Cleavers are multi - branched, trailing or climbing herbaceous, in the elevation of 20-4600 meters of the hillside, wilderness, ditch, beach, field, forest margin, grassland. About 300 species worldwide occur in wet woodlands, marshes, river banks and coastal areas. Cleavers are a malignant weed in the field of summer ripe dry crops, and also have the function of antihypertensive and anti-cancer.
Cleavers are multi-branched, trailing or climbing herbs, usually 30-90 cm tall; Stem is 4-angled; There are inverted spines on edges, leaf margins and veins. Leaves are papery or submembranous, 6-8 whorled, rare to 4-5, banded oblanceolate or oblong-oblanceolate, 1-5.5 cm long and 1-7 mm wide, apical with needle-like convex heads, base tapering, often closely spiny hairs on both surfaces, often flaccid, stem often curled, 1-veined, subsessile. Cymes of Cleavers are axillary or terminal, few to many flowered, flowers small, 4-numbered, with slender pedicels; Calyx is hooked, calyx eaves subtruncate; Corolla is yellow-green or white, radiate, lobes oblong, less than 1 mm long, valvate; Ovary of Cleavers is hairy, style 2-lobed to middle, stigma capitate. Fruit is dry, with 1 or 2 subglobose mericarps, up to 5.5 mm in diam., swollen, densely hirsute, pedicel straight, up to 2.5 cm long, thick, each mericarp with 1 plane-convex seed.
Cleavers have lobed, often needle-like leaves with 4 to 8 whorls. Flowers are small, tufted, green, yellow, or white. Fruit is hard, round, two united. Northern Cleavers(G. Boreale), Bog Cleavers(G. Palustre) and Goose Cleavers(G. Aparine) were found throughout Europe and naturalized in some parts of North America. Cleavers(G. Odoratum or Asperula Odorata) have the smell of freshly cut hay. When the young ground is dried, Cleavers can be used for spices, sachets and drink flavorings. Yellow Cleavers(G. verum) were used in Europe to curdle milk and color cheese. The root tubers of several species of the genus can be used to make red dyes.
Cleavers is a small herb of Rubiaceae, belonging to dicotyledons. The tender shoots can be used as vegetables, it is said that pigs eat the disease, so it was named Cleavers.
Cleavers were born on hillsides, open fields, gullies, river banks, fields, forest margins and grasslands 20-4600 meters above sea level.

Cleavers distribute as far north as Liaoning, south to Guangdong, Guangxi. It is a malignant weed in the field of summer ripe dry crops.
In North China, Northwest China and the Huaihe River Basin, the damage to wheat and rapeseed occurred in a large area. In the south of the Yangtze River Basin, the damage to wheat and rapeseed was limited to mountain slopes, and the damage to wheat and rapeseed was greater than that to rapeseed. Climbing plants not only compete for sunlight and space with crops, but also cause crop lodging, resulting in greater yield reduction and affecting crop harvesting.
Wheat field control with the herbicide, such as paracarpus, giant star, broadgrass clear; Rape field with dry grass Ling, Wo Nai Si, GaoTeKe and other herbicides.
Cleavers has lengthy been used as a slimming aid, possibly due to the fact of its diuretic properties. Worldwide, cleavers most frequent use has been as a cleaning herb for treating illnesses from kidney and urinary problems to infections and itching.
