Harvesting Dandelions Those bright yellow weeds that seem to pop up overnight in own lawns are far more than just the weeds we commonly refer them to. Get ready to have your mind blown with some wonderful facts that I'm hoping will change your mind about the way you view this plant. Dandelions are far more nutritional than kale or spinach, they are packed full of vitamins and antioxidants that has super benefits to your body and your skin. Just half a cup of dandelion greens has more calcium than a glass of milk! Their greens are a fabulous source of vitamins C, A and K. Because dandelions are rich in potassium, this makes them a perfect diuretic and an excellent blood detoxifier. Now I know as a child we referred to them as "wet the beds". They are in fact, great for water retention because of their detoxifying properties. Is this why we called them "wet the beds" do you think???
