The effect of the homeopathic remedies Arnica montana and Bellis perennis on mild postpartum bleeding--a randomized, double-blind, placebo-controlled study--preliminary results.

Objective: To evaluate the effect of Arnica Montana and Bellis perennis on postpartum blood loss.

Design: Double blind, placebo-controlled, randomized, clinical trial.

Setting: Department of Gynecology, Shaare Zedek Medical Center, Jerusalem.

Interventions: Forty parturients were randomized to one of three groups: Arnica montana C6 and Bellis perennis C6 (n=14), Arnica montana C30 and Bellis perennis C30 (n=14), or double placebo (n=12). After 48 h the Arnica/placebo was halted, and patients continued the Bellis/placebo until cessation of lochia.

Main Outcome Measures: Hemoglobin levels (Hb) at 48 and 72 h postpartum.

Results: At 72 h postpartum, mean Hb levels remained similar after treatment with homeopathic remedies (12.7 versus 12.4) as compared to a significant decrease in Hb levels in the placebo group (12.7 versus 11.6; p<0.05), in spite of less favorable initial characteristics of the treatment group. The mean difference in Hb levels at 72 h postpartum was -0.29 (95% CI -1.09; 0.52) in the treatment group and -1.18 (95% CI -1.82; -0.54) in the placebo group (p<0.05).

Conclusion: Treatment with homeopathic Arnica montana and Bellis perennis may reduce postpartum blood loss, as compared with placebo.
