Galium odoratum, commonly known as sweet woodruff, is a perennial herb native to Europe and parts of Asia. It typically grows in shaded, moist woodlands and features whorled leaves and small white flowers that bloom in spring. The plant has a sweet, hay-like fragrance, which is most potent when dried. Sweet woodruff is often used in traditional herbal medicine and as a flavoring in beverages, particularly in German May wine. It contains coumarin, a compound that contributes to its aroma and potential health benefits. However, it should be used cautiously, as excessive consumption can be harmful.
