Rue will work, in VERY small doses. Because of other, slightly toxic alkaloids in Rue I would not recommend it for daily use unless a Manske extraction was use, extracting only Harmaline and Harmine.

Caapi on the other hand, can be used daily withtout any problem.

I have used unreduced Caapi for depression on MANY occasions.  Because I am not going for full MAO inhibition there is little worry about MAOI issues.

100grams in 1/2 gallon of water, cooked for 3-4 hours, strained, and cooked again in 1/2 gallon water for 3-4 hours will get most of the alkaloids you want. Smaller amounts can be used, and the water ratio is not exact.  Just cook it until you are not getting yellow/brown water anymore. Do an eggwhite filtration on it and you will have crystal clear golden colored Caapi tea.  Add sugar to taste and enjoy 1-2x daily.  A small tea cup is more than enough.  It takes 2-3 days for the antidepressant effects to be felt fully, but even after the first dose a change can be felt.

Caapi over Rue every time.  Yeah it's a bit more expensive, but really, you get what you pay for on this one.
