Dandelion is used for many conditions, but so far, there isn’t enough scientific evidence to determine whether or not it is effective for any of them.
Dandelion is used for loss of appetite, upset stomach, intestinal gas, gallstones, joint pain, muscle aches, eczema, and bruises. Dandelion is also used to increase urine production and as a laxative to increase bowel movements. It is also used as skin toner, blood tonic, and digestive tonic.
Some people use dandelion to treat infection, especially viral infections, and cancer.
