Not all nutmeg oil contains the requisite elemicin and/or myristicin. Also, your metabolic enzyme profile might not be suitable for activating nutmeg.

Even then, don't expect it to be similar to tryptamines or phens. It's different. A low effective dose will produce mood elevation and sensory enhancement. Going above that level increases the likelihood of unpleasant side-effects.

Elsewhere on the forum, I've shared details of experiments with nutmeg tincture, which I've made using freshly ground nuts and 80% ethanol. Elemicin and myristicin are appreciably soluble in hot water, so you can just add the powdered nut (or mace) to some freshly ground coffee prior to infusion to obtain some level of effect with the minimum of effort.

Elsewhere, someone has described how they would make multiple extractions of powdered nutmeg in combination with decaffeinated instant coffee to reliable effect so you might want to have a go with that.

Meanwhile, read (all) this.

Take care, heed the warnings, stay safe!
