Dandelions have a long history of medicinal use. The first written mention of this is in Arabian medical texts of the 10th and 11th centuries.
Dandelion is known for its diuretic properties. The French word for dandelion is pissenlit which means "pee in bed". Because of the plant's high potassium content, it doesn't have the potassium-depleting side effect that is common with many diuretic drugs.
Dandelion is highly esteemed as a remedy for liver problems. It is also recommended for treatment of urinary, kidney, and digestive disorders.
The white sap of the dandelion stem is believed to be healing to the skin.
