A new study reveals one reason why incense and spiritualism go together like zendos and zafus. Beyond the symbolic tradition of burning incense lies a biological benefit: it can help ease anxiety and depression. When scientists administered incensole acetate, a compound found in incense, to mice, the compound affected them in "brain areas known to be involved in emotions as well as in nerve circuits that are affected by current anxiety and depression drugs." Adds Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal, "This study also provides a biological explanation for millennia-old spiritual practices that have persisted across time, distance, culture, language, and religion--burning incense really does make you feel warm and tingly all over!"
