One of the common claims of alternative medicine practitioners is that they individualize their treatment while conventional medicine treats all patients the same. This is nonsense on several levels, but it is also a common excuse for why randomized clinical trials cannot be performed, or cannot be viewed as reliable evidence, in evaluating some alternative therapies. However, some trials have been done that attempt to account for this supposed individualization of therapy, and generally they have failed to show a benefit to the supposedly individualized approach. One of those, involving Traditional Chinese Medicine (TCM) was recently discussed by Edzard Ernst, one of few, and most productive researchers in the CAM field applying an evidence-based approach:
