There is a growing health scare in Japan after two more fatalities have been linked to a popular dietary supplement, bringing the death toll to four. The tablets in question are made by Kobayashi Pharmaceutical, one of Japan's top drugmakers. They contain an ingredient called red yeast rice, or "beni koji" which is supposed to help lower cholesterol. More than 100 other people who took the supplement have been hospitalised.
