Tinnitus is a prevalent condition which has no practical and effective pharmacological treatment. In the absence of relief by conventional routes, sufferers are increasingly turning to 'alternative' or 'complementary' medicine. This paper reports the evaluation of a homeopathic preparation 'Tinnitus' by a double-blind, placebo-controlled clinical trial. The remedy was taken in tablet form at a homeopathic D60 potency. Perceived intensity and intrusiveness of the tinnitus was assessed at four points during the trial by subjective procedures (visual analogue scales and questionnaires) and by a battery of audiological measurements. Although questionnaire responses indicated that the homeopathic preparation was preferred to placebo by 14 of the 28 subjects, an analysis of variance indicated that neither the VAS scores nor the audiological measures showed significant improvement in tinnitus symptoms in response to 'Tinnitus' versus the placebo. It was concluded that 'Tinnitus' could not be shown to be more effective than the matched placebo.
