Today I had to focus - more so than usual.
I googled "essential oil focus" - "essential oil concentration" - etc...
There are several great blend ideas.
I chose Peppermint - Frankincense - Orange.
Frankincense - 2 drops
Peppermint - 5 drops
Orange - 5 drops
In the diffuser and the office smelled wonderful! And I got a lot accomplished!
