Practices with poor prescribing performance more likely to prescribe homeopathy

A study by researchers at the University of Oxford and Exeter University found that general practices in England with the worst prescribing quality scores are 2.1 times more likely to prescribe homeopathy than those with the best scores. Poor prescribing performance is strongly associated with homeopathy use, but not with patient outco...

Insufficient evidence to support use of homeopathy in livestock

A comprehensive review of homeopathy in livestock found that many clinical trials have methodological limitations, making it difficult to draw conclusions about its effectiveness. The review suggests that more research is needed to fully understand the potential benefits and risks of using homeopathy in food-producing animals.

Survey examines Americans' use of and satisfaction with homeopathic medicines

A survey of Americans' use of homeopathic medicines found that they are primarily used for common self-limited conditions such as the common cold or back pain. Homeopathy users tend to be more likely to use complementary and integrative medicine modalities, and report finding these products helpful in addressing their health problems.

Should doctors recommend homeopathy?

Peter Fisher argues that homeopathy is misunderstood and that some reviews have omitted key evidence, while Edzard Ernst claims that most independent systematic reviews have failed to show homeopathy's effectiveness due to methodological flaws.

Many brain tumor patients use homeopathy, alternative treatments

A study published in Neurology found that nearly 40% of brain tumor patients use alternative therapies, including homeopathic remedies and vitamin supplements. Younger people, women, and those with more education were more likely to use these treatments, which they often sought to add benefits to conventional care.

New biological models of homeopathy published in special issues
