Kidney and urinary function
The French name for dandelion translates as bed-wetter, and the plant has a long folk reputation as a diuretic. One very small uncontrolled study of a leaf extract measured urine output; that is the entire human evidence base, and it says nothing about kidney function.
Insufficient evidence. Not enough human research to say anything useful yet.
