Background
Rudolf Steiner (1861–1925) created, among other things, the Waldorf schools, biodynamic farming and his own philosophy, known as anthroposophy. Applying his philosophical concepts to health, he founded, together with Dr Ita Wegman, an entirely new school of medicine. It assumes metaphysical relations between planets, metals and human organs, which provide the basis for therapeutic strategies. Diseases are believed to be related to actions in previous lives; in order to redeem oneself, it may be best to live through them without conventional therapy. Instead a range of other therapeutic modalities is employed in anthroposophic medicine: herbal extracts, art therapy, massage, exercise therapy and other unconventional approaches.
The best-known anthroposophic remedy is a fermented mistletoe extract which is used to treat cancer. Steiner argued that mistletoe is a parasitic plant which eventually kills its host — a striking resemblance to a malignant tumour which also lives off its host and finally kills him/her. His conclusion, therefore, was that mistletoe can be used to treat cancer. The concepts of anthroposophic medicine are biologically implausible.
What is the evidence?
The efficacy of mistletoe preparations remains unproven — either for curing cancer or for improving the quality of life of cancer patients. Other elements of the anthroposophical concept are not well researched, and the therapeutic concept as a whole has so far not been rigorously tested.
Mistletoe injections have been associated with a range of adverse effects. The most important risk, however, is that of discarding conventional treatments. For example, anthropospohical doctors tend to advise parents against the immunization of their children, and some cancer patients forfeit conventional treatment for mistletoe extracts.
Conclusion
Anthroposophic medicine is biologically implausible, it has not been shown to be effective, and it is unlikely to work. It can also carry considerable risks.
Aromatherapy
Background
Plant oils have been used in several ancient cultures, but the birth of aroma therapy proper was not until the publication of a book entitled
There are several ways of using essential oils. Most commonly, the diluted oil is applied to the skin via a gentle massage, but the oil can also be added to a bath or diffused in the ambient air. If combined with a massage, aromatherapy is definitely relaxing — but it is unclear whether the effect is caused by the oil, the gentle massage or both. Aromatherapists believe that different essential oils have different specific effects. Therefore therapists individualize these oils according to their patient’s characteristics, symptoms, etc.
A consultation with an aromatherapist can last between one and two hours. The therapist will normally take a brief medical history, possibly conduct a short examination and then proceed by massaging a diluted essential oil into the skin of the patient. This process is relaxing and, for most people, agreeable. Aromatherapy is often advocated for chronic conditions such as anxiety, tension headache and musculoskeletal pain. Aromatherapists usually recommend regular sessions, even in the absence of symptoms, e.g. for preventing recurrences.
What is the evidence?
Some clinical trials confirm the relaxing effects of aromatherapy massage. However, these effects are usually shortlived and therefore of debatable therapeutic value. Some essential oils do seem to have specific effects. For instance, tea tree has antimicrobial properties. However, these are far less reliable than those of conventional antibiotics. The risks of aromatherapy are minimal, such as the possibility that some patients may be allergic to some essential oils.
