Until 2011, Dr. Edzard Ernst was the head of one of the few university departments doing real, unbiased research on the effectiveness and safety of alternative medicine techniques. That's important, because you can't just dismiss weird-sounding stuff out of hand, but you also want somebody other than the practitioners of that weird-sounding stuff conducting research and analyzing the data. Now retired, Ernst recently started blogging, and I wanted to point you to his new home on the Internet. He can be a bit snarky and caustic (especially with chiropractic and homeopathy). But in general he's a fair, reasonable, and knowledgeable source on what works and what doesn't. Definitely worth a bookmark.
