I knew from prior research that FTY720 was derived from a fungus that has been used for centuries in ancient Chinese medicine, but today I actually stumbled across an image of the fungus. Thought it would pique your curiosity to share it with you:
It's not much to look at and truth be told, I am so glad they figured out how to encapsulate the good stuff and put it in tiny pill form. I would hate to try to gag one of those down every morning with my decaf. Ewww. Actually, to be more accurate, they figured out how to synthetically reproduce it, so I don't think there's a laboratory growing fungus somewhere to keep all us trial patients supplied with pills.
An interesting read is found on the page I got the image from:
