As I was flicking through the Which magazine, I came across this snipet that might be good for some Tumeric users to be aware of - there is a particular tumeric supplement marketed as Fortodol or Miradin which contains a strong anti-inflammatory drug which can cause serious damage to the liver.
The paragraph does not mention any other brand and just suggests to be careful. ‘Which’ is a respected UK magazine and they are likely to have researched this carefully before printing.
