Abstract

The aim of this randomized, double-blind, placebo-controlled trial was to investigate the efficacy of ‘Five Flower Remedy’® also known as Rescue Remedy®, for examination anxiety in healthy university students. One hundred university students were recruited. They were registered at the University of Exeter, aged between 18 to 65 years, and enrolled to undertake university examinations between May to July 1998. Participants were randomized to take one to four doses of either ‘Five Flower Remedy’ or indistinguishable placebo during day 1 to 7 of the experiment. Self-reported anxiety was quantified using the 40-item Spielberger State-Trait Anxiety Inventory (STAI) as the primary outcome measure. Visual analogue scales were used as the secondary outcome measure to allow the determination of daily anxiety scores. Forty five percent of volunteers completed the study (21 subjects in the experimental and 24 in the placebo group). Reporting of anxiety, as measured by the state component of the STAI at enrolment, was not found to differ between verum and placebo and no gender differences were noted. However, self-reports of trait anxiety were found to be lower in men compared to women at enrolment. Eight days before examination, men reported significantly lower levels of state anxiety but no significant differences were subsequently identified the evening before the examination. No significant differences were identified between or within groups for mean values of the daily VAS scores or indeed the linear contrast variable constructed to determine any trends associated with the weekly VAS reports. It is concluded that ‘Five Flower Remedy’ had no specific effects in treating anxiety under these trial conditions.

    Citation Excerpt :

    Although the placebo effect appeared to operate in both groups, Rescue® Remedy significantly outperformed the placebo in reducing stress in the subsample characterized from test scores as experiencing a “high” level of anxiety (20). The results of this and similar studies are summarized in Table 1(16, 19, 26–28, 32–34). The term “homeopathy” is a combination of two Greek words: homoios (meaning “similar”) and pathos (“suffering”).

    Citation Excerpt :

    Like other complementary medicines, flower essences are a spiritually contextualized therapy [32], and the spiritual nature of flower essences was part of the rationale presented by their inventor, Edward Bach [33]. From a biochemical perspective, all 38 essences are identical (brandy 60% and water 40%), and no difference has been detected between verum and placebo [34,35]. Flower essences can be considered a self-help placebo, which is used regularly for clinical purposes.

    The above two studies did not investigate expectancy directly. Flower essence therapy is related to homeopathy and the only two double-blind placebo-controlled trials of this therapy have failed to find a difference between placebo and verum [26,27]. In an open study [28], 116 university students and staff were offered free flower essences in return for completed questionnaires and evaluation.
