Plants have been used as food and medicine for thousands of years and that long history is valuable.
It is also where scientific language needs to become careful.
Pimenta racemosa, the West Indian bay tree, has a long tradition of use in the Caribbean and modern researchers are also investigating its essential oil and other plant compounds.
But traditional use, laboratory research and proven medical treatment are three different things.
Keeping them separate makes the story more useful—not less.
Traditional Caribbean uses of Pimenta racemosa have included preparations associated with a range of everyday health complaints.
The plant’s leaves are also the source of an aromatic essential oil that has historically been used in fragrance and other products.
These traditions help explain why scientists continue to study the species.
The chemistry is certainly interesting because Pimenta racemosa essential oil contains biologically active volatile compounds, including eugenol and other constituents whose properties have been studied individually and as mixtures.
A 2025 study examined the chemical composition of Pimenta racemosa leaf essential oil and investigated antioxidant activity and several enzyme-inhibitory activities in laboratory assays.
Those findings are worth paying attention to.
The essential oil of Pimenta racemosa has also attracted scientific interest because of the biological activity of its constituents.
A laboratory finding involving microorganisms does not automatically mean that the plant can treat an infection in a person. What this means is that there is considerable potential for antimicrobial activity, which is a solid foundation for future research.
There is a temptation with traditional plants to tell a simple story; People have used it for generations, therefore it works.
Science does not work that way.
Traditional knowledge can point researchers toward useful plants and compounds. It can provide hypotheses and It can preserve knowledge that might otherwise disappear.
This is perhaps the most important practical distinction.
Using a West Indian bay leaf to flavour food is not equivalent to consuming Pimenta racemosa essential oil.
Essential oil is concentrated.
Health Canada has assessed West Indian bay oil and proposed that certain DIY uses involving inhalation or skin application could pose health risks, while its assessment found that the food exposures considered did not pose a human-health risk. The assessment is described by Health Canada as not yet final on that page.
So the sensible approach is straightforward:
Cook with culinary leaves as culinary leaves. Treat essential oils as concentrated substances requiring appropriate safety information.
The most scientifically honest answer is: It has biological properties that are being investigated which shows promising results and when combined with the knowledge from generations of traditional use, it is safe to say yes.
