Cleavers

Christopher Hobbs:

“Cleavers is a mild diuretic and blood and lymphatic cleanser that is indicated for psoriasis and other skin conditions. It has a particular affinity for the lymphatic system and may be used for swollen glands, tonsillitis, and as a lymph tonic. Cleavers can be an effective herbal diuretic to clear bladder infections, cleanse the urinary tract, and help prevent small kidney stones from forming. In Chinese medicine cleavers are used to disperse stagnancy and inflammation and for urinary problems. Cleavers make a useful addition to formulas to lower blood pressure.

Cleavers has a taste of BITTER, ACRID and a temperature of COOL.”

Historical Uses

Historically, cleavers was used as a diuretic, aiding in urinary health and believed to cleanse the lymphatic system. Native Americans and European herbalists used it to treat conditions like bladder infections, skin conditions (like psoriasis and eczema), and respiratory ailments. Its ability to bind to surfaces (“cleave”) led people to use it for lymphatic congestion, skin wounds, and as a topical poultice.

Modern Clinical Uses

Today, cleavers is utilized by herbalists and naturopaths for lymphatic support, detoxification, and to reduce swelling. Its diuretic properties make it a common herb for urinary tract infections, and it’s also used in formulas for skin health and liver support. It is often combined with other herbs like dandelion, nettle, or calendula for synergistic effects.

Chemistry and Pharmacology

Cleavers contains iridoid glycosides (like asperuloside), tannins, flavonoids, and coumarins, which contribute to its anti-inflammatory, diuretic, and mild astringent properties. The plant’s fresh juice or infusion is often more potent, as some of its active constituents may degrade when dried. Studies indicate that its active compounds may promote lymphatic drainage and diuresis.

Clinical Trials

Few clinical trials have been conducted on cleavers, though preliminary studies suggest its efficacy as a mild diuretic. Most evidence remains anecdotal or based on traditional use, though some in vitro studies indicate promising lymphatic and anti-inflammatory activity.

Summary

Cleavers has a long-standing place in herbal medicine for lymphatic, urinary, and skin health, with some supportive pharmacological studies but limited clinical trials. Its safety profile is good when used in traditional dosages, making it a popular choice among herbalists for detox and supportive treatments.
