Acute tonsillitis (AT) is an upper respiratory tract infection which is prevalent, particularly in children. The cause is usually a viral or, less commonly, a bacterial infection. Treatment is symptomatic and usually consists of ample fluid intake and pain-killers; antibiotics are rarely indicated, even if the infection is bacterial by nature. The condition is self-limiting and symptoms subside normally after one week.
Homeopaths believe that their remedies are effective for AT – but is there any evidence? A recent trial seems to suggest there is.
It aimed, according to its authors, to determine the efficacy of a homeopathic complex on the symptoms of acute viral tonsillitis in African children in South Africa.
The double-blind, placebo-controlled RCT was a 6-day “pilot study” and included 30 children aged 6 to 12 years, with acute viral tonsillitis. Participants took two tablets 4 times per day. The treatment group received lactose tablets medicated with the homeopathic complex (Atropa belladonna D4, Calcarea phosphoricum D4, Hepar sulphuris D4, Kalium bichromat D4, Kalium muriaticum D4, Mercurius protoiodid D10, and Mercurius biniodid D10). The placebo consisted of the unmedicated vehicle only. The Wong-Baker FACES Pain Rating Scale was used for measuring pain intensity, and a Symptom Grading Scale assessed changes in tonsillitis signs and symptoms.
The results showed that the treatment group had a statistically significant improvement in the following symptoms compared with the placebo group: pain associated with tonsillitis, pain on swallowing, erythema and inflammation of the pharynx, and tonsil size.
The authors drew the following conclusions: the homeopathic complex used in this study exhibited significant anti-inflammatory and pain-relieving qualities in children with acute viral tonsillitis. No patients reported any adverse effects. These preliminary findings are promising; however, the sample size was small and therefore a definitive conclusion cannot be reached. A larger, more inclusive research study should be undertaken to verify the findings of this study.
Personally, I agree only with the latter part of the conclusion and very much doubt that this study was able to “determine the efficacy” of the homeopathic product used. The authors themselves call their trial a “pilot study”. Such projects are not meant to determine efficacy but are usually designed to determine the feasibility of a trial design in order to subsequently mount a definitive efficacy study.
Moreover, I have considerable doubts about the impartiality of the authors. Their affiliation is “Department of Homoeopathy, University of Johannesburg, Johannesburg, South Africa”, and their article was published in a journal known to be biased in favour of homeopathy. These circumstances in itself might not be all that important, but what makes me more than a little suspicious is this sentence from the introduction of their abstract:
“Homeopathic remedies are a useful alternative to conventional medications in acute uncomplicated upper respiratory tract infections in children, offering earlier symptom resolution, cost-effectiveness, and fewer adverse effects.”
A useful alternative to conventional medications (there are no conventional drugs) for earlier symptom resolution?
If it is true that the usefulness of homeopathic remedies has been established, why conduct the study?
If the authors were so convinced of this notion (for which there is, of course, no good evidence) how can we assume they were not biased in conducting this study?
I think that, in order to agree that a homeopathic remedy generates effects that differ from those of placebo, we need a proper (not a pilot) study, published in a journal of high standing by unbiased scientists.
