I absolutely despise companies like Young Living and doTerra, but like you mention, essential oils can be purchased elsewhere and for much cheaper.

Rose is my favorite as it’s Mother Mary’s flower. I usually use incense but also sometimes dab a little oil on my wrists as a perfume.

Frankincense and Myrrh I use incense instead of oils, because I use those in prayer.

I’m highly allergic to vanilla and it’s in almost everything.
