Another one of my favorites?

SAGE OIL!

It can help improve memory, concentration, and word recall in patients with brain injuries. It is especially helpful for those with aphasia, a condition that can occur after a traumatic brain injury (TBI) in which survivors have trouble retrieving words from their memories. Sage oil can also treat muscle and joint pain, as well as headaches.
