Frankincense has burned in temples from Jerusalem to Varanasi for over 5,000 years. Scientists discovered why in 2008 — its incensole acetate activates TRPV3 ion channels in the brain, producing feelings of warmth, transcendence, and reduced anxiety. Oud (agarwood) is considered sacred across Islamic, Hindu, and Buddhist traditions — its complex molecular profile of over 150 compounds creates an aroma that anchors the spirit.
