Coumarin is a fragrant organic compound found in many plants, particularly in tonka beans, cinnamon, and sweet clover. It has a sweet, vanilla-like aroma and is often used in perfumes and flavorings. Coumarin is also studied for its potential medicinal properties, including anti-inflammatory and anticoagulant effects. In addition to its use in cosmetics and food, coumarin is important in the field of chemistry. It serves as a building block for synthesizing various pharmaceuticals and other chemical compounds. However, high concentrations of coumarin can be toxic, leading to regulations on its use in food products in some countries.
