When I was visiting my relative who
fell off a cliff I happened to have a bottle of verbena tincture with me, so I gave it to him before I left.
I wasn't originally planning on giving him some but after I spoke with him I learned he had a damaged nerve in his face and I thought the verbena might help since it's a nervine.
We of
course can't say whether it expedited his healing or not, but the nerves were doing much better after. I also have no idea how often he took the tincture, but I do know he was taking it.
(It was a
local variety: Glandularia Bipinnatifida)
The more commercially available verbena would be Blue Vervain (Verbena Hastata)
