The link TessLouise gave is invalid now - you get routed to Dr. Weil's home page and I couldn't find the recipe. I imagine it's there somewhere, but I couldn't locate it. I looked around on the Internet and found places where it had been reproduced in other Websites. Looking at those, I figure this is how Dr. Weil's original recipe looked. If anyone actually made a copy when the link was active and has a different version, please post it.
