The essential oil is a kind of short cut to making infused oil and, as stated above, I'd recommend the transdermal route above all others. Oil infused with whole nutmeg nuts may contain additional beneficial compounds (e.g., lignans) which will not be found in the essential oil.

My view is that the toxic delirium constitutes excessive dosage. Pain relief, euphoria and sensory enhancements are a good place to get to. Others may disagree, and, as always - YMMV.

It bears repeating - an understanding of metabolic enzymology is very helpful if considering working with this material. Due to the significant lipophilicity of the active or precursor compounds, combined with the metabolic transformations they undergo, the effects of nutmeg can linger for a very long time. I have warned elsewhere of the insidious characteristics of a nutmeg comedown. Be prepared!
