The dandelion plant is a powerful healer, used to purify the blood, settle digestion and prevent piles and gall stones, among other maladies. The fact is the greens of the humble dandelion provide 535 percent of the recommended daily value of vitamin K, which may be the most important source of any other plant-based food to strengthen bones, but may also play a role in fighting Alzheimer's disease by limiting neuron damage in the brain. Dandelion greens also give the body 112 percent of the daily minimum requirement of vitamin A as an antioxidant carotenoid, which is particularly good for the skin, mucus membranes and vision. A flavonoid called zeaxanthin protects the retina from UV rays, while others, primarily carotene, lutein, and cryptoxanthin, protect the body from lung and mouth cancers. Need more benefits? Dandelion greens are high in fiber, which helps your body shed waste. These greens also contain vitamins C and B6, thiamin, riboflavin, calcium, iron (crucial for generating red blood cells), potassium (to help regulate heart rate and blood pressure), and manganese. Other nutrients present in dandelion greens include folate, magnesium, phosphorus, and copper.
I personally use dandelion root to shed water retention....you know... pizza the previous night!
