Medical researchers recently investigated homeopathic practices in Germany and Switzerland to understand the effect of homeopathic care on older patients.

Our findings might indicate that homeopathic medical therapy may play a beneficial role in the long-term care of older adults with chronic diseases and studies on comparative effectiveness are needed to evaluate this hypothesis."
