Homeopathy no more effective than placebos, a study .... finds.

Homeopathy is no more effective in treating health conditions than placebos, a study by the National Health and Medical Research Council (NHMRC) has found.
NHMRC released the findings after assessing 1,800 papers which examined the efficacy of the alternative "medicine". Homeopathic practitioners believe substances which may cause illness in a healthy person can, in very small doses, treat those symptoms. They also think molecules in a highly diluted form retain a "memory" of the original substance.
The NHMRC found of the studies examined, only 225 were included in the review, as the scientific quality of other studies was limited.The review found homeopathy was not any more effective than a placebo, or sugar pill, in treating common medical conditions such as headaches, asthma, anxiety, attention deficit disorder, and ulcers.
