Dandelion is a very rich source of beta-carotene which we convert into vitamin A. This flowering plant is also rich in vitamin C, fiber, potassium, iron, calcium, magnesium, zinc, and phosphorus. It’s a good place to get B complex vitamins, trace minerals, organic sodium, and even some vitamin D too. Dandelion also contains protein, more than spinach. It has been eaten for thousands of years as a food and as a medicine to treat anemia, scurvy, skin problems, blood disorders, and depression.
