The common Dandelion (Taraxacum officinale) is known to most of us as a "weed", but has been used medicinally, as well as for food, for over 1000 years. Both the leaves and the root are used medicinally, and even the flowers are used to make wine. The constituents of dandelion include triterpenes (taraxerol, taraxasterol etc), sterols, inulin (25%), sugars, vitamins and other compounds. Dandelion leaves contain more vitamin A, by weight, than carrots.
Dandelion root and its extracts have been used extensively as a liver tonic, to promote bile, and through its liver "cleansing" actions, various skin conditions. The leaf portion is "Approved" by the German Commission E for loss of appetite and indigestion, while the root portion is "Approved" by the Commission E for disturbances of bile flow, as a diuretic and for indigestion.
Dandelion stimulates the flow of bile and is a liver and digestive tonic. Dandelion extracts are said to also benefit the spleen and improve the health of the pancreas. It is important to note that this herb has been shown to uniformly remedy chronic liver congestion, prevent liver cell death from many toxins and support hepatic regeneration.
