Medieval mix is just heavenly. The scent is really well balanced and can be diffused for cleansing the air of harmful pathogens as is, or I like to add a couple of drops of lemon for a more cleansing scent. It is one of the "thieves" style of blends and of all that I have tried I would say that this one smells the nicest. Can be used in a diffuser or for immune protection use a carrier and apply to bottoms of feet and along the spine. Aura Cacia oils are good quality and reputable, also the price point is good (especially on Iherb). I will keep coming back to this one.
I love the blend of ingredients and while I'm not sure why this is called "Medieval" -- maybe it's in the product description and I forgot -- but it does smell a lot like a bunch of fresh herbs, with the lemon, lavender, red thyme, tea tree, rosemary, and other oils. It's very refreshing and clean smelling (to me), like a herb garden in full bloom. It's nice in a diffuser or in a homemade room spray (my top uses). The package arrived very securely wrapped, so no danger of it breaking. I suspect it leaked the tiniest bit, because it did have that herbal smell on the outside. Maybe a few drops trickled out. Still, it's good. I'll have fun using this and enjoying the invigorating herbal scent.
