Ask a question


A naturally fragrant substance, coumarin is used in perfumery. Its odor approaches vanillin and freshly cut hay. It is found in several different plants such as asperula, Chinese cinnamon, celery, tonka beans, true lavender, etc. From a medical standpoint, coumarin was used as an anti-edematous because of its action on lymphatic drainage, which it facilitates. Nevertheless, it is no longer used due to the hepatic disorders it provoked.
