Rumex daiwoo

Common name:		Family:	Polygonaceae
Author:	Makino.	Botanical references:	58
Synonyms:	Rumex madaio (Makino.)
Known Hazards:	Plants can contain quite high levels of oxalic acid, which is what gives the leaves of many members of this genus an acid-lemon flavour. Perfectly alright in small quantities, the leaves should not be eaten in large amounts since the oxalic acid can lock-up other nutrients in the food, especially calcium, thus causing mineral deficiencies. The oxalic acid content will be reduced if the plant is cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition[238].
Range:	E. Asia - Japan.
Habitat:	Wet meadows in lowland all over Japan[58].
Edibility Rating (1-5):	1	Medicinal Rating (1-5):	2

Systematics:	From a USDA Plants Database
	Order: Polygonales. Buckwheat family
Other Range Info:	From the Ethnobotany Database
	China
