FWIW, Red Yeast Rice is not a homeopathic cure. It appears to be a naturally occurring statin, though I don't know of any clinical trials for it.
My doctor (regular certified GP) recommended to try it. He said if it worked, keep doing it. Cholesterol measures before and after 30 days revealed about a 5% drop in LDL levels in my case, so I keep taking it. My Cholesterol rises each year I'm tested: it's clearly a genetic problem in my family. Red yeast rice bought me an extra couple of years before moving onto the stronger pharmaceutical stuff (Lipitor, etc.).
That said, taking up rowing and getting fit again reduced the levels by about 10% a couple of years later. Exercise worked better for me!
But don't confuse homeopathy with "natural" or "herbal" remedies.
