Caption: Coumarin (C9H6O2) crystals, polarised light micrograph. Formerly known as coumaine, this chemical is present in tonka beans, strawberries, cherries and liquorice. It has an odour of fresh hay and is used in perfume production. Coumarin was used as an additive in tobacco up until 1997 when it was banned in cigarettes, but is still used in pipe tobacco. The drug warfarin is a synthetic derivative of coumarin used to decrease blood coagulation by interfering with vitamin K metabolism. Magnification: x27 at 10cm wide.
