Homoeopathic effect on the sleep pattern of rats

Nonlinear dynamical systems effects of homeopathic remedies on multiscale entropy and correlation dimension of slow wave sleep EEG in young adults with histories of coffee-induced insomnia

BACKGROUND

Investigators of homeopathy have proposed that nonlinear dynamical systems (NDS) and complex systems science offer conceptual and analytic tools for evaluating homeopathic remedy effects. Previous animal studies demonstrate that homeopathic medicines alter delta electroencephalographic (EEG) slow wave sleep. The present study extended findings of remedy-related sleep stage alterations in human subjects by testing the feasibility of using two different NDS analytic approaches to assess remedy effects on human slow wave sleep EEG.

METHODS

Subjects (N=54) were young adult male and female college students with a history of coffee-related insomnia who participated in a larger 4-week study of the polysomnographic effects of homeopathic medicines on home-based all-night sleep recordings. Subjects took one bedtime dose of a homeopathic remedy (Coffea cruda or Nux vomica 30c). We computed multiscale entropy (MSE) and the correlation dimension (Mekler-D2) for stages 3 and 4 slow wave sleep EEG sampled in artifact-free 2-min segments during the first two rapid-eye-movement (REM) cycles for remedy and post-remedy nights, controlling for placebo and post-placebo night effects.

RESULTS

MSE results indicate significant, remedy-specific directional effects, especially later in the night (REM cycle 2) (CC: remedy night increases and post-remedy night decreases in MSE at multiple sites for both stages 3 and 4 in both REM cycles; NV: remedy night decreases and post-remedy night increases, mainly in stage 3 REM cycle 2 MSE). D2 analyses yielded more sporadic and inconsistent findings.

CONCLUSIONS

Homeopathic medicines Coffea cruda and Nux vomica in 30c potencies alter short-term nonlinear dynamic parameters of slow wave sleep EEG in healthy young adults. MSE may provide a more sensitive NDS analytic method than D2 for evaluating homeopathic remedy effects on human sleep EEG patterns.

Short-term effects of repeated olfactory administration of homeopathic sulphur or pulsatilla on electroencephalographic alpha power in healthy young adults

INTRODUCTION

Homeopathic pathogenetic trials usually rely on symptom self report measures. Adding objective biomarkers could enhance detection of subtle initial remedy effects. The present feasibility study examined electroencephalographic (EEG) effects of repeated olfactory administration of two polycrest remedies.

METHODS

College student volunteers (ages 18-30, both sexes) from an introductory psychology course were screened for good health and relatively elevated Sulphur or Pulsatilla symptom scores on the Homeopathic Constitutional Type Questionnaire (CTQ). Subjects underwent a series of 3 once-weekly double-blind sessions during which they repeatedly sniffed the remedy matched to their CTQ type and solvent controls. Each remedy was given in a 6c, 12c, and 30c potency, one potency per week, in randomly assigned order. Solvent controls included both plain distilled water and a water-ethanol (95%) solution. All sniff test solutions were further diluted just prior to laboratory sessions (0.5 ml test solution in 150 ml distilled water). Within a session, remedies and control solvents were administered via 2-s sniffs (8 sniffs of each of 4 different succussion levels for the potency in randomized order). Primary outcome variable was relative EEG power (alpha 1 8-10 Hz; alpha 2 10-12 Hz) averaged over 19 electrode sites, including all succussions for a given potency.

RESULTS

Mixed-effect models revealed significant main effects for remedy type (Sulphur >Pulsatilla) in both alpha bands, controlling for gender, baseline resting EEG alpha, and solvent control responses. Additional analyses showed significant nonlinear interactions between dilution and time (weekly session) in alpha 2 for both remedies and alpha 1 for Sulphur.

CONCLUSION

EEG alpha offers an objective biomarker of remedy effects for future studies and potential method for distinguishing time-dependent effects of specific remedies and remedy potencies from one another.

Effects of homeopathic medicines on polysomnographic sleep of young adults with histories of coffee-related insomnia

BACKGROUND

Homeopathy, a common form of alternative medicine worldwide, relies on subjective patient reports for diagnosis and treatment. Polysomnography offers a modern methodology for evaluating the objective effects of taking homeopathic remedies that clinicians claim exert effects on sleep quality in susceptible individuals. Animal studies have previously shown changes in non rapid eye movement sleep with certain homeopathic remedies.

METHODS

Young adults of both sexes (ages 18-31) with above-average scores on standardized personality scales for either cynical hostility or anxiety sensitivity (but not both) and a history of coffee-induced insomnia participated in the month-long study. At-home polysomnographic recordings were obtained on successive pairs of nights once per week for a total of eight recordings (nights 1, 2, 8, 9, 15, 16, 22, 23). Subjects (N=54) received placebo pellets on night 8 (single-blind) and verum pellets on night 22 (double-blind) in 30c doses of one of two homeopathic remedies, Nux Vomica or Coffea Cruda. Subjects completed daily morning sleep diaries and weekly Pittsburgh sleep quality index scales, as well as profile of mood states scales at bedtime on polysomnography nights.

RESULTS

Verum remedies significantly increased PSG total sleep time and NREM, as well as awakenings and stage changes. Changes in actigraphic and self-rated scale effects were not significant.

CONCLUSIONS

The study demonstrated the feasibility of using in-home, all-night sleep recordings to study homeopathic remedy effects. Findings are similar though not identical to those reported in animals with the same remedies. Possible mechanisms include initial disruption of the nonlinear dynamics of sleep patterns by the verum remedies.

Adjunctive care with nutritional, herbal, and homeopathic complementary and alternative medicine modalities in stroke treatment and rehabilitation

This article presents an overview of nutritional, herbal, and homeopathic treatment options from complementary and alternative medicine (CAM) as adjuncts in stroke prevention, treatment, and rehabilitation. Despite many promising leads, the evidence does not favor recommendation of most of these treatments from a public health policy perspective. However, simple preventive interventions such as use of a high-quality multivitamin/multimineral supplement in patients with undernutrition may improve outcomes with minimal long-term risk. Natural agents such as the antioxidant alphalipoic acid, certain traditional Asian herbal mixtures, and some homeopathically prepared remedies show promise for reducing infarct size and associated impairments. A number of nutrients and herbs may assist in treatment of stroke-related complications such as pressure sores, urinary tract infections, and pneumonia. Individualized homeopathy may even play a helpful adjunctive role in treatment of sepsis. However, a great deal of systematic research effort lies ahead before most of the options discussed would meet mainstream medical standards for introduction into routine treatment regimens.

Electroencephalographic Cordance Patterns Distinguish Exceptional Clinical Responders with Fibromyalgia to Individualized Homeopathic Medicines

OBJECTIVES

To characterize initial central nervous system responses to olfactory administration of homeopathic remedies as biomarkers for subsequently exceptional, simillimum-like clinical outcomes at a systemic level (i.e., both locally and globally).

DESIGN

Double-blinded, randomized, placebo-controlled clinical trial.

SETTING

A private homeopathic clinic in Phoenix, AZ, and a university laboratory in Tucson, AZ.

PATIENTS

Sixty-two (62) persons with physician-confirmed fibromyalgia (FM) (mean age, 49 years; 94% women) enrolled; 53 completed the 3-month assessment visit. Exceptional responders (n = 6, 23% of active treatment group; none on placebo) were those with improvements in the top one-third for both tender point pain and global health ratings after 3 months.

INTERVENTION

Patients took daily oral doses of treatment solution in LM (1/50,000 dilution) potency (active group received individualized remedy; placebo group received plain solvent). Dependent measures: Baseline and 3-month difference scores for initial prefrontal electroencephalographic alpha frequency cordance (EEG-C, a correlate of functional brain activity) during 16 pairs of randomized, double-blinded bottle sniffs (treatment minus control solutions).

RESULTS

Exceptional responders versus other patients exhibited significantly more negative initial EEG-C difference scores at prefrontal sites. Right prefrontal cordance findings correlated with subsequently reduced pain (r = 0.85, p = 0.03), better global health (r =-0.73, p = 0.10), and trait absorption (genetically determined ability to focus attention selectively and fully) (r = 0.91, p = 0.012).

CONCLUSIONS

These observations suggest prefrontal EEG-C as an early biomarker of individualized homeopathic medicine effects in patients with FM who later exhibit exceptional outcomes. Prefrontal cortex controls executive function, including ability to redirect attention. Interactions between executive function, absorption, and the simillimum remedy could facilitate exceptional responses.

Mutual information and the homeopathic effect

We explore the feasibility of using mutual information to characterize the homeopathic effect. This quantity measures the information gained about a signal at time (t + tau), from its value at an earlier time t; it quantifies the predictability of data. We illustrate our method with an analysis of the homeopathic effect of Strophanthus hispidus on the cardiac rhythm of healthy human subjects, using data from a previous experiment. Our results allow an intuitively clear rendering and agree with the similitude principle applied to this case. They also show that the solvent has a significant effect on the signal; hence, it does not act as an ideal placebo and we discuss some therapeutic corollaries to this observation.

A kinetic approach to caffeine--Coffea cruda interaction

The biological effect of Coffea cruda 30c was investigated in rats pre and post treated with caffeine. The experimental subjects were male Wistar rats. Caffeine was administered intraperitoneally at the beginning of a sleep period. Coffea cruda 30c (0.1 ml) was administered orally, a contemporaneous control group was tested. The Electroencephalogram (EEG) was recorded in the parietal region during the following sleep cycle. The effect was evaluated by three EEG parameters: the spectral power in delta (0.5-2.5 Hz) and slow 0.32-0.48 Hz bands and the slow/delta power ratio. These markers were analyzed vs time for control and homeopathic groups, blind. In the pretreated set, a similar pattern was identified for control and verum groups up to the 4th hour. From the 5th hour on, power in the delta band was statistically higher in the verum. Spectral power in the slow band and power ratio for the verum group was smaller than the control group from the 6th hour on. In the post-treated set, two verum sub-groups were identified: Post v-A: did not exhibit significant differences from control; Post v-B: displayed an opposite tendency than pre-treatment verum. We conclude that Coffea cruda 30c modifies sleep pattern increasing sleep intensity with pre-treatment. In a subset of the post-treated animals Coffea 30c appeared to reinforce the effects of caffeine.

Comparative effect of Coffea cruda potencies on rats

The effects of Coffea cruda 30 and 200c and caffeine on the sleep pattern of rats were investigated. Treatments were administered orally at the beginning of the sleeping period. EEG from the parietal region was recorded. Delta (0.5-2.5 Hz) and slow (< 1 Hz) waves are two of the major oscillation types that characterize neocortical electrical activity. The spectral power in these bands and the power ratio between 0.32-0.48 Hz and the delta band (slow/delta power ratio) for control and treatment groups were analyzed blind. Power in the delta band was significantly higher than baseline for Coffea 30c and caffeine (15.5mg/kg). An increase in the slow/delta power ratio between control and treatment was detected for Coffea cruda 30 and 200c. Coffea 30c and caffeine have similar effects on sleep pattern, enhancing delta power; Coffea cruda 200c appears to affect only the synchronization.
