There is a definite lack of good scientific studies on the value of dandelions. However, they are popular with herbalists as both a food and as herbal remedies. According to a University of Maryland Medical Center website (link found at the end of this paragraph), dandelions are a good source of vitamins A, B Complex, C, and D, as well as minerals Zinc, Potassium, and Iron. Historically the dandelion has been used for to treat liver ailments, as well as other issues. The leaves when consumed are believed to act as a diuretic, stimulating appetite and aiding digestion. The flowers are often attributed with antioxidant properties. The roots are used to cleanse the liver, gall-bladder, and kidney. http://www.umm.edu/altmed/articles/dandelion-000236.htm#axzz2SFBijkzS

Nathan dried the roots, then ground them and brewed them into Dandelion Root tea. The "tea" tasted a lot like coffee, which of course was good for him since he loves coffee. He also dried some of the leaves and blooms. I think he plans on combining these with ground root and a few other things to make another kind of Dandelion Tea.
As for the blooms...since we aren't wine drinkers we probably won't attempt to make Dandelion wine. We did, however, make an attempt at Dandelion Jelly. Picking all the fluffy little yellow flower petals out to use for the jelly is the most time consuming part. You soak the petals overnight in boiling water, then strain off the fluff. Stir in some pectin, add sugar, bring to a boil, then seal into jelly jars. We didn't have much luck getting the jelly to set on the first batch. It turned out to be a lovely yellow color, but closer to the consistency of honey then of jelly. It still tastes good, and so we have been using it like honey. We will, however, be making it again to try to get the jelly to set the next time around.

So those are our Dandelion adventures. If you're interested in recipes let me know. Nathan wants to try out eating some other wild plants that grow in Kansas, so stay tuned for future food adventures!
