Uses

Toxic parts

The leaves contain oxalic acid, which gives them their sharp flavour. Perfectly all right in small quantities, the leaves should not be eaten in large amounts since oxalic acid can bind up the body's supply of calcium leading to nutritional deficiency. The quantity of oxalic acid will be reduced if the leaves are 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

Leaves - raw or cooked[2][3][4]. A mass of the leaves and stems can be allowed to ferment slightly when they make a tasty dessert[3]. A sort of rhubarb pie can be made from the leaf stalks[3]. Use in moderation, see notes above on toxicity.

Leaves

Unknown use

Material uses

A good ground cover plant for a woodland garden[5][6], though it can be invasive[7]. It needs weeding for the first year or so[5].
There are no material uses listed for Oxalis oregana.

Medicinal uses(Warning!)

A decoction of the whole plant has been used as a wash in the treatment of rheumatism[4].

The fresh juice of the plant has been used as eye drops to ease sore eyes[4].

A poultice of the wilted leaves has been used as a dressing on boils, sores and on swollen areas of the skin[4].

Propagation

Seed - best sown as soon as ripe in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle and plant them out in late spring or early summer. Division in spring. Larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.
