Cumaru, also known as tonka bean, is one of the Amazon rainforest’s most intriguing botanical gems. With its complex fragrance and powerful natural compounds, this seed has captivated industries ranging from perfumery and cosmetics to gourmet cuisine and traditional medicine.

In this article, you’ll discover:

• What cumaru is and where it comes from

• Curious facts and history

• The environmental importance of its sustainable harvesting

• And how the same natural inspiration translates into modern skincare rituals

What is Cumaru?

Cumaru is the seed of the Dipteryx odorata tree, a legume native to South America, especially the Amazon region. The seed, known as tonka bean, has a dark wrinkled shell and an incredibly rich, sweet aroma often compared to vanilla, almonds, cinnamon, and cloves—all at once.

This intense scent is due to a natural compound called coumarin, present in high concentration in the seed. Though coumarin is toxic in large amounts, in small doses it is considered safe and is widely used in perfumery and cosmetics.

Origins: From the Amazon to the World

The cumaru tree grows up to 30 meters high and produces fruit once or twice a year. When the pods fall to the ground, local collectors gather them manually, especially in the Brazilian states of Pará, Acre, and Amazonas. This traditional method supports sustainable forest management while providing income for rural communities.

What is Cumaru Used For?

Cumaru has a wide range of applications that stretch across industries and continents:

1. Perfumery

Tonka bean absolute is a favorite base note in luxury perfumes. Brands like Guerlain and Tom Ford use it to add depth and sensual warmth to their fragrances.

2. Gourmet Cooking

In some parts of Europe and Asia, grated tonka bean is used to flavor desserts, chocolates, and even cocktails. Its unique flavor, similar to vanilla with a twist of spice, is considered a delicacy. (Note: Its use in food is restricted in the U.S. due to coumarin regulations.)

3. Natural Cosmetics

Tonka bean extract is used in creams, body oils, soaps, and lotions. It offers a soothing aroma and potential antioxidant and anti-inflammatory properties.

4. Hardwood Timber

Cumaru wood is extremely dense and durable. It’s used to build decking, furniture, flooring, and even boats. It’s often referred to as “Brazilian Teak.”

5. Traditional Medicine

In folk medicine, cumaru is used in teas or infusions for respiratory issues and joint pain. Its coumarin content is believed to help reduce inflammation and improve circulation.

Cultural and Historical Facts

• Indigenous peoples used cumaru seeds as talismans for luck and protection.

• In the 1800s, cumaru began to replace vanilla in European bakeries due to supply issues and cost.

• The word “coumarin” itself derives from the Tupi word for the tree.

• In ancient rituals, tonka beans were burned to purify environments or offered as symbols of gratitude.

Cumaru and Environmental Responsibility

Cumaru represents a positive example of sustainable biodiversity use. Its seeds are collected without cutting down trees or damaging the forest. Because the seeds are simply gathered from the ground, cumaru extraction supports local livelihoods and helps protect the Amazon ecosystem.

Supporting such natural resources also encourages green entrepreneurship and value-added products that go beyond deforestation-based economies.

Inspired by Nature: Skincare with Purpose

Just like cumaru seeds offer natural protective compounds, modern skincare seeks similar qualities — deep hydration, barrier support, and calming effects — especially in times of environmental stress or aging.

That’s where innovative skincare inspired by nature makes all the difference.
