Persicaria sagittata

(L.) H.Gross

Polygonaceae


Persicaria sagittata is an extremely variable species and is known from distinct populations in both Asia and North America. They have been treated as distinct in the past (the Asia form being treated as Persicaria sieboldii). Recent molecular analyses of North American and eastern Asian populations show that these disjunct populations are genetically somewhat divergent from each other. The degree of genetic divergence, however, strongly suggests that they can be recognized either as a single polymorphic species (Persicaria sagittata) or two distinct varieties of Persicaria sagittata, but they can hardly be treated as two distinct species[

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[
