I think it’s very odd how I’ve always wondered this, and now that I see it, it makes me realize something. If it really was bad for these reasons, there would be a warning to stay away from it. The one thing that makes frank interesting is the fact it has hallucinogenic properties and it’s been in spiritual and religious ceremonies for 3,000 years at least.
I think the only reason people don’t use it, is because it’s innocent seeming. It probably has much use, but only if you close off your room and fill it with the incense smoke (ancient people used to inhale the fumes of incense, I prefer doing it this way). If magick is about getting in the mood, it may be hard for certain people to evoke a nasty demon with the smell of frankincense resin burning.
"Accounts from the ancient world make frankincense sound like a cross between aspirin, penicillin, Xanax and Viagra, with a touch of duct tape and magic. "
