An Overview of
Positive Homeopathy Research and Surveys
The European Network of Homeopathy Researchers
November 2006
This document has been produced by the European Network for Homeopathy Researchers (ENHR).
The ENHR was established in 2004 with support from the European Council for Classical
Homeopathy (ECCH). ECCH currently assists the ENHR in its secretarial work. The ENHR consists
of 55 individuals from 14 different countries involved in or with a special interest in homeopathy
research. The ENHR is open to membership for any individual involved or interested in homeopathy
Purpose of the European Network of Homeopathy Researchers (ENHR):

The primary aim of the ENHR is to contribute to improving homeopathy research for the benefit of patients. A long-term objective of the ENHR is to contribute to carrying out international EU funded research projects within the area of homeopathy research. The ENHR consists of researchers, research advisors and representatives of the homeopathy profession as well as consumer/patient groups with an interest in the area of homeopathy research. Members of the ENHR inform each other about homeopathy research that is in the planning stages or being carried out, as well as published research articles. Introduction This document contains a sample of brief summaries of positive homeopathy research, together with the full references. Additional information may be found in the document entitled 'Facts about homeopathy and other CAM therapies’ (an ECCH document), and on the enclosed list of website addresses. Readers are recommended to read the full research articles in order to acquire a more profound knowledge base of research that has been undertaken.

A study of 1097 patients visiting 80 Norwegian homeopaths showed that one in four patients were
children between 0 and 9 years of age, compared to one in ten in 1985 and in general practice. The
most commonly presented complaints were respiratory, skin and psychological complaints.

A survey of 1400 patients treated in a homeopathic clinic showed that 36 % were under the age of 16
in 2004, compared to 26 % in 1995. Respiratory complaints, complaints of ears and skin accounted for
70 % of patients in the age group from 0 to 10 years. More than half of the patients had university or
other higher education.

A survey of more than 70 000 citizens showed that approximately 9 million people in Italy (15.6 % of
the population) have used at least one unconventional therapy in the period from 1997 to 1999.
Homeopathy was the most frequently used (8.2 % of the population). Homeopathy was also quite
commonly used by children (7.7 %). The use of CAM therapies has almost doubled since 1991.

In an observational study of 6544 consecutive patients during a 6-year period, and over 23,000
consultations, results showed that 70.7 % reported positive health changes, with 50.7 % recording their
improvement as better (+2) or much better (+3). Of the 1270 children that were treated 80.5 % had
some improvement, and 65.8 % were better (+2) or much better (+3).

In a prospective, multi-centre cohort study with 103 primary care practices treating 3981 patients,
disease severity decreased significantly (p<0.001) over a 2 year period. Major improvements were
observed for quality of life for adults and young children. 28 % (1130) of the patients were children
and 97 % of all diagnoses where chronic with an average duration of 8.8 years. The most frequent
diagnoses were allergic rhinitis in men, headache in women, and atopic dermatitis in children.

An Overview of Positive Homeopathy Research and Surveys, ENHR, November 2006 REVIEWS AND META-ANALYSES

A meta-analysis is a means of combining results from more than one trial to look for overall trends.
(NB! In general complicated research terminology such as OR, CI, and words such as significant or
randomized should only be used in communications with people who will understand such
terminology. Otherwise stick to what can be understood by all, e.g. a survey of all the high quality
research that has been carried out clearly shows that homeopathy is effective.)
Results were found in favour of homeopathy in 20 of 22 systematic reviews on the effect of
homeopathic high-potencies on cells or living organisms. For upper respiratory tract infections and
allergies six out of seven studies were in favour of homeopathy. The authors of this article concluded
that the effectiveness of homeopathy can be supported by clinical evidence and treatment is safe. The
article has been published by authors who took part of the Program for Evaluation of Complementary
Medicine (PEK), the same program which in August 2005 resulted in the publication of an article by
Shang et al, where the conclusion was that the effect of homeopathy is placebo.

In a review of homeopathy research the authors found three independent systematic reviews of
placebo-controlled trials on homeopathy that reported effects that seem to be more than placebo, and
one review that found its effects consistent with placebo.

A systematic review and meta-analysis showed highly significant results for surveys adding up to a
total of 2 617 patients (P=0.000036). Results were not that significant for high quality surveys
(P=0.08). The author concludes that further high quality studies are needed to confirm results.

A systematic review of results from 93 substantive RCTs was carried out by Robert Mathie (2003). It
concludes that of the 35 different medical conditions covered by these trials the weight of evidence

Meta-analysis of 89 trials of homeopathic medicine versus placebo. Result: significantly in favour of
homeopathy (OR 2,45 (95% CI 2,05-2,93)). This meta-analysis included 186 placebo-controlled
studies of homeopathy published until mid-1996, of which data for analysis could be extracted from
89. The overall odds ratio was 2.45 (95% confidence intervals 2.05-2.93) in favour of homeopathy,
which means that the chances that homeopathy would benefit the patient were 2.45 times greater than
placebo. When considering just those trials of high quality published in MEDLINE listed journals, and
with predefined primary outcome measures, the pooled odds ratio was 1.97 and significant. Even after
correction for publication bias the results remained significant. The main conclusion was that the
results "were not compatible with the hypothesis that the effects of homeopathy are completely due to
placebo". If the result of new trials were to show no difference between homeopathy and placebo, we
would have to add 923 trials with no effect with 118 patients in each in order to balance the two.

HMRG report with overview of clinical research in homeopathy, identified 184 controlled clinical
trials. They selected the highest quality randomized control trials, which included a total of 2617
patients for a meta-analysis. This meta-analysis resulted in a p-value of 0.000036 (which means that
results are highly significant) indicating that homeopathy is more effective than placebo. The
researchers concluded that the "hypothesis that homeopathy has no effect can be rejected with
certainty". Homeopathic Medicine Research Group.

Of the 105 trials with interpretable results, 81 trials indicated positive results. Most studies showed
results in favour of homeopathy even among those randomized controlled trials that received high-
quality ratings for randomization, blinding, sample size, and other methodological criteria. They came
to the following conclusion: "The amount of positive evidence even among the best studies came as a
surprise to us. Based on this evidence we would readily accept that homeopathy can be efficacious, if
only the mechanism of action were more plausible. The evidence presented in this review would
probably be sufficient for establishing homeopathy as a regular treatment for certain indications".

Respiratory tract complaints

Homeopathy versus conventional treatment in respiratory tract complaints
In an outcome study, 30 practitioners in four countries enrolled 500 consecutive patients with at least
one of three complaints: upper respiratory tract complaints including allergies; lower respiratory tract
complaints including allergies; or ear complaints. Of 456 patients, 281 received homeopathy and 175
conventional treatment. The primary outcome criterion was response to treatment, defined as cured or
major improvement after 14 days of treatment. Results showed a response rate of 82.6% in the
homeopathy group compared to 67.3% in the group receiving conventional medicine. The authors
concluded that homeopathy appeared to be at least as effective as conventional treatment of patients
with the three conditions studied.

Homeopathy versus conventional treatment in recurrent acute rhinopharyngitis in children
Prospective pragmatic study, comparison of homeopathy versus antibiotics in the treatment of
recurrent acute rhinopharyngitis in children (18 months to 4 years) over a 6 month period. Results
showed that homeopathy was significantly better than antibiotics in terms of episodes of
rhinopharyngitis (2.71 vs 3.97, p<0.001), number of complications (1.25 vs 1.95, p<0.001) and quality
of life (global score: 21.38 vs 30.43, p<0.001). Homeopathic treatment also contributed to lower
medical costs (88 Euros vs 99 Euros, p<0.05) and significantly less sick-leave (9.5% of parents vs
31.6% of parents, p<0.001).

Respiratory tract complaints

Homeopathy versus conventional treatment in otitis media
Prospective observational study, comparison of homeopathy versus conventional treatment in acute
otitis media. Conclusion: homeopathy should be first line treatment in acute otitis media. Results
showed median duration of pain of 2 days in the homeopathy-group and 3 days in the conventional
medicine group. 70.7 % of the children receiving homeopathic treatment did not have another ear
infection the next year and 29.3 % had a maximum of three ear infections within one year. 56.5 % in
the conventional medicine group did not have another ear infection the next year and 43.5 % had a
maximum of six ear infections the next year. Results showed that in the group receiving homeopathic
treatment only 5 out of 103 children needed antibiotics.

Acute otitis media in children
A study involving children suffering from acute otitis media suggests that a positive treatment effect
from homeopathy when compared with placebo in acute otitis media cannot be excluded. There were
fewer treatment failures in the group receiving homeopathy after 5 days, 2 weeks, and 6 weeks, with
differences of 11.4, 18.4, and 19.9%, respectively, but these differences were not statistically
significant. Diary scores showed a significant decrease in symptoms at 24 and 64 h after treatment in
favour of homeopathy (P<0.05).

Acute otitis media in children
In a trial of 230 children who were given homeopathic treatment to treat acute otitis media, pain relief
was achieved in 39% of the patients after 6 h and another 33% after 12 h. The resolution rates were 2.4
times faster than in placebo controls. No complications were observed and compared to conventional
treatment the homeopathic approach was 14% cheaper.

Glue ear in children
In a pilot study in children suffering from glue ear treated with homeopathy 75% had normal
tympanogram, compared to 31% in the group treated with conventional medicine. A higher proportion
of children receiving homeopathic treatment had a hearing loss less than 20 dB at follow-up, though
the difference was not statistically significant. The authors concluded that further research comparing
homeopathy to standard care is warranted; 270 patients would be needed for a definitive trial.

Acute sinusitis
In an uncontrolled clinical trial of 119 patients suffering from clinical signs of acute sinusitis were
treated using homeopathic medicines. Typical sinusitis symptoms, such as headache, pressure pain at
nerve exit points, and irritating cough, were reduced after a mean of 4.1 days of treatment. Ninety-nine
received only a homeopathic test medication, 20 patients were able to discontinue concomitant
medication at the first visit, and only one patient needed antibiotics. Average duration of treatment
was 2 weeks. At the end of treatment 81.5 % described themselves as symptom free or significantly
improved. No adverse medication effects were reported.

Rheumatoid arthritis
Forty-six patients with rheumatoid arthritis received an individualised remedy or placebo in a 3-month
randomised trial. Both groups were allowed to continue standard anti-inflammatory drugs. After 3
months, the double-blind code was broken and remedies were given to members of the placebo group
in a single crossover study. Articular index, limbering up time, grip strength and pain all showed
statistically significant differences.

In this trial, 65 sufferers of Osteoarthritis (OA) were split into 2 groups, and through a double blinding
process were given either a homoeopathic medicine or Acetaminophen, a commonly prescribed drug
for pain relief in OA. Researchers found that homoeopathy provided a level of pain relief that was
superior to Acetaminophen, and produced no adverse reactions.

Hay fever, asthma and perennial rhinitis

A study of 200 patients suffering from hypersensitivity illnesses, including asthma, eczema, urticaria,
hay fever and other allergies, showed that homeopathy was at least as effective as conventional
treatment. The study, which was retrospective and comparative, looked at the experienced effect in
everyday clinical practice of general practitioners and classical homeopaths. Where most patients who
were treated by medical doctors experienced an aggravation of their symptoms when stopping
conventional drugs, only 1/3 of patients in the homeopathy group experienced such an aggravation (P
= 0.002). Only one patient on conventional treatment experienced improvement of symptoms after
stopping medication, compared to improvement in 2/3 of homeopathy patients. Patients in the
homeopathy group reported a larger improvement in their general state of health, with 57% improving,
compared to 24% in the conventional group (difference P = 0.004). Homeopathy patients also
experienced more positive change in their psychological state (P<0.0001). For quality of life 53% in
the homeopathy group improved, compared to 15 % in the conventional group.

Reilly and colleagues have conducted a series of trials in patients with hay fever, asthma and perennial
rhinitis. Patients were given skin tests and remedies were chosen on the basis of reactivity. This design
allows individualisation whilst avoiding the issues of case-taking and the effect that this has on the
process. The results demonstrate a significant difference between the placebo and homeopathic groups
which is reproducible. (NB! Strictly speaking these are trials of isopathy.)

Pre menstrual syndrome (PMS)

In a randomized controlled double-blind clinical trial (1992-94) 19 women suffering from PMS were
treated individually with homeopathy. 90 % of the patients who had received homeopathic treatment
experienced more than 30 % improvement. Only 37.5 % of patients who received placebo experienced a
similar improvement. Sick-days before menses were reduced from 0.75 to 0 in the homeopathy-group,
and was unchanged in the control group. Use of conventional drugs was also reduced in the homeopathy-

Homeopathy in menopausal complaints

In a prospective study 81.4% of 102 patients reported improvement of menopause symptoms after
homeopathic treatment. Main symptoms noted were hot flushes and sweats, tiredness, anxiety,
sleeping difficulties, mood swings and headaches. Women referred to homeopathy were those who
either could not take hormone replacement treatment (HRT), for whom HRT was unsuccessful, who
did not want or who had to come off HRT. Mean length of homeopathic treatment was 5 months.

An outcome study and service evaluation of homeopathy service found that 88% of patients reported
clinically significant improvement in their primary symptom. Greatest clinical benefit was reported by
women for headaches, tiredness, vasomotor symptoms, locomotor symptoms and sleeping difficulties.

Homeopathy and oestrogen withdrawal

40 out of 45 women with breast cancer withdrawing from oestrogen and then treated homeopathically,
experienced significant improvement in their primary symptoms, anxiety and depression, as well as
improvement in quality of life. Primary symptoms changed from 7.8 to 5.4, and from 7.2 to 4.1
(p<0.001). The homeopathic approach appears to be clinically useful in the management of oestrogen
withdrawal symptoms in women with breast cancer.

A randomised double blind placebo controlled crossover trial of 62 children showed significant
improvement of visual global perception, impulsivity and divided attention (p<0.0001). The trial
suggests scientific evidence of the effectiveness of homeopathy in the treatment of ADHD,
particularly in the areas of behavioural and cognitive functions.

In a trial to assess the efficacy of homeopathy in 115 hyperactive patients (mean age 8.3 years, range
3-17 y) compared to methylphenidate 75% of the children responded to homeopathy, reaching a
clinical improvement rating of 73%. Children who did not respond to homeopathic treatment were
prescribed methylphenidate (after an average period of 22 months of homeopathic treatment).

A randomised double-blind trial involving 62 patients with ME, reported in some detail, found that
33% of patients in the group receiving homeopathic remedies showed definite improvement compared
with none in the placebo group.

In a comparative cohort study of 493 patients with chronic diagnoses results indicated greater
improvement in patients’ assessments after homeopathic versus conventional treatment (adults:
homeopathy from 5.7 to 3.2; conventional 5.9 to 4.4, p = 0.002; children: from 5.1 to 2.6, and 3.9 to
2.7, p < 0.001). Physician assessments were also more favourable for children who had received
homeopathic treatment. There were no significant differences in costs between the two treatment

homoeopathic and conventional treatment strategies: A comparative cohort study in patients with
chronic disorders. Complementary Therapies in Medicine (2005) 13, 79-86.

A 4-year study of 84 patients treated homeopathically showed average cost savings for drugs per
patient of £60.40 (range £12.48 to £703.95). 64 patients were cured, 16 showed significant
improvement, 5 moderate improvement affecting daily living, 5 showed no change or were unsure,
and 10 are still under treatment. No side-effects of treatment were reported.

prescribing costs in General Practice. Homeopathy (2003) 92, 71-76.

In a survey of 223 patients in an NHS General Practice, the number of consultations with general
practitioners was reduced by 70% in a 1 year period. Expenses for medication were reduced by 50%
when homeopathic treatment was made available.

In a study of 351 adults suffering from allergies, 35.3% received homeopathic treatment, the
researchers concluded that alternative medicine is used widely for allergies by the general population
and is associated with considerable costs. This has freedom of choice and cost-benefit implications for
the healthcare system and health policy. The study also showed that alternative medicine users were
better educated than non-users, and assessed the results of alternative medicine as very good (28.6%)
or rather good (53.8%).

use, and costs. Allergy 2002; 57: 694–700.

A study of the cost and effectiveness of homeopathy suggested that doctors practising homeopathy
issue fewer prescriptions and at a lower cost than their colleagues. The main costs for homeopathic
treatment are for consultations with each individual patient. Costs for the actual medications used are
relatively low, particularly when compared with conventional drugs.

The effect of high dilutions

In an experimental study of ultra-high dilutions of litihum chloride and sodium chloride, researchers
found emission of light even in dilutions beyond Avogadro’s number (10-30 g cm-3). The solutions
were irradiated by x- and gamma-rays at 77 K, then progressively rewarmed to room temperature.
Thermoluminescence was studied during the process.
Rey L. Thermoluminescence ofultra-high dilutions of lithium chloride and sodium chloride. Physica A
323 (2003) 67–74.

In an experimental study of extremely diluted and succussed solutions (< 1x10-5 mol kg-1, chemically
identical to distilled water) researchers found that the diluted and succussed solution resulted in
exothermic excess of heat (heat resulting from chemical reactions), higher electrical conductivity and
pH compared to an untreated substance. The authors conclude that they show that successive dilutions
and succussions can permanently alter the physico-chemical properties of the water solvent. The
authors are unable to explain the phenomena.

Thermal Analysis and Calorimetry, Vol. 75 (2004) 815–836.

In a multi-centre study including four research centres in Europe the effect of high dilutions of
histamine (10-30 – 10-38 M) were confirmed. Researchers were able to document that high dilutions of
histamine inhibit human basophil degranulation. Results cannot be explained through molecular

dilutions modulate basophil activation. Inflamm. Res. 2004; 53: 181-188.

The effect of high dilutions was documented in an experiment showing the effect of highly diluted
Belladonna on acetylcholine-induced contraction of the rat ileum. The model is reproducible and
highly recognised in ‘the scientific world’.

A placebo-controlled homeopathic pathogenic trial, more commonly known as a proving, clearly
demonstrated that provers who took the substances in C30 potency experienced significantly more
symptoms than a placebo group (P<0.001). Provers were given either Etna Lava C30, Hydrogenium
peroxidatum C30, or placebo. Where the placebo group experienced some symptoms, they were more
short-lived compared to the verum group which experienced persistent symptoms for the first 30 days.
Provers in the verum group also experienced more ‘old symptoms’ returning. A weakness of the
survey is that it only included 21 provers. Researchers have now called for more data from more

In an experimental study on the effect of histamine on basophile granulocytes, researchers found an
effect of histamine diluted beyond Avogadro’s number.

An Overview of Positive Homeopathy Research and Surveys, ENHR, November 2006 Treatment of animals

In a blinded study where rats were treated for urinary infections results showed that rats treated with
homeopathic remedies had clear reduction of bacterial colonies. Results were at least as clear as for
treatment with antibiotics. Untreated rats had no changes in bacteria colonies, compared to a reduction
to 33 % of original bacteria levels in rats treated with antibiotics, and 22 % and 39 % in rats treated
with homeopathic remedies (Phosphorus and self-nosode).
