I feel there's something to the plant but she is shy, so to speak. Mostly the effect is anxiolytic and mildly sedative, but there's kind of a secret doorway being hinted at both from the effects on dreaming - the rue/eschscholzia oral combo was taken prior to seriously the most impressive dream in richness and clarity as well as emotional affect, yet may have come 'merely' as a gratuitous grace - as well as some of the times I've smoked various parts of the herb (particularly stamens), sometimes with cannabis and sometimes with harmala (but neither for a long time now).
It very much seems like the stars have to be aligned right for an interesting effect to occur, or perhaps a rapidly developed, long-lasting tolerance to any kind of high, as I've never replicated the pleasan, moderate buzz I got from taking slightly more than the recommended dose of capsules (as a proprietary herbal product) either.
