Some studies have shown the possibility of using essential oils such as citrus fragrance  or rose scent  to relief depressive symptoms. Interestingly, there is some work suggesting how sweet-smells could be used to treat depression by “fooling” the brain glucose level sensors . As in previous cases, BioEssence could facilitate the study of these effects in real-life and be used to provide more frequent interventions which are needed to achieve a long lasting effect.
