Clinical trial, with positive findings, on 40 women following childbirth at a medical centre in Israel. Approximately half of the women were randomly allocated to receive the homeopathic medicines Arnica and Bellis perennis, and the others received a dummy pill (placebo); they were not told which treatment group they were in. After 3 days, the women who received homeopathy had evidence of having lost less blood than those who received placebo.
