Frankincense, derived from the resin of Boswellia species, has a long history of use in traditional medicine and spiritual practices, particularly in regions of the Middle East, Africa, and Asia. Its use for emotional sensitivity—manifested as a means to calm the mind, reduce feelings of stress, and promote emotional balance—derives primarily from traditional and anecdotal sources. Frankincense has been burned as incense in religious and meditative contexts for thousands of years, believed to purify the space, calm the spirit, and promote a sense of peace.

Scientifically, while some studies suggest frankincense essential oil may have anxiolytic (anxiety-reducing) or mood-stabilizing effects in animal models, robust clinical trials in humans are lacking. The aromatic compounds in frankincense (such as incensole acetate) have shown activity on certain ion channels in the brain associated with mood and emotion in preclinical studies, but these findings do not yet translate into established clinical use for emotional sensitivity. Therefore, the primary justification for using frankincense in this context remains traditional rather than scientific, and the evidence supporting its use is modest, largely relying on historical and cultural practices rather than rigorous modern research.
