West Indian Bay Tree (Pimenta racemosa)
The West Indian Bay Tree (Pimenta racemosa) is an evergreen aromatic tree native to the Caribbean and central to Dominica’s natural heritage and agro-industries. Known locally for its fragrant leaves used in Bay Oil and Bay Rum from Dominica, this tree thrives in the island’s volcanic soils and humid forest zones. Its leaves and essential oils influence industry, culture, cuisine and natural wellness practices, making it a vital link between agriculture, tradition and export-driven small business development.
West Indian Bay Tree in Dominica
The West Indian Bay Tree originates from the Myrtaceae family and grows extensively throughout Dominica, particularly in areas such as Layou Valley, Syndicate, Penville, and former bay-leaf hubs like Petite Savanne. It typically grows 7 to 12 metres tall with dark green, leathery leaves rich in eugenol, the compound responsible for its recognisable spicy aroma.
- Climate: Thrives in humid tropical rainforests with high rainfall
- Soil: Prefers fertile volcanic soils with good drainage
- Growth Pattern: Can be wild or cultivated, often intercropped with root crops or citrus
Bay trees also play an ecological role by helping stabilise soil on steep slopes and supporting biodiversity in forest-edge farming systems.
Traditional and Commercial Uses
Bay leaves from Pimenta racemosa are the primary raw material in Dominica’s Bay Oil sector. Rural farmers harvest mature leaves, which are steam-distilled using traditional firewood boilers or modern stainless-steel stills.
The oil extracted is known for its:
- High eugenol content
- Deep amber colour
- Warm, spicy-fragrant profile
This oil forms the base of Bay Rum, hair tonics, balms and artisanal soaps sold internationally and in Dominican craft markets.
Culinary and Medicinal Applications
- Cooking: Used to season fish broths, stews and legumes
- Herbal medicine: Infused into teas for digestion, calm and pain relief
- Topical uses: Applied in oils or lotions for muscle relief and skin healing
These uses are part of broader traditional herbal medicine use, where the bay tree holds a central place.
Industrial Significance and Economic Value
The Dominica Essential Oils & Spices Cooperative Society Ltd. manages large-scale bay oil production and exports. Annual output exceeds 22,000 litres, supporting hundreds of rural families through leaf cutting, collection, and cooperative trade. The oil continues to secure demand in global fragrance and wellness markets.
