. Some of the most well-known include:

Samuel Hahnemann: The founder of homoeopathy, Hahnemann wrote extensively about the use of highly diluted substances in treating illness. He is best known for his work “Organon of the Medical Art,” which outlines the principles of homoeopathy.

James Tyler Kent: Kent was an American homoeopathic physician who is known for his contributions to homoeopathic materia medica. He wrote “Repertory of the Homeopathic Materia Medica,” which is still widely used today.

William Boericke: Boericke was an Austrian-American homoeopathic physician who wrote the “Pocket Manual of Homeopathic Materia Medica.” This book is considered one of the most comprehensive and widely used homoeopathic reference books.

George Vithoulkas: Vithoulkas is a Greek homoeopathic physician and teacher who has written several books on homoeopathic materia medica, including “The Science of Homeopathy” and “Essence of Materia Medica.”

Robin Murphy: Murphy is an American homoeopathic physician who has written several books on homoeopathic materia medica, including “Homeopathic Clinical Repertory” and “Homeopathic Medical Repertory.”
