The tonka bean tree, scientifically known as *Dipteryx odorata*, is a tropical tree native to the Amazon rainforest and parts of Central America. It can grow up to 30 meters tall and produces small, fragrant flowers that develop into pods containing the tonka beans. These beans are dark brown and have a sweet, vanilla-like aroma. Tonka beans are often used in perfumery and culinary applications due to their unique scent, which is attributed to a compound called coumarin. In some regions, the beans are also used in traditional medicine. However, their use in food is restricted in some countries due to potential health concerns.
