Historical or traditional use (may or may not be supported by scientific studies): Cleavers is one of numerous plants considered in ancient times to act as a 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.
Are there any side effects or interactions? Cleavers has no known side effects and is thought to be safe for use by children and pregnant or nursing women.
Are there any drug interactions? Certain medications may interact with cleavers. Refer to the drug interactions safety check for a list of those medications.
