By the way if you or anyone is into essential oils, there are combinations they like to call the "morphine bomb" - again only anecdotal evidence of course, and more of a 'joke' to call it that, apparently often propagated via social media, which isn't exactly comforting.
One example is 15 drops each of lavender, peppermint, and 10 of chamomile, marjoram, lemongrass",
another "5 drops Frankincense, Copaiba & Idaho Balsam Fir",
a 3rd "6 Drops Marjoram Oil or Oregano and 6 of Frankincense",
a 4th "20 drops of marjoram, lemon grass, copaiba & frankincense.
A video called - "is it safe?" which seems OK,
says of this 4th mixture, only copaiba & frankincense are OK for pain,
but not as highly concentrated as often rec.,
she also says not to ingest these as often recommended, but to use topically.
When they (not just her) say high dilution they mean high concentration, irritatingly to me.
She says "all the rest are dangerous, buy mine" ;-).... so watch out doubly or better leave it be...
Now I know why I never wanted to dabble with this stuff - I'm much too sensitive.
But lavender was sometimes a nice placebo for sleep.
And tea tree oil for most things sore helps me a lot, strangely despite my sensitivity.
