Herbs - Plant Constituents - Coumarin & Glycosides

Used in the perfume industry for their "newly mown hay" aroma, coumarins have not been well studied. Recent research shows that they play a role as anti-clotting agents and are the basis of the anti-coagulant drug warfarin. Anti-bacterial action of Coumarin is the basis of the use of Mouse-eared Hawkweed. Umbelliferone is another example, found widely in the Umbelliferae family as well as Aesuetin in Rupturewort and Lavender.
