3g of rue is exactly perfect for maoi functionality.

The mhrb amount im unsure of - 3g at say 1% spice plus the oxide and jungle - lets put it at 1.5% tryptamines just to be on the optimistic side.

that would be 45mg of tryptamines - no clue on what the oral dose is but iv heard of brews that only contain 30mg of spice but i think they often have much bigger maoi doses.

id say just go for it - grind up everything really fine and cook it with some lemon juice.

I have never done aya so im probably not the correct person to answer this tho.
