on the leaves of cleavers, causing it to have a sticky feeling and giving it its name. The
leaves and flowers of cleavers are used medicinally.

diuretic.1 It was therefore used to relieve edema and to promote urine formation during bladder
infections. It has also been used by people with lymph swellings, jaundice, and wounds.
Active constituents
Galiosin, an anthraquinone glycoside, other glycosides, tannins, and flavonoids may be the major constituents of cleavers.
Little research has been conducted on this plant, but preliminary lab experiments suggest it
may have antispasmodic activity.2
How much is usually taken?
Cleavers tincture and tea are most widely recommended by herbal practitioners. Tincture
(1/2–1 teaspoon or 3–5 ml) can be taken three times per day. Tea is made by
steeping 2–3 teaspoons (10–15 grams) of the herb in 1 cup (250 ml) of hot water
for ten to fifteen minutes. People can drink three or more cups per day.

Cleavers has no known side effects and is thought to be safe for use by children and pregnant or nursing women.
