Compounds responsible for the aroma of cannabis and many other plants may offer a surprising new way to relieve chronic pain. Researchers found that several cannabis-derived terpenes significantly reduced pain in mouse models of fibromyalgia and post-surgical pain, with one terpene, geraniol, showing especially strong effects. Unlike THC, these compounds are not associated with psychoactive effects, making them a potentially attractive alternative for pain treatment.
If I’m not wrong, essential oils are rich in terpenes and maybe that’s what makes them useful as a pain treatment.
Essential oils are not useful as pain treatment.
I have friends that use them and disagree.
You have friends that have made a therapeutic ritual out of using essential oils which helps them only because the placebo effect can be very powerful for pain. Literally anything could stand in for the essential oils. Swap their oil vials out with convincing fakes and they’ll never know the difference because it’s the ritual of smelling and/or applying the oils that’s helping them, not any real physical mechanism of the compounds in the oils interacting with their biology.
