Note: Other Galium species, such as Galium spurium L. (False cleavers), will not be discussed in this monograph.
Cleavers (Galium aparine) is a climbing plant native to North America, Europe, and Asia. It has been used to coagulate milk. According to some herbalists, cleavers is a good lymphatic and blood purifying tonic and is often used to treat swollen glands and skin eruptions caused by lymphatic congestion. It has also been recommended as a diuretic for chronic cystitis (inflamed bladder) and prostatitis (enlarged prostate), and has been used traditionally as a treatment for epilepsy. Currently, there is insufficient evidence in humans to support the use of cleavers for any indication.
These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
*Key to grades:
A: Strong scientific evidence for this use;
B: Good scientific evidence for this use;
C: Unclear scientific evidence for this use;
D: Fair scientific evidence against this use (it may not work);
F: Strong scientific evidence against this use (it likely does not work).
The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below. Antihypertensive, anti-inflammatory, antiperspirant, antipyretic, astringent, benign prostatic hypertrophy, blisters, blood cleanser, breast pain/inflammation, cancer , choleretic, chronic prostatitis, common cold, cystitis, dandruff, deodorant, detoxification, diarrhea, diuretic, earache, edema, enuresis, epilepsy, gallbladder stones, gout, hepatitis, hormonal effects, hysteria, immunomodulator, insect bites and stings (poisonous), insomnia, kidney cleanser, kidney stones, laxative, lymphadenitis, mastitis (animals), menopause, psychological disorders, relaxation/stress/anxiety, restlessness, scurvy, skin eruptions, stomach ailments, sunburn, swollen glands, tonsillitis, ulcers, urinary disorders, withdrawal from narcotics, wound healing.
The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.
Adults (18 years and older)
Although not well-studied in humans, a version of the red clover combination tea modeled after the Hoxsey formula that contains equal parts red clover, burdock, dandelion root, sarsaparilla, Oregon grape, cleavers, buckthorn, poke, echinacea, licorice, ginger, and wild yam (1 tablespoon of the herbal combination simmered in a cup of boiling water for 10 minutes) has been used at a dosage of 1/2 cup every 1-2 hours for one week.
Secondary sources claim that medium-strength doses of cleavers formulated using 2-4g of the dried herb, 2-4mL of a 1:1 25% fluid extract, or 4-10mL of a 5:1 25% tincture, may be taken three times a day.
Traditional practitioners have recommended that a tea made from the cleavers plant may be used internally and externally for the treatment of cancer. Other secondary sources claim that the juice of the plant may be more useful than a tea. There is insufficient evidence in humans, however, to support the use of cleavers for any indication.
Children (younger than 18 years)
There is no proven safe or effective dose for cleavers in children.
The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.
Avoid in individuals with a known allergy or hypersensitivity to cleavers (Galium aparine), its constituents, or members of the Rubiaceae family.
Side Effects and Warnings
There is insufficient evidence in humans to support the use of cleavers for any indication, as well as a lack of safety information. Cleavers has traditionally been used as a diuretic and caution is advised in patients taking diuretics or with urinary or renal (kidney) disorders.
Pregnancy and Breastfeeding
Cleavers is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.
Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.
Interactions with Drugs
Although not well studied in humans, cleavers may have diuretic, anti-inflammatory, antigout, antineoplastic, laxative, and hormonal properties. Caution is advised when taking cleavers with other agents that have these effects.
Interactions with Herbs and Dietary Supplements
Although not well studied in humans, cleavers may have diuretic, anti-inflammatory, antigout, antineoplastic, laxative, and hormonal properties. Caution is advised when taking cleavers with other herbs or supplements that have these effects.
