Common Name: Yellow Wood Sorrel
Oxalis stricta is an annual plant that can grow up to 30cm tall
The plant is harvested from the wild for local use as a food, medicine and source of materials.
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[
Widely naturalized from the temperate zone to the tropics, it is a cosmopolitan weed originating probably inMesoamerica and northern S. America

A poultice of the plant has been used to treat swellings[
A yellow to orange dye can be obtained by boiling up the whole plant[
Seed - best sown as soon as it is ripe in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.
If you have enough seed it can be sown in situ during the spring.
