What a great research update! Frankincense essential oil has demonstrated ability to kill cancer cells in every organ cell line on which it has been tested, while causing no harm to healthy cells. Now, Frankincense essential oil has been show to specifically disrupt the development of breast cancer cells, with a note in the research abstract that "the essential oil may be effective for advanced breast cancer".*

Frankincense Frankincense resin, from which the essential oil is distilled.

In research published in BMC Alternative and Complimentary Medicine, essential oil steam distilled from Boswellia sacra tree resin was used. Frankincense is the dried resin commonly from one of three Boswellia tree species, the others being Boswellia carteri and Boswellia seratta.

Previous studies showing anti-cancer properties of Frankincense essential oil have utilized both carteri and seratta Frankincense types (the choice of species has not been mentioned in any of the research abstracts, as far as we're aware). For this reason, we're fairly certain the three Frankincense essential oils should be interchangeable for this potential therapeutic action.

The research also notes that the essential oil distilled under conditions which extract a greater amount of higher molecular weight constituents was more effective at inhibiting cancerous cell growth.  We actually carry CO2-distilled essential oils of both the Carteri and Seratta types (as well as a blend of the two), specifically because the CO2 distillation process is known to extract these higher molecular weight constituents into the oil. (You may see all our Frankincense offerings here).

In fact, Frankincense CO2 was the first of the CO2-distilled oils to be broadly accepted by 'medical' aromatherapists, who traditionally held that only steam distilled extracts be called 'essential oils'.

In summary, the addition of Frankincense essential oil to the cell medium caused disruption of cancerous cell growth, but had limited effect on 'immortal' healthy cells. As the research abstract notes: "All three human breast cancer cell lines were sensitive to essential oil treatment with reduced cell viability and elevated cell death, whereas the immortalized normal human breast cell line was more resistant to essential oil treatment."

Should you like to indulge in further reading, use the search tool on the site and search for "frankincense cancer". You will be presented with a long list of research studies which appear to confirm that Frankincense essential oil may hold great promise as a potent cancer therapy.
