## At a glance

Tonka beans are the seeds of the South American Dipteryx odorata tree. Their scent comes from coumarin, 1–3% of their weight. Because high amounts of coumarin can damage the liver, adding it to food is banned in the US and limited in Europe. Claims that tonka is an aphrodisiac or calming are unproven.

**Parts used:** seeds

**Key constituents:** Coumarin (1–3%)
