That does sound potent, and it rather reminds me of Shulgin's caution that there's no such thing as a casual experiment. It also suggests that there's something in the acacia synergising with the rue.Man this stuff is really potent. Made a decoction of 60g ACRB + 30g Rue via pressure cooker and reduced it to about 100ml. Took 5ml expecting a slight buzz. An hour later I started feeling a little disoriented so I sat down and it looked like my legs were melting into the seat. I guess that would work out to roughly 1.5g of rue with 3g of ACRB.
Now you have a blessèd potion - use it wisely!
