Hey Josie. I suggest no more than one drop passionflower per twenty drops to thirty drops of regular nic juices. Here's what E-cigarette forum member grim_piper posted on 6-08-2010 regarding his passionflower sojourn......
"So in my promise to keep you updated here goes:
No adverse health reactions after two weeks.
I'm using about a drop per milliliter when the oral dosage on the bottle is 20-30 drops, thrice daily, so it's not a particularly high dosage.
I've eaten liver, fava beans and nice chianti with no headache etc, so at this dosage the effect of an MAOI-b and a regular diet doesn't seem to effect me.
No increased sun sensitivity.
My blood pressure is lower than when I started(107/65 on average) and the shortness of breath I had experienced before is greatly reduced. I'm wondering if those were more due to anxiety than overdone nicotine and PG.
I vape less and do not freak out if my e-cig is not at hand.
My cravings for analogs are practically nil and my mood is better.
I had two drags off a friend's cigarette about a week ago and handed it back with no desire to continue.
My only complaint is that the tincture I'm using seems to leave a residue on the cartomizer and has to be washed out more often.
So, for me, this seems to be working. I do not recommend it for others without severe caution to take it slow and monitor any possible adverse reactions. Read up all you can on harmine and related alkaloids as much as you can before you try any experiments."
I followed his lead with the passionflower mixture of one drop per twenty to thirty drops with e-liquid and got similar results. According to the above link, passionflower contains Quercetin as the principle whereas tribulus's principle is from the same as that of tobacco! ( Harmala / Harmine / harmalol )!! With the success I've had with passionflower, I'd have to be crazy not to give this tribulus tincture a try. I appreciate Tetsab and Tescela's prudence in this matter for everyone concerned, and I too am a little weary of possibly freebasing a steroid (although Native Americans seemed to do okay with it), but if people have been taking spoonfuls of the stuff forever, then how could one tiny drop in a mixture of twenty for a whole day be so dangerous not to mention that the drop is at least fifty percent diluted?
With that said I highly doubt I'll end up in the morgue as a stiff. More likely I'll just end up with a stiffy. Maybe both. We'll have to wait and see.
