Dandelions are the nemesis of many a home gardener, but the annoying weed actually packs a nutritional punch. The leaves of the plant are rich in vitamins A, C and D as well as the B vitamins, according to the New York University Langone Medical Center. Certain chemicals in the plant also may be beneficial in medicinal applications.

Because of potential risks associated with its use, always consult with a medical profession before using dandelion root to improve your health.
Physical Description
Dandelions are a hardy perennial weed that produce a bright, yellow flower. The flowers, which can reach 1 foot tall, are sensitive to light and typically open in the morning and then close in the dark or in dreary conditions. The roots are filled with a milky substance that is bitter to the taste, according to the University of Maryland Medical Center. Hundreds of dandelion species exist, growing and thriving in the temperate parts of North America, Europe and Asia.
Medicinal Uses
The leaves and the roots of the dandelion plant are both used medicinally, but for different purposes. The roots of the plant have historically been used to treat liver disease, gallbladder problems, water retention, skin conditions, digestive conditions, breast conditions, joint pain and fever, according to New York University Langone Medical Center. Despite its long-held medicinal applications, no studies have conclusively proven it an effective herbal remedy.
