I purchased mullein extract tincture when I realized a particular vendor did not sell the leaf itself. Would there be any difference between using mullein leaf and infusing b. caapi leaf with mullein extract?

The reason people use mullein as a carrier is because it's fluffy, inert and burns evenly, along with it's natural expectorant qualities. I don't really think it makes sense to infuse your caapi with a tincture, but a few drops down the gullet before you take your hits can be helpful and effective.

Mullein should make your changa easier to smoke... the more you use the better - and it is a powerful lung herb that compensates for the harsh DMT smoke. Not sure how well a tincture would work... maybe you can tell us!

I cannot comment on the tincture, because I shortly thereafter purchased mullein leaf and it worked a charm. It was precisely the missing link between the DMT vapor and my weak, faux leather lungs.

The tincture works great. Squirt an eyedropper full down your throat just before and those hits will go down like butta.
