The Essential Properties of Frankincense Essential Oil
by the Doctor Matteo Politi
Pharmacological activity
The smell of resin and dust of incense, as well as burning incense, has been linked to a number of health effects since ancient times.
Furthermore, incense and its fumes are used as a means to induce positive psychophysical effects and well-being, not only in an ecclesiastical context but also in traditional medical applications.6
Several works have described the antitumor, antimicrobial, immunomodulatory, anti-inflammatory, hypoglycemic, antiasthmatic, antidiarrheal, hypolipidemic, antidiabetic, hepatoprotective and antiviral effects of different species of Boswellia.7
Anti-tumor activity
The anti-tumor activity of frankincense essential oil has been tested on numerous cell lines using various experimental models, demonstrating the considerable interest that this natural derivative arouses with regard to this type of pharmacological activity.8–11
Antimicrobial activity
The antimicrobial activity of frankincense essential oil has been tested on various pathogens including Staphylococcus aureus, Bacillus cereus, E. coli, Proteus vulgaris And Candida albicans showing good to moderate effects depending on the strain tested.5,12
Phytochemical profile
There Boswellia sacra And B. carteri They are generally recognized as a single species, although highly variable, showing differences in morphology, growth form and resin chemistry, and are thus considered by various authors as separate species.1,2 The yield of essential oil obtained by hydrodistillation of the resin (incense) of Boswellia sacra collection in Oman was found to be 5.5% (volume/weight).3 The essential oil was characterized by the high content of monoterpenes (34) which constituted 97,3% of which p-cymene and limonene were the main constituents. The remaining 2,7% was represented by sesquiterpenes (16) in which β-caryophyllene was the main constituent. The analysis demonstrated the complete absence of diterpenes.3 In another sample from Somalia, two sequiterpene ketones were also identified which, although present in trace amounts, contributed significantly to characterising the aromatic profile of the sample in question.4 However, a comparative study on 20 different samples highlighted the remarkable phytochemical variability of frankincense essential oil; in particular, considering the main constituents, the essential oils were qualitatively similar but showed a remarkable quantitative variation for some main components including α-pinene (2.0–64.7%); α-thujene (0.3–52.4%); β-pinene (0.3–13.1%); myrcene (1.1–22.4%); sabinene (0.5–7.0%); limonene (1.3–20.4%); p-cymene (2.7–16.9%) and β-caryophyllene (0.1–10.5%).5
