The cascarilla tree — its biology, geography, harvesting, uses (traditional, commercial, scientific, and industry), and what it would take to establish a lucrative cascarilla processing/export business in The Bahamas.

The Cascarilla Tree and Its Bark: Nature, Uses, and Value

 

1. Botanical Description

Cascarilla refers to the dried bark of Croton eluteria, a small aromatic tree in the spurge family (Euphorbiaceae). The plant is native to the Caribbean region, including The Bahamas, and also grows in parts of Central America and other tropical areas. It typically grows as a shrub or small tree up to about 12–20 feet tall with pale yellowish-brown fissured bark, scanty lance-shaped leaves, and clusters of small white fragrant flowers (often in spring).

The name Croton eluteria reflects its botanical lineage: Croton from the Greek for “a tick” (referring to seed shape) and eluteria said to reference the island of Eleuthera in The Bahamas.

In the field, the bark is easily stripped from twigs and branches, then dried before further processing.


2. Growing Locations and Ecology

 

The Bahamas Concentration

The Bahamas, especially in the southeastern islands — Acklins, Crooked Island, Samana Cay, and Cat Island — is the world’s most valued source of cascarilla bark. This region’s dry, rocky soil and subtropical climate produce plants with exceptionally high essential oil content, making Bahamian cascarilla particularly prized in international markets.

These outer islands have sparse economic opportunities, and cascarilla has traditionally been one of the few viable commercial resources for local residents.

Environmental Requirements

The plant thrives in tropical or subtropical frost-free climates with well-drained soils, moderate rainfall, and long dry seasons. Although trees can grow wild, cultivation practices are increasingly being explored to ensure sustainable supply and reduce pressure on wild populations.


3. Harvesting the Bark

 

Traditional and Wild Harvesting

Historically, cascarilla has been wild-harvested. Harvesters walk scrubland and bushland searching for mature plants with thick bark. Once found, branches are cut, soaked in seawater (to soften the bark), dried, and then beaten or scraped to remove the bark. The remnants are bagged and exported for processing abroad.

This method, while traditional, is labor-intensive and inconsistent — and often results in low economic returns for harvesters because value accrues mainly downstream (in foreign processing and product manufacturing).

Towards Sustainable Harvesting

Recent projects, especially by government and community cooperatives, are introducing more sustainable practices — such as:

  • Training harvesters to strip bark without killing plants, allowing regrowth.

  • Encouraging organized propagation and small-scale cultivation to create reliable supplies.

  • Supporting cooperatives that manage harvesting to avoid overexploitation and improve income distribution.


4. Chemical Constituents and Uses

 

Phytochemistry

Cascarilla bark is rich in:

  • Volatile essential oils (about 1.5 – 3 %).

  • Diterpenoids (cascarillins).

  • Resins, tannins, terpenes (including pinene, limonene, thujene, vanillin).

Its essential oil is pale yellow to amber with a complex aroma that’s woody, spicy, and slightly peppery.

Traditional and Medicinal Uses

Cascarilla’s bitter, aromatic nature has led to a long tradition of use:

  • Digestive aid — historically brewed as a tea or tonic for indigestion, nausea, flatulence, diarrhoea, and general digestive stimulation.

  • Fever reduction — enjoyed as a traditional remedy in Caribbean and Latin communities.

  • Antimicrobial properties — laboratory studies suggest the essential oil has antibacterial activity.

Though traditionally used medicinally, modern clinical use is limited; official herbal pharmacopoeias describe tinctures (alcohol infusions) of cascarilla bark primarily as flavouring agents, not regulated drugs.

Commercial and Industrial Uses

The most economically significant uses of cascarilla and its oil include:

  • Beverage flavouring:

    • Cascarilla contributes the characteristic bitter aromatic note in aperitifs such as Campari and vermouth.

  • Essential oil for perfumery:

    • Its spicy, woody scent is used in perfumes, cosmetics, soaps, and colognes.

  • Food, beverage, and confectionery flavouring:

    • Bitter extract components can be used in candies, baked goods, and specialty drinks.

  • Other:

    • Traditional incense, insect repellents, and artisanal products.


5. The Value Chain and Economics

 

Export of Raw Bark

Currently, most cascarilla exported from The Bahamas is raw dried bark. The global destinations include the UK, Italy, France, Germany, and the USA.

However, this raw export brings limited financial benefit to local harvesters — often around US $6 per pound — while downstream markets command much higher prices for essential oil and finished products.

Value-Added Products

The essential oil — especially when refined, bottled, or infused — can be worth multiples per ounce compared with raw bark.

Local production of:

  • Essential oil:
    – Steam-distilled oil can fetch significantly higher revenue than unprocessed bark.

  • Finished products:
    – Perfumes, cosmetic extracts, bitters, craft spirits — all command higher margins.

could transform the economic equation in The Bahamas.


6. Can a Lucrative Processing Plant Be Set Up in The Bahamas?

 

Existing Local Initiatives

There are already efforts by government agencies, the Bahamas Development Bank, and community cooperatives to establish a cascarilla industry — including:

  • Organized propagation and farming of Croton eluteria to ensure sustainable supply.

  • Plans for at least two commercial essential oil distillation facilities.

  • Formation of cooperatives (e.g., Acklins Islanders Cooperative Society) to manage production and share proceeds.

These initiatives aim to move beyond raw export toward on-island value addition.

Requirements for a Successful Processing Facility

To establish a commercially viable cascarilla processing plant that can export higher-value products from The Bahamas, several components are essential:

1. Reliable Supply of Raw Material

  • Establish commercial cultivation and sustainable harvesting plans.

  • Nursery propagation to scale up plant numbers.

  • Cooperative agreements with local harvesters.

2. Processing Infrastructure

  • Distillation units to produce essential oil.

  • Facilities for tincture extraction and fractionation.

  • Storage, bottling, and labelling facilities.

3. Technical Expertise

  • Skills in botanical processing, quality control, and essential oil distillation.

  • Partnerships with scientific institutions (e.g., universities or Caribbean research bodies).

4. Market Access & Certifications

  • Organic, export, and safety certifications.

  • Sales and distribution channels into European, North American, and specialty beverage/perfume markets.

5. Business Organization

  • Cooperative models or private partnerships to provide capital and share profits.

  • Training programs for workers and managers.

6. Environmental and Regulatory Compliance

  • Sustainable harvesting plans to protect wild populations.

  • Compliance with Bahamian forestry, export, and agricultural laws.

If these elements are coordinated effectively, a local processing plant could capture significantly more value than raw bark export alone.


Conclusion: Potential and Outlook

Cascarilla (Croton eluteria) is a unique Caribbean botanical with a long history of medicinal use and commercial importance, especially in flavouring spirits like Campari and in perfumery. The Bahamas — thanks to its endemic, high-quality cascarilla trees — holds a comparative advantage in this niche market.

However, for Bahamians to benefit more fully from this resource, a strategic shift from raw bark export to value-added processing is critical. With organized cultivation, sustainable harvesting, investment in distillation and processing facilities, and connections to international markets, a cascarilla processing industry could become a lucrative economic engine for some of The Bahamas’ more remote islands.

A successful enterprise would not only increase export revenue but also diversify local economies, create jobs, and make better use of a natural resource that has historically been undervalued.


In short: Yes — with the right investments, training, infrastructure, and sustainability practices, The Bahamas could establish a lucrative cascarilla processing plant and industry capable of exporting high-value oils and finished products internationally.
