Abstract:Even though homeopathy is regarded as a harmless intervention, homeopathic practice may not be entirely risk-free. Risk in homeopathy can be divided into direct and indirect risk. Direct risk refers to traditional adverse effects of an intervention; indirect risk is related to adverse effects in a treatment context, e.g. the practitioner. Available data suggest that the risk profile of homeopathic remedies in ultra-molecular potencies is minor, but there is a potential for indirect risk related to homeopathic … Show more
“…The doctors' perceptions are examples of 'objective', scientific risk knowledge concerning direct risks, i.e. risk caused by the treatment itself and related directly to the intervention [44]. The encounter between patients' and doctors' risk perceptions can be perceived as 'risk as politics', involving power structures and knowledge systems within modern risk societies [45].…”

Background: Studies on the widespread use of complementary and alternative medicine (CAM) demonstrate that CAM users base their treatment decisions on both subjective, experience-based knowledge and medical knowledge. The aim of this study was to explore lay and medical risk perceptions associated with CAM and conventional medicine. Patients and Methods: In this explorative qualitative study, we conducted in-depth interviews with 25 Norwegian CAM users with cancer or multiple sclerosis and 12 doctors. Results: The interviews revealed fundamental differences in risk perceptions influencing treatment decisions and risk communication in a clinical setting. While CAM users considered conventional medicine as potentially risky and related this to experiences of severe adverse effects, CAM was perceived as natural and safe. Doctors' risk perceptions were quite the contrary, mainly because of lack of scientific evidence for CAM as a safe and beneficial treatment option. Conclusion: For the safety of CAM users, such divergent risk perceptions may have far-reaching consequences. CAM users should be taken seriously with their self-perception as decision-makers considering their approaches to experiences, knowledge, and science. An awareness of differing lay and medical risk perceptions associated with CAM and conventional medicine in research, doctor-patient communication, and education of patients and doctors is thus important to optimize patient safety in complex health care systems.

“…Nonetheless, homeopathic treatment with ultra-molecular remedies has been proven to be clinically effective, but the mechanisms of effect remain unclear and under discussion. It has been speculated, that psychological mechanisms such as the placebo effect, potentially play a role (32) As a consequence of this complex situation, a rather broad definition of risk, including both direct and indirect risk, maybe most appropriate in order to map the potential harm to patients related to the homeopathic treatment situation (33). This definition should encompass all potentially unwanted effects, without making assumptions about their mechanisms.…”

Highlights:• This review address the naive assumption that because of the generally diluted doses used homeopathy must be safe• This review touches the neglected issue of the distinction between homeopathic aggravation, adverse reactions and adverse effects• We found a similar risk for homeopathic treatment compared to controls such as placebo and conventional medicine.

Abstract ObjectivesHomeopathy is a popular treatment modality among patient, however there is sparse research about adverse effects of homeopathy. A concept unique for homeopathy, is homeopathic aggravation that is understood as a transient worsening of the patients' symptoms before an 2 expected improvement occurs. From a risk perspective it is vital that a distinction between homeopathic aggravations and adverse effects is established. There is a lack of systematic information on how frequent adverse effects and homeopathic aggravations are reported in studies. Therefore, a systematic review and meta-analysis were performed.
Design and settingSixteen electronic databases were searched for Randomized Controlled Trials (RCTs). The searches were limited from the year 1995 to January 2011. Forty-one RCTs, with a total of 6.055 participants were included. A subtotal of 39 studies was included in the additional metaanalysis.
ResultsA total of 28 trials (68%) reported adverse effects and five trials (12%) reported homeopathic aggravations. The meta-analysis (including six subgroup comparisons) demonstrated that no significant difference was found between homeopathy and control with OR 0.99, 95% CI 0.86 to 1.14, I 2 = 54%. More than two third of the adverse effects were classified as grade 1 (68%) and two third were classified as grade 2 (25%) and grade 3 (6%) according to the Common Terminology Criteria for Adverse Effects. Homeopathic aggravation was classified as grade 1 (98%) and grade 3 (2%), suggesting that homeopathic aggravations were reported to be less severe than adverse effects. The methodological quality according to a method recommended in the Cochrane handbook for RCTs, was high.
ConclusionAdverse effects including the concept of homeopathic aggravations are commonly reported in trials. The meta-analysis demonstrated that the proportion of patients experiencing adverse effects to be similar for patients randomized to homeopathic treatment compared to patients randomized to placebo and conventional medicine.
“…Und nicht zu vergessen: Homöopathie ist pragmatisch hilfreich [24,25,26,27]. Zwar kommt es bei homöopathischer Behandlung gelegentlich zu einer Erstverschlimmerung [28,29], aber die Behauptung, Homöopathie sei gefährlich [30], ist eine fahrlässige Interpretation der Daten [31]. …”
