Well, new and exciting news in the world of Ebay. Jawah Original Herbal Incense Blend was dropped for a terms violation, the would not be more specific than that it fell under the drugs and paraphernalia clause. I asked them how my product specifically managed to violate their rules, and it took them a couple of days to get back to me. They were very polite in their response, and clearly still want my business. So the official answer is:

The term NOT FOR HUMAN CONSUMPTION, which they said may imply that it can be consumed! LOL.

Fair enough, warning has been removed from the label and product description. I just hope people don't actually try to consume it now! GASP
