Dandelion benefits all functions of the liver. It clears obstructions (such as stones) and detoxifies poisons that gather in the liver, spleen, and gallbladder. It will also promote healthy circulation. The juice from a broken leaf stem can be applied to warts and allowed to dry; used for 3 days or so it will dry up the warts. It is also used to treat premenstrual syndrome, as it is a diuretic. It has been shown to reduce cholesterol and uric acid. Dandelion also helps clear skin eruptions when used both internally and externally. It is a rich source of potassium, and contains more vitamin A than carrots.
