What is Giant knotweed?

Fallopia japonica, commonly known as Japanese knotweed, is a large, herbaceous perennial plant of the family 

Polygonaceae, native to Eastern Asia in Japan, China and Korea. In North America and Europe the species is 

very successful and has been classified as an invasive species in several countries. Japanese knotweed has 

hollow stems with distinct raised nodesthat give it the appearance of bamboo, though it is not closely related. 

While stems may reach a maximum height of 3–4 m each growing season, it is typical to see much smaller 

plants in places where they sprout through cracks in the pavement or are repeatedly cut down. The leaves 

are broad oval with a truncated base, 7–14 cm long and 5–12 cm broad, with an entire margin. The flowers 

are small, cream or white, produced in erect racemes 6–15 cm long in late summer and early autumn.

Closely related species include giant knotweed (Fallopia sachalinensis, syn.Polygonum sachalinense) and 

Russian vine (Fallopia baldschuanica, syn.Polygonum aubertii, Polygonum baldschuanicum).

Resveratrol

Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a stilbenoid, a type of natural phenol, and a phytoalexin produced 

naturally by several plants in response to injury or when the plant is under attack by pathogens such as bacteria 

or fungi. Food sources of resveratrol include the skin of grapes, blueberries, raspberries, mulberries and Fallopia 

japonica.

Resveratrol is naturally occurring phytoalexin produced by some higher plants in response to injury or fungal in 

fection. Phytoalexins are chemical substances produced by plants as a defense against in faction by pathogenic 

microorganisms, such as fungi. Alexin is from the Greek, meaning to ward off or to protect. Resveratrol may also 

have alexin-like activity for humans. Epidemiological, in vitro and animal studies suggest that a high resveratrol 

intake is associated with a reduced incidence of cardiovascular disease, and a reduced risk for cancer.
