Why is it better if the terpenes are derived from cannabis?
Is limonene effectively different if it comes from marijuana than if it comes from a lemon?
A given terpene is generally going to be the same whether it comes from one plant or another. In some cases, one isomer or enantiomer of the same terp may be found in one kind of plant, whereas a different one may be found in another (alpha-pinene vs beta-pinene for example).
The main problem is that unless they are very purely isolating the terpenes from the original fruit material, you do not know whether what you have is just terpenes. There are no test results provided on the website for any of the terpene products and in fact, no terpene test results I could find anywhere on the site!
This is not encouraging at all. If they are not testing their products, there is no way you can tell if the terpenes used were sufficiently isolated, or if there's a bunch of other shit from fruit and vegetables and herbs in the product too that came along for the distillation ride. Also heat used in crude distillation can turn one terpene into another (or worse, some other decomposition byproduct), so what was put in in the first place may not be what the vendors thought it to be.
Another thing I've noticed is there is no way no way to establish whether the products in question are nothing but CBD with 10% various terpenes because there are no test results for terps. More to the point, there's no way to know whether the 10% terpenes they put in there aren't a handful of individual terpenes present at levels too high for safe inhalation.
Not enough information is out on the safety of using pure terps yet. Anything food grade is likely too potent. You want the ratio mother nature created. Blue River does that and I feel safe using it. All these other snake oil salesmen scare me.
has shared lots of info in various threads. Maybe he can jump in and help. He taught me to be more cautious and not just dive into pure terpenes. A-pinenne for example is dangerous. I had to toss some stuff I bought from Trinity (stay away).
There are definitely other terp producers out there that seem legit, but this one doesn't give enough detail and sufficient testing paperwork to convince me unfortunately.
