Dandelion first appeared in the 10th century in Arabian medicine and has been used as a diuretic, a treatment for anemia, a blood tonic, a mild laxative, and an appetite stimulant. Europeans used dandelion to treat diabetes. It is reported that dandelion is more nutritious than spinach. It may have antiviral properties that help prevent herpes.
