Great question.

1 tablespoon of ground nutmeg is about 7 grams and contains about 10% nutmeg essential oil. 10% of 7 grams is 700 mg of essential oil. Only about 3% of nutmeg essential oil is actually myristicin, so that’s about 21 mg of myristicin per tablespoon, a very small dose. I’ve seen Erowid state that nutmeg has as much as 200 mg of myristicin in 10 grams of nutmeg, about 140 mg per tablespoon, but I can’t find any good data to back up that claim. I don’t think it has nearly that much.

So basically you’d use nutmeg essential oil at a dose 1/10th of the nutmeg powder dose used, since nutmeg powder is about 10% essential oil. So for 1 tablespoon, or 7 grams or powder, you’d use 700 mg of essential oil, which comes to 0.777 ml of essential oil. 0.777 ml of oil weighs about 700 mg. That's considered a light dose. Anything from 0.5-1 ml of oil is a light dose on its own. But in this mix, it should be much stronger, if this recipe actually works as advertised.

Elemi oil is roughly the same potency as nutmeg oil, but the effects are more fickle. I mean that sometimes it just doesn’t work, unless other things are taken with it (like whole milk for example). It’s very likely that this mix contains all the required compounds to jumpstart elemi oil’s psychedelic effects without the use of whole milk. The nuts in the mix contain fats and oils which should help the elemicin get digested properly. And the black pepper and the turmeric contains MAOIs which should protect the elemicin and/or boost its potency.
