I once did a cold water extraction on 3 grams of MG seeds and also acidified the water to ph = 4 with a dash of 99% DL tartaric acid powder for wine making from ebay.
I put the finely crushed seed powder (ground up with short bursts in an electric coffee grinder) into an empty teabag then stapled it shut and put the bag in a liter of distilled cold water on top a magnetic stirrer for 45 minutes. I dropped the stirrer into the jar of water and suspended the teabag in the water by trapping the string from the teabag between the jar and closed lid. I put aluminum foil around the jar to shield it from light.
For 20 minutes I watched as a tornado of white polar actives exited the teabag and went into the water as the stir bar spun on high setting. The result was a crystal clear extraction (none of the nauseating non-polars got into the water as they are not water soluble) with tons of white polar actives in the water that looked like salt. So long as your extraction does not go on for too long, the nauseating nonpolars will stay inside the teabag. When the stirring stopped, the white polar actives (like salt) would congregate on the bottom of the jar 1/4" thick and would go back into suspension by shaking the jar with lid closed.
After 20 minutes (when I could notice no more actives streaming out of the teabag) I put the jar with teabag still hanging in it into the fridge for another 25 minutes to soak some more. I shook the jar about 3 times during that period. After the 25 minutes was up, I opened the jar and threw away the teabag. Then I took the jar of water and blended it in a blender for 3 minutes to help chop and mix the polar white material at the bottom of the jar into the water.
I drew up some of the crystal clear water from the top of the liter jar with a medicine dropper full of the water and put it in front of a 4 foot blacklight tube and it glowed an intense bluish-white color telling me that my extraction was successful.
I can't stress enough how helpful it is to test some of your solution under a blacklight. The indoles in the extraction glow bright whitish blue just as LSD does.
I drank the water and felt the effects in 2 to 2.5 hours. I went from a foul mood to profound euphoria--felt like the mental effects of LSD with the euphoria without many visuals, however my hearing and sense of smell was enhanced significantly. I was in a shopping mall when the effects hit--all the sudden I felt it coming on and I announced to my wife how good I was feeling. The women trying on clothes in changing room would come out to look at themselves in the mirror in the pavilion and they seemed to transform into models. I found it hard not to watch as the euphoria increased. We passed by several speakers blasting out music and I just wanted to stop and sit under the speakers because the music sounded so good. My hearing and sense of music was increased by a huge factor. We went to more stores and again I was super-impressed with music. It felt similar to a small dose of mdma. The anti-depressant effects were very high and I could not believe that the seed extraction was working so well. We passed by a bath and body and the smells coming from the store were again intensified. I was a grinning idiot from ear to ear. I went from a bad mood when I drank it to a state of ecstasy when it kicked in nearly 2.5 hours later, the transformation was amazing...I hadn't felt so good in a very long time. The extraction worked and the mental effects were amazing. I thank God for that amazing afternoon.
Would complement mescaline doses very nicely, plan to combine in the future.
In my on-going research to understand how hydrolization (water extract) of morning glory seeds work, I found this article by chemist Peter Webster very helpful (see pages 25-35).

Water extraction of the seeds was also the method used by the Shaman's for thousands of years.
In the article, the chemist who has had experience with the seeds describes how water extraction causes via epimerisation 3 conformation forms of LSA/iso-LSA to form instead of only 2 that would form by "eating seeds" hence the enhanced activity via water extraction when performed correctly. The chair form of LSD is then compared with the chair form of iso-LSA (formed in water after about 45 minutes to 1 hour) and conclusions are made. 3 ergine variants formed from ergine in the water over the course of an hour or so may just result in a mixture that is so effective according to him.
