Herbal diet drug 'is heart risk'

Slimmers have been warned against using a popular herbal remedy to help them lose weight.
Doctors in the United States say Metabolife 356 can have a potentially lethal effect on the heart.

Writing in the Journal of the American Medical Association, doctors urged people to avoid taking the product until further research is carried out.

However, the manufacturers have rejected the claims saying studies show Metabolife 356 is safe to use.

David Cohen, national science counsel for Metabolife International, said: "Metabolife is very safe when used as recommended."
