Ah, thanks mate. I have now confirmed from other sources that putting a regular dose of ground mimosa in room temperature water, and letting it sit for a a week and shaking the mixture everyday, is in fact, an effective extraction. (strain before using of course) Some people say as short as 3 days, some say two weeks needed for the mixture to sit. So I estimate one week. This way only a small amount of water can be used. One person just used 200 ml, ground mimosa in it, shake every day for a week, strain, take, powerful trip. Another person used the straining technique to fill three bottles of water. After two weeks, the three bottles were added together and boiled down. I guess that's more thorough. I thought I'd add that to the library of info.
My interest now is how to take it anally bc I'm pretty sure orally would be too strong. It's going to be harder to find someone who can give me their anal experience. I think it deserves its own thread.
