A further update here: after transdermal usage of nutmeg-infused olive oil, my levels of back pain have been significantly reduced. This corresponds with how nutmeg essential oil is used in aromatherapy, of course. I'll be keeping an eye on how long this pain relief lasts. The active portion of nutmeg volatiles seems to have a pretty long half-life in the body as it's quite lipophilic (unsurprisingly, having been extracted with oil).

This morning, about 48 hours after the initial application of the oil, hypnopompic visual activity was still above baseline levels by a noticeable amount.
