Homeopathic Preparations of Quartz, Sulfur and Copper Sulfate Assessed by UV-Spectroscopy.

Homeopathic preparations are used in homeopathy and anthroposophic medicine. Although there is evidence of effectiveness in several clinical studies, including double-blinded randomized controlled trials, their nature and mode of action could not be explained with current scientific approaches yet. Several physical methods have already been applied to investigate homeopathic preparations but it is yet unclear which methods are best suited to identify characteristic physicochemical properties of homeopathic preparations. The aim of this study was to investigate homeopathic preparations with UV-spectroscopy. In a blinded, randomized, controlled experiment homeopathic preparations of copper sulfate (CuSO(4); 11c-30c), quartz (SiO(2); 10c-30c, i.e., centesimal dilution steps) and sulfur (S; 11×-30×, i.e., decimal dilution steps) and controls (one-time succussed diluent) were investigated using UV-spectroscopy and tested for contamination by inductively coupled plasma mass spectrometry (ICP-MS). The UV transmission for homeopathic preparations of CuSO(4) preparations was significantly lower than in controls. The transmission seemed to be also lower for both SiO(2) and S, but not significant. The mean effect size (95% confidence interval) was similar for the homeopathic preparations: CuSO(4) (pooled data) 0.0544% (0.0260-0.0827%), SiO(2) 0.0323% (-0.0064% to 0.0710%) and S 0.0281% (-0.0520% to 0.1082%). UV transmission values of homeopathic preparations had a significantly higher variability compared to controls. In none of the samples the concentration of any element analyzed by ICP-MS exceeded 100 ppb. Lower transmission of UV light may indicate that homeopathic preparations are less structured or more dynamic than their succussed pure solvent.

Investigation of arsenic-stressed yeast (Saccharomyces cerevisiae) as a bioassay in homeopathic basic research.

This study investigated the response of arsenic-stressed yeast (Saccharomyces cerevisiae) towards homeopathically potentized Arsenicum album, a duckweed nosode, and gibberellic acid. The three test substances were applied in five potency levels (17x, 18x, 24x, 28x, 30x) and compared to controls (unsuccussed and succussed water) with respect to influencing specific growth parameters. Five independent experiments were evaluated for each test substance. Additionally, five water control experiments were analyzed to investigate the stability of the experimental setup (systematic negative control experiments). All experiments were randomized and blinded. Yeast grew in microplates over a period of 38 h in either potentized substances or water controls with 250 mg/l arsenic(V) added over the entire cultivation period. Yeast's growth kinetics (slope, Et50, and yield) were measured photometrically. The test system exhibited a low coefficient of variation (slope 1.2%, Et50 0.3%, yield 2.7%). Succussed water did not induce any significant differences compared to unsuccussed water. Data from the control and treatment groups were both pooled to increase statistical power. In this study with yeast, no significant effects were found for any outcome parameter or any homeopathic treatment. Since in parallel experiments arsenic-stressed duckweed showed highly significant effects after application of potentized Arsenicum album and duckweed nosode preparations from the same batch as used in the present study, some specific properties of this experimental setup with yeast must be responsible for the lacking response.

Use of homeopathic preparations in experimental studies with abiotically stressed plants.

BACKGROUND: Experimental research on the effects of homeopathic treatments on impaired plants was last reviewed in 1990. OBJECTIVES: To compile a systematic review of the existing literature on basic research in homeopathy with abiotically stressed plants using predefined criteria. METHODS: The literature search was carried out on publications that reported experiments on homeopathy using abiotically stressed whole plants, seeds, plant parts and cells from 1920 to 2010. Outcomes had to be measured by established procedures and statistically evaluated. Using of a Manuscript Information Score (MIS) we identified those publications that provided sufficient information for proper interpretation (MIS≥5). A further evaluation was based on the use of adequate controls to investigate specific effects of homeopathic preparations and on the use of systematic negative control experiments. RESULTS: A total of 34 publications with abiotically stressed plants was identified, published between 1965 and 2010. The 34 publications described a total of 37 experimental studies. Twenty-two studies included statistics, 13 had a MIS≥5, 8 were identified with adequate controls and 4 with negative control experiments. Significant and reproducible effects with decimal and centesimal potencies were found, including dilution levels beyond Avogadro's number. One experimental model was independently assessed by another research team and yielded inverted results compared to the original trial. CONCLUSIONS: Abiotically stressed plant models seem to be a useful approach to investigate homeopathic basic research questions, but more experimentation and especially more independent replication trials are needed. Systematic negative control experiments should be implemented on a routine basis to exclude false-positive results.

Usage of alternative medical systems, acupuncture, homeopathy and anthroposophic medicine, by older German adults.

OBJECTIVE: The manifold studies on the usage of complementary and alternative medicine (CAM) indicate that its utilization differs with respect to socio-cultural background, gender, age and underlying disease. This study intended to analyze the usage of specific CAM practices among a population of older German adults with health insurance coverage. METHODS: Data of 5 830 older individuals who participated in an anonymous cross sectional survey among German insurance beneficiaries were analyzed with respect to usage of CAM treatments applied by medical doctors or non-medical practitioners within the last 5 years. RESULTS: The most frequently used approaches were acupuncture/traditional Chinese medicine (21%), homeopathy (21%), movement therapies/physical exercises (19%), osteopathy/chiropractic (12%), herbs/phytotherapy (7%), diets/specific food recommendations (6%) and foot reflexology (5%). Anthroposophic medicine was used only to a minor degree. Acupuncture and homeopathy users were likely to choose more than one CAM treatment simultaneously, particularly the combination of homeopathy and acupuncture. Moreover, this study can confirm significant differences between women and men in the use of the main relevant CAM interventions. CONCLUSION: The relative proportion of acupuncture usage was similar to homeopathy, which is an alternative whole medical system originating from Western Europe. This means that an Eastern alternative system is established also in Germany. In several cases not only one CAM treatment was used but distinct combinations existed (particularly homeopathy and acupuncture); thus one should be cautious to draw predictive conclusions from studies with broad and unspecific CAM categories, for among them there are several therapies which should not be regarded as CAM.

How should complementary and alternative medicine be taught to medical students in Switzerland? A survey of medical experts and students.

BACKGROUND: In Switzerland and in the whole western world, the growing popularity of CAM is calling for its implementation in the undergraduate medical curriculum. AIMS: To determine whether medical experts and medical students are favorable to complementary and alternative medicine (CAM) education at Swiss medical schools and to investigate their opinion about its form, content and goals. METHODS: Experts in the fields of conventional medicine (COM, n = 106), CAM experts (n = 29) and senior medical students (n = 640) were surveyed by an online questionnaire. RESULTS: 48.7% of the COM experts, 100% of the CAM experts, and 72.6% of the students are favorable to CAM education at Swiss medical schools. The most requested disciplines are acupuncture, phytotherapy, and homeopathy; the most recommended characteristics of CAM education are elective courses, during the clinical years, in the format of seminars and lectures. For the CAM experts, the priority is to improve the students' knowledge of CAM, whereas for the COM experts and the students, the priority is to analyze efficiency, security, interactions, and secondary effects of CAM. CONCLUSIONS: CAM courses should be informative, giving the students sufficient knowledge to provide a critical analysis of efficiency and security of different CAM modalities.

Effects of homeopathic arsenicum album, nosode, and gibberellic acid preparations on the growth rate of arsenic-impaired duckweed (Lemna gibba L.).

This study evaluated the effects of homeopathically potentized Arsenicum album, nosode, and gibberellic acid in a bioassay with arsenic-stressed duckweed (Lemna gibba L.). The test substances were applied in nine potency levels (17x, 18x, 21x-24x, 28x, 30x, 33x) and compared with controls (unsuccussed and succussed water) regarding their influence on the plant's growth rate. Duckweed was stressed with arsenic(V) for 48 h. Afterwards, plants grew in either potentized substances or water controls for 6 days. Growth rates of frond (leaf) area and frond number were determined with a computerized image analysis system for different time intervals (days 0-2, 2-6, 0-6). Five independent experiments were evaluated for each test substance. Additionally, five water control experiments were analyzed to investigate the stability of the experimental setup (systematic negative control experiments). All experiments were randomized and blinded. The test system exhibited a low coefficient of variation (approximately equal to 1%). Unsuccussed and succussed water did not result in any significant differences in duckweed growth rate. Data from the control and treatment groups were pooled to increase statistical power. Growth rates for days 0-2 were not influenced by any homeopathic preparation. Growth rates for days 2-6 increased after application of potentized Arsenicum album regarding both frond area (p < 0.001) and frond number (p < 0.001), and by application of potentized nosode (frond area growth rate only, p < 0.01). Potencies of gibberellic acid did not influence duckweed growth rate. The systematic negative control experiments did not yield any significant effects. Thus, false-positive results can be excluded with high certainty. To conclude, the test system with L. gibba impaired by arsenic(V) was stable and reliable. It yielded evidence for specific effects of homeopathic Arsenicum album preparations and it will provide a valuable tool for future experiments that aim at revealing the mode of action of homeopathic preparations. It may also be useful to investigate the influence of external factors (e.g., heat, electromagnetic radiation) on the effects of homeopathic preparations.

Effects of exposure to physical factors on homeopathic preparations as determined by ultraviolet light spectroscopy.

Clinical trials have reported statistically significant and clinically relevant effects of homeopathic preparations. We applied ultraviolet (UV) spectroscopy to investigate the physical properties of homeopathic preparations and to contribute to an understanding of the not-yet-identified mode of action. In previous investigations, homeopathic preparations had significantly lower UV light transmissions than controls. The aim of this study was to explore the possible effects of external factors (UV light and temperature) on the homeopathic preparations. Homeopathic centesimal (c) dilutions, 1c to 30c, of copper sulfate (CuSO(4)), decimal dilutions of sulfur (S(8)), 1x to 30x, and controls (succussed potentization medium) were prepared, randomized, and blinded. UV transmission was measured at six different time points after preparation (from 4 to 256 days). In addition, one series of samples was exposed to UV light of a sterilization lamp for 12 h, one was incubated at 37 degrees Celsius for 24 h, and one was heated to 90 degrees Celsius for 15 min. UV light transmission values from 190 or 220 nm to 340 nm were measured several times and averaged. After each exposure, UV transmission of the homeopathic preparations of CuSO(4) was significantly reduced compared to the controls, particularly after heating to 37 degrees Celsius. Overall, the nonexposed CuSO(4) preparations did not show significantly lower UV transmission compared to controls; however, the pooled subgroup of measurements at days 26, 33, and 110 yielded significant differences. UV light transmission for S(8) preparations did not show any differences compared to controls. Our conclusion is that exposure to external factors, incubation at 37 degrees Celsius in particular, increases the difference in light transmission of homeopathic CuSO(4) preparations compared to controls.

High-field 1H T(1) and T(2) NMR relaxation time measurements of H2O in homeopathic preparations of quartz, sulfur, and copper sulfate.

Quantitative meta-analyses of randomized clinical trials investigating the specific therapeutic efficacy of homeopathic remedies yielded statistically significant differences compared to placebo. Since the remedies used contained mostly only very low concentrations of pharmacologically active compounds, these effects cannot be accounted for within the framework of current pharmacology. Theories to explain clinical effects of homeopathic remedies are partially based upon changes in diluent structure. To investigate the latter, we measured for the first time high-field (600/500 MHz) 1HT(1) and T(2) nuclear magnetic resonance relaxation times of H2O in homeopathic preparations with concurrent contamination control by inductively coupled plasma mass spectrometry (ICP-MS). Homeopathic preparations of quartz (10c-30c, n = 21, corresponding to iterative dilutions of 100(-10)-100(-30)), sulfur (13x-30x, n = 18, 10(-13)-10(-30)), and copper sulfate (11c-30c, n = 20, 100(-11)-100(-30)) were compared to n = 10 independent controls each (analogously agitated dilution medium) in randomized and blinded experiments. In none of the samples, the concentration of any element analyzed by ICP-MS exceeded 10 ppb. In the first measurement series (600 MHz), there was a significant increase in T(1) for all samples as a function of time, and there were no significant differences between homeopathic potencies and controls. In the second measurement series (500 MHz) 1 year after preparation, we observed statistically significant increased T(1) relaxation times for homeopathic sulfur preparations compared to controls. Fifteen out of 18 correlations between sample triplicates were higher for controls than for homeopathic preparations. No conclusive explanation for these phenomena can be given at present. Possible hypotheses involve differential leaching from the measurement vessel walls or a change in water molecule dynamics, i.e., in rotational correlation time and/or diffusion. Homeopathic preparations thus may exhibit specific physicochemical properties that need to be determined in detail in future investigations.

Homeopathic treatment of Arabidopsis thaliana plants infected with Pseudomonas syringae.

Homeopathic basic research is still in the screening phase to identify promising model systems that are adapted to the needs and peculiarities of homeopathic medicine and pharmacy. We investigated the potential of a common plant-pathogen system, Arabidopsis thaliana infected with the virulent bacteria Pseudomonas syringae, regarding its response towards a homeopathic treatment. A. thaliana plants were treated with homeopathic preparations before and after infection. Outcome measure was the number of P. syringae bacteria in the leaves of A. thaliana, assessed in randomized and blinded experiments. After a screening of 30 homeopathic preparations, we investigated the effect of Carbo vegetabilis 30x, Magnesium phosphoricum 30x, Nosode 30x, Biplantol (a homeopathic complex remedy), and Biplantol 30x on the infection rate in five or six independent experiments in total. The screening yielded significant effects for four out of 30 tested preparations. In the repeated experimental series, only the homeopathic complex remedy Biplantol induced a significant reduction of the infection rate (p = 0.01; effect size, d = 0.38). None of the other four repeatedly tested preparations (Carbo vegetabilis 30x, Magnesium phosphoricum 30x, Nosode 30x, Biplantol 30x) yielded significant effects in the overall evaluation. This phytopathological model yielded a small to medium effect size and thus might be of interest for homeopathic basic research after further improvement. Compared to Bion (a common SAR inducer used as positive control), the magnitude of the treatment effect of Biplantol was about 50%. Thus, homeopathic formulations might have a potential for the treatment of plant diseases after further optimization. However, the ecological impact should be investigated more closely before widespread application.

Isopathic treatment effects of Arsenicum album 45x on wheat seedling growth--further reproduction trials.

BACKGROUND: Two experimental studies on wheat preintoxicated with Arsenic trioxide yielded a significant shoot growth increase after an isopathic application of Ars-alb 45x. One independent reproduction trial however, yielded an effect inversion: wheat shoot growth was significantly decreased after application of Ars-alb 45x. AIMS: In this study we investigated the role of three potential confounding factors on the experimental outcome: geographical location of the experiments, influence of the main experimenter, and seed sensitivity to Arsenic poisoning. Laboratory-internal reproducibility was assessed by meta-analysis. MATERIAL AND METHODS: Wheat poisoned with Arsenic trioxide was cultivated in vitro in either Ars-alb 45x, water 45x, or unpotentised water. Treatments were blinded and randomised. Shoot length was measured after 7 days. The stability of the experimental set-up was assessed by systematic negative control (SNC) experiments. RESULTS: The SNC experiments did not yield significant differences between the three groups treated with unpotentised water. Thus the experimental set-up seemed to be stable. We did not observe any shoot growth increase after a treatment with Ars-alb 45x in any of the newly performed experiments. In contrast, the meta-analysis of all 17 experiments performed (including earlier experiments already published) yielded a statistically significant shoot growth decrease (-3.2%, p=0.017) with isopathic Ars-alb 45x treatment. This effect was quantitatively similar across all five series of experiments. CONCLUSIONS: Ultramolecular Ars-alb 45x led to statistically significant specific effects in arsenic poisoned wheat when investigated by two independent working groups. Effect size and effect direction differ, however. The investigated factors (geographical location, experimenter, seed sensitivity to Arsenic poisoning) did not seem to be responsible for the effect inversion. Laboratory external reproducibility of basic research into homeopathic potentisation remains a difficult issue.

Reproducibility of dwarf pea shoot growth stimulation by homeopathic potencies of gibberellic acid.

OBJECTIVES: Investigation of the conditions for reproducibility of dwarf pea shoot growth stimulation through homeopathic potencies of gibberellic acid. METHODS: 4 batches of pea seed (Pisum sativum L. cv. Früher Zwerg; harvests from 1997, 1998, 1999, and 2000) were tested regarding their reaction to gibberellic acid 17x and 18x (compared to unsuccussed and succussed water (1x) as controls) in 8 independent randomized and blinded experiments. Pea seed was immersed for 24h in watery solutions of homeopathic potencies or controls, and cultivated under controlled laboratory conditions. Pea shoot length was measured after 14 days. Two systematic negative control experiments assessed the stability of the experimental set-up. RESULTS: The systematic negative control experiments yielded no significant effects and confirmed the stability of the experimental set-up. 2 out of 4 seed batches reacted to the homeopathic treatment (p<0.05). Seed batch 1997 showed a reproducible reaction to gibberellic acid 17x (shoot length stimulation of +11.2%, p=0.007), and seed batch 1998 showed a significant varying response (increase/decrease). Seed batch 1997 differed from the other 3 batches by an increased glucose and fructose content, and reduced 1000kernel weight. Meta-analysis with data of earlier experiments is in accordance with the results of the present experimental series. CONCLUSIONS: We identified 'seed quality' as a possible trigger factor for successful reproducibility in homeopathic basic research. Premature harvesting as a possible key factor for responsiveness of dwarf peas to homeopathic potencies of gibberellic acid is our current working hypothesis to be tested in future experiments.

Development of a whole plant bioassay to test effects of potentized calcium carbonate in pillule formulation.

OBJECTIVES: From a pharmaceutical point of view, we see a need to develop stable preclinical test systems to identify and investigate effects of potentized remedies as used in Anthroposophic Medicine and Homeopathy. We evaluated a plant bioassay regarding its capacity to distinguish homeopathic remedies from placebo, applied as sucrose pillules. METHODS: Pea seed (Pisum sativum L) was soaked for 24 hours in water with dissolved homeopathic or placebo pillules, or in water only. Shoot length was measured 14 days after planting and treatment groups were compared by analysis of variance (ANOVA). The stability of the system was validated by systematic negative control experiments. RESULTS: The system is suitable to test a common application form - sucrose pillules - of a potentized preparation without influence of the pharmaceutical carrier substance. A screening of 13 potentized preparations revealed Calcium carbonicum to affect pea shoot growth (p < 0.05). Three independent series of main experiments were performed with potentized Calcium carbonicum to assess reproducibility. Meta-analysis of all data revealed significant effects of Calcium carbonicum 12c and 30c on pea shoot growth (p < 0.05), which were however dependent on the date of experiment and/or the experimental series. CONCLUSIONS: Potentized Calcium carbonicum, applied as sucrose pillules, influenced pea shoot growth in the assay investigated. However, due to the small effect size and due to the modulation of the effects by still unknown external factors, further optimization of this bioassay is necessary to be used in pharmaceutical quality control or in investigating the biological or pharmaceutical mode of action of potentized preparations.

Replication study concerning the effects of homeopathic dilutions of histamine on human basophil degranulation in vitro.

BACKGROUND: Various investigators have observed significant effects of highly diluted histamine on human basophil degranulation in vitro, compared to corresponding water controls. However, active and inactive dilution levels differed in most studies. OBJECTIVE: We aimed to reproduce former studies with flow-cytometry using rigorously controlled experimental conditions to minimise confounding factors. METHODS: In seven independent experiments, basophils of the same human donor were incubated with diluted histamine (up to 10(-34)M) or water controls and activated with anti-IgE antibodies. Basophil activation was determined by using bi-colour flow-cytometry. Experiments were blinded and performed with a randomised arrangement of the solutions on microtiter-plates. RESULTS: Histamine at the dilutions 10(-2)M and 10(-22)M was associated with a significant inhibition of basophil degranulation (p=0.018, Wilcoxon signed rank test) of 23.1% and 5.7%, respectively, if compared to "diluted" water treated in an identical manner. However, if all controls were pooled, only histamine 10(-2)M had a significant effect. Significant effects were seen for row numbers of the microtiter plates. CONCLUSION: We were not able to confirm the previously reported large effects of homeopathic histamine dilutions on basophil function of the examined donor. Seemingly, minor variables of the experimental set up can lead to significant differences of the results if not properly controlled.

Does homeopathically potentized antimony stimulate coagulation? A summary of previous findings and results of an in vitro pilot study by means of thrombelastography.

BACKGROUND: Potentized antimony is traditionally used in anthroposophic medicine to enhance hemostasis in bleeding disorders, but evidence of its effectiveness is scarce. On the other hand, non-toxic and economic additional therapeutic options for hemostatic disorders are desirable. OBJECTIVES: We examined all available literature on the subject and performed a controlled pilot in vitro study to test the procoagulatory potency of antimony D 5. DESIGN: Freshly drawn citrated whole blood of 12 healthy volunteers and 12 patients with bleeding disorders was equally distributed into 344 portions, after which it was mixed with antimony D 5, or its potentized vehicle (lactose D 5) as control solution and tested with thrombelastography. The paired t-test and the Wilcoxon signed rank test were used for statistical analysis. In 5 of the 12 healthy donors, a second blood sample was drawn to assess individual variability and increase the total number of replicates. Thus three separate calculations were performed: for the 12 patients, the 12 healthy donors, and the 5 later samples from the same donors. The analysis was exploratory, and no Bonferroni correction was applied. RESULTS: In the antimony D5 samples of the 12 healthy subjects, but not the patients, there was a tendency toward a shorter clotting time (CT) (p = 0.074) and a trend for an increased clot firmness, expressed as maximal amplitude (MA) (p = 0.058). The increase of MA was significant (p = 0.011) when the later samples were included. No statistical difference was detected for the clot formation time and the clot lysis index. CONCLUSION: The exploratory results of this pilot study are inconclusive as to whether antimony D5 has a procoagulatory effect in vitro, although the results suggest an effect on MA and possibly CT. More research is warranted.

Development of a test system for homeopathic preparations using impaired duckweed (Lemna gibba L.).

OBJECTIVES: A bioassay with arsenic-stressed duckweed (Lemna gibba L.) was developed to study potentially regulative effects of homeopathic preparations. We compared potentized substances (nine different potency levels between 17 x and 33 x ) with two controls (unsuccussed and succussed water) regarding their influence on number- and area-related growth rate and color of fronds (leaves). Screening included 11 potentized substances: Arsenicum album, gibberellic acid, nosode, arsenic(V), phosphorus, Conchae, Acidum picrinicum, Argentum nitricum, Crotalus horridus, Hepar sulfuris, and Mercurius vivus naturalis. DESIGN: Duckweed was stressed with arsenic(V) for 48 hours. Afterwards, plants grew in either potentized substances or water controls for 6 days. Growth rate and color of fronds were determined with a computerized image analysis system for different time intervals (days 0-2, 2-6, 0-6). A systematic negative control experiment with unsuccussed water was used to investigate the stability of the bioassay. All experiments were randomized and blinded. RESULTS: Arsenicum album and nosode potencies increased frond number-related growth rate compared to controls (succussed water controls or pooled water controls [succussed and unsuccussed], p < 0.05, t test). Regarding color classification, no effects were observed. CONCLUSIONS: The experimental setup with L. gibba stressed by arsenic(V) provides a valuable tool to investigate regulative effects of potentized substances. In order to verify the effects of Arsenicum album and nosode potencies, further independent replication experiments are necessary.

Efficacy of homeopathically potentized antimony on blood coagulation. A randomized placebo controlled crossover trial.

BACKGROUND: Homeopathically potentized antimony 6x is traditionally used in anthroposophic medicine for an alleged pro-coagulatory effect in bleeding disorders. However, the scientific evidence base is yet insufficient. Results of a previous in vitro study suggested a slight increase of maximal clot firmness (MCF) and a tendency towards a shorter clotting time (CT). The objective of this study was to investigate the pro-coagulatory effects of antimony in vivo, and possible unexpected or adverse events. PARTICIPANTS AND METHODS: A randomized placebo controlled double blind crossover study was carried out in 30 healthy volunteers (15 males, 15 females). Each participant received intravenously 10 ml of antimony 6x and placebo in a randomized order at an interval of 1 month. Thrombelastography (TEG) was carried out immediately before and 30 and 60 min after the injection. RESULTS: Statistically significant pro-coagulatory effects were observed 30 min after injection for CT in men (p = 0.0306), and for MCF in men and women combined (p = 0.0476). The effect of antimony was significantly larger on test day 1 than on test day 2, whereas the effect of placebo was similar on both test days. No unexpected adverse or adverse events causally related to antimony were observed. CONCLUSION: This study adds evidence to the hypothesis that homeopathically potentized antimony may be efficacious in vivo. The consistency of the results with previous in vitro results indicates an effect on MCF and CT. The in vivo application of antimony 6x is safe.

Palliative in-patient cancer treatment in an anthroposophic hospital: I. Treatment patterns and compliance with anthroposophic medicine.

BACKGROUND: Complementary and alternative medicine (CAM) and most of all anthroposophic medicine (AM) are important features of cancer treatment in Switzerland. While the number of epidemiological investigations into the use of such therapies is increasing, there is a distinct lack of reports regarding the combination of conventional and CAM methods. PATIENTS AND METHODS: 144 in-patients with advanced epithelial cancers were enrolled in a prospective quality-of-life (QoL) study at the Lukas Klinik (LK), Arlesheim, Switzerland. Tumor-related treatment was assessed 4 months prior to admission, during hospitalization and 4 months after baseline. OBJECTIVE: We aimed at giving a detailed account of conventional, AM and CAM treatment patterns in palliative care, before, during and after hospitalization, with emphasis on compliance with AM after discharge. RESULTS: Certain conventional treatments featured less during hospitalization than before but were resumed after discharge (chemotherapy, radiotherapy, sleeping pills, psychoactive drugs). Hormone therapy, corticosteroids, analgesics WHO III and antidepressants remained constant. AM treatment consisted of Iscador? (mistletoe), other plant- or mineral-derived medication, baths, massage, eurythmy, art therapy, counseling and lactovegetarian diet. Compliance after discharge was highest with Iscador (90%) and lowest with art therapy (14%). Many patients remained in the care of AM physicians. Other CAM and psychological methods were initially used by 39.9% of patients. After 4 months, the use had decreased with few exceptions. CONCLUSION: During holistic palliative treatment in an anthroposophic hospital, certain conventional treatments featured less whereas others remained constant. After discharge, chemotherapy returned to previous levels, AM compliance remained high, the use of other CAM therapies low.
