Persicaria kawagoeana

(Makino) Nakai

Polygonaceae


Some of the reports listed here were for Persicaria minor (Huds.) Opiz. However, Persicaria minor is restricted to temperate areas of Europe, eastern and northern Asia; whilst these reports were for plants in Malesia, New Guinea and Australia. Persicaria minor was originally recorded as occurring in these tropical areas, in the forms of the subspecies micranthum (Meisner) Danser; and procerum (Danser) Steward. However, these subspecies have now been transferred to Persicaria kawagoeana[

Known Hazards

Although no specific mention has been made for this species, there have been reports that some members of this genus can cause photosensitivity in susceptible people.
Many species also contain oxalic acid (the distinctive lemony flavour of sorrel) - whilst not toxic this substance can bind up other minerals making them unavailable to the body and leading to mineral deficiency. Having said that, a number of common foods such as sorrel and rhubarb contain oxalic acid and the leaves of most members of this genus are nutritious and beneficial to eat in moderate quantities. Cooking the leaves will reduce their content of oxalic acid. 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[
