I use almost all of those herbs you've listed in my home-made JWH blends.
No, they won't make you get any higher - unless its active obviously. I've smoked the stuff inactive before, de nada. (FYI - active = synthetic cannaboid infused, inactive = unchanged from original state, chemically)
In either case there has been discussion on this topic before, but more broadly about what other non-drugs (not drugs that alter you in anyway, such as benedryl, as that doesn't exactly potentate cannabis anyway technically) may work... try giving a search for it.
But the answer to the thread is simply: no, not really. It's good for making your stash last longer, though, that's for sure. Some herbs DO work a tad bit, but as I said, there is a thread out there somewhere (use the search engine) to find that thread. Try looking through threads that pop up with search words like potentiating, or potentate. I believe there is one in the mega directory as well.
