The adolescent stems are comestible as a bounce vegetable, with a acidity agnate to acutely acerb rhubarb. In some locations, semi-cultivating Japanese knotweed for aliment has been acclimated as a agency of authoritative knotweed populations that access acute wetland areas and drive out the built-in vegetation. Use in Japan as sansai or agrarian foraged vegetable is discussed beneath beneath.
Some attention should be acclimatized if arresting this bulb because it, agnate to rhubarb, contains oxalic acid, which may aggravate altitude such as rheumatism, arthritis, gout, branch stones or hyperacidity.

Polygonum cuspidatum abstract is a comestible supplement acquired from the Japanese knotweed. It contains the actinic resveratrol. It has abounding bloom benefits; for example, it strengthens the allowed arrangement and has antibacterial properties.
Polygonum cuspidatum has a ample underground arrangement of roots (rhizomes). To eradicate the bulb the roots charge to be killed. All above-ground portions of the bulb charge to be controlled again for several years in adjustment to abate and annihilate the absolute patch. Picking the appropriate herbicide is essential, as it have to biking through the bulb and into the basis arrangement below. Glyphosate is the best alive additive in herbicide for use on Japanese knotweed as it is ’systemic’; it penetrates through the accomplished bulb and campaign to the roots.
