Scientists in India have developed a way to extract juice effectively for the first time from a berry which is thought to be good for the heart.
Sea buckthorn is a known source of cholesterol-lowering compounds which could prevent clogging of the arteries.
It is used in Tibet, Mongolia, China and Russia for health drinks.
But the researchers, writing in the Journal of the Science of Food and Agriculture, report current extraction methods produce juice of poor quality.
