Overview
Cleavers is the quintessential lymphatic herb of Western herbal medicine. Its sticky whorled leaves cling to clothing and animal fur — a feature that symbolizes its clinical action of 'attaching to' and clearing lymphatic congestion. Spring harvest cleavers is one of the premier lymphatic depuratives, used to decongest swollen lymph nodes, clear skin conditions associated with lymphatic stagnation, and as a spring detox tonic.
Traditional Use
Cleavers has been used as a spring tonic across European herbal traditions for centuries. In British and Irish traditional medicine, the fresh spring herb was squeezed for juice and consumed as a spring detox. Culpeper (1653) recommended it for 'cleansing the blood and strengthening the liver.' Native American tribes used related Galium species for similar lymphatic and skin-clearing purposes. Traditional use across Europe for swollen glands, skin conditions, and urinary complaints.

Common Preparation Methods
Fresh Juice (Best Form)

Cold Infusion of Fresh Herb
Stuff a jar with fresh cleavers, cover with cold water, leave overnight in refrigerator. Strain and drink.
Dosage: 1–2 cups dailyCold water preserves heat-sensitive constituents better than hot infusion. Another excellent method when fresh juicing equipment is unavailable.
