both rue and caapi are harmala sources..rue is largely harmine and harmaline, and some pinoline..and other harmalas..caapi is largely harmine and THH, and some harmaline and other harmalas.
DMT is in mimosa. There is no DMT in rue. Both rue and caapi contain harmalas as the maoi's.
Your brew at 30g of caapi with that much mimosa may be enough to activate the mimosa..but it will be short lived and wont have the same glow at ayahuasca with say, 60-100g has..ayahuasca is about the caapi in my opinion. If you only use just enough harmalas to activate DMT, than it seems to feel less empowering in my experience. I dunno how else to explain it. The mimosa may very well be active but it might just be a strong DMT flood that is short lived without the dreamy qaulity of realistic visions that larger doses of harmalas provide. The afterglow is stronger with more caapi as well as the "healing" I find.
