Depending on what kind of container you got it in, I'd say stir or shake the crap out of it to speed things up.
There's only a few simple things that help speed up the extraction process:
- stir, shake &/or swirl
- mild heat....i.e., warm solution, but NOT HOT!
- finely powder herb before putting in alcohol
I do all three with a magnetic stirrer/hotplate and a Magic Bullet. I get what I want in 3 days. So.....that doesn't really help someone without a stirrer/hotplate.......
What I would do...is powder (or maybe not; powdering could present filtering problems later on) the blue lily and put it straight into the bottle of IPA. No new container or anything. Just powder, straight in and shake the crap out of it. Shake the crap out of it over 5-7 days. That should do it fine, I think.
Most importantly, don't worry too much. When it's good your intuition should kick in, saying, "Uhmm, yeahhhh. It's done fool."
