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]. Used as greens. Young stems - cooked[2][3][4]. Used like rhubarb[5].

Leaves

Stem

Unknown use

Material uses

A yellow dye is obtained from the root[6]. The roots are peeled, broken into sections about 25mm long, then spread out thinly in a sunny position until very dry. They are then soaked in water for a few days before being boiled in the same water for a long time. Alum is then added to fix the colour[5]. A red dye is obtained if ashes are added and it turns black if the bark of Cornus stolonifera is also added[6].

Medicinal uses(Warning!)

The root is astringent, blood purifier and tonic[5]. A decoction has been used in the treatment of diarrhoea, coughs and colds, influenza, pneumonia, stomach aches, kidney disorders, gall bladder problems, venereal disease and rheumatism[5]. An infusion has been given to women to help them expel the afterbirth[5]. The root can be dried, ground into a powder and used as a dressing on burns, wounds, sores etc[6][5]. A poultice can also be made from the fresh root for use on burns, wounds, sores, swellings etc[6][5]. An infusion of the stems and leaves has been used as a wash on sores[5].
