Benefits of blackcurrant

Blackcurrant leaves are mainly used for their diuretic property. A tea made from dried blackcurrant leaves is used against arthritis, urinary problems, diarrhoea, bleeding gums and coughs. Kessler T et al of the University of Bonn found that blackcurrant juice could support the treatment and metaphylaxis of uric acid stone disease because of its alkalizing effect. Blackcurrant juice increased the urinary pH level and the excretion of citric acid.

Syrup made from blackcurrant juice is often used to treat sore throats. The anthocyanidins in the blackcurrant berries are responsible for their antioxidant and antibacterial action.

Other facts

The blackcurrant originates from central and eastern Europe. Blackcurrant is now grown in all regions with cold and mild climates. Blackcurrants are widely used in the drinks industry. In some countries such as the United Kingdom, the Netherlands and France blackberry drinks are very popular. These blackberry drinks are promoted for their high vitamin C content.
