Poor sleep quality during pregnancy is a frequent problem. Drug treatment can be problematic due to possible adverse effects for mother and embryo/foetus. Many pregnant women prefer natural treatments and assume that ‘natural’ equals harmless.

In the present study, the sedative effects of Bryophyllum pinnatum were investigated. This remedy is a phytotherapeutic medication predominantly used in anthroposophic medicine. In previous clinical studies on its tocolytic effect, B. pinnatum showed a promising risk/benefit ratio for mother and child. A recent analysis of the prescribing pattern for B. pinnatum in a network of anthroposophic physicians revealed sleep disorders as one of the most frequent diagnosis.

In this prospective, multi-centre, observational study, pregnant women suffering from sleep problems were treated with B. pinnatum (350mg tablets, 50% leaf press juice, Weleda AG, Arlesheim, dosage at physician’s consideration). Sleep quality, daily sleepiness and fatigue were assessed with the aid of standardised questionnaires, at the beginning of the treatment and after 2 weeks. Possible adverse effects perceived by the patients during the treatment were recorded.

The results show that the number of wake-ups, as well as the subjective quality of sleep was significantly improved at the end of the treatment with B. pinnatum. The Epworth Sleeping Scale decreased, indicating a reduction in tiredness during the day. There was, however, no evidence for a prolongation of the sleep duration, reduction in the time to fall asleep, as well as change in the Fatigue Severity Scale after B. pinnatum. No serious adverse drug reactions were detected.

From these data, the authors concluded that B. pinnatum is a suitable treatment of sleep problems in pregnancy. The data of this study encourage further clinical investigations on the use of B. pinnatum in sleep disorders.

Clinical trials of anthroposophic remedies, i.e. remedies which are based on the school of medicine founded by Rudolf Steiner, are very rare. Therefore this trial could be important.

B. pinnatum is a plant used in traditional Tai medicine against hypertension, and to some extend this makes sense: it contains cardiac glycosides which might help lowering elevated blood pressure. The reason for its use as a hypnotic, however, is not clear.

So, is B pinnatum really a ‘suitable treatment of sleep problems in pregnancy’? I doubt it for the following reasons:

  • the effects documented in this study are far from convincing,
  • we would need much more solid data to issue such a general recommendation,
  • cardiac glycosides can cause very serious adverse effects,
  • the sample size of the study is at least one dimension too small for assuming that it is safe,
  • we know nothing about its potential to cause harm to the foetus.

Personally, I find it irresponsible to draw conclusions such as the ones above on the basis of data which are flimsy to the extreme. I ask myself, to what extend wishful thinking might be a regrettable characteristic for the entire field of anthroposophic medicine.

Since weeks I have been searching for new (2013) studies which actually report POSITIVE results. I like good news as much as the next man but, in my line of business, it seems awfully hard to come by. Therefore I am all the more delighted to present these two new articles to my readers.

The first study is a randomized trial with patients suffering from metastatic cancer who received one of three interventions: massage therapy, no-touch intervention or usual care. Primary outcomes were pain, anxiety, and alertness; secondary outcomes were quality of life and sleep. The mean number of massage therapy sessions per patient was 2.8.

The results show significant improvement in the quality of life of the patients who received massage therapy after 1-week follow-up which was not observed in either of the other groups. Unfortunately, the difference was not sustained at 1 month. There were also trends towards improvement in pain and sleep of the patients after massage. No serious adverse events were noted.

The authors conclude that “providing therapeutic massage improves the quality of life at the end of life for patients and may be associated with further beneficial effects, such as improvement in pain and sleep quality. Larger randomized controlled trials are needed to substantiate these findings“.

The second study examined the effectiveness of a back massage for improving sleep quality in 60 postpartum women suffering from poor sleep. They were  randomized to either the intervention or the control group. Participants in both groups received the same care except for the back massages. The intervention group received one 20-minutes back massage at the same time each evening for 5 consecutive days by a certified massage therapist. The outcome measure was the Pittsburgh Sleep Quality Index (PSQI). The results showed that the changes in mean PSQI were significantly lower in the intervention group than in controls indicating a positive effect of massage on sleep quality.

The authors’ conclusions were clear: “an intervention involving back massage in the postnatal period significantly improved the quality of sleep.

Where I was trained (Germany), massage is not deemed to be an alternative but an entirely mainstream treatment. Despite this fact, there is precious little evidence to demonstrate that it is effective. Our own research has found encouraging evidence for a range of conditions, including autism, cancer palliation, constipation, DOMS and back pain. In addition, we have shown that massage is not entirely free of risks but that its potential for harm is very low (some might say that this was never in question but it is good to have a bit more solid evidence).

The new studies are, of course, not without flaws; this can hardly be expected in an area where logistical, financial and methodological problems abound. The fact that there are many different approaches to massage does not make things easier either. The new evidence is nevertheless encouraging and seems to suggest that massage has relaxing effects which are clinically relevant. In my view, massage is a therapy worth considering for more rigorous research.
