The Surprising Link Between Cleavers and Coffee
It may seem unlikely, but the humble cleavers plant (Galium aparine), a common garden weed known for its clingy, Velcro-like stems, is a relative of the coffee plant. This botanical connection is the key to understanding its caffeine content. The similarities, however, are restricted to the seeds, not the entire plant, which is a critical detail for those using cleavers for traditional herbal remedies.
The Seeds: A Mildly Caffeinated Foraged Treat
For centuries, foragers have known that the seeds of the cleavers plant, or 'nutlets', can be used to make a coffee-like beverage. These small, burr-like seeds, which are covered in tiny hooks, are harvested, dried, roasted, and ground to brew a drink that mimics the flavor profile of coffee but with a much milder caffeine content. Harvesting enough seeds for a single cup can be time-consuming, as they don't all ripen at the same time and are quite small.
The Leaves and Stems: Your Caffeine-Free Herbal Ally
In contrast to the seeds, the green, leafy parts of the cleavers plant, which are traditionally used for making herbal tea, are naturally caffeine-free. This distinction is vital for those who consume cleavers tea for its gentle diuretic and lymphatic-cleansing properties, without wanting the stimulating effects of caffeine. As a spring tonic, cleavers tea helps clear waste and toxins from the body and supports the immune system.
Cleavers Tea Preparation
Preparing a traditional cleavers tea from the leaves and stems is a straightforward process. You will need:
- Fresh or dried cleavers leaves and stems
- Hot water (not boiling)
Instructions:
- Steep one to two teaspoons of the dried herb in eight ounces of hot water for 5-10 minutes.
- Alternatively, if using fresh cleavers, simply place a handful in a jar of water and let it sit for a few hours to create a 'succus' or fresh plant infusion.
A Comparison of Cleavers with Other Common Beverages
To clarify the difference, here is a breakdown of the caffeine content of different cleavers preparations versus standard beverages.
| Beverage | Primary Source | Caffeine Content | Stimulant Effects | Notes |
|---|---|---|---|---|
| Cleavers Seeds (Roasted) | Cleavers Seeds | Very Mild | Slight | Mild coffee-like flavor; foraging is labor-intensive. |
| Cleavers Tea (Leaves) | Cleavers Leaves/Stems | Caffeine-Free | None | Mild, earthy flavor; primarily used for diuretic effects. |
| Brewed Coffee | Coffee Beans | High | Strong | Made from roasted and ground beans of the coffee plant. |
| Green Tea | Tea Leaves | Moderate | Mild to Moderate | Made from the tea plant (Camellia sinensis); contains L-theanine. |
| Water | H2O | None | None | Essential for hydration, but no stimulant properties. |
Safety and Considerations for Cleavers Consumption
While cleavers are generally considered safe for most people, some individuals should be cautious. Pregnant women should consult a healthcare provider before consuming cleavers, as some traditional uses suggest it can stimulate contractions. Additionally, people taking blood-thinning medications should speak to a medical professional, and anyone with allergies should start with a small amount to test for a reaction. The herb's potent diuretic effect should also be noted.
Conclusion: Cleavers and Your Daily Brew
So, do cleavers contain caffeine? The short answer is yes, but only in its seeds and in very small quantities. For most people who use cleavers as a soothing, lymphatic herbal tea, the beverage is reliably caffeine-free. The dual nature of this versatile plant—one part a mild coffee alternative, the other a calming herbal tonic—highlights its unique place in the world of foraging and herbal medicine. This knowledge allows consumers to choose the right part of the plant for their specific health goals, whether seeking a detoxifying brew or a unique, low-caffeine coffee substitute.

How can I identify cleavers in the wild?
Cleavers is easily identifiable by its whorled leaves and its tiny, hooked hairs on the stems and seeds that cause it to stick to clothing. It is a sprawling annual herb often found in hedges and disturbed ground.
Are all parts of the cleavers plant edible?
