Boswellia sacra and its relatives (Boswellia serrata, Boswellia carterii) produce the resinous sap that, when it dries in the air, becomes the substance known as frankincense or olibanum: hard, golden tears of resin that burn with a distinctive, complex fragrance that has been central to the ritual life of the ancient world for at least five thousand years.
Frankincense has been burned in Egyptian temples, Hebrew ritual, Greek and Roman religious ceremony, Buddhist practice, Christian liturgy, and Islamic ceremony. It was one of the gifts brought to the infant Christ in the Nativity story. It is still burned in Catholic and Orthodox churches, in mosques, in Buddhist temples, and in the ritual practices of dozens of contemporary spiritual traditions. The smell of burning frankincense is one of the most cross-culturally recognized sacred fragrances in the world.
Why Frankincense for Ritual
The question of why this particular resin became so universally sacred is interesting. The fragrance compounds in frankincense (particularly the incensole acetate) have been shown to have genuine neurological effects: studies have found that burning frankincense produces anxiolytic effects and may directly affect the brain’s mood-regulating systems through inhalation. The use of frankincense in sacred spaces may have served a pharmacological as well as a symbolic function: creating neurological states conducive to prayer, contemplation, and ritual experience.
The Medicinal Dimension
Boswellic acids (the primary active compounds in frankincense resin) are potent anti-inflammatory compounds with specific mechanisms that are different from and in some ways complementary to conventional anti-inflammatory drugs. Multiple clinical trials have found Boswellia serrata extracts effective for osteoarthritis, inflammatory bowel disease, and asthma. This is one of the most medically substantiated uses of an ancient incense plant, and it has led to standardized Boswellia preparations becoming significant anti-inflammatory supplements.
Using Frankincense
As incense, in an oil diffuser, or burned on charcoal in a ritual or meditative context: this is the oldest use, and the neurological effects through inhalation are real. As a standardized oral supplement (Boswellia serrata extract): for anti-inflammatory applications, particularly for joint pain and inflammatory conditions.
