Cleavers is an herb. People use the parts that grow above the ground to make medicine.
Cleavers is used to increase urine flow to relieve fluid retention. It is also used for painful urination, enlarged or infected lymph nodes, and a skin condition called psoriasis.
People sometimes apply cleavers directly to the skin for ulcers, enlarged glands, breast lumps, and skin rashes.
Cleavers contains chemicals called tannins that might help reduce skin inflammation and have a drying (astringent) effect on the tissues.
