Uses

Toxic parts

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[1].

Edible uses

Notes

Young leaves - cooked[2][3][4][5]. Used like spinach[6]. A bitter taste, the native North American Indians would add oil to improve the flavour[7].

Young stems - cooked[7]. Used like rhubarb[7].

Seed - raw or cooked[4][8][6]. The seed can also be ground into a powder and used to make a gruel or added to cereal flours when making bread etc. It is rather small and fiddly to harvest.

Leaves

Material uses
