Yes. From the Blue Ridge Wiki:Luthien wrote:I was wondering, are those Blue Ridge Mountains the same ones as in that song "the Trail of the Lonesome Pine" ?
[link]Blue Ridge Wiki wrote:[...] The mountain range is located in the eastern United States, starting at its southernmost portion in Georgia, then ending northward in Pennsylvania. To the west of the Blue Ridge, between it and the bulk of the Appalachians, lies the Great Appalachian Valley, bordered on the west by the Ridge and Valley province of the Appalachian range. The Blue Ridge Mountains are noted for their bluish color when seen from a distance. Trees put the "blue" in Blue Ridge, from the isoprene released into the atmosphere, thereby contributing to the characteristic haze on the mountains and their distinctive color.
This excerpt from the Blue Ridge Wiki is interesting because Salvinorin-A is composed of 4 isoprene units:[...] Trees put the "blue" in Blue Ridge, from the isoprene released into the atmosphere,
[link to PDF]The Kappa Opioid Agonist, Salvinorin A, Attenuates Locomotor Effects of Morphine but not Morphine-Induced Conditioned Place Preference wrote:[...]Once extracted, unlike other known hallucinogens (i.e., N,/V-dimethyltryptamine, psilocybin, mescaline, lysergic acid diethylamide, or ketamine), salvinorin A does not contain a nitrogen atom and thus is not categorized as an alkaloid (Roth et al., 2002).Instead, salvinorin A is considered a neoclerodane diterpene: a bicyclicorganic compound composed of four isoprene units.
Now, although isoprene in itself has no psychotropic properties (that I'm aware of), it may be that because I'm sensitized to Salvinorin that I also am beneficially affected by the isoprene aerosols, which are produced more in the warmer months as a strategy by many plants to "flatten out" the high and low daily temperature variation curve (you can read more about that in the isoprene Wiki). I can tell you subjectively that I feel much better in a bioregion like this, and on particularly warm days, the feeling is akin to the very early stages of a Salvia trip (but never goes beyond that -- or else all of the North Georgians would be driving their cars off the roads and walking dreamily off cliffs ).
The identification of the blue aerosol is new research, though, so its not surprising that I never saw it before. Back in the day, they would gloss over it as "an effect of transpiration". Well, duh! But, it's nice to know the actual compound and its relation to things I'm more directly familiar with.
