Homeopathic treatment for premenstrual symptoms

Efficacy of individualized homeopathic medicines in primary dysmenorrhea: a double-blind, randomized, placebo-controlled, clinical trial

OBJECTIVES

Homeopathic treatment is claimed to be beneficial for primary dysmenorrhoea (PD); still, systematic research evidences remain compromised. This study was undertaken to examine the efficacy of individualized homeopathic medicines (IH) against placebo in the treatment of PD.

METHODS

A double-blind, randomized, placebo-controlled trial was conducted at the gynecology outpatient department of Mahesh Bhattacharyya Homoeopathic Medical College and Hospital, West Bengal, India. Patients were randomized to receive either IH (n=64) or identical-looking placebo (n=64). Primary and secondary outcome measures were 0-10 numeric rating scales (NRS) measuring intensity of pain of dysmenorrhea and verbal multidimensional scoring system (VMSS) respectively; all measured at baseline, and every month, up to 3 months. Group differences and effect sizes (Cohen's d) were calculated on intention-to-treat (ITT) sample.

RESULTS

Groups were comparable at baseline (all p>0.05). Attrition rate was 10.9% (IH: 7, placebo: 7). Differences between groups in both pain NRS and VMSS favoured IH over placebo at all time points (all p<0.001, unpaired t-tests and two-ways repeated measures analysis of variance) with medium to large effect sizes. Natrum muriaticum and Pulsatilla nigricans (n=20 each; 15.6%) were the most frequently prescribed medicines. No harms, serious adverse events and intercurrent illnesses were recorded in either of the groups.

CONCLUSIONS

Homeopathic medicines acted significantly better than placebo in the treatment of PD. Independent replication is warranted. Trial registration: CTRI/2018/10/016013.

Effect of Homeopathy on Pain Intensity and Quality Of Life of Students With Primary Dysmenorrhea: A Randomized Controlled Trial

BACKGROUND

Observational studies indicate a positive association between homeopathy and pain relief and quality of life improvement in women with dysmenorrhea. However, there are no interventional studies in this area.

OBJECTIVES

To evaluate an association between homeopathy and pain relief and quality of life improvement in a double-blind placebo-controlled randomized trial with 2 parallel arms.

METHODS

Fifty-four students with primary dysmenorrhea residing at the dormitories of the Tabriz University of Medical Sciences, Iran, who had moderate or severe menstrual pain, were randomized to receive either homeopathic remedy or placebo. The homeopath and participants were blinded to treatment assignment. Primary outcomes were pain intensity and quality of life assessed using a 10-cm visual analog scale and short-form 36 (SF-36), respectively, and the secondary outcome was number of analgesic pills used.

RESULTS

Each group comprised 27 students; eventually, 26 in the homeopathic and 21 in the placebo group were followed up. There was no significant difference between the groups for either pain intensity (adjusted difference: -0.44; 95% CI: -1.43 to 0.54) or any other outcomes. Compared with the baseline scores, statistically significant improvements were observed in pain intensity (P = 0.021) and physical health (P = 0.020) scores only in the homeopathic group; and in the mental health score in both groups (P = 0.014 in the homeopathy group and P = 0.010 in the placebo group).

CONCLUSIONS

This study could not show any significant effect of homeopathy on primary dysmenorrhea in comparison with placebo. Considering the possible effect of the homeopath and the homeopathic remedies prescribed on the results of such interventions, further studies are needed to help us arrive at a conclusion.

Chinese herbal medicine for premenstrual syndrome

BACKGROUND

Traditional Chinese herbal medicines are frequently used to treat premenstrual syndrome (PMS) in China. Until now, their efficacy has not been systematically reviewed.

OBJECTIVES

To evaluate the effectiveness and safety of traditional Chinese herbal medicines in the treatment of women with premenstrual syndrome.

SEARCH STRATEGY

We searched MEDLINE (January 1950 to December, 2007), EMBASE (January 1980 to December, 2007), Chinese Biomedical Database (CBM) (January 1975 to December, 2007), China National Knowledge Infrastructure (CNKI) (January 1994 to December, 2007), and the VIP Database (January 1989 to December, 2007).

SELECTION CRITERIA

Randomised controlled trials (RCTs) studying the efficacy of traditional Chinese herbal medicine(s) for treatment of the premenstrual syndrome were included.

DATA COLLECTION AND ANALYSIS

Two review authors telephoned the original authors of the RCTs to confirm the randomisation procedure, extracted and analysed data from the trials that met the inclusion criteria.

MAIN RESULTS

Two RCT considering 549 women were included. One trial which was identified to be of higher methodological quality demonstrated the therapeutic effectiveness of Jingqianping granule. The other study was considered of lower quality due to the inherent risk of various biases in it. Two studies showed statistically significant differences in elimination of symptoms in proliferative phase and premenstrual phase by taking Jingqianping granule than taking Xiaoyaowan (RR 3.50, 95% CI1.74 to 7.06). Women treated by Cipher decoction had a higher rate of recovery than those taking Co-vitamin B6 capsules (RR 48.99, 95% CI 3.06 to 783.99).

AUTHORS' CONCLUSIONS

It is rare in PMS management that efficacy claims are substantiated by clinical trials. One of the identified trials was well designed and reported on the effectiveness of Jingqianping in the treatment of premenstrual syndrome Qiao 2002. However, currently there is insufficient evidence to support the use of chinese herbal medicine for PMS and further, well controlled, trials are needed before any final conclusions could be drawn.
