As mentioned earlier, the seeds of Tonka bean enclose coumarin, a chemical isolated from this rainforest tree. Normally, the seeds of this plant enclose about 1 per cent to 3 per cent coumarin, and seldom it is found that the coumarin content of the seeds is as elevated as 10 per cent. The pleasing smell of the Tonka bean seeds is attributable to coumarin, which has some utility in the perfume industry. In fact, the flavour of coumarin is bitter and when taken in large doses in the form of an infusion, it may result in liver damage as well as hemorrhage. In addition, excessive dosage of Tonka bean seed infusion may also cause cardiac paralysis. Hence, many governments have restricted the use of coumarin or Tonka seed extracts in the form of a food additive. Similar to many other plants, even the Tonka bean tree possibly makes coumarin to protect itself.

The US Food and Drug Administration (FDA) considers any food containing tonka bean or tonka bean extract to be impure.
