I get it at the local herb store. They only have it in 10 ml amounts there (but I don't pay shipping so it's cheap). It's pretty much all from the same source: the Philippines, so I doubt it makes any difference where you get it. Just make sure it's therapeutic grade.

Here’s another bit of info on nutmeg from Erowid at: Erowid Nutmeg Vault : Effects #1

That’s yet another quote making it look to me like elemicin is the hallucinogen of nutmeg and the other stuff is just toxic crap to be avoided.

Also what’s interesting about that quote is that it gives the dosage of elemicin at 70 mg for a decent dose of nutmeg. That’s much more than SWIM has ever tried of elemicin via Elemi oil.
