Traditional use
The tonka bean is the seed of Dipteryx odorata, a large tree of northern South America known as cumaru in Brazil. It is rich in coumarin, which gives it a scent reminiscent of vanilla and freshly mown hay; coumarin was in fact first isolated in 1820 from the tonka bean (Saragih et al. 2026).
The seed is collected and traded by Amazonian gatherers, notably for its coumarin, widely used in perfumery and cosmetics as a fixative (Sousa et al. 2022).
| Known compounds | Coumarin, present at relatively high levels and responsible for the scent (BfR); the seed also contains 30 to 40% of a fragrant oil (Sousa et al. 2022). |
|---|---|
| Traditional use | Seed gathered in Amazonia and traded, notably for perfumery. |
| State of research | The liver toxicity of coumarin is well documented (BfR). No health claim is authorised for the tonka bean in the EU. |
Good to know
- Coumarin can damage the liver in sensitive people; EFSA has set a tolerable daily intake (BfR).
- In the United States, food containing added coumarin, including as tonka bean, has been deemed adulterated since 1954 (21 CFR 189.130); in the EU, Regulation 1334/2008 sets maximum coumarin levels in certain foods.
The tree and its range
The tree was first named Coumarouna odorata by Aublet; today GBIF and the Kew checklist (WCVP) accept the name Dipteryx odorata (Aubl.) Forsyth f. The Kew checklist records the species as native to northern and west-central Brazil, French Guiana, Guyana, Suriname and Venezuela. Its Portuguese names include cumaru and cumbaru; English speakers know the seeds as tonka beans, French speakers as fève tonka.
How the seeds look
The photos show a clay bowl heaped with elongated, wrinkled seeds, dark brown to black. The supplier describes tonka beans as oval-shaped, dark brown and wrinkled. The same species also gives the Brazilian cumaru bark ash in the shop, made from the bark rather than the seed.
Storing your botanicals
Keep dried plants in their tightly closed pouch or in an airtight jar, away from light, moisture and heat. Powders absorb moisture easily, so close them again straight away. For extracts, tinctures and capsules, follow the instructions on the label and the printed date.
Before using a plant
- Keep plants out of the reach of children and pets.
- If you are pregnant or breastfeeding, or taking any medication, ask a doctor or pharmacist first: many plants interact with medicines.
- Stop immediately if you have an allergic reaction or feel unwell.
- The information on this page describes the product; it does not replace medical advice.
