Interesting, but somehow not surprising Thanks for posting this, pluran.
Without fail when I am flying out on a short haul work trip or facing a run of meetings on unfamilar ground I will reach for a vetiver scent to 'ground me' as I navigate unknown territory, so to speak, so in that respect I guess I'm subconsciously using it as a tonic of sorts, as the article suggests. Having said that, I just do not wear vetiver at all on a day to day basis . . .
I often wonder if ginseng will ever emerge in our fragrant world.
