Hmmm, I get it now. It's a tough situation... if I were you I'd just keep doing it like you're doing it now, maybe even lose the wikipedia link (since it could be construed as a hint), stress that it's an incense only and all other uses may be illegal (or not, maybe it would be better to not mention it? IANAL), and let all your sales come from word of mouth.
After all, do you really want to build a business around this? You're playing with fire. I've read a few horror stories about the FDA freezing entire businesses with little or no chance of appeal. The legendary Gary Halbert (RIP) I believe stopped dealing with anything like this in the 80s because of them. But if you sell it as incense only and explicitly warn against all other uses (and IANAL and IDPOOTV so obviously consult one) you could just keep this as a nice passive-ish stream of income that'll grow naturally for years.
You will probably want to delete all of these comments, too :)
