title: Effects of an anthroposophical remedy on cardiorespiratory regulation.
abstract: BACKGROUND
  The human organism has the inherent ability to regulate and coordinate physiological functions to establish well-being. If this ability is disturbed, eg, in cases of orthostatic syndrome with purely functional disorders, an herbal remedy based on anthroposophical medicine may be able to regulate such rhythmic disturbances.
  
  
  OBJECTIVE
  To determine the effect of the anthroposophical herbal remedy on stimulating the ability to regulate and coordinate physiological functions in healthy subjects.
  
  
  METHODS
  Double-blind, placebo-controlled, randomized trial
  
  
  METHODS
  Ninety-nine healthy subjects; 49 received the remedy, 50 received the placebo.
  
  
  METHODS
  Oral administration of the remedy for 4 weeks, 20 drops 4 times daily.
  
  
  METHODS
  Cardiorespiratory interaction was analyzed by 2 measures: the heart-respiratory ratio and the phase-coordination ratio of heartbeat and respiration. They were calculated from heart rate and respiratory rate, which were derived from 24-hour electrocardiogram recordings before and after the administration of the remedy. Improved normalization of these measures during nighttime sleep after administration of the remedy indicates a stimulation of regulation.
  
  
  RESULTS
  Oral administration of the remedy resulted in an improved normalization of heart-respiratory ratio, phase-coordination ratio and heart rate during nighttime sleep. These results were not observed in the placebo group.
  
  
  CONCLUSIONS
  The remedy stimulates the regulation of cardiorespiratory interaction during nighttime sleep. Furthermore, improved normalization indicates a general improvement of the regulatory processes of functional rhythms.
