Between a 10x leaf/dmt blend versus using extracted harmalas in a blend, both were pretty similar in their potentiation with the dmt ime.

I get that you're not wanting to do a tek, understandable, but the various rue teks for harmalas aren't all that difficult. I think it's worth the bit of effort to have some extracted harmalas laying around.

You could use ground rue seed in your blend, but that's really not going to be all that effective if at all, versus actually using crude/purified harmalas.

You could drink a little rue prior to smoking, sure. For me I'd never drank a whole bunch before smoking, only about equivalent to .6-.8g of seeds, never drank much above that. I only liked having a little bit of harmalas in the system, not a full on dose of them.

Though if you're wanting to drink a stiff dose of rue tea then vape dmt, then go for it  , just be careful.., start low with the dmt.
