The aim of this study was to compare the efficacy of flower therapy for the treatment of anxiety in overweight or obese adults with that of a placebo. The authors examined improvement in sleep patterns, reduction in binge eating, and change in resting heart rate (RHR). This was a randomized, double-blind, placebo-controlled clinical trial with a parallel-group design and two arms. Clinical Research Unit, Medical School, São Paulo State University, Botucatu, SP, Brazil. The study included 40 participants in the placebo group and 41 in the intervention group. Participants were of both genders, from 20 to 59 years of age, overweight or obese, with moderate to high anxiety. The participants were divided into two random groups: one group was treated with Bach flower remedies (BFR) (bottles containing 30 mL of 30% hydro-brandy solution with two drops each of Impatiens, White Chestnut, Cherry Plum, Chicory, Crab Apple, and Pine), and the other group was given a placebo (same solution without BFR). The patients were instructed to orally ingest the solution by placing four drops directly in the mouth four times a day for 4 weeks. : The primary outcome was anxiety (State-Trait Anxiety Inventory [STAI]). Secondary outcomes were sleep (Pittsburgh Sleep Quality Index [PSQI]), binge eating (Binge Eating Scale [BES]), and RHR (electrocardiogram). Multivariate analysis showed significant reductions in scores for the following variables in the intervention group when compared with the placebo group: STAI (β = -0.190; < 0.001), PSQI (β = -0.160; = 0.027), BES (β = -0.226; = 0.001), and RHR (β = -0.07; = 0.003). The anxiety symptoms, binge eating, and RHRs of the individuals treated with flower therapy decreased, and their sleep patterns improved when compared with those treated with the placebo.

本研究旨在比较花疗治疗超重或肥胖成年人焦虑症的疗效与安慰剂的疗效。作者检查了睡眠模式的改善、暴饮暴食的减少和静息心率（RHR）的变化。这是一项随机、双盲、安慰剂对照的临床试验，采用平行分组设计，分为两组。巴西圣保罗州立大学医学院临床研究单位。该研究包括安慰剂组 40 名参与者和干预组 41 名参与者。参与者为 20 至 59 岁的男女，超重或肥胖，有中度至高度焦虑。参与者被分为两组：一组接受 Bach 花疗（BFR）（含 30%白兰地溶液 30ml 的瓶子，每瓶含 Impatiens、White Chestnut、Cherry Plum、Chicory、Crab Apple 和 Pine 各两滴），另一组接受安慰剂（相同溶液不含 BFR）。患者被指示每天口服四次，每次直接将四滴溶液放入口中，持续 4 周。主要结局是焦虑（状态-特质焦虑量表[STAI]）。次要结局是睡眠（匹兹堡睡眠质量指数[PSQI]）、暴饮暴食（暴饮暴食量表[BES]）和 RHR（心电图）。多变量分析显示，与安慰剂组相比，干预组以下变量的评分显著降低：STAI（β=-0.190； <0.001）、PSQI（β=-0.160； =0.027）、BES（β=-0.226； =0.001）和 RHR（β=-0.07； =0.003）。与安慰剂治疗相比，接受花疗治疗的个体的焦虑症状、暴饮暴食和 RHR 下降，睡眠模式改善。在巴西临床试验注册处（注册号 RBR-47-kfxh）注册。
