Herbal Actions

Cleavers are traditionally associated with the following actions:

• Lymphatic support – encourages movement of lymph and interstitial fluids
• Alterative – supports gradual cleansing and metabolic balance
• Diuretic – gently supports urinary elimination
• Anti-inflammatory – helps calm low-grade tissue irritation
• Cooling – traditionally used where heat or congestion is present

These actions describe traditional functional use rather than medical treatment.

Practical Uses

In Western herbal practice, cleavers are most often used fresh and over time, particularly for lymphatic congestion, skin eruptions, and fluid stagnation. Herbalists value cleavers for their subtlety and safety, especially when long-term, gentle movement is needed rather than strong stimulation.

Product Forms

Cleavers are available in several preparations:

• Fresh herb tinctures – traditionally preferred for full activity
• Dried herb – used for teas, though milder than fresh
• Liquid extracts – alcohol or glycerin-based
• Capsules – powdered herb, less common
• Topical washes or compresses – for localized support

Fresh preparations are generally considered the most effective in traditional practice.

Traditional Herbal Recipes

1. Fresh Cleavers Tincture
   Prepared from freshly harvested aerial parts for lymphatic support.
2. Cleavers Cold Infusion
   Fresh or dried herb steeped in cool water to preserve delicate constituents.
3. Spring Cleansing Tea
   Cleavers blended with other gentle alteratives for seasonal use.
4. Topical Cleavers Wash
   Used externally for localized congestion or irritation.

Parts Used

• Aerial parts (leaves, stems, flowers), preferably fresh

Usage Forms & Shelf Life

Internal vs external use:
Used both internally and externally.

Common preparations:
Fresh tinctures, infusions, capsules, topical washes

Shelf-life ranges:

• Dried herb: 1–2 years
• Tinctures: 3–5 years
• Fresh preparations: used immediately or preserved as tincture

Safety & Considerations and Dosage Guidelines

Cleavers are traditionally considered very gentle and well suited for longer-term use. Herbalists often emphasize freshness and consistency rather than high doses. Because of their mild nature, cleavers are frequently combined with other herbs for broader effect.

Side Effects & Contraindications

Cleavers are generally well tolerated. Due to their diuretic nature, increased urination may be noticed. Adverse reactions are uncommon when used traditionally.

Active Constituents

Iridoid Glycosides

• Compounds: asperuloside
• Traditional role: associated with lymphatic and alterative actions
• Best extraction: fresh plant tinctures and gentle infusions
• Quantitative data: iridoids are present in small but active amounts typical of lymphatic herbs
  National Center for Biotechnology Information

Flavonoids

• Compounds: quercetin derivatives
• Traditional role: antioxidant and anti-inflammatory support
• Best extraction: water and alcohol

Tannins

• Traditional role: mild astringent support for tissues
• Best extraction: water-based preparations

How It Works

Traditionally, cleavers are understood to work by encouraging steady lymphatic movement and improving fluid circulation, helping tissues clear congestion gradually. Modern research supports their anti-inflammatory and diuretic properties, aligning with long-standing use for lymphatic and skin support

Processing Cautions

Cleavers lose activity quickly when dried. Gentle handling and fresh extraction are traditionally preferred. High heat is avoided to preserve delicate constituents.

Quick Herb Overview

• Botanical family: Rubiaceae
• Parts used: Aerial parts
• Energetics: Cooling, moistening
• Taste profile: Mild, green, slightly bitter

Herb Identification

Visual traits:
Long, scrambling stems with whorled narrow leaves and tiny hooked hairs that cling to clothing.

Growth habit:
Annual trailing plant that spreads readily in hedgerows and fields.

Look-alikes and safety notes:
Distinctive clingy texture makes identification straightforward.

Selecting Quality Herb

Choose vibrant green, freshly harvested cleavers whenever possible. Dried herb should retain color and mild aroma. Products should clearly state Galium aparine and plant part used.

Natural Growing Areas

Native to Europe and Asia; widely naturalized across North America in moist soils, fields, and woodland edges.

Growing Tips

Cleavers thrive in cool, moist conditions and often volunteer readily. Harvest young plants in spring before flowering for best quality.
