  • In Memoriam, Dr. Peter Fisher

    by Jennifer Jacobs

    Our community has suffered an irreplaceable loss—that of Dr. Peter Fisher, a shining beacon of light for homeopathy. Peter was, without a doubt, the most articulate, knowledgeable, and passionate proponent of homeopathy in the entire world. He was also kind, patient, and generous with his time, always willing to attend conferences, speak at government hearings, or co-author an article. He was the go-to person for anyone needing a calm, sensible voice to defend homeopathy against increasingly scurrilous claims. I knew Peter for more than 30 years as a friend and colleague, and visited his home on several occasions. I sometimes worried that he worked too hard, with all of his responsibilities at the Royal London Homeopathic Hospital, as editor of the journal Homeopathy, as a researcher, and as a clinician. But he did take time out to enjoy gardening, cooking, and vacationing with his family. It is hard to believe that he is gone, and that we will never again experience his brilliant mind or his droll, biting, wit. Although no-one can ever fill his shoes, we must all dedicate ourselves to moving homeopathy forward and keeping his legacy alive.

  • Homeopathic Prevention and Management of Epidemic Diseases

    by Jennifer Jacobs

    Background Homeopathy has been used to treat epidemic diseases since the time of Hahnemann, who used Belladonna to treat scarlet fever. Since then, several approaches using homeopathy for epidemic diseases have been proposed, including individualization, combination remedies, genus epidemicus, and isopathy. Methods The homeopathic research literature was searched to find examples of each of these approaches and to evaluate which were effective. Results There is good experimental evidence for each of these approaches. While individualization is the gold standard, it is impractical to use on a widespread basis. Combination remedies can be effective but must be based on the symptoms of a given epidemic in a specific location. Treatment with genus epidemicus can also be successful if based on data from many practitioners. Finally, isopathy shows promise and might be more readily accepted by mainstream medicine due to its similarity to vaccination. Conclusion Several different homeopathic methods can be used to treat epidemic diseases. The challenge for the future is to refine these approaches and to build on the knowledge base with additional rigorous trials. If and when conventional medicine runs out of options for treating epidemic diseases, homeopathy could be seen as an attractive alternative, but only if there is viable experimental evidence of its success.


  • Systematic review and meta-analysis of randomised, placebo-controlled, trials of individualised homeopathic treatment

    by Robert T. Mathie, Michel Van Wassenhoven, Jennifer Jacobs, Menachem Oberbaum, Joyce Frye, Raj K. Manchanda, Helmut Roniger, Flávio Dantas, Lynn A. Legg, Jürgen Clausen, et al.

    Background: The BHA's programme of systematic reviews of randomised controlled trials (RCTs) of homeopathy distinguishes key attributes of study design and intervention: placebo controlled cf. other-than-placebo controlled; individualised cf. non-individualised homeopathy; treatment cf. prophylaxis.

  • Model validity of randomised placebo-controlled trials of individualised homeopathic treatment

    by Robert T Mathie, Michel Van Wassenhoven, Jennifer Jacobs, Menachem Oberbaum, Helmut Roniger, Joyce Frye, Raj K Manchanda, Laurence Terzan, Gilles Chaufferin, Flávio Dantas, et al.

    Background: Though potentially an important limitation in the literature of randomised controlled trials (RCTs) of homeopathy, the model validity of homeopathic treatment (MVHT) has not previously been systematically investigated.Objective: As an integral part of a programme of systematic reviews, to assess MVHT of eligible RCTs of individualised homeopathic treatment.Methods: From 46 previously identified papers in the category, 31 papers (reporting a total of 32 RCTs) were eligible for systematic review and were thus the subject of the study. For each of six domains of assessment per trial, MVHT was judged independently by three randomly allocated assessors from our group, who reached a final verdict by consensus discussion as necessary.Results: Nineteen trials were judged overall as ‘acceptable’ MVHT, nine as ‘uncertain’ MVHT, and four as ‘inadequate’ MVHT.Conclusions: These results do not support concern that deficient MVHT has frequently undermined the published findings of RCTs of individualised homeopathy. However, the 13 trials with ‘uncertain’ or ‘inadequate’ MVHT will be a focus of attention in supplementary meta-analysis. New RCTs of individualised homeopathy must aim to maximise MVHT and to enable its assessment through clear reporting.

    Method for appraising model validity of randomised controlled trials of homeopathic treatment: multi-rater concordance study

    by Robert T Mathie, Helmut Roniger, Michel Van Wassenhoven, Joyce Frye, Jennifer Jacobs, Menachem Oberbaum, Marie-France Bordet, Chaturbhuja Nayak, Gilles Chaufferin, John A Ives, et al.

    A method for assessing the model validity of randomised controlled trials of homeopathy is needed. To date, only conventional standards for assessing intrinsic bias (internal validity) of trials have been invoked, with little recognition of the special characteristics of homeopathy. We aimed to identify relevant judgmental domains to use in assessing the model validity of homeopathic treatment (MVHT). We define MVHT as the extent to which a homeopathic intervention and the main measure of its outcome, as implemented in a randomised controlled trial (RCT), reflect 'state-of-the-art' homeopathic practice.


  • Homeopathy for Menopausal Symptoms in Breast Cancer Survivors: A Preliminary Randomized Controlled Trial

    by Jennifer Jacobs, Patricia Herman, Krista Heron, Steven Olsen, Lucy Vaughters

    Objectives: To carry out a preliminary trial evaluating the effectiveness of two types of homeopathy for the treatment of menopausal symptoms in breast cancer survivors. Design: Randomized, double-blinded, placebo-controlled Settings/location: Private medical clinic, Seattle, WA. Subjects: Women with a history of breast cancer who had completed all surgery, chemotherapy, and radiation treatment and who had an average of at least three hot flashes per day for the previous month. Interventions: Subjects were randomized to receive either an individualized homeopathic single remedy, a homeopathic combination medicine, or placebo. Patients were seen by homeopathic providers every 2 months for 1 year. Outcome measures: Hot flash frequency and severity, Kupperman Menopausal Index (KMI), Short Form 36 (SF-36). Results: There was no significant difference found in the primary outcome measure, the hot flash severity score, although there was a positive trend in the single remedy group during the first 3 months of the study (p = 0.1). A statistically significant improvement in general health score in both homeopathy groups (p < 0.05) on the SF-36 after 1 year was found. Evidence of a homeopathic "drug proving" in the subjects receiving the homeopathic combination medicine who were not taking tamoxifen also was found. Conclusions: Small sample size precludes definitive answers, but results from this preliminary trial suggest that homeopathy may be of value in the treatment of menopausal symptoms and improving quality of life, especially in those women not on tamoxifen. Larger studies should be carried out that also include healthy women who want to avoid hormone replacement therapy.


  • Homeopathy for childhood diarrhea: combined results and metaanalysis from three randomized, controlled clinical trials

    by Jennifer Jacobs, Wayne B. Jonas, Margarita Jiménez-Pérez, Dean Crothers

    Previous studies have shown a positive treatment effect of individualized homeopathic treatment for acute childhood diarrhea, but sample sizes were small and results were just at or near the level of statistical significance. Because all three studies followed the same basic study design, the combined data from these three studies were analyzed to obtain greater statistical power. Three double blind clinical trials of diarrhea in 242 children ages 6 months to 5 years were analyzed as 1 group. Children were randomized to receive either an individualized homeopathic medicine or placebo to be taken as a single dose after each unformed stool for 5 days. Parents recorded daily stools on diary cards, and health workers made home visits daily to monitor children. The duration of diarrhea was defined as the time until there were less than 3 unformed stools per day for 2 consecutive days. A metaanalysis of the effect-size difference of the three studies was also conducted. Combined analysis shows a duration of diarrhea of 3.3 days in the homeopathy group compared with 4.1 in the placebo group (P = 0.008). The metaanalysis shows a consistent effect-size difference of approximately 0.66 day (P = 0.008). The results from these studies confirm that individualized homeopathic treatment decreases the duration of acute childhood diarrhea and suggest that larger sample sizes be used in future homeopathic research to ensure adequate statistical power. Homeopathy should be considered for use as an adjunct to oral rehydration for this illness.


  • Homeopathic treatment of acute otitis media in children: a preliminary randomized placebo-controlled trial

    by Jennifer Jacobs, David A. Springer, Dean Crothers

    The use of antibiotics in the initial treatment of acute otitis media is currently being questioned. Homeopathy has been used historically to treat this illness, but there have been no methodologically rigorous trials to determine whether there is a positive treatment effect. A randomized double blind placebo control pilot study was conducted in a private pediatric practice in Seattle, WA. Seventy-five children ages 18 months to 6 years with middle ear effusion and ear pain and/or fever for no more than 36 h were entered into the study. Children received either an individualized homeopathic medicine or a placebo administered orally three times daily for 5 days, or until symptoms subsided, whichever occurred first. Outcome measures included the number of treatment failures after 5 days, 2 weeks and 6 weeks. Diary symptom scores during the first 3 days and middle ear effusion at 2 and 6 weeks after treatment were also evaluated. 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 favor of homeopathy (P < 0.05). Sample size calculations indicate that 243 children in each of 2 groups would be needed for significant results, based on 5-day failure rates. These results suggest that a positive treatment effect of homeopathy when compared with placebo in acute otitis media cannot be excluded and that a larger study is justified.
