Coumarins are a class of organic compounds found in many plants, characterized by their sweet scent and flavor. They are often present in essential oils and are responsible for the fragrance of certain flowers and fruits. Coumarins have a variety of applications, including use in perfumes, flavorings, and traditional medicine. In addition to their aromatic properties, some coumarins possess biological activities, such as anticoagulant effects. For example, warfarin, a medication derived from coumarin, is commonly used to prevent blood clots. Research continues to explore the potential health benefits and uses of coumarins in various fields.
