I never liked rue in large amounts. I honestly never ever felt any toxic effects from caapi at all. I never experienced any purging or nauseating effect from caapi, but with large amounts of rue i always had to puke and felt dizzy and uncoòrdinated. On the whole i have quite a strong stomach and hardly ever have to puke from any product so i figure that for most people, rue must be realy heavy to take in large amounts. But in small amounts added to caapi brews it can indeed add an extra dimension. I think this is because harmala's are very synergistic toghether.
For this reason, passionflower probably also combines very well with both caapi and rue.
