}}Persicaria chinensis (synonym Polygonum chinense),[ commonly known as creeping smartweed[1] or Chinese knotweed, is a plant species from the family Polygonaceae.] It is widespread across China, Japan, the Indian Subcontinent, Indonesia, Malaysia, and Vietnam.[2] It is a common plant in Malaysia and Vietnam, where it is used in herbal remedies, such as for the treatment of dysentery, enteritis, and sore throat.[3] It is a weed in some coastal areas of New South Wales and Queensland in Australia.[4] Persicaria chinensis is a perennial climber that grows to 2–3 m high. Its stems are glabrous and red-brown, with longitudinal stripes. Its leaves have oval blades, are 4–8 cm long and 3–5 cm wide, with pointed apex and round or nearly cordate base. Its cymes emerge at terminals, and are 5–7 cm long, with small white or pink flowers.[3]References1. ^{{Cite book|url=http://www.forest.go.kr/kna/special/download/English_Names_for_Korean_Native_Plants.pdf|title=English Names for Korean Native Plants|publisher=Korea National Arboretum|year=2015|isbn=978-89-97450-98-5|location=Pocheon|pages=565|access-date=25 January 2016|via=Korea Forest Service|deadurl=yes|archiveurl=https://web.archive.org/web/20170525105020/http://www.forest.go.kr/kna/special/download/English_Names_for_Korean_Native_Plants.pdf|archivedate=25 May 2017|df=}}
