I believe I got the "scoop" on Mangoes from Ed Rosenthal.
Let me see if I can locate a link.

*Edit IN*
Haven't been able to locate his blog post on this yet (though I'm nearly positive I read it posted on CC's front page a while back) but did find this so far...

While I was in Nimbin recently at the 2008 Mardi Grass, I had the opportunity to sit and blow a joint with Ed Rosenthal. We got to talking about Terpenes, with particular regard to a chapter in Ed's latest Book, "The Big Book of Buds Vol. 3", called 'The Secret Chemistry of Cannabis Odors and Highs'.
The discussion led to a Terpene known as Myrcene, which is the most prevalent Terpene found in most varieties of Cannabis, but not found in hemp. It is also present in high amounts in mangos, hops, lemon grass, West Indian bay tree, verbena and the plant from which it derives it's name Mercia.
Myrcene appears in small amounts in the essential oils of many other plants.
It's odor is described as clove-like, earthy, green-vegetative, citrus, fruity with tropical mango and minty nuances.
Without going into too much detail from the book, Ed explained that the presence of Myrcene was an important factor in the quality and enjoyment of the high from smoking certain Cannabis strains, particularly those strains that came from tropical climates...namely Sativas.
Ed went on to tell me that it was possible to enhance the quality of the high from a low potency bud, through the addition of Myrcene. He went on to say that this could in fact be tested and verified. And this is how he told me to do it.
Say I had a nicely grown bud that was lacking in the 'Zing' department when smoked. If I was to eat a Mango one hour before smoking the bud, Ed said the addition of Myrcene to my body from the mango, would have a profound impact on the quality of the high, and I would notice the 'Zing' that was missing, had I just smoked the bud without having eaten the mango.

Yes folks, you heard it here. You can improve the quality of the high from a bud you smoke, if you eat a fresh mango ONE HOUR before smoking!

Yep... that is true.

You can improve the quality of the high from a bud you smoke, if you eat a fresh mango ONE HOUR before smoking!

Myrcene is found in large quantities in Cavalo, Rosa, Espada, and Paulista mangos!

Thanks Weedy, this is great stuff

Now, I'm off to buy a few mangos ...

two books you guys should read are:

"The Pot Book" and Ed Rosenthal's "Marijuana Grower's Handbook".

Now is there any way to infuse this Myrcene into a growing plant?

To infuse it NATURALLY???

I dunno, but you can do practically anything to plants with GMO (ask Round-up about their pesticide-resistant corn)... always unforeseen consequences with genetic modification.

I wonder if a mango extract (i.e. tincture or essential oil) would contain the necessary compound? If it did, then I wonder if its "high-boosting" properties would work when combusted or inhaled? If it doesn't have to be ingested in order to work, one could potentially include the extract with the herb to be smoked and/or put it in your water pipe to be inhaled along with your bong-rip.

Total musings on my part; for I am neither a chemist nor horticultural scientist/botanist.

Nonetheless, a very interesting question
