Frankincense was a big part of the mix in the Jerusalem temples. The ingredients are listed in one of the mishnas, as I remember, though, the proportions were a gigantic secret. (But memory is porous). I *do* remember studying a passage in the Talmud that discussed whether or not a person exposed to the smoke of the incense in the temple precincts was guilty of an infraction. The conclusion was that he would not be, so long as he derived no pleasure from it. As one who doesn't like incense to begin with, I would have been safe.
