Evidence and History of Homeo-Prophylaxis

The historical evidence for the use of HP in safely and effectively preventing disease with homeopathic medicines is long and unequivocal in its support. From 1801 until the present day trials have been carried out by professional homeopaths, who until very recently were without exception also registered medical doctors. The following list in reverse chronological order catalogues many of the most significant trials and the results obtained, all of which demonstrate an ability to offer real protection against disease in above 90% of participants. In order to grasp the truly impressive nature of such figures it is important to compare it not with the antibody responses (immunogenicity) of modern vaccines which is equally high, but rather with the vaccine field trials on actual protection offered which is usually drastically lower[i] (Whooping Cough 16%, Gardasil – 14%[ii]). The overall efficacy figures where available are highlighted at the end of each abstract for ease of reference. Some may be surprised by the size, scope, length and quality of many of the trials which were often overseen by major government agencies or prominent universities.

Dr Isaac Golden and The World’s Longest HP Trials – 2004

A total of 2342 children participated for 20 years between 1985 – 2004, culminating in a PhD overseen by Epidemiologists from Melbourne’s Swinburne University. The study Concluded: HP remedies are non-toxic and safe – free of the side-effects or resulting damage that can occur with vaccines. Mild impermanent healing reactions took place in less than 2% of participants. In relation to asthma, immunizing a child with HP alone was 15 times safer than immunization by vaccines, and 6 times safer than doing nothing for immunization. In relation to eczema, immunization only with HP was 7.4 times safer than immunization with vaccines and 2.8 times safer than doing nothing about immunization. In relation to allergies, immunization only with HP was 5 times safer than by vaccines and 2 times safer than no method of immunization. The incidence of asthma (3%) in children who were immunized only by HP was well below the national average of 19%.

The incidence of behavioral problems in children immunized by HP was extremely low compared to the other methods of immunization.

Golden’s comprehensive HP program had a 90.4% efficacy against epidemic childhood diseases.

The Finlay Institutes Leptospirosis campaign in Cuba – 2007

On October November 2007, three provinces of the eastern region of Cuba were affected by strong rainfalls causing floods of big areas and several damages to sanitary and health systems. The risk of leptospirosis infection raised extremely dangerous levels with about 2 million of peoples exposed to potentially contaminated water. The Finlay Institute prepared a leptospira nosode 200 CH using 4 circulating strains and following international quality standards. A multidisciplinary team travelled to the affected regions to conduct the massive administration of the nosode. Coordinated action with public health system infrastructures allowed the administration of a preventive treatment consisting in two doses (7 9 days apart) of the nosode to about 2,4 million of people (4,8 million of doses). The coverage of the intervention rose up to 95% percent of total population of the three provinces at risk. The epidemiology surveillance after the intervention showed a dramatic decrease of morbidity two weeks after and a reduction to cero of mortality of hospitalized patient. The number of confirmed leptospirosis cases remains at low levels and bellow the expected levels according with the trends and rain regimens.

Kenyan Malarial Trial – 2003

A Malarial Trial conducted by Assie Pittendrigh in Kenya between 2003-2005 used a homeopathic Malaria Nosode in a group of 33 volunteers. Twenty-one of the participants had experienced 1 – 3 malaria episodes in the 18 months prior to the trial. During the trial, one person thought he may have developed malaria but this was not verified by blood test. After a full recovery in a matter of hours, malaria was considered unlikely. All other participants in the trial remained malaria free.

Krishnmurty’s Report on Influenzinum 1968-70

A survey conducted in Indian factories and offices compared the results of the effectiveness of Influenzinum as a homeopathic prophylactic against seasonal flu with standard allopathic measures. Almost 20 percent of the patients treated by conventional medical physicians contracted the flu. Among the homeopathically treated patients, only 6.5 percent came down with the disease. The homeopathic patients who did become ill, recovered more rapidly than their allopathically treated patients. The number of working days lost by the allopathically treated patients was nearly eight and a half times greater than those lost by homeopathic patients.

BILDET’s Hepatitis Research (1975)

Bildet investigated the protective function of Phosphorus in different potencies in the hepatic metabolism of rats submitted to induced toxic hepatitis with the administration of carbon tetrachloride and observed a positive effect.

In 1977, the same author repeated the experiment and added to it the histopathological study of the liver, confirming his previous results.

Phosphorus sur l’hépatite toxique du rat. Extracto de la tesis doctoral, Bourdeaux II, p. 2872.1975

GOMEZ (1992) repeated BILDET´s experiment confirming the protective action also observed that the high potencies as well as the ”potency chords” (several potencies simultaneously) presented greater effect than the lower potencies.

After 72 hours, the results of the transaminases were significant in all the groups studied, in relation to the control group, with the exception of the group treated with D10 (the potency used in the brazillian trials).

British Government Mustard Gas Trials – 1941-1942

During World War II the British government financed a research which was conducted separately in two different centres (London and Glasgow) using the double–blind control trial format. The study concerned volunteers who had burns from neurotoxic chemical weapons (‘mustard gases’) and who received homeopathic treatment. The treatment scheme included Mustard Gas 30CH as a prophylactic substance, and Rhus Toxicodendron 30CH and Kali Bichromicum 30CH was given as treatment. The individuals that received the homeopathic treatment presented significant improvement.

It must be mentioned that researchers also tested the effectiveness of Opium 30CH, Cantharis 30CH and Variolinum 30CH, none of which proved to be effective.

Dr Chavanon’s Historic Diptheria Trials – 1938

Chavanon administered Diphtherinum 4M and 8M and after one to two months the antitoxins were measured in the blood. He noted that a total of 45 children changed from Schick test +ve (no antibodies against diphtheria) to shick test –ve (antibodies present)

Patterson and Boyd’s Diptheria Trials – 1941

Repeated the Chavanon experiment and 20 out of 33 children were quickly observed to produce antibodies to diphtheria by Schick test. All the cases done in this way gave a Schick negative result within nine weeks, and some as early as three weeks afterwards.

Boenninghausen’s Cholera Experience – 1849

Dr Clemens von Boenninghausen treated and prevented untold numbers of cholera infections during the 1849 European epidemic with the below remedies recommended by Hahnemann. While a death rate of 54-90% occurred with conventional treatment, Boenninghausen’s patients had a mortality rate of only 5-16%

Prussian Government’s Scarlet Fever Research – 1838

Hufeland, the ‘Surgeon-General’ of Prussia at the time, reviewed all the results of the prophylactic use of Belladonna for scarlet fever. Hufeland’s support of Belladonna as a prophylactic carried so much weight that the Prussian government made its use during scarlet fever epidemics compulsary in 1838.

The above sample provides a significant body of evidence spanning more than 2 centuries, overseen by at least three major world governments and one internationally renowned university. This evidence of efficacy and safety establishes HP as a viable alternative to standard vaccination wherever it is deemed undesirable, unnecessary or impossible. With such clear international scientific and historical records claims of a lack of evidence can only be attributed ignorance, bias, or both.
