Cleavers ($Galium aparine$) is a common, annual climbing plant known for its sticky, velcro-like texture that causes it to cling to clothing and animal fur. While often dismissed as a persistent garden weed, this resourceful plant offers a wealth of uses, from culinary and medicinal applications to historical folk traditions. Its distinctive square stems, whorls of lance-shaped leaves, and clinging nature make it easy to identify for foragers.
Edible Uses of Cleavers
This abundant spring plant provides a free and nutritious food source. While the young shoots have a mild, grassy, or pea-like flavor, the older plant can become quite fibrous. Cooking helps to soften the bristly texture, making it more palatable.
Culinary Preparations:
- Blanched Greens: Treat young cleavers shoots like spinach. Blanch them briefly in boiling water to soften, then add to salads or serve as a side dish.
- Soups and Stews: The shoots add a mild, earthy flavor to soups and stews. They can be cooked down with other spring vegetables.
- Wild Green Smoothies: For a nutritious boost, blend fresh cleavers juice with water or fruit juice. Be sure to strain out the fibrous material for a smoother consistency.
- Roasted Seed Coffee Substitute: The seeds of the cleavers plant belong to the coffee family ($Rubiaceae$). When dried, roasted, and ground, they can be brewed to create a caffeine-free beverage with a coffee-like flavor.
Medicinal Preparations
Cleavers has a long history in traditional herbal medicine, prized for its diuretic and lymphatic-toning properties. It is believed to help the body's natural cleansing processes and support the immune system.
Internal Remedies:
- Herbal Infusion (Tea): A cold-water infusion is one of the most common and effective ways to use cleavers. Steep a handful of fresh cleavers in cold water for several hours or overnight to create a mild, cleansing tonic. It can be especially beneficial as a "spring tonic" to help detoxify after winter.
- Tinctures: To preserve the plant's medicinal properties for a longer period, a tincture can be made using fresh cleavers and alcohol.
- Juice: Juicing the fresh plant is a potent way to receive its benefits. The resulting green liquid can be drunk in small amounts or frozen into ice cubes for later use in smoothies.
- Vinegar Infusion: Infusing cleavers in apple cider vinegar creates a flavorful and medicinal vinegar that can be used in dressings or added to beverages.
Topical Applications:
- Poultice: A simple poultice can be made by crushing fresh cleavers leaves and applying them directly to minor wounds, rashes, burns, or insect bites to soothe inflammation and aid healing.
- Salve or Balm: Cleavers can be infused into oil, which is then used to create a salve for treating skin conditions like eczema or psoriasis.
Practical and Folk Applications
Beyond food and medicine, cleavers has several historical and practical uses that highlight its versatility and unique physical properties.
Historic Uses:
- Natural Strainer: The plant's bristly nature allowed it to be woven into temporary sieves, famously used by ancient Greeks to strain milk.
- Mattress Stuffing: Historically, dried and matted cleavers were used to stuff mattresses. The interlocking bristles helped the filling maintain its shape, leading to the common name "bedstraw".
- Natural Dye: The roots of the cleavers plant produce a reddish dye, used by natural crafters.

Harvesting and Sustainability
Harvesting cleavers should be done in the spring, just before the plant flowers, when the stems and leaves are most tender. Avoid harvesting near roadsides or areas with potential contamination. Only take what you need, ensuring the plant can still propagate. For more detailed harvesting advice, the resource from Unruly Gardening offers helpful tips.
Cautions and Considerations
While generally safe for most people, some individuals may experience a mild allergic reaction, including skin irritation. Cleavers has diuretic and potential anticoagulant effects, so it should be avoided by pregnant or nursing women, individuals on blood-thinning medication, and those with certain kidney conditions. Always consult a healthcare professional before incorporating any new herbal remedy into your routine.
