The tonka bean is the seed of "Dipteryx odorata", a legume tree in the neotropics, of the Fabaceae family. The seed is black and wrinkled in appearance, with a smooth brown interior. It is known mostly for its fragrance, which is reminiscent of vanilla, almonds, cinnamon, and cloves: it has sometimes been used commercially as a substitute for vanilla. It is also sometimes used in perfume and was commonly used in tobacco before being banned.

The seed contains coumarin, which can be lethal in large doses. For this reason its use in food is banned in the US by the Food and Drug Administration (FDA). Many anti-coagulant prescription drugs are based on more powerful forms of coumarin.

The plant has its origin in Northern South America (Guyana, Orinoco region). Main producers today are Venezuela and also Nigeria.
