Effects of homeopathic treatment in women with premenstrual syndrome: a pilot study.
Alternative therapies in general , and homeopathy in particular , lack clear scientific evaluation of efficacy . Controlled clinical trials are urgently needed , especially for conditions that are not helped by conventional methods . The objective of this work was to assess the efficacy of homeopathic treatment in relieving symptoms associated with premenstrual syndrome ( PMS ) . It was a r and omised controlled double-blind clinical trial . Two months baseline assessment with post-intervention follow-up for 3 months was conducted at Hadassah Hospital outpatient gynaecology clinic in Jerusalem in Israel 1992 - 1994 . The subjects were 20 women , aged 20 - 48 , suffering from PMS .  Homeopathic intervention was chosen individually for each patient , according to a model of symptom clusters . Recruited volunteers with PMS were treated r and omly with one oral dose of a homeopathic medication or placebo . The main outcome measure was scores of a daily menstrual distress question naire ( MDQ ) before and after treatment . Psychological tests for suggestibility were used to examine the possible effects of suggestion . Mean MDQ scores fell from 0.44 to 0.13 ( P<0.05 ) with active treatment , and from 0.38 to 0.34 with placebo ( NS ) . ( Between group P=0.057 ) . Improvement > 30 % was observed in 90 % of patients receiving active treatment and 37.5 % receiving placebo ( P=0.048 ) . Homeopathic treatment was found to be effective in alleviating the symptoms of PMS in comparison to placebo . The use of symptom clusters in this trial may offer a novel approach that will facilitate clinical trials in homeopathy . Further research is in progress
