A relatively new site called rVita provides what looks like a fair evaluation of CAM. Subtitled "trusted information, natural healing", the site offers information on a broad range of topics organized by symptoms and treatments and rates the medical evidence for each. For instance, the page on green tea, the ever popular treatment with many claims to its name, reports that for everything from reducing cholesterol and treating diabetes that the evidence is unclear or conflicting. For each such treatment there are comments from blogs, reviews and links.
Most importantly, there is a page on How the scientific evidence is derived which includes ratings from strong evidence (randomized controlled clinical trials) to no evidence.
The site is well designed and also offers a trusted practitioner network and a sign up to be a blogger.
