Cleavers (Galium aparine) is an herb found throughout Europe, North America, Asia, Greenland, and Australia.  It is described as an edible weed or a wildflower that appears in spring in untreated garden areas.  It is a fabulous addition to any salad or sandwich! It is "sticky" and can grow three feet tall on a trellis or will climb/spread over the ground or other nearby plants and beyond, adorned with small greenish-white flowers. 
 
Cleavers is one of numerous plants considered in ancient times to act as a diuretic. It was therefore used to relieve edema and to promote urine formation during bladder infections. It has also been used by people with lymph swellings, jaundice, and wounds. (https://www.peacehealth.org/medical-topics/id/hn-2070002)
 
Cleavers can enhance the function of the lymphatic system and improve its detox ability to flush out toxins, decrease congestion and reduce swelling. The lymph-cleansing action of this herb in turn enhances the function of the immune system.
 
Possible Side Effects: Cleavers isn't known to interact with any medications or other herbal supplements. As an edible plant, there appears to be minimal risk associated with ingesting cleavers or placing it on the skin. Although no notable side effects are associated with cleavers, an allergic reaction is always possible. (https://www.verywellhealth.com/cleavers-health-benefits-5084341)
