Bolboschoenus yagara is a species of flowering plant in the sedge family Cyperaceae. It is a perennial clonal herb, 0.8 to 1.3 meters tall, and develops underground rhizomes that terminate in spherical or ellipsoid tubers that are up to 3-4 centimeters in diameter.[1] It is able to propagate asexually through the tubers, as well as sexually by seeds.[2]
Classification
Bolboschoenus yagara is predominantly found in China and East Asia, with a fossilized specimen dated from the
It is possible that species that could not be clearly identified as either Bolboschoenus yagara or Bolboschoenus maritimus was in fact a B. yagara x B. maritimus hybrid.[4]
Habitat
Bolboschoenus yagara is found in wetlands, swamps, and other wet habitats. Unlike B. maritimus, Bolboschoenus yagara is a
It is found in littoral habitats on mineral-poor grounds; in Europe its populations are concentrated in several pond basins in Central Europe, with limited frequency in other regions. As a result of this limited range, it is at risk in Europe because of intensive fish pond management. The range of Bolboschoenus yagara overlaps with that of Bolboschoenus planiculmis.[7]
Like Bolboschoenus planiculmis, Bolboschoenus yagara is an important part of the migratory habitat for the
Uses
Bolboschoenus yagara tubers, known as jing sanleng (Mandarin: 荊三稜), are used in traditional Chinese medicine to treat a number of ailments such as hyperemesis gravidarum, amenorrhea, and inflammatory-related conditions.[9] Previous studies have identified a number of metabolites from the tubers of Bolboschoenus yagara that are theorized to have anti-inflammatory, anti-oxidant, and other properties, although these claims are speculative and their effectiveness has not been demonstrated in humans.[10]
