Research on therapeutic value of blackcurrants

Updated at 5:39 pm on 30 July 2010

Research in New Zealand and overseas is increasingly backing claims about the therapeutic qualities of blackcurrants.

Scientists in New Zealand, Japan, France and Scotland are investigating potential benefits that range from improving eyesight focus and night vision, to helping blood circulation and mental ability.

International Blackcurrant Association president Jim Grierson, of Christchurch, says human trials are starting to firm up some of that research.

He says the aim is to process more of the world blackcurrant production into higher-earning therapeutic products.

Most of the 270,000 tonnes grown each year in 19 countries is used in fruit drinks. Russia accounts for about 70% of world production.
