FAQ

Frequently Asked Questions

No. Dicoumarin (or dicoumarol) is a natural compound. Warfarin is a later, synthetic derivative that is more potent and widely used as an anticoagulant medication.

It was the first oral anticoagulant discovered and its study directly led to the development of widely used drugs like warfarin, revolutionising the treatment of thromboembolic diseases.

Not typically in prepared foods. It forms naturally through microbial action in spoiled sweet clover and similar plants, making it a risk in poorly stored animal fodder, not human cuisine.

It is pronounced /daɪˈkuːmərɪn/ (dye-KOO-muh-rin), with a hard 'c' as in 'cougar'.

Memory Aids

Mnemonic

Think: DI (two) COUMARIN molecules linked together. DI for double, COUMARIN for the parent compound found in plants. It's a DOUBLE-TROUBLE anticoagulant (discovered from sick cattle).
