Backgound: Homeopathy is a medical theory and practice that asserts that disease can be cured by remedies that produce symptoms in a healthy person similar to those suffered by a patient with a malady.
Methods: The aim of this study was to investigate effects of homeopathic Anax imperator (dragonfly) (Anax-i 30c and Anax-i 200c) in the forced swim test (FST), elevated plus-maze (EPM) test, hot plate (HP) test and open field test and examined NPY1 receptor expression, in naive mice.
Results: In the FST, treatment with Anax-i 30c or Anax-i 200c significantly diminished immobility time while in EPM test, Anax-i 200c increased the percentage of time spent in open arms as well as the percentage of open arm/total arms. In the HP test, Anax-i 30c or Anax-i 200c decreased the total time mice spent licking their hind paws while in open field test, treatment with Anax-i 200c increased the total distance and speed mice traveled compared to the control group. Three weeks of daily injections with Anax-i 30c or Anax-i 200c caused significant weight loss in mice. Anax-i 30c or Anax-i 200c treatment significantly decreased NPY1 receptor expression, and Anax-i 30c also decreased NPY2 receptor expression.
Conclusion: These results suggest that the homeopathic Anax-i exerts antidepressant, anxiolytic and analgesic-like effects and causes hyperlocomotion and weight loss.
