So we know there are many many different types of repellant compounds that can be isolated from plants, some of those compounds have a better repellency protection percentage. It is not surprising that many terpenes found in other plants in nature are also found in cannabis. Limonene, and linalool for one. Both are terpenes synthesized by cannabis, actually those were the dominant terpenes in my recently harvested KC-45 because it tastes purely of lemon spice (lemon flavor from limonene and linalool is the spice flavor). So in essence, a plant that can synthesize higher concentrations of these terpenes and store them into the stems, and eventually through the glandular secretions in flower will have the higher success rate in nature. The land-race species that make up the Brazilian hybrid in KC-45 are a testament to that, since quite clearly terpene production begins even in the vegetation cycle. So different terpenes have different repellant properties and percentages... So by harnessing the terpene of another plant, and incorporating it into the system of our chosen plant, we can transfer some of those repellant properties. I think a lot of the modern-day hybrids that exist today are weakened in that sense, that they don't start true terpene synthesis until they are a little older. Perhaps that's another benefit of KC-45 and its known hardiness. Anyway here's the link, anybody can see how many different repellant compounds come from so many different plants, the list goes on, this link is a reference link in the paper that I previously posted, apparently rosemary was not part of their study.
Plant-based insect repellents: a review of their efficacy, development and testing (See Table 1 in Essential Oils part!) But they did say in one of the charts that Rosemary repellant compounds are slightly more hazardous than some other plants, but over all nothing to be worried about since it's all relative. One might be inclined to ask, "Well they're only talking about mosquitos there" ... Well mosquitos are still part of the phylum arthropoda and so the receptors in their brains are all very similar. So these actual large organic compounds we call terpenes are extraordinarily useful to use in many many different ways. Some even reason specific terpenes to exist in the cannabis which synergistically works together with CBD, THC in very interesting mechanistic ways we are still trying to understand as a species, and how humans could have such a unique "lock-and key" for the acceptance of a CBD, or THC molecule in our brains. The brain produces synthetic analogs of CBD, and THC and bind to a very similar if not the same CB-1 or CB-2 receptor, so it really means this ancient plant and humans are ment to live together and co-exist. For instance, when the birds eat my Ghost Peppers, it's not hot at all for them! That's because they don't have a receptor in their brain for the compound capsaicin. The concept of terpene synthesis is one of the most fascinating concepts in all of plant biology, however the fact we have a plant producing some of the most intricate medicine known to man is something that shall not go unnoticed by man. There's still so many different things to be worked out, since we are constantly evolving side by side with the plants. When we start discussing the chirality of the terpenes, it gets really interesting. We can have a different geometric conformation of the molecule and have it produce a completely different therapeutic effect in the brain. For instance, all it takes is one methyl group (CH3) or hydroxy group (OH) to be in a different position, and that can be the difference between life and death. Literally. One isomer may kill a human, the other may work very well as a beneficial medicine, as plants evolve, I can imagine their terpenes may also evolve into different molecular analogs which will be tested by evolution, sometimes things work, sometimes they don't. Cannabis is on a good track, but I still think the outdoor land-race genetics are the ultimate place for the evolution that still needs to occur. I think there are some interesting issues involved in polyploidy that we are yet to explore, but we have definitely seen it occur in cannabis. The original amino acids that formed in the primordial soup eons ago were of a particular chirality, if it was not for the exact geometric structure of those acids, life would not exist. So I suppose it's sort of that cosmological evolution, trying each and every single possibility (brute force) until something works. Leads us to the "Biological Cosmological Evolutionary Theory" which contends thats solar systems, galaxies, and the Universe are actually alive - by all definitions they are! Things that are alive reproduce, they also have a set of instructions for that reproduction, and things that are alive also eventually go extinct. So it is fascinating to be on this nested little Blue planet apart of multi-verse of infinite possibilities. Since time will never end, and space will never end, that leaves us with infinite possibilities. Combine that with the multi-verse properties, we can conclude that exact copies of ourselves, and are plants exist somewhere else right now. Which could theoretically be connected through a worm hole!
I'll stop this little rant here, and leave this link about Rosemary.
Larvicidal activity of essential ext... [J Am Mosq Control Assoc. 2013] - PubMed - NCBI Time to Puff another bowl and reminisce about things. I figured the threads were a little slow right now so I figured on writing something, this will give someone else something to read later.
