I'd typically do three swift-ish (20-30 mins), hard boils on whole seeds, and even then got a surprise flooring from a final combined boil on a week's worth of aggregated 'spent' seeds. Looks like you'd get by on 5g doses with a bit of a shaping up of your brewing method.
Wouldn't it be nice to get twice the mileage from these precious seeds? I wonder if you'd notice a difference in qualitative effects, though. Do you have any experience with any of the three principal alkaloids separately?
Do you have some more specific comments on your experience of the auditory and music appreciation qualities of rue because, you know, thread title…?
