I don't mean to thread-jack, but I also have a question about morning glories and I figured it would be better to ask it here than to start a new thread.
Anyway, my yard will be absolutely COVERED in Ipomoea purpurea this year. Stuff is worse than kudzu if you ask me. Of course, it wouldn't be so bad if I knew it had LSA in it. These are the ones with purple flowers, occasionally pink or white, but mostly purple. The seed pods have six seeds in them, sometimes five.
I've experimented with them three times so far, but this was last year and the year before, so my memory of these experiments is faded.
-2012: I ate 100 black (ripe) seeds raw and felt "off" some time after eating, but this feeling passed and I wrote it off as placebo. I felt some slight nausea, but nothing too bad.
-2013: I read somewhere that white (unripe) seeds were more potent and caused no nausea, so I decided to give it a try. I picked 250 unripe seeds and ate them raw. The taste wasn't nearly as bad as the ripe seeds, so I chewed them more thoroughly this time. I got no effects at all from this, not even nausea, so I decided to try again at double the dose.
-2013: I ate 500 unripe seeds the next day and had the same result as the 250 seed experiment. My stomach was pretty messed up the next morning, but that's about it.
After this, I decided that I should try 200+ ripe seeds after they ripened, but picking morning glory seeds is a tedious process, especially when you count every single one. I also wanted to do a cold water extraction on the next try, which involves grinding the seeds. That's another tedious process without a coffee grinder (I didn't have one at the time).
So, instead of doing this tedious process, I just decided to let it go and buy some HBWR seeds when I got the chance. However, I never did, so that curious itch never got scratched. I'm still very much interested in LSA, and still want to see what it's like.
Anyway... Is I. purpurea active? I remember searching for it, but I don't remember if I ever got a definitive answer. I just saw this thread and thought I'd ask here.
